A2 1.4 TDI

More powerful three-cylinder diesel version of the nimble athlete with an output of 66 kW (90 bhp). The new model year can be recognised by a more striking service flap.

A3 1.6 FSI

The 1.6-litre version now also has petrol direct injection and a power output of 85 kW (115 bhp). Fuel consumption of just 6.5 l/100 km and a performance full of temperament: 196 km/h, 0-100 km in 10.9 seconds.

A3 3.2 quattro

A wolf in designer clothing: 184 kW (250 bhp) and the revolutionary Direct Shift Gearbox DSG make the A3 the unassuming athlete in the premium compact class.

Audi S4 Cabriolet

Two souls in one stylish design: while the convertible body arouses emotions, the V8 engine adds the sporty S4 driving experience of 253 kW (344 bhp). Aluminium suspension and quattro drive ensure safety and traction.

A8 3.0

The first six-cylinder engine in the Audi A8. With the 162 kW (220 bhp) alloy engine, this A8 rounds off the model series in powerful style.

A8 3.0 TDI

Used for the first time, the piezo inline injector technology of the common rail TDI engine puts Audi back in the lead in the diesel sector. Despite six-speed tiptronic transmission and quattro drive, the 171 kW (233 bhp) six-cylinder engine complies with the EU 4 standard.

The New Audi S4 Cabriolet

Maximum on an open-ended scale

Another Audi sports model with a strong personality is about to leave the starting grid: the Audi S4 Cabriolet. It combines the acknowledged qualities of the Cabriolet with the powerful V8 engine from the Audi S4 and the safety of the quattro driveline. Restrained visual changes underline its sports character.

Design and equipment

The new Audi S4 Cabriolet expresses its supremacy by adopting a deliberately restrained appearance. A closer look, however, reveals that this stylish, sporty body is indeed subtly different in its basic form and proportions from the remaining Audi A4 Cabriolets: the bumper has large air inlets, the xenon headlights have a titanium-coloured surround behind the glass and the outside mirror housings have been given an aluminium finish. At the rear, one sees the powerful exhaust tailpipes on both sides that are typical of the Audi S models. The Audi S4 Cabriolet runs on 18-inch cast aluminium wheels of S design with 235/40 R 18 tyres.

Inside this Cabriolet too, it is immediately identifiable as an S4. The instrument cluster has characteristic grey S dials and special dial needles. For the inlays, customers can choose between carbon fibre, piano finish, brushed aluminium and birch. The car's sporty character is emphasised by the three-spoke leather-covered sports steering wheel with S emblem. There are shift paddles behind the steering wheel on cars with the six-speed tiptronic transmission.

For firm lateral location and excellent comfort on long journeys, the standard sports seats have a wide range of electrical position adjustments; combined Alcantara and leather upholstery is used, and there is a lumbar support and an adjustable thigh support.

The V8 engine: a torrent of power

The Audi S4 Cabriolet's eight-cylinder engine develops 253 kW (344 bhp) at 7000 rpm, and delivers a massive 410 Newton-metres of torque to the crankshaft at 3500 rpm. Such impressive figures are a sure sign of the superiority of this large-capacity, naturally-aspirated engine with its five valves per cylinder. Possibly even more impressive than its peak power output is the immediacy with which it responds to every movement of the accelerator pedal, and its remarkable willingness to run freely up to high revs. The exhaust system produces a deep, sporty note, always present but never obtrusive.

The Audi S4 Cabriolet sprints from 0 to 100 km/h in only 5.9 seconds, and reaches a top speed of 250 km/h, at which point the governor cuts in smoothly.

The eight-cylinder engine surprises the onlooker in yet another way: it is shorter and more compact than any other engine of this type and size, measuring only 464 millimetres from front to back. Audi's engine developers achieved this by moving the chain drive for the camshafts and auxiliaries to the output end of the engine, thus reducing its overall length by 52 mm. The weight is also extremely low for an engine with eight cylinders, at only 195 kilograms. This has definite advantages in terms of the car's weight distribution and road dynamics.

From the six-speed close-ratio gearbox of the latest model generation with a precise shift action and short lever travel, the power is delivered to the 18-inch diameter cast aluminium wheels. The selector mechanism is decoupled, which largely prevents load-reversal movements or vibration from being transmitted to the gear lever inside the car.

Available as an optional extra, the six-speed tiptronic transmission with dynamic shift program, additional Sport programme and shift paddles on the steering wheel it combines sports-style progress with the convenience and relaxed driving of an automatic transmission and is therefore ideal for smooth, relaxed travel in an open car.

The sports suspension: aluminium makes the car agile and light on its feet

The weight-saving aluminium running gear consists of four-link front and trapezoidal-link rear suspension, and is designed to ensure maximum steering precision and clearly defined road behaviour with excellent lateral stability. Ride comfort also benefits from this ingenious suspension design, since low unsprung weight makes the suspension more responsive to road-surface irregularities.

Like the S4 saloon and Avant, the S4 Cabriolet has firm sports suspension settings which are an important precondition for agility and thus for pure driving pleasure.

Servotronic power steering is standard equipment; it varies the degree of power assistance according to road speed so that the correct combination of steering precision and light action is always obtained.

The quattro driveline: driving fun and ample traction

The new Audi S4 Cabriolet has quattro permanent four-wheel drive as a standard feature. It can therefore translate engine power into optimal progress in any conditions and exploit the dynamic potential of its aluminium running gear with a new degree of supremacy. There is no other term for this but "top-class driving pleasure".

Cabriolet: emotions under an open sky

Driving a convertible is definitely one of the most emotionally satisfying forms of automobile transport - particularly in a car with such a timelessly elegant body and wonderfully responsive engine. But elegance and power need to be accompanied by a body of no-compromise high quality before one can be certain that every journey will be pure pleasure.

The soft top of the Audi S4 Cabriolet retracts fully into the body when open. Nothing disturbs the characteristic shoulder line that extends smoothly along the top of the body. But even with the soft top closed, the silhouette retains its dynamic, harmonious effect. The gentle curve of the soft top emphasises the car's low-slung proportions and the mild wedge-shaped outline of the body.

Another typical Audi feature is the outstandingly high quality of the interior materials and workmanship on the Cabriolet. The interior decor is perfectly matched to the body styling and contributes greatly to the overall visual elegance of the Audi S4 Cabriolet.

The body: sets the class standard for freedom from vibration

Even in the early planning stages, Audi's body developers worked systematically on the structure of the body and simulatde its reaction to movements of the suspension and the mechanical assemblies.

The result of this development process is that no unpleasant levels of either high- or low-frequency vibration reach the passenger area on any of the roads commonly encountered anywhere in the world.

Driving pleasure also profits directly from the bodyshell's high rigidity; with its direct steering, the S4 Cabriolet can be steered with great precision through corners, aided by a special steering column mounting that takes the specific pattern vibration in an open-topped body into consideration. The steering column mounting has an additional support, with the module cross-member linked to the cross-beam below the windscreen - measures that are crucial for keeping vibration at the steering wheel down to the lowest possible level.

At an early design stage, when grades of material and joining techniques are decided upon, measures are taken to maximise strength and rigidity. For example, more than half the weight of the body-in-white is accounted for by high-strength or extra-high-strength sheet metal.

Optimised panel thicknesses and improved spot-welding quality have helped to raise the potential operating life of the body structure considerably. In addition, the body has been reinforced by a rigid bolted-on frame at the front with supporting diagonal struts at the front and rear.

A high level of crash protection

The Audi S4 Cabriolet's A-posts are optimised in cross-section and contain high-strength reinforcing tubes - a most important safety feature if the car should roll over.

In the occupant area, the body sills have been optimised in terms of sheet metal gauge and cross-section, to increase their strength and provide optimal protection for the occupants. High-strength tube is also used in the seat structure, so that occupant safety is enhanced in the event of a side-on impact.

The doors in particular have to be designed with safety in mind. In conjunction with structural reinforcements in the sills and a strengthening cross-member below the rear seat, special impact absorbing beams in the doors ensure a high standard of safety. Crash resistance, even in the side impact test against a post, is on the same excellent level as the S4 saloon.

Finally, there is a double bulkhead at the rear that also adds to the strength of the body.

All-round safety

Seat belts with belt force limiters and belt tensioners at all seats are part of the comprehensive safety equipment, as are the full-size front and side airbags. The latter are integrated into the front seats and protect the occupant in the head and thorax areas.

If the car should roll over, an active roll-over protection system in the double rear bulkhead adds to the occupants' safety. Two sensor-controlled protective hoops behind the rear seats are triggered off in a fraction of a second and, together with the extremely rigid windscreen frame, help to maintain an intact 'survival zone' for all the car's occupants.

Active safety is maintained at a high level by the Electronic Stabilisation Program ESP, which is standard equipment and includes an hydraulic brake assist function.

Weather protection and much more - the soft top

Standard equipment on the Audi S4 Cabriolet is an electro-hydraulic soft top, which closes at the touch of a button in under 30 seconds. The button only needs to be pressed once to either open or close the soft top. The side windows move down slightly and up again to aid the process, and in the Audi S4 Cabriolet there is no locking handle to be released manually or tonneau cover to be detached.

A lever in the boot raises or lowers the soft top compartment, so that a much larger luggage space becomes available when the soft top is closed.

A heated, scratchproof glass window is just one of the reasons why the Cabriolet's lined soft top is entirely suitable for winter driving. It has three layers of cloth and is sewn to high standards of accuracy to ensure maximum occupant protection, resist climatic effects and provide a standard of acoustic insulation worthy of a fine car such as this.

The soft top linkage can scarcely be detected from outside the car; the upholstery material is held taut to avoid any 'ballooning' effect. The harmonious outline of the roof that blends so well with the Cabriolet's body is retained when the car is travelling fast.

Inside the car too, the soft top has a completely smooth surface. This is most attractive to the eye, and therefore adds to the luxurious impression created by the interior decor and trim.

New Audi A2 1.4 TDI with 90 bhp engine: A light athlete with a high-tech heart

The Audi A2 1.4 TDI with 55 kW (75 bhp) engine will soon have a big brother: starting in November 2003, an uprated version of the A2 with a 66 kW (90 bhp) engine will join the programme, enlarging it to five engine versions in all. With a maximum torque of 230 Nm between 1900 and 2200 rpm, this compact three-cylinder unit accelerates the A2, a true 'light athlete' with an aluminium body, in 10.9 seconds from 0 to 100 km/h. This new top version in the Audi A2 model line has a top speed of 188 km/h and complies with the tough European EU4 exhaust emission limits.

The customer benefits in two ways: there is a tax concession until 2005, and in any case the car's fuel consumption is gratifyingly low, with a total test figure of only 4.3 litres of diesel per 100 kilometres.

The new engine owes its higher power output and torque primarily to a new turbocharger with variable turbine geometry and a boost pressure raised to 2.3 bar (absolute). The new charge-air intercooler, with a distinctly higher efficiency rating, also contributes to the 1.4-litre engine's higher performance, as does the optimised combustion chamber pattern. The compression ratio has been lowered to 18.0 : 1.

Further detailed work on the engine and its high-pressure fuel injection system has enabled Audi's engineers to comply with the most stringent emission limits currently valid worldwide. Examples of their work are the electrically operated exhaust gas recirculation system, which now has an uprated cooling capacity and the shutoff flap in the intake manifold, controlled by the engine operating map, which helps to maintain the optimum combustion mixture. The pump-injector elements have a modified spray angle and increased flow capacity to suit the new operating situation.

There have been detail modifications to the entire pump-injector system. The new Bosch EDC 15 engine management with EOBD (European On-board Diagnosis) and separate pilot injection has injector elements of even higher precision and therefore exerts a positive effect on emission and noise levels.

The larger oil cooler and the new pistons with cooling oilway are a logical consequence of the more extreme temperatures likely to be encountered in this powerful engine. Screening measures on the intake manifold and cylinder block have achieved a distinct improvement in the three-cylinder engine's acoustic refinement.

This new "high-tech heart" suits the character of the Audi A2 very well. The engine's low weight of only 127 kilograms helps to keep the complete car's unladen weight down to 1,030 kilograms and achieve balanced weight distribution between the axles. The results of this successful combination of features are dynamic road behaviour and a high level of agility.

In view of its high performance and the ability to carry up to five people, the new model's unrivalled fuel economy is all the more impressive. The fuel tank holds 42 litres, so that an action radius of up to 1,000 kilometres is possible before refuelling, which makes the A2 1.4 TDI extremely suitable for journeys involving long distances.

The suspension has also been matched to the increased performance potential, with spring and shock absorber ratings chosen for perfect harmony between agility and convincing ride comfort in all journey conditions. Like the A2 1.6 FSI, this new top TDI model has disc brakes at the rear wheels as well, so that effective stopping power is always available.

When it goes into production before the end of this year, a closer look will be needed to find the red 'I' in the badge on the tailgate that identifies this new and most powerful TDI version of the A2.

The 66 kW A2 1.4 TDI enlarges the Audi A2 programme to five models, all of which comply with the EU4 exhaust emission limits. In addition to the two spark-ignition engines, one of which is the 1.6-litre FSI with direct petrol injection, and the 1.4 TDI with 55 kW (75 bhp) engine, the four-ring emblem is also to be seen on the A2 1.2 TDI, which appeared in 2001 and was the world's first five-door model with a fuel consumption of only three litres per 100 kilometres.

Like all the other versions of the A2, the 1.4 TDI with its uprated engine represents the sum of the experience that Audi has gained as a pioneer of weight-saving design. The Audi Space Frame ASF principle makes the A2's aluminium body more than 40 percent lighter than a similar car of conventional pressed-steel construction, yet it has an interior of generous size that makes excellent use of the available space, so that the occupants travel in conditions of outstanding comfort.

The space floor concept, with the rear footwells lower than those in front, adds to the available space in the rear-seat area and guarantees rear seat occupants an ergonomically correct, relaxed seated position that is not matched by any other car in this class.

As with the Audi A8, the aluminium body built according to the Audi Space Frame ASF principle is the key to high passive safety. The extremely rigid frame structure protects the car's occupants like a cocoon and absorbs impact energy most effectively.

With two front and two side airbags and seat belt tensioners and belt force limiters at all seats, the Audi A2 offers its occupants a high standard of safety. The optional sideguard head airbags set a new standard in this car class.

Since mid-May 2003 the A2 colour.storm has been available, a colourful eye-catcher with the body painted in Misano Red, Imola Yellow or Sprint Blue and with matching seat upholstery fabrics in each case. A visual contrast is provided by various outer surfaces and add-on items with a matt black paint finish, for example the roof, outside mirrors, wheel arches, protective rubbing strips and service module flap.

The Audi A2 1.4 TDI with 66 kW/90 bhp engine will reach the showrooms in September 2003, at a list price of € 19,200.

Audi A3 1.6 FSI

Audi is adding a thrifty sprinter to the range of versions of its compact sports model, the A3: inside its engine compartment, the A3 1.6 FSI has a four-cylinder engine with FSI petrol direct injection, developing 85 kW (115 bhp) and 155 Nm of torque.

It propels the dynamic three-door model up to a top speed of 196 km/h; the speedometer needle hits 100 km/h after 10.9 seconds. But this four-cylinder engine has more than just sports talents to recommend it.

The 1.6-litre FSI engine also demonstrates potential for fuel economy thanks to its petrol direct injection technology. The A3 1.6 FSI consumes just 6.5 litres of Super Plus fuel per 100 kilometres, pushing the figure down to a remarkable 5.3 litres per 100 km in extra-urban conditions.

This is undoubtedly an unbeatably low figure for a petrol engine, considering its performance. The 55-litre fuel tank means that a range of over 850 kilometres is possible without pauses for refuelling.

The FSI engine has another pleasing result of its refined engine technology in store for drivers: since the vehicle is classified in emission category EU4, there is a tax exemption in Germany for new cars registered before 1 January 2005.

This new version, which is going into production in August 2003, extends the Audi A3 range to three 4-cylinder petrol engines - as well as the 1.6, there is a further petrol direct injection model in the guise of the 2.0 FSI. The A3 1.6 FSI with six-speed manual gearbox as standard will cost € 20,100 in Germany.

Motor sport expertise

In technical terms, the new engine for the A3 is closely related to the racing engine that powered the Audi R8 racing cars to victory at the Le Mans 24 Hours in 2001 and 2002.

Here again it was a combination of more power from less fuel that demonstrated Audi's technological lead in a very literal sense. With lower fuel consumption than conventional racing engines, the cars were able to put in an extra lap between refuelling stops.

Fuel injection under high pressure

The term "petrol direct injection" makes the most significant distinction between this and conventional petrol engines clear: in contrast to indirect injection, the fuel is injected directly into the combustion chamber.

The injector, located on the admission side in the cylinder head, is served by a high-pressure pump driven by the camshaft and a pressure reservoir shared by all cylinders - the common rail system. The injector controls the injection time to within thousandths of a second at injection pressures of up to 110 bar. By comparison, indirect injection operates at a maximum of four bar.

There is a further special feature on the admission side - the tumble flap. This can be adjusted to two different positions on the 1.6 FSI engine, thus specifically influencing the movement of the incoming air.

This makes two different operating modes possible, the prerequisite for the versatility of the FSI principle: homogeneous and stratified-charge operation. Depending on the engine speed, load status and accelerator pedal position, the engine electronics always select the optimum mode - without the driver even noticing.

Homogeneous-charge operation at full load

A conventional engine with indirect fuel injection establishes an ignitable air-fuel mixture of a ratio of 14.7:1 (lambda = 1) throughout the entire combustion chamber. An FSI engine also operates in this mode, known as "homogeneous operation": namely whenever the engine is required to produce a high power output.

At full load, the fuel is injected synchronously with the air intake phase. This fills the combustion chamber evenly. By virtue of the precision injection process, the extremely fine atomisation and the internal cooling effect when the fuel vaporises directly inside the combustion chamber, the FSI engine can run at a higher compression ratio than an engine with an indirect injection system. This permits greater efficiency.

Stratification: maximum consumption reduction

The crucial feature of the new engine that paves the way for fuel-saving, however, is stratified-charge operation at partial loads.

In this operating mode, fuel is not injected until the compression phase. It is now injected directly into the air in the combustion chamber, in which a tumbling movement is induced by the diagonal position of the tumble flap and the special shape of the piston crown.

This specific tumbling movement makes it possible to establish the required stratification: precisely at the point of ignition, the cloud of fuel and air which fills only part of the combustion chamber reaches the spark plug, permitting efficient combustion in spite of the excess air in the remainder of the combustion chamber.

Audi A3 3.2 quattro

The sporty top-of-the-range version of the latest Audi model can now be ordered: the A3 3.2 quattro with six-cylinder engine and completely new transmission technology. The combination of the high-torque 3.2-litre engine, which produces 184 kW (250 bhp), and the innovative sports transmission DSG is a particularly clear indication of the potential of the new Audi A3 as a driving machine.

The Audi A3 3.2 quattro completes the sprint from 0 to 100 kilometres per hour in 6.4 seconds, whilst its top speed is gently governed at 250 km/h. This model has an overall fuel consumption of just 9.8 litres per 100 km. These are figures that speak for themselves, even compared with vehicles with a six-speed manual gearbox.

The compact 3.2-litre V6 engine delivers a broad peak-torque range, with a maximum value of 320 Nm between 2500 and 3000 rpm. In conjunction with the ultra-rapid and precise control technology of the new Direct Shift Gearbox DSG, it responds extraordinarily spontaneously to movements of the accelerator pedal.

The revolutionary Direct Shift Gearbox DSG combines all the advantages of a six-speed manual gearbox with the qualities of a modern automatic transmission. The driver thus benefits from enormous agility and driving enjoyment as well as from convenient operation and smooth acceleration with an uninterrupted flow of power.

So how does DSG function? When driving, one gear is engaged. When the next gearshift point is approached, the appropriate gear is pre-selected but its clutch kept disengaged.

The gearshift process opens the clutch of the activated gear and closes the other clutch at the same time with a certain overlap. The gear change consequently takes place under load, with the result that a permanent flow of power is maintained.

Thanks to optimum gearshift strategies, the control technology integrated into the transmission produces instantaneous gearshifts that are nevertheless smooth and virtually jolt-free. And by moving the gear lever in the manual gate or operating the standard-fit shift paddles behind the steering wheel like in a racing car, the driver can actively influence the choice of gears and the gearshift point at any time.

On the Audi A3 3.2 quattro, a hydraulic multi-plate clutch varies the distribution of power between the front and rear wheels. By distributing propulsive power permanently to all four wheels to suit the situation in hand, the drive system guarantees maximum traction and, as a result, optimum acceleration.

At the same time there are still ample reserves for transmitting cornering forces in the interest of cornering safety and directional stability. The arrangement of the engine at the front and the multi-plate clutch at the rear is beneficial to axle-load distribution. Indeed, this weight distribution is crucial to the excellent directional stability and good handling of the A3 3.2 quattro.

A 17-inch dual-piston brake system adapted from the version used on the Audi RS 4 assures the appropriate braking performance; the front discs measure a generous 345 millimetres in diameter. The standard sports suspension is fitted with 17-inch cast aluminium wheels and size 225/45 tyres. This combination not only looks extremely dynamic, but also offers excellent running qualities on both dry and wet roads.

The A3 3.2 with DSG and the Ambition equipment line costs €32,850 in Germany. As an alternative, the A3 3.2 quattro is also available with a six-speed manual gearbox for €31,000. Deliveries of both versions will start this year.

Audi A8 3.0 TDI quattro

Since its debut in the autumn of 2002, the Audi A8's convincing road dynamics, advanced technologies and highly exclusive design and equipment standards have confirmed it as a symbol of sports character in the luxury car segment.

A new V6 TDI engine has now been developed and is being offered as a fifth and once again a particularly sporty engine option for the A8. In the A8 3.0 TDI quattro it develops 171 kW (233 bhp) at 4000 rpm and has a maximum torque of 450 Newton-metres all the way up the engine-speed scale from 1400 to 3250 rpm.

The A8 3.0 TDI quattro remains the first and only diesel car in the large luxury class to be available with a six-speed tiptronic transmission and permanent all-wheel drive, and also to outperform the tough EU4 exhaust emission limits that will not come into force until 2006.

With its turbocharger and mapped-control, cooled exhaust gas recirculation (EGR), the V6 not only differs in engine size and additional power output from the previous 2.5-litre, 132 kW (180 bhp) version. It is also the first six-cylinder TDI from Audi's new family of vee engines, and has the camshafts and oil pump driven by chains.

The new engine also has extremely advanced fuel injection, the first time that the very latest common-rail generation has been used on an Audi V6 TDI. Piezo inline injectors permit up to five separate amounts of fuel to be injected on each working stroke, at an injection pressure of 1600 bar. These devices help to keep emissions to a minimum and achieve an agreeable noise pattern.

In performance terms, the A8 3.0 TDI quattro lies well ahead of competitors' six-cylinder diesels in the large luxury car category.

This lightweight luxury saloon with its aluminium body takes only 7.8 seconds to sprint from a standstill to 100 km/h - a figure unequalled by any V6 diesel saloon on the international market.

It can also reach a top speed of 243 km/h, and its peak torque of 450 Newton-metres provides the driver with abundant pulling power in every road-speed and engine-speed range.

High-tech TDI

Following the 4.2-litre spark-ignition engines used in the S4 and allroad quattro 4.2 models and the 4.0 TDI, also with eight cylinders, the 3.0 TDI is now the fourth member of the new Audi vee-engine family. The V6 TDI engine is also an extremely compact design, with an overall length of only 440 millimetres.

The crankcase of the V6 engine and its two cylinder blocks, which are at a 90-degree included angle, are made from vermicular graphite cast iron, a material with twice the strength of conventional grey cast iron, but weighing some 15 percent less. This is a major step towards reducing the weight of the engine to only 220 kilograms, which makes the 3.0 TDI one of the lightest V6 diesels available anywhere. The power-to-weight ratio and the car's front-to-rear weight distribution - two values that are of key significance for the new A8 3.0 TDI quattro's dynamic performance - both benefit from this low figure.

Compared with the previous engine, both the cylinder bore (now 83.0 mm) and the stroke (now 91.4 mm) have been increased. The total swept volume is now 2967 cc. In the new engine block the cylinders are 90 mm apart, compared with the previous figure of 88 mm. The compression ratio has been reduced from 18.5 to 17.0 : 1.

Four valves per cylinder ensure optimal combustion chamber filling. The new V6 engine's valves are actuated by roller cam followers with hydraulic clearance adjustment. This low-friction valve gear makes a big contribution to the 3.0 TDI's lower fuel consumption and reduced emissions.

The engine's noise pattern also benefits from the use of roller cam followers. Together with the camshaft drive gears, which are tensioned to eliminate as much tooth backlash as possible, mechanical noise from the valve gear is lower, so that the 3.0 TDI proves to be a very smooth, quiet-running engine.

An engine block of extremely rigid design and an effective engine enclosure also help to keep the six-cylinder engine's noise emissions down to a very restrained level. A further extremely significant contribution to this exceptional engine refinement is made by the smooth combustion process, with optimised pilot injection from the latest generation of common-rail fuel injection systems.

Common rail technology with piezo inline injectors

Fuel is supplied to the combustion chambers by the latest generation of common rail fuel injection, the Bosch CRIP II+. This has a high-pressure pump and a separate distributor rail for each bank of cylinders. The maximum injection pressure is now 1600 bar, 250 bar higher than on earlier common-rail systems, and a value that can best be visualised as the weight of a complete midsize car pressing down on the area of a fingernail.

This high injection pressure atomises the fuel still more effectively, so that the resulting mixture is more satisfactory and burns efficiently in the combustion chambers. Not only additional power and torque result, but also lower fuel consumption and emissions.

The most important innovation in this new common-rail system are undoubtedly the piezo injectors. To utilise the so-called 'piezo effect' for fuel injection, an electrical charge is applied to a ceramic element and causes its crystalline structure to change. The resulting very slight change in its geometry, supported by a hydraulic device, opens the injector needle mechanically.

Piezo injectors have a number of advantages compared with the conventional solenoid valve. The moving mass at the injector needle is cut by 75 percent, for example, and weighs only four instead of the previous sixteen grams. This makes it possible to deliver even smaller amounts of fuel accurately, and also increases the speed of injector needle movement. This is now 1.3 metres per second, which means that the piezo injectors react twice as fast as those used in other common-rail injection systems.

As a result, the number of injection strokes on each working cycle of the engine can be varied almost without restriction. For the 3.0 V6, the Audi TDI development team decided to inject fuel at four successive points: at low engine speeds there is a double pilot-injection stroke as well as the main injection stroke; at moderate engine speed a single pilot injection stroke is used. At about 2500 rpm and high part-load, a single post-injection stroke is also performed.

This strategy cuts emissions as well as making the combustion process smoother, so that engine noise levels are reduced. The 3.0 TDI engine is not only significantly quieter and smoother than its forerunner, but in fact undoubtedly sets the benchmark in this area for all other engines in its class.

Fuel is injected into the combustion chambers through seven-hole injector nozzles. These too help to distribute the fuel uniformly, achieve particularly efficient combustion and therefore reduce undesirable exhaust emissions.

Quality that satisfies even the toughest standards: the new Audi A8 3.0 TDI quattro, in contract to its competitors, has permanent all-wheel drive and a six-speed tiptronic transmission as standard equipment. Thanks to its admirably low untreated emissions, it nevertheless remains well below the EU4 emission limits, which will not become law until 2006.

Engine management on the V6 TDI is in the hands of the Bosch EDC16 system, which regulates fuel volume, the start of the injection stroke, the turbocharger's boost pressure and the degree of exhaust gas recirculation.

As on the A8 with spark-ignition engine, this electronic system makes it possible to start the engine automatically at the touch of a button. The rapid pre-heat system with its ceramic glow plugs brings the 3.0 TDI to life without delay even at very low winter temperatures, in other words without the irritating waiting period typical of diesel engines in the past.

Turbocharger and two charge-air intercoolers

To ensure the best possible cylinder charge in all operating situations, the 3.0 TDI six-cylinder engine has a turbocharger neatly installed in the vee between the cylinder blocks in order to save space. For maximum efficiency the intake air temperature is lowered effectively and with minimum pressure loss by two charge-air intercoolers operating in parallel. They are located behind the inlet apertures in the front apron and therefore directly exposed to the airstream when the car is in motion.

The turbocharger on the new 3.0 TDI engine has variable turbine geometry with an electric adjuster. This alters the angle of the turbine blades more quickly and accurately, so that boost pressure builds up with a minimum delay at low engine speeds in particular and the engine's response to accelerator pedal movement is improved. Blades of optimised shape on the impeller and turbine wheels make a further contribution to efficiency, with the result that this engine does not suffer from unpleasant 'turbo lag'.

Continuously variable swirl flaps are incorporated into the intake manifold. They enable the airflow to be adjusted to suit engine speed and load. A greater degree of swirl at low loads optimises the combustion process, whereas at high engine loads the best results are obtained with minimum swirl. Closing an inlet port at low load achieves the required increase in swirl, but the ports are opened at higher loads to ensure good cylinder filling.

Effective exhaust emission control

The exhaust manifolds are double-walled with an air gap in between, to ensure that the exhaust gas reaches the turbocharger and the catalytic converters that follow without significant heat loss. Effective cooling, on the other hand, is needed for the exhaust gas recirculation system, and is particularly important if emissions of oxides of nitrogen (NOx) and particulates are to be reduced effectively.

The exhaust gas diverted through the recirculation system passes according to temperature and engine load through a water-filled cooler located in the vee of the engine, where it also takes up no unnecessary space. A bypass line avoids passing the exhaust through the cooler while the engine is still cold, so that hot exhaust gas reaches the catalytic converter sooner and causes it to light off. Once the engine is warm, the exhaust gas begins to flow through the EGR cooling system.

Exhaust emission control is by means of a pre-converter located close to the engine and the turbocharger, and the main catalytic converter under the floor pan. All this equipment has the effect of keeping exhaust emissions from the A8 3.0 TDI well below the EU4 limits - a first in the luxury diesel category.

Lower fuel consumption

At least as welcome as the new engine's efficiency in reducing exhaust emissions is its economical use of fuel. Despite its higher power output and torque, its fuel consumption has remained at the previous low level.

The average figure according to the standard fuel consumption test is 8.9 litres of diesel oil per 100 kilometres. This is at the same favourable level as the previous A8 2.5 TDI quattro, despite an engine that develops 53 bhp more and the higher overall weight. A welcome spin-off is that new A8 3.0 TDI quattro can now cover a distance of more than a thousand kilometres before refuelling - a value that clearly reveals how perfect this sporty TDI luxury saloon is for long-distance travel.

A8 3.0 TDI quattro: supreme sports character in the luxury segment

The new six-speed tiptronic transmission with its dynamic shift program DSP and additional Sport program is available for the first time with a V6 TDI engine. Thanks to the additional forward ratio, power output and torque can always be controlled in such a way that no conflict arises between a spontaneous flow of power, high performance on the road and perfect refinement.

At the same time the additional sixth gear ratio increases the overall spread between the lowest and highest gears, a decisive factor for greater dynamism on the one hand and optimal fuel economy on the other.

Gears can also be selected manually, either by moving the selector lever to the tiptronic section of the gate or by using the 'paddles' behind the steering wheel, an ergonomically perfect solution that has already proved its worth in the Audi R8 Le Mans-winning cars. The driver can for instance change gear while the car is being cornered, without having to move a hand away from the steering wheel.

permanent all-wheel driveline still sets the standards in the luxury car segment. It converts the maximum amount of engine power into traction at the wheels and enhances lateral location of the vehicle; even the very considerable torque that this engine delivers can be transmitted effortlessly and safely.

The aluminium body - the lightweight way to the top

The innovative aluminium body, which uses the latest version of the Audi Space Frame ASF principle, is the immensely strong basis that acts as a key to weight saving, sporty performance and outstanding road behaviour. Compared with the first-generation A8, more large functional castings and extruded sections have been incorporated into the completely closed ASF, with the result that the total number of elements in the structure is now much lower. Static torsional rigidity is 60 percent higher and has led to a worthwhile reduction in vibration and an increase in safety and dynamic potential. The weight of the body-in-white is some 50 percent lower than a comparable pressed-steel body, which means minimum mass allied to maximum strength.

The suspension: even more dynamic if the driver wishes

The new Audi A8 has an evolved version of the previous aluminium suspension, with a four-link layout at the front and self-tracking trapezoidal-link rear suspension. The brake system has also been redesigned, and the steering, with variable ratio and servotronic power assistance, is also new.

The adaptive air suspension - a '4-corner' system with continuously variable shock absorber settings, succeeds in resolving the classic conflict of objectives between good handling and a standard of ride comfort worthy of this class of car. In every driving situation, adaptive air suspension selects the most suitable suspension characteristics, modifies the damping action to reduce body movement and optimises road holding and ride quality.

Data from four sensors at the wheels and three acceleration sensors on the body are evaluated by the adaptive air suspension's central control unit. This defines the driving situation and within a few thousandths of a second computes the necessary adjustment signals that are transmitted to the individual shock absorbers, with the aim of maintaining optimal road dynamics and ride comfort at all times.

The driver can also choose between four pre-defined settings extending from a clear sporty emphasis to the highest level of ride comfort, and ensuring that no wish is left unfulfilled.

The MMI control concept: maintaining choice, reducing complexity

Audi's MMI integral user interface for the A8 is an infotainment platform and a control concept that uses strictly logical principles to make it easy to use. For the driver, MMI consists first and foremost of the user controls (the MMI terminal) in the centre console, with a control knob that can be turned and pressed in and four control keys grouped around it.

At the sides of the terminal there are altogether eight function keys that can be used to select the most important main menus directly. There is also a return key to revert to the previous menu level. Above the centre console, is the second central MMI unit, a 7-inch format colour screen that can be retracted into the fascia but, when raised, is ideally positioned in the driver's field of view.

The basic layout of the screen display corresponds in its details with the positions of the control keys and control knob on the MMI terminal. This creates an intuitive link between what can be seen and the hand movements that have to be performed. The more often a function is selected by the driver, the higher it rises in the menu structure so that it can be reached easily and quickly.

Sporty six-cylinder - Audi A8 3.0 V6

Audi has added a fourth engine option to its sporty A8 luxury saloon programme. The six-cylinder 3.0-litre engine is available immediately with front-wheel drive and, a unique offer in the large luxury car segment, with multitronic continuously variable transmission. Thanks to its lightweight aluminium body, the 162 kW (220 bhp) V6 engine is able to accelerate the A8 from a standing start to 100 km/h in only 7.9 seconds, and take it on to a top speed of 242 km/h. Another new departure is that this new power train is available for both standard and long-wheelbase versions of the A8.

The first A8 model family was already available with a smooth-running, powerful V6 engine. Thanks to systematic weight-saving design, even that version, although equipped with the smallest spark-ignition engine in the range, nonetheless performed in a manner worthy of a large luxury-class car. When it came to fuel consumption, however, the 174 bhp, 2.8-litre V6 was content to consume only about as much fuel as a typical midsize car.

These outstanding qualities are not only still present but have been given an even sharper profile for the new Audi A8 3.0. The aluminium V6 engine, with five valves per cylinder, has a swept volume of 2976 cc and from it develops the impressive power output of 162 kW (220 bhp) at 6300 rpm. Maximum torque is 300 Newton-metres and is available at 3200 rpm. Once again, Audi has succeeded in creating a high-performance engine with an extremely moderate thirst for fuel. The average consumption of the A8 3.0 multitronic with front-wheel drive is only 9.6 litres of super-grade fuel per 100 kilometres.

The supremacy of this engine is also expressed by its sporty sound, which has been carefully tuned by the design team. The engine-compartment design too is clear confirmation of the high technical standards that these Audi engines represent.

Two multi-stage catalytic converters with metal monoliths are located close to the engine for efficient exhaust emission control. As a result, the 3.0 V6 engine installed in all versions of the A8 complies with the tough EU4 exhaust emission limits.

The multitronic continuously variable automatic transmission makes the optimal use of engine power and potential for fuel economy that have until now only been available with a manual-shift gearbox, yet it also offers the same degree of convenience as a classic automatic transmission with torque converter. And since the gear ratio varies steplessly, the A8 3.0 cannot suffer from jerky gear shifts.

Adaptive air suspension - air springs and shock absorbers with adaptive settings - as well as the innovative MMI operating concept are of course standard features of all 3.0 versions of the Audi A8.

The German-market list price of the A8 3.0 multitronic with front-wheel drive is € 59,800; the long-wheelbase version starts at € 66,200. This model can be ordered immediately; the first cars will probably reach German customers before the end of the third quarter of 2003.

The new Audi navigation system plus - Freedom for individual mobility

The new Audi radio navigation system plus will be added to the A3's optional extras programme early in 2004. Its DVD drive not only permits almost complete navigation on Western European roads, but also plays audio and MP3 CDs. The controls use the same clear logic as the Audi MMI already familiar from the A8. The integral double FM tuner ensures optimal radio reception, a convenient choice of stations and provision for dynamic navigation, using the TMC Traffic Message Channel even while listening to a different programme.

The speech-output route recommendations have been considerably extended and are now even more detailed. Together with the clear pictograms for visual route information on the central driver information system display, they form the highly praised basis for the Audi satellite navigation system first introduced in 1996.

The entire control concept is new, and uses the same consistent logic as the Audi MMI in the new Audi A8, to guarantee rapid, easy access. The system's many new functions and possible settings can be selected intuitively in a user-friendly way. This reduces the risk of being distracted during the journey, avoids adding to the driver's workload and enables him or her to concentrate as much as possible on the primary task of driving the car safely. A further advantage is that the driver does not have to study a lengthy set of operating instructions before being able to make use of all the systems's varied functions.

The control panel, with the typical square MMI layout, is located to the right of the display screen. With its four control buttons and central control knob, it parallels the display that is actually seen on the screen. Farther down but equally easy to reach, the large 'Return' button displays the previous menu level when pressed. Eight well-placed function keys below the screen provide direct access to the principal functions.

The 6.5-inch colour screen displays the road map and the visual route description; the driver information system converts this information into pictograms and combines it with further distance and time-of-arrival information.

The high-quality image on the large screen resembles a conventional road map: it not only shows the name of the road or street on which the car is currently being driven, but also the names of adjacent roads, towns and villages. If preferred, the new system can show the map in perspective, as a 'bird's eye view'.

The split-screen function is also new. It enables the map to be seen on the left half of the screen, with the right half devoted to useful additional information. For example, the realistic or schematic pattern of roads at a motorway junction, or - particularly important in city traffic - an enlarged view of the route the car is actually following. In addition, the system supplies information on the next three route recommendations, to make it easier to choose the correct traffic lane. The automatic multi-stage 'manoeuvre zoom' also supplies the driver with precise, detailed information.

The new Audi navigation system plus offers the driver a selection of up to three different routes. The control knob can be used to select a short route, a fast route or an alternative route. These recommendations take traffic information messages, route length and estimated time of arrival into account. In addition to the final destination, up to three locations through which the route should pass can be chosen. Traffic messages received by the twin tuner are displayed, automatically evaluated and taken into account when a route is recommended, with an alternative route being worked out if necessary. In addition, by pressing a button the TMC messages can be shown directly on the map in text form.

Other convenient functions are full scope for direct destination input from the map display by means of the cursor, address input starting with the street, use of the address book and even the input of destinations as telephone numbers or post codes.

In addition to the time of arrival at the chosen destination, the new navigation system plus can also display special destinations on motorways when the split-screen mode is in use, for example filling stations, leisure areas or parking lots on the next section of the route. In addition to the distance, the driver is also informed of the calculated time to reach these intermediate destinations.

As the new data storage element for the navigation system, DVD has a memory ten times larger than the conventional CD-ROM, and distinctly faster access times. Almost the entire Western European road network can be accommodated on a single DVD disc, so that irritation of having to change the CD when crossing a national border is avoided. Another bonus is that routes are calculated very much faster than with CD-based sysems. This will be seen when the map image is built up, and also when the zoom function is used.

The DVD is also capable of memorising many more special navigation destinations (points of interest). Locating a destination is therefore more convenient and quicker if the street name is not known. Among the generous range of special destinations in the new Audi navigation system plus are airports, parking lots, exhibition and event centres, museums, theatres, cinemas and shopping centres.

Behind the flat screen, which folds away electro-mechanically, are the DVD drive and two additional memorised memory card readers (MMC or SD format) with MP3 compatibility. Having these located directly at the system makes it easier and quicker to change from one data and music source to another.

The new Audi navigation system plus supports Audi mobile phone preparation and the facilities provided on the multifunctional steering wheel, which is an optional extra. If required, the system can be upgraded by adding a CD changer, the BOSE sound system or an analog TV tuner.

Audi A2

Numerous awards in several nations provide confirmation of an intelligent concept. The A2 systematically exploits the experience of AUDI AG as a pioneer of lightweight construction. As a result of its Audi Space Frame ASF, the aluminium body of the A2 is more than 40 percent lighter than if it had been made using conventional steel techniques. This means that it weighs around 150 kg less than what vehicles of this size still usually weigh today. The Audi A2 is sporty, agile and particularly economical as a result.

The progressive shape of the A2 signals its character as an innovative vehicle concept through which Audi demonstrates its credentials as a technological trendsetter.

Space floor concept for optimum use of space

The Audi A2, which has a total length of 3.83 metres and is 1.67 metres wide, occupies only minimal road space. Yet there is a generous feeling of space inside this 1.55-metre-high five-door vehicle. The space floor concept with its deeper rear footwells enables passengers to sit in an ergonomically relaxed position.

In addition, the interior is remarkable for its high variability. The rear seats of the A2, the standard version of which seats four, can be folded down individually or together, in two stages. They can also be removed individually if not needed. A three-person, fully folding rear seat bench with three head restraints is available as a no-cost option.

Unmistakeable: the service module

The Audi A2 is the first production car to have a service module: the oil dipstick and filler caps for engine oil and washer fluid are located behind a flap, for maximum convenience. The service module permits easy checking of fluid levels at the service station. The A2 therefore also sets new standards for ease of servicing - the engine hood only has to be opened at the workshop when the car goes in for servicing.

Agile handling with high safety reserves

The suspension of the Audi A2 combines the proven technology of McPherson spring struts at the front and a torsion-beam rear axle with ultramodern electronic components. The Electronic Stabilisation Program ESP is standard equipment, and complements the functions of the Anti-lock Braking System ABS with Electronic Brake-force Distribution EBD and Anti-Slip Regulation ASR.

The Audi A2 engines

The most powerful member of this model series is the Audi A2 1.6 FSI. It is powered by a 1.6-litre petrol engine with FSI petrol direct injection and an output of 81 kW (110 bhp). Thanks to the Audi Space Frame and an aluminium body, the A2 1.6 FSI weighs in at a mere 995 kg. The sportiest A2 is thus capable of accelerating from 0 to 100 km/h in just 9.8 seconds, and clocks up a top speed of 202 km/h.

However, the four-cylinder unit is impressive not for its sporting talents alone. The 1.6-litre FSI engine also demonstrates remarkable potential for fuel economy thanks to its petrol direct injection technology. The A2 1.6 FSI covers 100 kilometres on just 5.9 litres of Super Plus petrol (according to 1999/100/EC) and, like the 1.4-litre engines, complies with EU 4.

The Audi A2 is also full of temperament with the 1.4-litre petrol engine, which develops 55 kW (75 bhp). This four-cylinder engine has multi-point fuel injection. It accelerates the Audi A2 to 100 km/h in 12.3 seconds and on to a top speed of 173 km/h, while consuming just 5.9 litres of Super fuel per 100 km.

The A2 1.4 TDI has a 1.4-litre diesel engine with direct injection using the pump-injector principle. With this swept volume, the three-cylinder diesel is the ideal concept for minimum fuel consumption and emissions. The Audi A2 1.4 TDI's fuel consumption of 4.3 litres per 100 kilometres is that of a small car.

Its performance, however, would do any fully-fledged automobile proud: a top speed of 173 km/h, acceleration from 0 to 100 km/h in 12.6 seconds. The A2 1.4 TDI can cover almost 1000 kilometres on just one 42-litre tank of fuel.

Both the Audi A2 1.4-litre petrol version and the 1.4 TDI satisfy the European EU 4 emission limits, currently the most stringent regulation. This also helps to save its owner a considerable sum of money in vehicle taxation in the long term.

Audi A2 1.2 TDI, the three-litre Audi

The Audi A2 1.2 TDI consumes just 3.0 litres of diesel per 100 kilometres making it the world's first five-door "three-litre" car. This model's sensational drag coefficient of Cd = 0.25 is the lowest of any production passenger car.

TDI - pure, unadulterated economy

Another major contributing factor resulting in the outstanding fuel economy of the three-litre A2 is its ultra-efficient direct-injection turbodiesel engine. The 1.2-litre three-cylinder unit, which delivers 61 bhp at 4000 rpm, not only has a light-alloy cylinder head, but also an aluminium engine block. Weighing around just 100 kilograms, it is one of the lightest car diesel engines around.

The three pump-injector elements (one per combustion chamber) are located in the cylinder head and are driven directly by the camshaft. This technical principle does not need pressure lines, so extremely high injection pressures of up to 2050 bar are possible. High pressure results in even better efficiency thanks to ultra-fine atomisation of the fuel, its optimum combustion and low emissions. The 1.2-litre TDI's peak torque of 140 Nm is produced at between just 1800 and 2400 rpm.

Almost 80 percent of the maximum propulsive power is available at just above idle speed, from 1300 rpm upwards - an excellent basis for high agility and low fuel consumption.

The car's performance leaves virtually nothing to be desired in everyday driving situations: it sprints from 0 to 100 km/h in 14.9 seconds and touches a top speed of 168 km/h. A cruising range of over 700 kilometres is possible with the 21-litre tank. The 34-litre fuel tank available as a no-cost option increases this to 1100 km.

Intelligent power transmission

The intelligent electrohydraulic system of the automatically controlled manual gearbox means that a clutch pedal is no longer necessary. There are three gearshift modes to choose from: manual gear selection by tiptronic and two modes in which gear changes are fully automatic - the conventional mode and an "Eco" mode.

The "Eco" mode comprises a consumption-optimised gearshift program and a start/stop function. This shuts off the engine if the Audi A2 1.2 TDI is stationary for longer than four seconds. As soon as the brake pedal is released, the engine cuts in again fully automatically and instantly. If the driver releases the throttle while on the move, the electronics disengage the clutch and the car freewheels along. When the driver presses the accelerator, the clutch is automatically engaged again once the engine has reached the necessary speed. The clutch is also engaged when the brakes are applied, for instance when driving downhill, so that the engine's braking effect can be utilised.

High standards of safety

On all A2 models, the ASF construction not only ensures a lower body weight, but also a particularly high standard of passive safety. This high-strength frame structure protects the occupants like a cocoon and impact energy is reduced particularly effectively. With two airbags at both the front and sides, seat belt tensioners and belt-force limiters for all seats, the Audi A2 offers its occupants a high level of safety. Optional Audi sideguard head airbags cushion the side window areas, including the A and B-posts. They provide additional protection for the head and neck of the occupants of the outer seats in side or angled impacts.

Equipment: lifestyle, functionality and luxury

The colour.storm equipment package gives the Audi A2 a particularly fresh and exclusive look. In conjunction with new design elements, even greater emphasis has been placed on the sporty, urban character of the Audi A2 - as a lightweight, dynamic and intelligent lifestyle car that appeals to a younger clientele.

The striking exterior colours Misano Red, pearl effect, Sprint Blue, pearl effect and Imola Yellow contrast with the matt black lacquer exterior trim including the roof, exterior mirrors, wheel arches, side rubbing strips, the flap of the service module and the protective strips in the bumpers. The customer can choose between seat fabrics in black-red, black-yellow and black-blue to match the body colour. Colour.storm is available in combination with all engine versions except the 1.2 TDI.

Together with the other equipment packages - Style, Advance, High Tech and S line - every customer can configure their ideal A2.

The Audi A3

Dynamism, design and exclusivity: the second generation of the Audi A3, the premium sports hatchback in the compact class, is even sharper than its predecessor. With powerful four and six-cylinder engines developing up to 184 kW (250 bhp), quattro drive, the new Direct Shift Gearbox DSG (depending on version) and highly dynamic running gear, it offers all the driving pleasure suggested by the sporty lines of its body.

The equipment and materials used once again reach the exclusive standard in the compact class that is also typical of the larger models in the Audi range.

Exterior styling: taut and athletic

The side profile is distinguished by two contours that reveal the new Audi formal idiom: an accentuated shoulder line and the dynamic line. The latter runs above the sill between the wheel arches and emphasises the car's sporty appearance. With their powerful contours, the round wheel arches appear to be resting on the foundations of the sill area, which stands out from the dynamic line.

Large 16- and 17-inch wheels underline the impression of masculine athleticism and make the dynamic potential of the new Audi A3 clearly visible even when stationary. The shoulder line emphasises the plasticity of the side section just as clearly, encompassing the upper horizontal section of the headlights, incorporating the top of the front wheel arch and sloping gently towards the rear before tapering out in an almost straight line on the wide C-pillar.

At the same time, the angle opened up discreetly to the rear between the dynamic line and the shoulder line accentuates the gentle wedge shape of the car's taut, athletic silhouette. This impression is further enhanced by the gently rising baseline of the windows, together with the coupé-like curve of the roofline. The visual centre of gravity of the new A3 is thus to be found at its muscular-looking rear end, creating the impression that the entire car is about to leap forward.

The radiator grille has undergone a further evolution: the top and bottom segments are connected visually by two indented frame lines in the bumper. This single frame enhances the plasticity and thus also the presence of the front end.

With the number of lines significantly reduced and the individual surfaces split up graphically, the rear-end styling is noted for its explicit clarity. One striking feature clearly representing the dynamic character of the car are the visible tailpipes extending out of the single or double-chamber exhaust system, depending on the car's engine.

The interior

The interior styling of the new Audi A3 is distinguished by two features: sportiness and elegance. This impression is created by the low seat position, the high and wide centre console and the clear, generous subdivision of the dashboard. Aesthetically appealing surfaces, quality materials and an excellent finish define a new top standard.

The interior is noted for its combination of ergonomically refined styling and outstanding aesthetic qualities: typical examples include the clear design of the dials and the round air vents with their tasteful aluminium-look surrounds. The easy-grip rotary controls for the automatic air conditioning as well as the door and glove box handles are also trimmed in aluminium.

Two slender bars connect the centre tunnel with the vertical plane of the console, creating an impression of particular lightness. And it is no coincidence that this feature is reminiscent of a genuine icon in modern automotive design, the Audi TT.

Three equipment lines

The new Audi A3 continues its predecessor's successful equipment line concept. Customers can choose from three coordinated lines: the charismatic Attraction version, the particularly sporty Ambition line and the exclusive Ambiente variant.

Apart from the wheels and functional differences, these lines also differ in terms of colours, upholstery materials, steering wheels and inlays.

It goes without saying that safety features such as the Electronic Stabilisation Program ESP, the new front seats with active head restraints and the sideguard head airbag system are a part of the new A3.

Lots of extra space

A significant increase in space for all occupants bears clear testimony to the substantial progress offered by the new generation of the A3. The wheelbase extended by 65 millimetres serves to increase interior length by almost the same figure (+ 55 millimetres). And the greater width of the car (+30 millimetres) ensures a significant improvement in interior comfort.

Compared with the previous model, the rear passengers in particular benefit from considerably more knee room (+29 millimetres). And both rows of seats enjoy significantly more shoulder room (rear +23, front +42 millimetres). Thanks to the low position of the seats that is reminiscent of a sports car, headroom remains virtually unchanged despite the reduction in overall height.

The optional, folding centre armrest at the rear housing two cupholders and a storage box offers particular versatility and practical benefits. When folded down, it also provides a through-loading aperture complete with a removable transport bag for up to four pairs of skis or two snowboards.

The luggage compartment of the new Audi A3 adapts to suit requirements, providing a capacity of 350 litres with the rear-seat backrest in place and up to 1100 litres with the backrest folded down.

Drivetrain

Sporty and clean - an apt description of the range of engines and transmissions for the Audi A3. All engines comply with the EU 4 emission standard which means a major tax benefit for owners with cars registered in Germany.

Depending on engine version, customers can choose between a five-speed or six-speed manual gearbox, a six-speed tiptronic and - for the most powerful petrol and TDI versions - the Direct Shift Gearbox DSG.

This pioneering form of power transmission - inspired by motor racing technology - permits lightning-fast gear changes without any interruption to the flow of power from the engine thanks to its electro-hydraulic twin clutch, and thus sheer driving pleasure in true sports car style.

quattro permanent four-wheel drive remains unparalleled in the premium compact class, serving to translate the performance of the most powerful versions of the A3 into supreme driving force on the road. Audi quattro drive therefore provides the basis for outstanding dynamic handling and active driving safety.

The petrol engines

1.6-litre four-cylinder engine

A familiar sight in the Audi A3 is the 1.6-litre four-cylinder engine with aluminium block, variable intake manifold and overhead camshaft. The cylinder head with valves operated by roller cam followers keeps internal friction extremely low. The new Audi A3 1.6 with 5-speed manual gearbox consumes just 7.0 litres of Super grade fuel per 100 kilometres (overall).

Thanks to its engine output of 75 kW (102 bhp) and a torque of 148 Nm, it accelerates to 100 km/h in 11.9 seconds and reaches a top speed of 185 km/h. A spontaneous engine response and discreet noise level speak in favour of this entry-level model.

2.0 FSI four-cylinder engine

The new two-litre engine offered for the A3 is one of Audi's most sophisticated power units. The crankcase and basic engine dimensions are exactly the same as on the 96 kW (130 bhp) aluminium power unit already featured in the A4 and A6. The big difference, however, is that the FSI engine comes with direct petrol injection incorporating a common rail injection system and a single-piston high-pressure injection pump.

The cylinder head is a completely new development. The four valves per cylinder are actuated by low-friction roller cam followers. The intake camshaft can be continuously adjusted.

The 2.0 FSI in the A3 develops 110 kW (150 bhp) and a maximum torque of 200 Nm at just 3500 rpm. With this kind of power, the A3 2.0 FSI with six-speed manual gearbox accelerates from 0-100 km/h in just 9.1 seconds and has a top speed of 211 km/h.

But alongside its dynamism, an FSI engine is noted equally for its outstanding efficiency: it has an overall fuel consumption of just 6.9 litres of Super Plus per 100 km.

Thanks to a variable intake manifold and dual-branch front pipe, its torque curve sets new standards in this class. This progress has been made possible by the new air-guided combustion process of the 2.0 FSI engine. It allows stratified and homogeneous lean operation with excess air at part load. Continuously adjustable flaps in each intake port together with the special shape of the piston crown ensure the optimum charge movement in the combustion chamber.

During stratified-charge operation, the FSI engine's most economical mode, fuel is not injected until the compression phase, and is then transported to the spark plug by the air turbulence produced in the combustion chamber.

This causes an ignitable mixture to form around the spark plug, with a substantial air surplus in the rest of the combustion chamber. At full load and at high part loads, the FSI engine also operates in the homogeneous mode.

The 3.2-litre V6

The 3.2-litre V6 engine with four valves per cylinder is the crowning highlight of the sportiest A3 ever. With a supreme development of torque and power, it delivers 184 kW (250 bhp) and a broad peak-torque range with a maximum value of 320 Nm from 2500 to 3000 rpm.

Clearly, this is just perfect for powerful pulling force at all speeds as well as fast, nimble acceleration - regardless of whether the driver opts for a six-speed manual gearbox or the new, sporty Direct Shift Gearbox DSG. The legendary quattro permanent four-wheel drive is obligatory.

The performance figures of the A3 3.2 quattro are correspondingly impressive: it accelerates from 0-100 km/h in just 6.5 seconds and reaches a top speed of 250 km/h (governed).

With its cylinder angle of 15 degrees, the V6 is extremely compact - a basic requirement for installation transversely to the direction of travel. The valve control process generates only little friction thanks to the use of roller cam followers with hydraulic adjustment. In order to reduce emissions and further improve efficiency, the inlet and exhaust camshafts are continuously adjustable.

Throttle valve actuation is designed for an exceptionally agile, spontaneous engine response to accelerator pedal movements. Indeed, particularly the interaction of the engine with ultra-fast and precise DSG control provides an entirely new feeling of power and performance on the road. The close connection between throttle and transmission control is made particularly apparent by active throttle blips during downshifts in the selector lever position S and in the manual gate.

TDI engines

The 1.9-litre TDI

One of Audi's most successful engines is also to be found in the A3: the four-cylinder 1.9-litre TDI with pump-injector direct injection. This system produces what is currently the highest injection pressure around: up to 2050 bar. The current version delivers 77 kW (105 bhp), with a mighty torque of no less than 250 Nm at just 1900 rpm.

The A3 1.9 TDI takes 11.4 seconds to accelerate to 100 km/h. And with a top speed of 187 km/h, the entry-level TDI model is ideal for long stretches on the motorway at high average speeds. It consumes 4.9 litres of diesel per 100 kilometres.

The new 2.0 TDI

The first TDI with four-valve cylinder head delivers 103 kW (140 bhp) and reaches its peak torque of 320 Nm between 1750 and 2500 rpm. This results in a supreme performance: the 2.0 TDI reaches a speed of 100 km/h in just 9.5 seconds and continues briskly on up to a top speed of 207 km/h.

Two other fortes of the new 2.0 TDI four-cylinder are low fuel consumption - 5.5 litres of diesel fuel per100 km - as well as compliance with the EU 4 emission standard.

The new Direct Shift Gearbox DSG

The revolutionary Direct-Shift Gearbox DSG combines the advantages of a conventional six-speed manual gearbox with the qualities of a modern automatic transmission. The driver benefits from enormous agility and driving enjoyment with acceleration that is as harmonious as it is dynamic, without any interruption in the power flow. This is combined with good economy thanks to low fuel consumption, and convenient operation.

The basis for this new development is a three-shaft six-speed manual gearbox which offers considerable variability in the selection of the transmission ratio. Thanks to the use of a twin multi-plate clutch with ingenious electro-hydraulic control, two gears can be engaged at the same time.

The gearshifts it produces feel spontaneous and decisive, as if executed at the push of a button. The electronically controlled throttle blip in the manual and S modes reinforces the impression of ultra-dynamic gearshifts. When the next gearshift point is approached, the appropriate gear is pre-selected but its clutch kept disengaged. The gearshift process opens the clutch of the activated gear and closes the other clutch at the same time with a certain overlap. The gear change consequently takes place under load, with the result that a permanent flow of power is maintained.

In the automatic mode, the driver can shift to the ultra-sporty S program in which upshifts are retarded, downshifts advanced and the shifting process accelerated further. A one-touch function accessed via the shift paddles on the steering wheel in addition temporarily calls up the manual mode, even in automatic modes D and S.

New six-speed tiptronic

Moving up a gear: the use of a six-speed automatic transmission is new in the premium compact segment, giving the driver a significant advantage over five-speed versions since the greater overall spread of gear ratios benefits the car's fuel economy.

But that is not all: apart from lower engine speeds in sixth gear, the car's spontaneous punch and agile drive-off performance are also enhanced. A 20 kilogram reduction in weight compared with the five-speed predecessor helps to improve the power-to-weight ratio and weight distribution.

The tiptronic transmission is masterminded by an electrohydraulic control unit with an electronic "brain". The gearshift strategy and torque converter are specifically designed for combined use with the 2.0 FSI engine, with which the new six-speed tiptronic is making its debut in the A3. Dynamic suspension

A highly sophisticated suspension design provides the second foundation for the excellent driving dynamics of the new Audi A3: the further improved McPherson front suspension and the new four-link independent rear suspension. The potential of the brake system with larger disc diameter and 16 or 17-inch wheels (standard on Ambition models) are in keeping with the high performance of the engines.

Electromechanical steering with the amount of power assistance dependent on road speed is a new feature on the A3. It combines optimum feedback from steering movements with a low level of sensitivity to road impacts, and also consumes much less energy than a conventional power steering system. This servotronic has active return assistance and automatic straight-ahead correction.

The rear suspension

In favour of an even more pronounced sporting performance, the engineers developing the A3 designed a compact, light four-link rear axle. The functional separation of longitudinal and lateral forces provides a high level of lateral rigidity in the interest of optimum dynamism and driving safety and, at the same time, makes the suspension extremely soft lengthwise for improved ride comfort.

On each side the axle construction incorporates a wheel carrier with a wheel bearing unit, two lower wishbones (spring link and tie rod), one upper wishbone and a trailing arm.

The three wishbones are connected to the car body by a subframe. This structure on the front-wheel-drive A3 is made of high-strength steel tubes and plates and is bolted firmly to the body, forming a complete unit that helps to save weight and reinforces the rear end of the car at the same time.

Separate springs and shock absorbers provide the necessary vertical support. The twin-tube gas-filled shock absorbers are fitted right next to the wheels, leaving space for a particularly generous through-loading width in the luggage compartment.

The anti-roll bar at the rear is mounted on extra-firm rubber/metal bearings fitted to the axle subframe, efficiently reducing body sway and helping to improve the transmission of lateral forces and, accordingly, the handling of the car.

The front suspension

A new feature of the McPherson front suspension with lower triangulated control arm is the subframe bolted to the front end. The crossbars and wishbone mounts are made from aluminium which helps to save 1.5 kilograms in weight.

Again as a new feature, the anti-roll bar is mounted directly on the spring strut. This direct connection helps to improve the response of the anti-roll bar, allowing the engineers to make the whole unit smaller and more compact than before, again saving 1.6 kilograms on the front axle.

The front wishbone mount is extra-stiff and firm to provide good lateral support. The rear wishbone mount, in turn, has a non-linear characteristic ensuring good ride comfort under minor loads and controlled self-steering behaviour as forces increase.

Safety

An Electronic Stabilisation Program of the latest generation, ESP, ensures active safety reserves at all times. The enhanced control algorithm in the electronic control unit now enables ESP to recognise potentially critical situations at an even earlier point in time, intervening preventively whenever necessary. With its self-learning capacity, ESP consistently monitors the car even under stable driving conditions, thus adjusting the intervention point to the current driving situation on the road. ESP intervenes much earlier in critical situations and, on the other hand, prevents unnecessary actions.

The body

The new Audi A3 is a wonderful example of the many options and benefits offered by a modern steel bodyshell, combining superior stiffness - which also means excellent vibration comfort - with supreme resistance in a crash and efficient lightweight technology.

This synthesis is made possible by the specific use of strong and extra-strong body panels, tailored blanks varying in width as well as the most advanced and sophisticated joining technologies. In all, the share of strong and extra-strong steel panels on the new A3 is no less than 62 percent. Static torsional rigidity is up by an impressive 33 percent as a result.

Stable structures for passive safety

Within the passenger compartment, exact coordination of all restraint systems as well as kinematic action of the steering column and pedals keeps forces acting on the occupants to a minimum. Full-size front airbags for the driver and front passenger as well as belt tensioners and belt-force limiters reduce the forces acting on the occupants' bodies in a head-on collision. Special padding on the steering column and in the footwells as well as the foot rest and the bottom-hinged accelerator pedal protect the driver's lower extremities, particularly the sensitive joints.

In a collision from the side the occupants in the A3 benefit from the particularly strong and solid structure of the bodyshell. The central sill profile, in turn, avoids any major deformation and, together with the extra-large seat cross members, guarantees very good support which is particularly helpful under very substantial local loads, in a pole impact for example.

Inside the car passengers are protected by seat-integrated thorax/pelvis side airbags. The sideguard head airbag system, which covers almost the entire window area from the A-post to the C-post and significantly reduces impact forces in the process, is standard in all new Audi A3 models in Western Europe.

The compact Audi is also protected with maximum efficiency from the effects of a head-on collision. Indeed, the Audi A3 already meets the requirements of future standards. This means that it safely resists an impact against a deformable barrier at up to 80 km/h and with at least a 70 percent overlap, the passenger cell and the fuel tank both remaining outside of the actual deformation area in such a collision. In addition, active head restraints on the front seats move forward in a rear-end collision to reduce the acceleration of the occupant's head as it shoots back.

Audi TT Coupé

Audi TT 3.2 quattro with sporty Direct Shift Gearbox DSG

Audi is presenting its TT sports car for the first time with V6 engine and innovative transmission technology adopted from motor racing, the Direct Shift Gearbox DSG. This enables a particularly dynamic transmission of power with an uninterrupted power flow during gear changes. The combination of the high-torque 3.2-litre engine with innovative sports gearbox and quattro permanent four-wheel drive emphasises the dynamic driving qualities of the Audi TT in a unique way. The 250 bhp version of the Audi TT Coupé 3.2 quattro completes the sprint from 0 to 100 kilometres per hour in 6.4 seconds, whilst its top speed is gently governed at 250 km/h. This model has an overall fuel consumption of 9.8 litres per 100 km.

The source of the power is the supreme 3.2-litre V6 engine with four valves per cylinder. This six-cylinder engine is particularly well-suited to the sporty Audi TT by virtue of its outstanding torque and power characteristics, especially in combination with the new Direct Shift Gearbox. It now delivers 184 kW (250 bhp) and a broad peak-torque range with a maximum value of 320 Nm from 2800 to 3200 rpm.

The valve control process generates only little friction thanks to the use of roller cam followers with hydraulic adjustment. In order to reduce emissions and further improve efficiency, the inlet and exhaust camshafts are continuously adjustable. The compression ratio is 11.3:1.

By virtue of its first-time application for the TT, the engine naturally complies with the EU 4 standard.

Throttle valve actuation is designed for an exceptionally agile, spontaneous engine response to accelerator pedal movements. The way it interacts particularly with the ultra-rapid, precise control technology of the new Direct Shift Gearbox with twin clutch opens up an entirely new dimension in propulsive power. The close connection between throttle and transmission control is made particularly apparent by active throttle blips during downshifts in the selector lever position S and in the manual gate.

The sound of the dual-branch variable exhaust system suitably reflects these sporting characteristics. A flap in the exhaust system is opened or shut depending on engine speed and the acoustics influenced accordingly. The sonorous sound never becomes over-assertive, even at high engine speeds, yet it unmistakably conjures up all the sentiments that sports-minded TT drivers appreciate.

The new Direct Shift Gearbox DSG

As is the case with the Audi A3 3.2 quattro, the revolutionary Direct Shift Gearbox DSG combines the advantages of a conventional six-speed manual gearbox with the qualities of a modern automatic transmission. The driver thus benefits from enormous agility and driving enjoyment with acceleration that is as harmonious as it is dynamic, without any interruption in the power flow. This is combined with good economy thanks to low fuel consumption, and convenient operation.

The suspension

The sporty TT suspension with its firm but comfortable tuning has been refined and adapted to suit the more demanding requirements of the new engine/transmission combination. The front suspension uses McPherson struts, whilst double wishbones with trailing arms are used at the rear.

The diameter of the anti-roll bars on the front and rear axles has been increased compared with the four-cylinder turbo versions. The spring/damper settings have been modified to cope with the increased power, in order to achieve a further improved driving performance. A special ESP/ASR and ABS application with integral brake assist takes account of the car's even more demanding handling and braking requirements.

A 17-inch dual-piston brake system adapted from the version used on the Audi RS 4 assures an appropriate braking performance. There are floating-calliper brakes with ventilated 334 millimetre brake discs at the front. The brake system familiar from the Audi TT quattro, with floating callipers and ventilated 265 millimetre discs, has been adopted at the rear axle.

The TT 3.2 quattro is fitted as standard with size 7.5Jx17-inch wheels of 6-arm "Wing" design and 225/45 tyres. Other 17-inch and 18-inch wheels of varying designs are available as an option.

Dynamic through and through

The dynamism of the new top-of-the-range TT is also in evidence elsewhere. The front apron has been aerodynamically optimised and incorporates side air apertures. It has larger air inlets to cover the increased cooling air requirements. The modified rear spoiler and a honeycomb-pattern diffuser trim are the distinguishing features at the rear. The larger rear spoiler further reduces rear-end lift, in response to the additional performance gain of the TT 3.2 quattro.

The TT 3.2 quattro also has xenon headlights with automatic range control and titanium-coloured headlight trims as standard.

Inside, this model is distinguished from other TT versions by an aluminium gearbox surround and an instrument cluster with a speedometer that reads up to 280 km/h. Shift paddles mounted on the steering wheel produce that genuine motor sport feel.

Like all TT models, the new version has an excellent safety equipment package, including two front airbags and pyrotechnic belt tensioners for the front seats. Head/thorax airbags in the front seat backrests afford protection in a side impact.

The standard automatic air conditioning makes sure that occupants feel comfortable in the Audi TT, no matter what the outside temperature may be. The driver information system also fits in well with the car's sporty image.

Audi TT - four-cylinder turbocharged engines

The TT Coupé stands for distinctive Audi design in its elementary form. Even the 1.8-litre inline four-cylinder engines with five valves per cylinder and turbocharger ensure that it performs like a true sports car.

The most powerful four-cylinder TT engine in the 1.8 T quattro goes about its work with vigour. With two intercoolers and a large K 04 turbocharger, this four-cylinder engine delivers 165 kW (225 bhp) and propels the TT Coupé up to a top speed of 243 km/h.

Turbocharging technology for outstanding performance

Acceleration and flexibility benefit from an ample 280 Nm of torque between 2200 and 5500 rpm. This sports car with quattro permanent four-wheel drive sprints from 0 to 100 km/h in 6.6 seconds. Power is distributed between the front and rear wheels via an electronically controlled Haldex clutch. This oil-immersed multi-plate clutch with separate oil circuit and its own electronic control unit is the heart of the four-wheel-drive system on the Audi TT.

In the middle Audi TT Coupé with front-wheel drive, a maximum power output of 132 kW (180 bhp) and a peak torque of 235 Nm between 1950 and 5000 rpm ensure dynamic performance. This TT needs just 7.8 seconds for the sprint from 0 to 100 km/h and reaches a top speed of 228 km/h. The same engine is also available in a version of the car with quattro permanent four-wheel drive.

Sporty performance with just 110 kW

Audi also offers a version of the TT which delivers 110 kW (150 bhp) at 5700 rpm. This power output accelerates the TT Coupé from 0 to 100 km/h in 8.6 seconds and on up to a top speed of 220 km/h. The engine's flat torque curve (210 Nm from 1750 to 4600 rpm) provides the basis for ample pulling power and thus aids an enthusiastic driving style.

TT with 6-speed tiptronic

The front-wheel-drive versions of the Audi TT Coupé and TT Roadster 1.8 T sports cars with 132 kW/180 bhp engine can be ordered with a six-speed automatic transmission.

Thanks to its six speeds, this particularly compact and lightweight transmission is noted for a wide overall ratio and can also transfer high levels of torque. Dynamic performance and high convenience come together to produce an impressive driving experience.

The car's performance figures speak for themselves, with acceleration from 0 to 100 km/h in 8.4 seconds and a top speed of 226 km/h. This model records an overall fuel consumption of 9.1 litres per 100 kilometres.

As usual at Audi, the tiptronic also allows sporty manual gearshifts. Thanks to the gearshift function integrated as standard into the leather-covered sports steering wheel, these are possible without taking a hand off the steering wheel.

The Dynamic Shift Program DSP permanently analyses the driver's style and adjusts the shift points continuously. In addition, the standard sport program in selector lever position S changes up later for even more dynamic results.

Sporty and safe: TT suspension

An advanced sporty suspension system provides the basis for the Audi TT Coupé quattro's excellent dynamic handling. The TT brake system, with four large discs, ABS and Electronic Brake-force Distribution EBD, is also designed for sports performance. The 165 kW (225 bhp) version of the TT has ventilated brake discs at the rear as well as the front.

The TT Coupé has an excellent safety equipment package, including ESP, two front airbags and pyrotechnic belt tensioners for the front seats. Head/thorax airbags in the front seat backs protect the upper body and head in a side impact.

Audi TT Roadster

To travel in an open-top Audi TT Roadster is to experience driving in its most original form. Its no-compromise design, its powerful presence and its inner values guarantee enthusiasm among all those whose passion for driving a sports car is allied to the feeling that there should be no fixed roof over one's head when doing so.

Two rollover bars, which form an integral part of the body structure, ensure the Roadster's safety and rigidity. Precisely calculated reinforcements in the sill areas and sturdy transitions at the joints between the A and B-posts and the floor assembly give the TT Roadster its excellent torsional rigidity.

The soft top with its large heated glass rear window can be opened and folded down in a single action. An electro-hydraulic soft top (standard on the TT Roadster 3.2 quattro) and an electrically retractable wind deflector made of safety glass are also available. The wind deflector's rounded edge follows the outline of the two rollover bars and prevents unwelcome turbulence.

Active safety plays a central role in the TT Roadster. Its standard equipment comprises the Electronic Stabilisation Program ESP including Electronic Differential Lock EDL, Electronic Brake-force Distribution EBD and Anti-Slip Regulation ASR.

Large disc brakes and ABS ensure outstanding deceleration figures. Ventilated brake discs are fitted at the front; the TT 3.2 quattro and 165 kW (225 bhp) TT Roadster 1.8 T quattro have them at the rear too.

The Audi A4

Innovative technology and distinctive styling are the characteristic features of the current A4 generation. With its clear contours, the A4 body translates discreet sportiness into consistently modern architecture: a styling principle which provides a fitting context for aerodynamic perfection and characteristic Audi dynamism to take shape. A drag coefficient of just 0.28 and a level of torsional rigidity that is outstanding, and not just in this class, distinguish the A4 body, as does the use of advanced lightweight technology for even the smallest of details. Powerful yet economical petrol and TDI engines provide the basis for excellent performance figures. All petrol engines comply with the limits specified by the EU 4 standard, as do the 2.5 TDI diesel versions with 120 kW (manual gearbox and multitronic) and 132 kW (six-speed manual gearbox).

New manual gearboxes

A new generation of manual gearboxes is to be introduced in the 2004 model year. Gear-shifting dynamics benefit from equally short shift travel and, thanks to effective mechanical decoupling, there are no vibrations to be felt at the gear lever. Reduced effort, a lower weight and better efficiency have also been achieved.

The petrol engines for the Audi A4

The most powerful model in the Audi A4 range is the 3.0 V6 with five-valve cylinder head. This engine produces 162 kW (220 bhp) from 2976 cc at 6300 rpm. Its peak torque of 300 Nm is available at 3200 rpm. The A4 saloon with front-wheel drive and five-speed manual gearbox is consequently able to accelerate from 0 to 100 km/h in 6.9 seconds, and on to a top speed of 245 km/h. This version has a fuel consumption of 9.5 l/100 km.

The 125 kW (170 bhp) six-cylinder engine with a capacity of 2.4 litres produces 230 Nm of torque and powers the Audi A4 2.4 to a top speed of 226 (multitronic 222) km/h. This supreme power from any speed contributes as much to driving pleasure as the brisk acceleration from 0 to 100 km/h in 8.9 seconds.

The V6 engine with its sporty six-cylinder sound and exemplary smooth running is a pleasure to listen to.

The Audi A4 2.0 FSI with petrol direct injection develops 110 kW (150 bhp) and is available in conjunction with front-wheel drive and five-speed manual gearbox. The 2.0 FSI reaches its peak torque of 200 Nm at between 3250 and 4250 rpm. The saloon with five-speed manual gearbox completes the sprint from 0 to 100 km/h in just 9.6 seconds and reaches a top speed of 218 km/h.

However, FSI engines are noted not only for their dynamism, but also for their outstanding efficiency. In view of the performance figures achieved, an average consumption of 7.1 litres of Super Plus petrol per 100 kilometres is currently better than any of this car's key competitors.

The Audi A4 1.8 T demonstrates just how much power and refinement a modern turbo engine can have. Two power ratings of the most potent four-cylinder engine in the Audi A4 are available. The 120 kW version reaches a top speed of 228 (multitronic 223) km/h and accelerates from 0 to 100 km/h in 8.6 seconds.

The version with a power output of 140 kW reaches a top speed of 236 km/h and 100 km/h in just 8.2 seconds. With an average fuel consumption of 8.6 l/100 km, it consumes just 0.4 l per 100 km more than the 1.8 T with 120 kW engine.

On the Audi A4 2.0, the peak torque of 195 Nm is available at 3300 rpm. The inline four-cylinder engine achieves its maximum power output of 96 kW (130 bhp) at 5700 rpm. It propels the A4 saloon with front-wheel drive and five-speed manual gearbox to 100 km/h in 9.9 seconds, and on to a top speed of 212 km/h. And considering this model consumes only 7.9 litres of fuel per 100 km, these figures certainly are impressive.

The 1.6-litre four-cylinder version with an output of 75 kW (102 bhp) is available as the entry-level petrol model.

The diesel engines for the Audi A4

The range of diesel models starts at 74 kW from a displacement of 1896 cc. The same-capacity four-cylinder version with pump-injector fuel injection develops an output of 96 kW (130 bhp) and achieves an average fuel consumption of just 5.5l/100 km. This model reaches a top speed of 210 km/h and accelerates from a standstill to 100 km/h in less than ten seconds. The 70-litre fuel tank enables operating ranges of up to 1300 km.

Above this are two 2.5 TDI engines developing 120 kW (163 bhp) or a hefty 132 kW (180 bhp) and combined with a six-speed manual gearbox. These engines deliver their power to the road either via the front wheels (120 kW) or by means of quattro permanent four-wheel drive (132 kW). Drivers who prefer to have the gears changed for them can opt for the continuously variable multitronic (120 kW) or five-speed tiptronic (132 kW) transmission.

The suspension

With its low unsprung mass and self-tracking trapezoidal-link rear axle, the lightweight aluminium suspension ensures outstanding driving dynamics. Good steering precision and exact handling complement the first-class ride comfort of the A4 saloon.

All Audi A4 models are fitted with the latest-generation Electronic Stabilisation Program ESP as standard. As an integral part of the latest ESP generation, hydraulic brake assist is part of the standard specification. This system helps the driver in emergency braking situations by automatically increasing braking pressure.

The Audi A4 offers maximum interior comfort. As well as plenty of knee room for both front and rear passengers, there is also extra space for the head and shoulders. With a capacity of 445 litres, the smooth-floored luggage compartment is well-equipped for tackling more challenging transport tasks.

The body's high rigidity, high-grade materials with an excellent finish, the car's unique ride comfort and extremely effective insulation against irritating wind and driving noise live up to expectations in the luxury class.

The Audi sideguard head airbag system is part of the basic package and covers almost the entire side window area, from the A-post to the rear compartment. The intelligent crash sensors for the front airbags detect the severity of an accident and thus ensure controlled activation of the airbags.

Audi A4 Avant: dynamic, elegant and versatile

The Audi A4 Avant unites dynamism and design, elegance and versatility like no other car in its segment. Its styling is dominated by purity and clarity. The high waistline and subtle wedge shape are typical Audi design characteristics.

Space and high variability

As well as the generous passenger compartment, the smooth-floored luggage area, whose width of 1000 millimetres between the wheel arches is outstanding in the B-segment, offers a particularly high standard. This is made possible by the space-saving construction of the self-tracking trapezoidal-link rear axle, which is also to be found on the current A4 saloon.

This was laid out to suit the specific needs of the Avant as a load carrier, right from the initial design phase. The A4 Avant has a luggage capacity of 442 litres which can be increased to 1184 litres by folding down the rear seat back.

The A4 Avant's ingenious variability is also an eye-opener. The rear backrest can be folded asymmetrically in a ratio of 1/3 to 2/3. A standard combined housing behind the seat backs contains the luggage cover and the dividing net between the passenger and load areas. The housing folds down together with the larger section of the rear seat and can easily be removed through the rear side door.

The Audi A4 Avant has a 65-litre storage compartment under the double floor of the luggage compartment. The floor can be folded together, positioned upright behind the rear seats or removed completely. The body-mounted plastic tray is ideal for transporting dirty objects.

The tailgate of the A4 Avant also demonstrates its commitment to systematic functionality. It opens wide and can be closed easily from either the right or the left side with the aid of two recessed handles.

Interior and equipment of superior quality

The architecture of the horizontal lines surrounding the driver creates a genuine sense of safety allied to an impression of a generous amount of space. The materials used and their finish give the Audi A4 the quality level of a luxury car, something that is apparent not only throughout the cabin, but also in the luggage compartment.

The Audi A4 Cabriolet

As the emotionally charged spearhead of a sporty model series, the Audi A4 Cabriolet is dynamic, exclusive and of a superb technical standard; its equipment specification covers every conceivable requirement.

This four-seater convertible, which is 4.57 metres long and 1.77 metres wide, has an electro-hydraulically operated hood with a heated glass rear window as standard. Outstanding acoustic insulation and excellent suitability for winter conditions are typical characteristics of an Audi Cabriolet hood.

Another aspect that can be taken for granted is the outstanding material quality and finish of the interior. The sporty but elegant interior design, perfectly matched to the dynamic styling of the exterior, produces a harmonious overall impression.

Maximum agility and therefore sheer driving pleasure are also guaranteed by the car's lightweight aluminium suspension, based on the much-praised axle design of the new A4 generation. This distinctly dynamic performance is complemented by the high torsional rigidity of the Cabriolet body. The most important consequence of this characteristic is a level of vibrational comfort that makes the A4 Cabriolet the new benchmark in its class.

The car's safety also benefits from the body's rigid structure. The development engineers' objective was to match the A4 Cabriolet's stability and crash resistance to that of the A4 saloon.

An active roll-over protection system provides additional safety if the car overturns. In this case, two protective bars, controlled by sensors, are triggered behind the rear passengers within milliseconds. Together with the extremely rigid windscreen frame, they help to preserve survival space for all occupants if the car turns over.

All Audi A4 Cabriolet models comply with the EU 4 standard.

Engines

A supreme power development is a common feature of all four engine versions. The three-litre six-cylinder unit develops 162 kW (220 bhp). It accelerates the A4 Cabriolet extremely smoothly from a standstill to 100 km/h in 7.8 seconds and enables it to reach a top speed of 243 km/h.

A 2.4-litre six-cylinder version is also available. 125 kW (170 bhp) ensure vigorous pulling power in all situations and outstanding refinement - characteristics that make it an extremely pleasant companion for open-top driving.

The four-cylinder turbo engine of the Audi A4 Cabriolet 1.8 T develops an output of 120 kW (163 bhp). This version is also impressive for its outstanding dynamism: it accelerates from 0 to 100 km/h in 9.4 (multitronic: 9.3) seconds and reaches a top speed of 226 (multitronic: 219) km/h.

Audi A4 Cabriolet V6 TDI

Audi offers a third, overtly sporty six-cylinder version in the form of the A4 Cabriolet 2.5 TDI. 120 kW (163 bhp) and a hefty torque of 310 Nm in a range from 1400 to 3600 rpm ensure power in all situations. The car takes just 9.9 seconds to accelerate to 100 km/h and, in combination with the six-speed manual gearbox, does not reach its top speed until 225 km/h.

In conjunction with the V6 TDI, the Audi A4 Cabriolet introduces a brand new dimension to transmission technology, unique in the convertible segment, with its continuously variable automatic transmission, the multitronic. This transmission offers the dynamic qualities of a manual gearbox and surpasses the comfort of a conventional automatic. It is therefore possible either to cruise along smoothly - a manner of driving preferred by convertible drivers - or to adopt a distinctly dynamic style.

The TDI's proverbial economy means a saving in terms of fuel consumption that is unrivalled in this class: it consumes an average of just 7.2 litres of diesel every 100 kilometres.

Even greater freedom: Audi A4 Cabriolet models with quattro drive

The powerful three-litre V6 and the high-torque 1.8 T turbo engine can also be combined with quattro permanent four-wheel drive. Both versions are available with a six-speed manual gearbox, the 3.0 can also be ordered as a five-speed tiptronic version.

The four-seater Audi A4 Cabriolet quattro is the only car of its kind worldwide to offer permanent four-wheel drive. The quattro driveline underlines the status of the A4 Cabriolet as the sportiest all-rounder in its class.

At the same time, permanent four-wheel drive makes the A4 Cabriolet the ideal all-season vehicle. Engine power can be safely converted into forward propulsion in all road and weather conditions.

More dynamic than ever: the Audi A6

The Audi A6 has set new trends since its launch in 1997. The saloon's progressive design in particular introduced a new, long-lasting benchmark.

The TDI engines - also with multitronic

The 120 kW (163 bhp) 2.5-litre V6 TDI and the continuously variable multitronic transmission can be described as a particularly attractive dream team in the A6.

80 percent of the engine's peak torque of 310 Nm is available at just over 1000 rpm. Acceleration is equivalent to that of a model with manual gearbox. The saloon reaches 100 km/h in 9.3 seconds and a top speed of 217 km/h.

But the multitronic's real strength comes to the fore in the area of fuel consumption. In view of this vehicle's performance and the level of comfort offered, just 6.9 litres of diesel per 100 km is a sensationally low figure.

The more powerful version of the 2.5 TDI V6 is also distinguished by tremendous low-end torque and excellent refinement. This engine develops 132 kW (180 bhp) at 4000 rpm; its peak torque of 370 Nm is available from 1500 to 2500 rpm.

Dynamic potential is also the characteristic feature of the 1.9-litre TDI four-cylinder engine with high-pressure pump-injector fuel supply. Thanks to its 96 kW (130 bhp), it too has no trouble making rapid progress. It accelerates from a standstill to 100 km/h in just 10.5 seconds; 285 Nm ensure pulling power even from low revs.

At 203 km/h this model's top speed is of a calibre that leaves nothing wanting in this vehicle category. Especially as this performance goes hand in hand with typical TDI modesty when it comes to fuel consumption: just 5.7 litres for 100 kilometres. This A6 can consequently cover distances in excess of 1200 kilometres without having to stop for fuel.

The petrol engines

Audi offers a sporty engine with aluminium block in the form of the 3.0 version. This V6 produces 162 kW (220 bhp) from 2976 cc at 6300 rpm. Its peak torque of 300 Nm is available at 3200 rpm. The A6 3.0 reaches a top speed of 243 km/h and completes the 0-100 km/h sprint in just 7.5 seconds. Its average fuel consumption is recorded at just 9.7 litres per 100 km.

Supreme power and ample torque for the 2.4 and 2.7 T

Power and refinement are also among the strengths of the other six-cylinder engines in the A6 range. The 2.4-litre version produces 125 kW (170 bhp) and 230 Nm of torque.

The biturbo 2.7 T sets about its work even more energetically, mobilising 184 kW (250 bhp) and 350 Nm of torque. This provides the ideal basis for even more agility and even more driving pleasure than before.

In combination with the standard 6-speed gearbox, a top speed of 248 km/h is possible; the 2.7 T, which is available exclusively with quattro permanent four-wheel drive, accelerates from 0 to 100 km/h in 6.8 seconds. A fuel consumption of 11.6 litres per 100 kilometres testifies to its efficiency.

The 2.0-litre engine

The Audi two-litre four-cylinder engine is the lightest in its class, tipping the scales at 129 kilograms, and also the most compact power unit, measuring only 460 millimetres in length. It produces 96 kW (130 bhp) from a capacity of 1984 cc.

The 2.0 engine version produces its peak torque of 195 Nm at 3300 rpm and its maximum power output of 96 kW (130 bhp) at 5700 rpm. It propels the saloon with front-wheel drive and five-speed manual gearbox to 100 km/h in 10.5 seconds, and on to a top speed of 205 km/h - consuming just 8.3 litres of fuel per 100 km.

The 1.8 T engine

The 1.8 T four-cylinder engine with its 110 kW (150 bhp) demonstrates just what a modern turbocharged four-cylinder engine is capable of. The A6 with this engine version reaches a top speed of 216 km/h and accelerates from 0-100 km/h in 9.7 seconds. Its torque of 210 Nm is developed at just 1750 rpm and remains constant up to 4600 rpm.

This means that peak torque is always available in the predominantly used engine-speed range. The Audi A6 1.8 T with front-wheel drive and manual gearbox consumes just 8.4 litres of Super petrol per 100 kilometres.

In a class of its own: the V8 4.2

Classy, dynamic, refined and incredibly powerful: these are the outstanding features of the 4.2-litre V8 engine. This engine develops 220 kW (300 bhp). The broad peak-torque range is even more impressive: a constant 400 Nm between 3000 and 4000 rpm. The A6 saloon with five-speed tiptronic accelerates up to 100 km/h in just 6.9 seconds. Its (governed) top speed is 250 km/h.

The V8 has one variable camshaft system per bank of cylinders, to vary the valve timing of the inlet camshafts according to the engine speed range. Low emissions, quiet idling and an ample torque pattern are the outcome.

multitronic: smoothness perfected

With its multitronic Audi has developed a continuously variable transmission which avoids the previous drawbacks of this principle and exploits all its advantages in the interest of optimum gearshift strategies. The big difference with multitronic is that, for the first time, the gain in convenience is not at the expense of dynamism or operating economy. Shift points are adapted by an additional sport program..

The differences compared with the conventional geared automatic transmission with torque converter are even more impressive, the latter being prone to transmission losses due to its fundamental concept. A further advantage of the multitronic compared with even the most modern torque converter transmissions is that the gearshifts are entirely jolt-free.

An infinite number of transmission ratios

On all previous transmission types, specific transmission stages are physically present inside the transmission casing, in the form of five or more gear pairs or planetary gear trains.

On the continuously variable transmission, on the other hand, there is just one pair of gears with a flexible transmission belt, which permits an infinite number of transmission ratios. Instead of the thrust belt which is commonly found on CVTs, the multitronic uses a steel link-plate chain which is almost as flexible as a V-belt.

The multitronic is available for the front-wheel-drive versions of the 1.8 T und 2.0 petrol models, for the 2.4 and 3.0 V6 versions and in combination with the 1.9 TDI and 2.5 TDI (120 kW) diesel engines.

tiptronic with sport program

All quattro versions of the A6 (except the 1.8 T) and the 132 kW variant of the 2.5 TDI with front-wheel drive are available with the five-speed tiptronic transmission. As well as the option of manual gearshifts in the tiptronic gate, this convenient automatic transmission offers an additional sporty gearshift program. In the "S" position, the transmission changes up later and down earlier. The driver thus benefits from higher traction and can make even better use of the engine's agility up into high speed ranges.

quattro permanent four-wheel drive

Around 45 percent of all new Audi A6 models sold in 2002 had four-wheel drive. With the exception of the 120 kW TDI, Audi offers all V6 engines, the 1.8 T and the V8 power unit for the A6 either optionally or as standard in conjunction with quattro permanent four-wheel drive.

The suspension

Four-link front suspension with numerous aluminium components and the elaborate design of the rear suspension are a guarantee of first-class comfort and excellent handling, on both front-wheel-drive versions and quattro models. As an integral part of the latest ESP generation, hydraulic brake assist is part of the standard specification. This system helps the driver in emergency braking situations by automatically increasing braking pressure.

Safety as the priority

The subject of safety naturally has an important role to play in the philosophy of the Audi A6 in general. The most apparent evidence of this is the sideguard head airbag system, which is standard equipment for all A6 versions on the German market. This pioneering concept incorporates a large-area airbag on both the right and left sides, covering practically the entire window surface. The A6 thus provides additional protection for the head and neck of the occupants of the outer seats in the event of a side or oblique impact.

There are in addition two full-size front airbags and thorax/pelvis side airbags for the driver and front passenger. Side airbags for the two outer rear seats are moreover available as an option.

Audi allroad quattro

The allroad quattro combines the dynamic luxury of a top-class model with the outstanding off-road capability of a fully fledged all-terrain vehicle. Its muscular design is derived from the body of the A6 Avant and accentuates its high functionality and elegant dynamism in a new way.

As befits an ideal leisure and touring vehicle, the Audi allroad quattro has a highly variable interior with subtle nuances. Comfortable seating for up to five people or a vast load area with a maximum volume of 1590 litres open up numerous possibilities for which the allroad quattro is well-equipped thanks to a payload limit of 630 kilograms. An additional strength: with a stabilising device, the allroad quattro is allowed to tow loads of up to 2300 kilograms on a maximum gradient of 12 percent.

The engines

There is a choice of four powerful engines for the allroad quattro, all with extremely substantial torque and power potential. The top of the range in terms of power and refinement is the compact 4-2-litre V8 engine which delivers 220 kW (300 bhp). The six-cylinder 2.7 T version with twin turbochargers produces 184 kW (250 bhp).

The two allroad quattro 2.5 TDI versions, rated at 132 kW (180 bhp) and 120 kW (163 bhp) respectively, also guarantee a dynamic build-up of engine power and mighty pulling power despite economical fuel consumption of 8.7l/100 km.

On all kinds of terrain, quattro permanent four-wheel drive converts this power with unfailing efficiency into forward movement. Exclusive to the allroad quattro is the driver-engaged low range ratio, an option on the 2.7 T and 2.5 TDI (132 kW) versions with manual-shift gearbox, for optimum progress across tough terrain and on extreme uphill gradients.

4-level air suspension

A specialist vehicle for all kinds of surfaces needs variable ground clearance. Audi's developers have satisfied this demand for the allroad quattro using an electronically regulated air suspension system.

This system enables the ground clearance to be varied by as much as 66 millimetres, with four distinct ride heights between 142 and 208 millimetres at the driver's disposal: a broad basis for all driving conditions, with either a low centre of gravity or extra ground clearance available as the situation demands. Integrated ride height control keeps the selected level constant automatically, regardless of changes in the vehicle's payload or weight distribution. The intelligent control unit selects ground clearance according to road speed.

Audi A8: a new dimension in sporting luxury

With its compelling handling, pioneering technology and exclusive design and equipment, the new Audi A8 redefines the notion of sports appeal in the luxury segment. The saloon unites technical properties that set it clearly apart from the competition in its class. As the brand flagship, the A8 embodies the characteristics of the future Audi generation through sporting dynamism and clear design, innovative technology and top quality.

Also as a long-wheelbase version: A8 L

There is no doubt that the Audi A8 L is the ultimate luxurious long-distance saloon car. With its wheelbase extended by 130 millimetres to 3074 millimetres, this model offers not only the dynamic potential of the A8, but also the opportunity to travel in style in the spacious rear compartment. The front-passenger seat can be adjusted from the rear so that the person sitting behind it can increase their legroom to 1075 millimetres.

Electrically adjustable individual seats, with massage function and seat heating/ventilation as an option, are also available.

Drive: power used to the full

Three powerful V8 engines are available: two petrol versions with a capacity of 4.2 and 3.7 litres which produce 246 kW (335 bhp) and 206 kW (280 bhp) respectively, and the world's most powerful eight-cylinder diesel engine in a production saloon with an output of 202 kW (275 bhp). The six-speed automatic transmission with tiptronic function constantly assures an optimum transition between the various speed stages.

quattro permanent four-wheel drive translates engine performance into superbly effective propulsion and cornering stability.

Aluminium body: progress through lightness

The innovative aluminium body, based on a refined version of the Audi Space Frame (ASF), provides the high-strength basis for low weight, a dynamic performance and excellent handling. Engineers succeeded in reducing the number of components on the continuous ASF compared to the first A8 generation through the use of large functional castings and extruded sections. Static torsional rigidity was increased by 60 percent and ensures a major improvement in vibrational comfort, safety and dynamic handling potential.

Running gear: further increased dynamism if the driver so chooses

The Audi A8 has an aluminium chassis with four-link front suspension and self-tracking trapezoidal-link rear suspension. The brakes and steering system with variable ratio and servotronic are a new design.

Adaptive air suspension - an electronically controlled air suspension system with continuous damper control - solves the classic conflict of aims between good handling properties and suspension comfort commensurate with the luxury class. The data from four sensors on the axles and three acceleration sensors on the body is evaluated in the adaptive air suspension's central control unit. This computer prompts the adjustment of the individual shock absorbers in a matter of milliseconds, based on the driving situation identified, thereby assuring optimum handling and ride comfort at all times.

The driver can choose between four predefined settings, for a suspension characteristic ranging from overtly sporty to ultra-comfortable. The ride height can also be varied in this way.

The steering

The A8 has rack-and-pinion steering with a variable ratio and speed-dependent power assistance, servotronic, as a standard feature. The result is improved steering precision and clear feedback at high speeds without any loss in comfort at low speeds.

With high-performance brake system

The Audi A8 has a newly developed high-performance brake system with generously dimensioned aluminium floating-calliper brakes. With 360 millimetre brake discs at the front and 310 millimetre discs at the rear, the system now achieves a braking performance in conjunction with 17-inch wheels that was previously only found in combination with 18-inch systems. The brake system is assisted by the Electronic Stabilisation Program ESP.

Electromechanical parking brake

As well as performing all the tasks of a conventional handbrake, the electromechanical parking brake on the Audi A8, which is operated at a pull/push control on the centre console, offers functional benefits. A starting assist function makes it easier to pull away smoothly on hills without the driver even having to release the brake. It goes without saying that the parking brake has an emergency braking function.

Wheels and tyre pressure monitoring system

The 3.7-litre and 4.2-litre versions of the A8 have the elegantly sporty 10-hole 8Jx17" alloy wheels as standard, with size 235/55 R17 tyres. Further wheel versions up to 20 inches in diameter (tyre format: 255/35 R20) are available as an option.

This is the first luxury-class vehicle to be available with cast aluminium wheels with run-flat properties, the so-called PAX system. Their design means that the driver can continue for up to 200 kilometres at a maximum speed of 80 km/h even if a tyre is fully deflated.

MMI operating concept: maintaining diversity, reducing complexity

With its integrated user interface MMI, Audi offers an infotainment platform and user concept for the new A8 that keeps operation simple through stringent logic. MMI in the first instance comprises the control panel (MMI terminal) on the centre console with a control button that can be turned and pressed and four control keys grouped around it.

On either side of the terminal - apart from the Return key for exiting the menu level - there are a total of eight function keys with which the user can call up the most important main menus directly. The second central component of the MMI, a 7-inch colour monitor, is positioned above the centre console in the dashboard and therefore at an optimum angle of view for the driver.

The basic geometry of the monitor display corresponds in detail to the layout of the control keys and button in the MMI terminal. There is thus an intuitive link between visual perception and hand movements. The more frequently a function is used in the car, the higher up the menu structure it is placed, thus making it quicker and easier to access.

The electronics architecture

The field of electronics has long since advanced into automotive technology. This applies in particular to the luxury segment where driver expectations regarding communication and convenience systems naturally play a very important role.

The new A8 therefore offers numerous innovative technologies in this area, some of which are available for the very first time in an Audi. These include, to name just a few examples, the advanced key access and authorisation system, one-touch memory personalisation and the radar-assisted distance control system known as adaptive cruise control.

Audi S models

A commanding performance and conscious understatement in their appearance, added to unlimited roadworthiness: these characteristics are featured in all of the Audi S models where they combine to form a perfectly harmonised vehicle concept. Every version has quattro permanent four-wheel drive. This enables the performance potential to be translated into reliable traction and driving enjoyment whatever the situation.

Audi S4 and S4 Avant

The Audi S4 is the sporty top model in the A4 range. Its compact V8 engine with chain drive at the rear and a displacement of 4.2 litres delivers 253 kW (344 bhp) and 410 Nm of torque.

The eight-cylinder engine's thrust enables the Audi S4 with six-speed manual gearbox to complete the 0-100 km/h sprint in just 5.6 seconds. It takes just 20.6 seconds to reach 200 km/h, whilst the top speed is a governed 250 km/h. A version with six-speed tiptronic is also available.

The Audi S4 is the only car in its class to have quattro permanent four-wheel drive. It can therefore convert its engine output into propulsive power most efficiently at all times and enter a new dimension of superiority thanks to the handling potential of its aluminium chassis.

The Audi S4 is outstanding for its unique combination of unmistakeable style and sporting exclusivity, of individuality and versatility. Available as both a saloon and an Avant, it also offers its owner excellent everyday quality.

Audi S6 and S6 Avant

On both S6 models, the saloon and the Avant, the hood conceals a 4.2-litre V8 engine with five valves per cylinder which develops 250 kW (340 bhp). The power flow from this eight-cylinder engine is impressive, with a torque of 300 Nm available just slightly above idle speed, rising to a maximum of 420 Nm at 3400 rpm. Top speed is electronically governed to 250 km/h. The S6 sprints from 0 to 100 km/h in 6.7 seconds, the S6 Avant takes 6.8 seconds.

A five-speed tiptronic transmission with ratios chosen to suit the car's sporting character delivers power to the quattro permanent four-wheel drive, which in turn transmits it with supreme reliability to the road. A direct steering ratio ensures a particularly agile and precise response to steering wheel movements.

The flared wheel arches accommodate 17-inch cast aluminium wheels. Polished aluminium exterior mirrors and two visible stainless steel tailpipes add further visual touches.

Audi RS 6: High performance with supreme personality

The Audi RS 6 sets new standards with its tremendous power development, quattro drive, its brake system and the innovative DRC suspension. It is available as both a saloon and an Avant. This, the brand's most powerful model to date, was developed by quattro GmbH in conjunction with AUDI AG.

Engine power from plentiful resources

The 4.2-litre V8 engine in the Audi RS 6 reaches a peak output of 331 kW (450 bhp) between 5700 and 6400 rpm. The fact that its maximum torque of 560 Nm is available across an extremely wide speed range of between 1950 and 5600 rpm is exceptional.

High-performance brake system

The Audi RS 6 is fitted with brake discs of a composite design derived from the world of motorsport. An aluminium brake-disc chamber minimises weight and consequently ensures a low unsprung mass.

The ventilated disc brakes have a diameter of 365 millimetres at the front and 335 millimetres at the rear. 8-piston fixed callipers are used at the front, single-piston floating-calliper brakes with integral handbrake at the rear.

Dynamic Ride Control to prevent rolling and pitching

The Audi RS 6 is the first model to be equipped with the innovative suspension concept Dynamic Ride Control DRC. It consists of a special damping system that counteracts rolling and pitching movements of the vehicle body without the use of electronics.

When steering into and around a corner, the damper characteristic is varied in such a way that movements around the longitudinal axis (rolling) are significantly reduced. DRC counteracts vehicle movements around the transverse axis (pitching) when accelerating or braking according to the same principle.

Interior and equipment

Sports appeal and individuality are the characteristic features of the exclusive interior equipment of the Audi RS 6. The Recaro sports seats with special upholstery and embossed RS 6 logo provide stability, optimum lateral support and ample comfort however long the journey may be. The steering wheel rim and selector lever knob are trimmed with perforated leather. The gearbox gate has a matt brushed aluminium surround, the inside door handles are coated with matt black anodised material.

The standard safety equipment includes airbags for the driver and front passenger, side airbags at the front and the Audi sideguard head airbag system.

Audi RS 6 Sport

Customers can opt to have their Audi RS 6 made even sportier by quattro GmbH: the sports brake system with eight-piston brake callipers at the front withstands maximum loads. Perforated discs underline the car's sporty look.

The sound of the eight-cylinder biturbo engine is even more fascinating thanks to a sports exhaust system with matt black tailpipes. Inside, suede trim on the three-spoke steering wheel and gear knob afford an excellent grip.

S line, the Audi sport range

Anything sporty has always been given the designation "S" at Audi. The sporty S line has established itself as the equipment line that links the A model series and the super sporty S models, the Audi S4/S4 Avant and the S6/S6 Avant.

S line is offered for the entire model range with the exception of the allroad quattro and the A8. The S values and the positive image radiated by the S models are thus also accessible to those customers who do not require an engine output of 340 bhp or more.

S line equipment can be ordered directly from AUDI AG, but is developed by quattro GmbH. Over the past 20 years or so, quattro GmbH has earned itself a respected reputation as the developer of sporty customisation packages and high-performance cars such as the RS 4 and RS 6.

Basic features which the S line equipment packages have in common include at least 17-inch cast aluminium wheels of unmistakeable design, custom-built sports suspension, sports seats, a sports steering wheel and S line badges. S line is divided into a suspension package, an exterior package and a sports package depending on the model and the customer's requirements.

This means that greater variety can be made visible on both the inside and the outside of the vehicle. The S line includes items that are either otherwise not available or that cannot be ordered separately.

Audi exclusive: From series product to unique specimen

The next stage in the process from merely making differentiating changes to a production vehicle all the way to actual customisation is offered by the "Audi exclusive" range. quattro GmbH customises Audi vehicles precisely according to the buyer's personal preferences and tastes. From special paint finishes and extended leather equipment packages to carpets in the customer's favourite colour and fine wood inlays - virtually anything is possible.

Examples include a special leather package for the sports seats of the A4 Cabriolet with contrasting leather piping running across the seat surface, darker tinted windows for the A6, an elegant full paint finish for the allroad quattro, rear seat entertainment for the Audi RS 6, an office package for the Audi A8 including telephone and fax to make it easier to work in the back of the car on journeys and a folding table, cool box and bar compartment.

High-tech bikes, design courtesy of Audi

The Audi Cross Pro and Audi Cross bikes reflect the same expertise that is behind the brand's cars: sportiness, original design, innovative technology and top quality standards for materials and manufacturing.

Audi Design was responsible for designing these innovative and unique mountain bikes. quattro GmbH worked together with the Aluminium Centre in Neckarsulm on the development of the frame and seat tower. The partner company Centurion Renner KG is responsible for producing the bikes and for providing competent service.

Both Audi bikes have suspension and dampers at both the front and rear wheel. Whereas hydraulic elements take care of the damping, the suspension is either pneumatic or uses steel springs.

The hydraulic front and rear damping is adjustable. The damping response of the rear damper can be adjusted at a separate valve, from sensitive to sporty/taut. The Manitou Black suspension forks have precise compression and rebound adjustment which can be used to adapt suspension behaviour quickly and easily to suit every terrain. The adjustable travel of 80 or 100 mm underlines their considerable variability.

Hydraulic Magura disc brakes with perforated discs provide excellent braking power from only slight operating pressure. The drive and shifting components are from Shimano's top series, XT and Deore.
