Melbourne – Mercedes-Benz presents its new range-leading SUV: the all-new GL-Class. This all new premium off-roader is available in either the V6 diesel GL 320 CDI or petrol GL 500. Customers interested in the multi-purposed GL-Class, which can optionally seat up to seven people, can speak with their local Mercedes-Benz dealer.

The GL-Class offers excellent handling both on and off-road and pampers occupants with its extremely spacious accommodation and the comfort of a luxury saloon. The GL-Class sets another milestone with the PRE-SAFE® safety system, a first in this market segment.

The entry level GL 320 CDI delivers 165 kW, while its ample 510 Newton meters are on tap across a wide range of engine speeds. Despite all of this power, the engine only burns 9.8 litres of die-sel per 100 kilometers.

The GL 500 features a newly developed 5.5 litre V8 petrol engine with a rated output of no less than 285 kW. Both engines are teamed up with the 7G-TRONIC automatic transmission with DI-RECT SELECT as standard.

“The GL-Class combines superior on and off road capabilities in total luxury”, said Horst von Sanden, managing director respon-sible for Mercedes Car Group in Australia.

“Mercedes-Benz has a long and proud history of off-road exper-tise and the new GL-Class builds on this. With the standard inclu-sion of the Off-road Pro Engineering package, AIRMATIC air sus-pension and a unique sense of luxury, the GL–Class blends com-fort and driving performance, two hallmarks of the Mercedes-Benz brand.

“The GL-Class allows us to meet additional customer needs, pro-viding a large versatile vehicle with seven seats optionally avail-able.”

The distinctive design of the GL-Class exudes power and exclusiv-ity. Calm body surfaces, powerful, wedge-shaped features and striking details give the impression the luxury off-roader is surg-ing forward even when stationary. The spacious body (length 5088 mm, width 1920 mm, height 1840 mm) is beautifully pro-portioned.

The GL-Class is surprisingly agile with 4MATIC- the permanent all-wheel-drive system from Mercedes-Benz, helping to give the GL-Class superior handling dynamics under any conditions. The GL-Class not only cuts a good figure on the road, it also shines as a genuine off-roader. The standard specification Off-Road Pro en-gineering package considerably enhances the car’s off-road ca-pabilities.

Superlative comfort whatever the conditions

The welcoming interior with its top-quality materials provides passengers with that feel-good atmosphere as only Mercedes knows how, with more than ample space for up to seven peo-ple. The GL-Class offers superb comfort on board - whether you’re just popping into town, cruising hundreds of kilometres or negotiating rough terrain. Occupants still enjoy good free-dom of movement even on the two full-sized individual seats in the third row of seats. The distance to the middle row of seats is 815 mm, with 979 mm headroom for passengers. If fewer seats are required, the rear individual seats can be stowed electrically at the push of a button, either individually or in tandem to pro-vide a completely flat load surface. The luggage compartment capacity amounts to 1240 litres in the five-seater version.

The GL-Class can provide up to 2300 litres of load capacity, with the load compartment measuring 2128 mm in length. In line with the wide range of applications handled by the versatile all-rounder, the THERMATIC automatic climate control system fitted as standard in the GL 320 CDI provides consistent temperature for all seven seats both in the depths of winter and on those sweltering summer days. The GL 500 comes with the standard-fit multi-zone THERMOTRONIC system, which offers even more cli-matic comfort. Other standard convenience and comfort ap-pointments include ARTICO man-made leather upholstery com-binations in the GL 320 CDI, electrically adjustable front seats and a fixed rear glass roof above the third row of seats.

Intelligent solutions promote excellent safety

The GL-Class makes full use of the advantages of its unitised body, combining optimum strength with intelligent lightweight steel design. The result is excellent passive safety. Combined with the front and rear deformation zones, the high-strength occupant cell forms an efficient base for the occupant protec-tion systems that include:

• Adaptive, two-stage airbags for the driver and front passenger
• Sidebags in the front, and in the middle row of seats as standard
• Windowbags across all three rows of seats from the A to the D-pillar
• NECK-PRO crash-responsive head restraints for the driver and front passenger as standard
• 3-point seat belts on all seven seats
• Seat-belt pre-tensioners and adaptive belt-force limiters for the driver and front passenger, seat-belt pre-tensioners and belt-force limiters on the outer seats in the middle row

PRE-SAFE® is standard, a world first in this market segment and Mercedes-Benz has raised safety to an even higher level. The sys-tem's most striking feature: passive and active safety systems are networked with each other. PRE-SAFE® utilises the sensors in the dynamic handling control systems such as ABS, BAS (Brake Assist) and ESP® and optimises the protective function of the passive safety components in potential accident situations. The GL-Class also takes the issue of pedestrian protection to a new level. The front section includes precisely defined ample crum-ple space between the body and the major assemblies under-neath. In conjunction with impact zones that are designed to yield, this design provides a high degree of protection both for pedestrians and cyclists.

The GL-Class meets all the requirements of a state-of-the-art, lux-ury SUV and even redefines them on a higher level. Yet the hallmark Mercedes off-roader genes such as superlative robust-ness, ruggedness and long-term durability have not been com-promised. It is not without reason that the model designation echoes the legendary precursor of all Mercedes-Benz off-road vehicles – the G-Class. Although not available for sale in Australia, the evergreen off-roader is now in its 27th year of production and will continue to be marketed alongside the new GL-Class.

Outstanding handling on and off-road

4MATIC – the permanent four-wheel drive from Mercedes-Benz – provides the GL-Class with superior handling whatever the con-ditions. Together with the standard-fit AIRMATIC air suspension, the precise speed-sensitive power steering and the ADS (Adap-tive Damper System) also fitted as standard, the imposing GL-Class (wheelbase 3075 mm) handles impressively. Handling, when pulling a trailer is no less impressive thanks to ESP® Trailer Stabilisation. It defuses critical driving situations involving a trailer before they become dangerous by precisely applying the brakes, while AIRMATIC provides fully automatic level adjust-ment.

Special off-road features such as Downhill Speed Regulation (DSR), hill-start assist and off-road ABS assist the GL-Class driver off road. The Off-Road Pro engineering package, standard on all GL models, means the GL-Class can also handle the most extreme off-road terrain. This includes a two-speed transfer case with a low range ratio and 100 percent differential locks for the trans-fer case and the rear axle. The modified AIRMATIC air suspension, designed specifically for the more demanding conditions, in-creases the ground clearance to a maximum of 307 millimetres where required, and raises the fording depth to 600 millimetres.

Majestic drive systems: new V6 and V8 engines

The ultra-modern engine line-up in all GL-Class models provides superlative drive comfort and compelling performance coupled with superior fuel consumption figures compared with other vehicles in the class. Alongside the 165-kW V6 diesel engine in the GL 320 CDI is the newly developed 5.5-litre, 285-kW engine in the GL 500. This engine was launched earlier this year in the new S-Class. Both engines also fulfil the stringent EU4 limits.

All GL-Class engine variants come with the 7G-TRONIC seven-speed automatic transmission with DIRECT SELECT as standard. Excellent performance and low fuel consumption result from the perfect combination of ultra-modern engines with 7G-TRONIC and the friction-optimised powertrain. Another important factor is the comparatively low gross vehicle weight thanks to the unitised body and the excellent aerodynamics (Cd 0.37) for such a large vehicle.

Success story from state-of-the-art production facilities

"Mercedes Quality – Made in the USA" has established itself as the company’s new trademark on the other side of the Atlantic and illustrates the success story of the DaimlerChrysler plant in Tuscaloosa/Alabama. The birthplace of the GL-Class started production in 1997 as the first Mercedes-Benz plant outside Europe. Around 600 million US dollars have been invested since 2001 in expanding and constantly modernising the plant; overall the company has invested around 1 billion US dollars. Following the extension of the Tuscaloosa plant in May 2005, its theoretical annual production capacity for all model se-ries stands at 160,000 units. The new GL-Class is now the third model series to be built here, alongside the M-Class and the R-Class.

Prices for the premium off-roader start at a competitive $103,900 for the entry level GL 320 CDI with the GL 500 priced at $146,900 (both exclude on-road costs).

Body, interior and climate control

Feel-good atmosphere in a class of its own

Attractive and impressive interior design, vast amounts of space, excellent seating ergonomics and automatic climate systems al-low up to seven occupants to travel in first-class comfort, whether on short trips about town, on long-distance tours or driving off-road. The upscale equipment and the strongly ap-pealing interior architecture, with its genuine wood trim and leather-upholstered dashboard, all help to create a typical Mer-cedes-Benz atmosphere of comfort and congeniality. At the same time a stiff, high-strength body structure provides a firm foundation not only for high standards of passive and active safety but also for comfort-enhancing low noise and vibration levels.

The external and internal dimensions shown below are a good indicator of the spaciousness offered by the new GL-Class. The corresponding figures for the R-Class are shown side-by-side for comparison:

-	GL-Class*	R-Class**
Length Width Height	5088 mm 1920 mm 1840 mm	4922 (5157) mm 1922 (1922) mm 1661 (1663) mm R 500
Wheelbase	3075 mm	2980 (3215) mm
Overhang front rear	870 mm 1143 mm	922 (922) mm 1020 (1020) mm
Distance between seats 1st/2nd row	880 mm	860 (920) mm
Distance between seats 2nd/3rd row	815 mm	780 (840) mm
Kneeroom in 2nd seat row in 3rd seat row	124 mm 21 mm	119 (153) mm 9 (25) mm
Headroom at front in 2nd seat row in 3rd seat row	1019 mm 1031 mm 979 mm	1010 (1010) mm 1014 (1027) mm 935 (946) mm
Shoulder room at front in 2nd seat row in 3rd seat row	1482 mm 1495 mm 1282 mm	1530 (1530) mm 1512 (1514) mm 1325 (1342) mm

* In seven-seater configuration ** Short-wheelbase version (long wheel-base)

As the comparison shows, the spaciousness of the GL-Class is comparable to the spaciousness offered by the R-Class's "dy-namic space concept". Occupant room in the third seat row is particularly good.

Electrically adjustable seats as standard

The GL-Class features electrically adjustable front seats and a manually adjustable multifunction steering wheel as standard. Extensive adjustment possibilities mean that occupants of all sizes can select an ergonomically optimal seating position. At the press of a button on the outer side of the seat cushion, the seats can be adjusted for fore-and-aft position, height, cushion angle and backrest angle. The driver's seat has a manually adjustable lumbar support. The head restraints are manually adjustable. Both front seats offer an excellent balance between good lateral support and superior springing and damping. One example: in the side bolsters, firmer foam plastic is used to provide good lateral support under heavy lateral acceleration, while in other areas a softer compound is used, to provide outstanding com-fort. The GL 500 is equipped as standard with electrically adjust-able seats with memory function and electrically adjustable steering column. Optionally, comfort can be taken even further, with multicontour seats (standard on GL 500). As an alternative to the standard "ARTICO" seat upholstery, leather or nappa leather upholstery is also available. On the top-of-the-line GL 500, nappa leather is standard.

Centre-row bench seat and third-row individual seats in rear

The centre-row bench seat with four-way backrest adjustment provides high seating comfort for up to three passengers. The wider section of the 1/3:2/3 split-folding seat has a folding arm-rest with cup holder and compartment. The backrests and the cushions can both be folded down, for transporting bulky loads: the divided seat cushion folds forwards in individual sections, then the backrests are folded forwards to create a flat surface level with the load floor at the rear. The outstanding loading dimensions of the GL-Class are shown below, again alongside the corresponding figures for the spacious six-seater R-Class:

	GL-Class*	R-Class**
Max. loading length up to front seats	2128 mm	1982 (2189) mm
Max. loading length up to centre bench seat	1309 mm	957 (1075) mm
Max. loading length up to third seat row	480 mm	347 (465) mm
Load compartment width min. max.	1027mm 1027mm	1130 (1130) mm 1246 (1246) mm
Max. load capacity***up to front seats loaded to roof loaded to top of seat back	2300 litres 1115 litres	1950 (2385) litres 1115 (1348) litres
Max. load capacity***up to centre seat bench loaded to roof loaded to top of seat back	1240 litres 750 litres	888 (1067) litres 550 (633) litres
Max. load capacity***up to third seat row loaded to roof loaded to top of seat back	300 litres 200 litres	324 (414) litres 244 (314) litres

* In seven-seater configuration ** Short-wheelbase version (long wheel-base)
*** VDA method

A newly developed EASY-ENTRY system provides convenient ac-cess to the optional third-row individual seats. To use this facil-ity, the narrower backrest section of the bench seat is released and folded forward together with the cushion. If the front pas-senger seat is in a further back position, it automatically slides forward. When the third-row passengers have taken their seats, the bench seat can be folded back into position and the front passenger seat returns to its original position.

When equipped with the third-row individual seats, the GL-Class is a full-size seven-seater. Either one or both seats can be electri-cally folded to create a continuously level load floor which, when the centre seat row is folded down as well, extends right the way through to the front seat backs. Customers who do not opt for the seven-seater version get an additional stowage com-partment under the load compartment floor. A fixed panoramic sunroof over the third-row seats, which is equipped with a sun-blind, provides additional comfort and enhances the sense of spaciousness. There are integral armrests in the sidewall trim and a cup holder is fitted on either side. The optional rear-seat entertainment system, comprising two colour monitors with headphone jacks in the back of the front head restraints and a CD/DVD player under the centre bench seat, allows rear-seat pas-sengers in the GL-Class to listen to or watch their own choice of music or films. To extend the entertainment programme even further, external audio/video sources or a games console can be connected to the system.

The proven EASY-PACK system makes for easier loading and unloading and secures the cargo. A load compartment cover and a safety net, which attaches behind the front seats or behind the centre bench seat are standard on all GL models, together with eight load-securing rings. Optionally, a hydraulically oper-ated tailgate with remote control can be supplied, or a floor-anchored EASY-PACK load-securing kit.

A pleasant climate and good entertainment

Since this adaptable and multi-talented vehicle is designed for very varied applications, the GL 320 CDI is equipped as standard with the THERMATIC automatic climate control system, to ensure that all seven occupants can enjoy a pleasant climate on board even in arctic cold or in tropical heat. The diesel models are equipped with a 1.7-kilowatt heater booster to provide quick warmth in cold weather. THERMATIC offers dual-zone tempera-ture control for driver and front passenger, a continuously vari-able fan speed and automatic variable air recirculation, for more effective cooling. The GL 500 is equipped as standard with the multi-zone THERMOTRONIC climate control system, which takes climate comfort to a new level, with separate temperature con-trols for passengers in the rear. The rear section is also equipped with its own booster. In conjunction with the multi-zone THER-MOTRONIC, a rear air conditioning unit (standard on GL 500) can also be supplied, for further enhanced cooling in the second and third seat rows.

A variety of audio systems offer highest standards of informa-tion, communication and entertainment. The Audio 20 radio with CD player, eight speakers, monochrome display and mobile phone pre-installation with telephone keypad is standard speci-fication. The top-of-the-line COMAND APS system with integrated radio, CD/DVD player, DVD navigation, telephone operation, col-our display and off-road menu is combinable with a TV tuner and a reversing camera. All audio systems can be upgraded to a Harmon Kardon LOGIC7 surround sound system which includes eleven speakers and a subwoofer to recreate a concert hall sound experience.

Body – long life and top-class aeroacoustics

A stiff body structure provides the basis for comfort-enhancing low noise and vibration levels in the GL-Class. Strength is maxi-mised by structural reinforcements which include an X-shaped underfloor reinforcement and a so-called "D" ring. At the rear, behind the large tailgate, the body ends in a hoop-type struc-ture resembling a fuselage bulkhead as used in aircraft produc-tion. This "D" ring connects the rear roof rail with the sidewalls and the floor structure, and provides significantly improved tor-sional stiffness and dimensional stability. At the body-in-white stage, 17 noise-insulating foam elements are installed in each sidewall. Further noise reduction is provided by careful sealing of all seams and flanges.

The low wind noise levels in the GL are unsurpassed in this class. Smooth airflow over the body, the optimised shape of the exte-rior mirrors, improved airflow around the A-pillar and the dou-ble or triple seals on the doors all help to reduce wind noise to a minimum. The windows play their part as well: the windscreen is 5 mm thick and the side windows 4.1 mm thick.

The fully galvanised body and further corrosion-proofing meas-ures such as cataphoretic immersion coating, cavity preserva-tion, seam sealing and localised use of steel panels with addi-tional coating in areas particularly at risk from corrosion help to ensure a long service life and maximum value retention. Further corrosion protection is provided by the six-part plastic underside panelling and a nano-particle clearcoat which is more scratch-proof than conventional paintwork and thus ideal for an off-road vehicle.

Active and passive safety

Safety first

Exemplary passive occupant protection and outstanding active safety give the GL Class a decisive edge. The high-performance off-roader makes full use of the advantages of its unitised body, combining optimum strength with intelligent lightweight steel design. The result is excellent passive safety. Combined with the front and rear deformation zones, the high-strength occupant cell forms an efficient base for the occupant protection systems, meaning that the GL-Class has the potential to achieve maximum ratings in both US and European NCAP crash tests.

World premiere: PRE-SAFE® makes its debut in this vehicle category

The luxurious off-roader is the world's first seven-seater to fea-ture the innovative PRE-SAFE® preventive occupant protection system, available as standard. The most striking aspect of the system, first introduced by Mercedes-Benz in the S-Class in 2002, is the fact that the active and passive safety systems are net-worked with each other. PRE-SAFE® utilises the sensors in the dy-namic handling control systems such as ABS, BAS (Brake Assist) and ESP® (Electronic Stability Program) and diagnoses critical han-dling situations which can potentially lead to an accident. This is the case when Brake Assist is activated during emergency brak-ing situations or when, despite the intervention of ESP®, it is no longer possible to stabilise the vehicle, since this is beyond the bounds of physical possibility. If such a situation is detected – this detection takes place within a matter of milliseconds – the system optimises the level of protection provided by the passive safety components and prepares the occupants and the vehicle for a possible collision. If necessary, the driver and front-passenger seat belts are tensioned whilst the optionally available (standard on GL 500), electrically adjustable front-passenger seat with memory function is moved into an optimal position to al-low the airbags and seat-belt system to deploy to maximum ef-fect. In addition, the system closes the sliding sunroof and side windows as a precaution. If the collision is avoided and the dy-namic handling limits are not reached, the seat-belt tensioners are released automatically. The front-passenger seat, side win-dows and sliding sunroof can then be returned to their original positions.

Outstanding passive safety for seven occupants

People travelling in the GL-Class are protected by a comprehen-sive restraint system which, as well as the PRE-SAFE® components described above, also includes the following features:

• Adaptive airbags for the driver and front passen-ger
• Sidebags for the driver and front passenger and for the middle row of seats as standard
• Windowbags across all three rows of seats
• 3-point inertia-reel seat belts on all seats (front seat belts are height adjustable), with seat-belt tensioners and adaptive belt-force limiters (outer seats in the middle row and rear seats have seat-belt tensioners and belt-force limiters)
• NECK-PRO crash-responsive head restraints for the driver and front passenger as standard
• Passive knee-protection system
• Seat occupancy sensor on the front-passenger side, includ-ing weight sensor in certain countries
• Electronic airbag control unit with special crash sen-sors
• Roll-over sensor

One of the key safety components is the electronic control unit which activates the restraint systems based on signals received from a sophisticated sensor system, including the central crash sensor on the vertical axis of the vehicle, two additional up-front sensors in the radiator cross-member, two lateral accelerome-ters below the B-pillar and two satellite pressure sensors in the front doors. The rear doors are also equipped with satellite pres-sure sensors.

Thanks to this extensive sensor system and the calculations that are performed centrally within a matter of milliseconds, the air-bags and seat-belt systems are able to provide far more effec-tive occupant protection. If the up-front sensors detect a frontal collision, for example, the new crash sensors compare the re-ceived data with the data provided by the central crash sensor on the centre tunnel and, if the impact is deemed severe enough, trigger the front airbags and the seat-belt tensioners. Since the up-front sensors detect the impact at an earlier stage, the airbags and seat-belt tensioners can be activated sooner. This configuration has major advantages. After all it still holds true that the earlier the occupants take part in the vehicle's overall deceleration, the higher the level of protection that can potentially be provided by the restraint systems. But the crash sensors do far more than this. If the system detects an accident of moderate severity, only the first stage of the adaptive airbags is deployed. However, if the impact is more severe, the second stage of the airbag is also fired after a slight delay. This means that the driver and front-passenger airbag can provide the op-timal degree of protection for a wide range of impact scenarios.

The sophisticated sensor system also supports the activation of windowbags and side airbags. In this case the data provided by the central crash sensor are compared with the lateral accelera-tion data recorded by the side sensors below the B-pillar and the information sent by the pressure sensors in the doors. Based on these data, the system control then calculates the optimal acti-vation strategy within a matter of milliseconds. In addition, the command centre has access to a roll-over sensor. In certain roll-over situations, all the belt tensioners and both windowbags are activated. The windowbag itself has a special coating and is filled by a helium gas generator, thus ensuring a longer service life and, as a consequence, a higher level of occupant protection.

The crash sensors also control NECK-PRO crash-responsive head restraints. If the system detects a rear impact of sufficient sever-ity, it activates the head restraints, which provide support for the heads of the driver and front passenger at an earlier stage and reduce the risk of upper spinal column injuries.

Unitised body with high protection potential

Having dispensed with the frame-type design that is more usual in this vehicle category in favour of a unitised steel body, the Mercedes-Benz development engineers were faced with a new challenge. On the one hand, the vehicle had to retain the typical benefits of a frame-type design such as robustness and durabil-ity under tough off-road conditions. On the other hand, the specifications book also called for a relatively lightweight design and outstanding passive protection potential on a par with Mer-cedes-Benz saloon cars. The engineers were able to surmount this challenge through intelligent use of high-strength steels and a clever lightweight steel design. Some 54 per cent of the GL bodywork is made from high-strength steel. Even thermo-formed ultra-high-strength steel was used in some areas.

The unitised steel body forms the ideal base for the passive oc-cupant protection systems. An extremely robust passenger cell surrounds the occupants like a protective cocoon. Its basis is a three-piece floor assembly with a centre section made of thicker material which forms a sturdy backbone. This central assembly is further stiffened by a thick-walled, X-shaped tunnel reinforce-ment. Lateral stability and, therefore, the survival space in the event of a side collision, is assured by side members in the front seating area and a central seat cross-member that has been rein-forced using thermoformed ultra-high-strength steel. In addi-tion, a robust diagonal member is used to strengthen the body from the firewall to the point of intersection between the side member and the B-pillar. A tubular cross-member, which also serves as a load-bearing structure for the dashboard, is bolted to the two A-pillars, the tunnel, a structural reinforcement below the windscreen and the firewall, making the front of the pas-senger cell even more rigid.

The extremely sturdy side section of the body essentially com-prises two components, namely the inner side wall and the outer side wall. Overall stiffness and rigidity are determined by structures including:

• Triple-shell A, B, C and D-pillars
• The side member
• The partially double-walled high-strength roof frame
• The external panelling with an additional reinforcement frame.

Like the rear seat cross-member, the A and B-pillars have rein-forced areas made from thermoformed ultra-high-strength steel.

The rear area incorporating the third row of seats is de-signed to provide the highest possible level of protection for the rear passengers in the event of a rear impact. The design of the rear side members is based on a continuous closed cross-section and graduated material thicknesses. By adopting this approach, the designers were able to ensure greater solidity whilst also enhancing energy absorption and improving defor-mation behaviour. Further rigidity is provided by the recess for the spare wheel and an equally high-strength, solid cross-member that also serves as a load-bearing structure for the indi-vidual seats in the rear.

The front and rear ends, by contrast, are designed to absorb as much impact energy as possible in the event of a collision. The impact-absorbing front-end structure consists of the two longi-tudinal members, which are reinforced by two shells on the in-side, and two longitudinally-aligned members on the outside, which are braced by the A-pillars in the event of a crash. If an offset crash occurs, the solid firewall cross-member below the cowl has an important role to play in that it distributes the im-pact forces to the side of the vehicle not involved in the impact, thus improving energy absorption. The bolted front end forms the front cross-member which also transfers impact energy to the side of the vehicle not involved in the impact in the event of an offset frontal crash. It consists of a two-shell sheet-steel struc-ture, which houses the headlamp units, a two-shell radiator cross-member, a flexible aluminium member and two crash boxes which deform in order to absorb all of the impact energy at impact speeds of up to 15 km/h. These boxes are easily re-placed, thus simplifying accident repairs. Repairs are also made easier by the fact that the front-end components are bolted to-gether. Like the front end, the rear section also features a flexi-ble aluminium member which is bolted to the rear structure by means of two steel crash boxes.

Together with the steering gear and the engine/transmission as-sembly, the front axle is mounted on an extremely stiff sub-frame which is connected to the body by means of four rubber mounts. Just like the rear axle subframe, it deforms in order to absorb impact energy in the event of a collision. To further im-prove durability under the toughest of driving conditions, the bodywork engineers have strengthened the subframe mount-ings in specific areas. The triple connection points ensure a reli-able and durable connection, even during continuous operation under tough off-road conditions.

Active safety for all conditions

Whereas the passive safety systems ensure the highest possible level of occupant protection during and after an accident, the active safety features play a preventive role. Key aspects which contribute to the high degree of active safety provided by the GL-Class include an outstanding level of driver-fitness safety and exceptional ergonomic design as well as a comfort-oriented chassis offering excellent directional stability, precise speed-sensitive power steering, high-performance brakes and, last but not least, the sophisticated 4MATIC all-wheel drive system. Stan-dard-fit dynamic handling control systems such as ESP®, the 4ETS traction control system developed especially for all-wheel drive, ABS and Brake Assist (BAS) further optimise the level of active safety, as do the standard-fit AIRMATIC air suspension and the Adaptive Damping System (ADS). Active safety is additionally en-hanced by powerful headlamps and the adaptive brake lights.

The latest version of the tried-and-trusted Electronic Stability Program (ESP®) includes additional components such as ESP® Trailer Stabilisation and a tyre pressure loss warning system. The ESP® Trailer Stabilisation defuses critical driving situations involv-ing a trailer before they become dangerous by applying individ-ual wheel brakes as required. Alongside ESP® Trailer Stabilisation, the extremely rigid body, the automatic level control feature of the AIRMATIC system, the 4MATIC all-wheel drive system and the long wheelbase length ensure safe and reliable handling when towing, even in adverse conditions such as crosswinds or when the road surface has ruts caused by heavy trucks. As is the case during normal operation, Brake Assist (BAS) and the tyre pres-sure loss warning system have a positive effect, warning the driver if one or more tyres loses pressure by flashing up an un-ambiguous "Tyre pressure – check tyres" message on the central display.

The high-performance lights, including H7 projection-beam headlamps and fog lamps, relieve driver stress when driving in twilight, in the dark or in fog. Bi-xenon headlamps with the Ac-tive Light System and a cornering light function, available as an optional extra on the GL 320 CDI (standard on GL 500), further enhance visibility.

Drive system and chassis

Top performance whatever the conditions

High-torque, combustion-optimised drive units and a chassis that delivers outstanding handling and exceptional ride comfort whatever the conditions make the GL-Class as highly impressive on-road as it is off-road.

The engine line-up features four state-of-the-art powerplants that play a key role in enhancing driving enjoyment thanks to their harmonious torque and power delivery. The direct-injection diesel engine in the GL 320 CDI complies with the latest EU 4 emission standards. The tried-and-trusted V6 diesel unit in the GL 320 CDI model has an output of 165 kW and an impressive peak torque of 510 Nm, which is available across a broad engine speed range. The result is a highly respectable set of perform-ance figures: the GL 320 CDI accelerates from 0 to 100 km/h in 9.5 seconds, reaches a top speed of 210 km/h and consumes a mere 9.7 l per 100 km.

In addition to the V6 turbo diesel GL 320 CDI, the GL 500 is even keener to provide power when requested to do so, accelerating from 0 to 100 km/h in 6.6 seconds, which is almost in sports car territory. The same can be said for the top speed of 210 km/h. Yet the GL 500 still returns a highly impressive fuel consumption figure of 13.8 l per 100 km, especially given that its kerb weight is 2,445 kg.

Technical highlights of the new V8 aluminium engines include four valves per cylinder, with continuous intake and exhaust camshaft adjustment, and an intake bridge with variable intake manifold. In contrast to conventional systems, in which only the length of the entire intake tract is varied in order to optimise the power output, the module here switches cylinder-selectively. Further cylinder-selective components used include electropneumatically driven tumble flaps which increase the flow speed in the partial-load range and therefore improve tumbling of the fuel/air mixture in the combustion chamber. As a result, combustion is improved considerably whilst power output is also boosted. As well as focusing on higher engine output and a reduction in exhaust emissions and fuel consump-tion, development work centred on improving comfort levels. The powerplant engineers optimised both engine refinement and the noise levels by modifying the crankshaft bearings, for example. The widened crankshaft bearing shells are no longer fixed by individual bearing brackets in the engine block but by one rigid mounting plate per cylinder bank. This cross-bolting technique also makes the entire engine block sturdier. The cyl-inder head cover with integrated camshaft bearings has a similar stabilising effect. Further measures implemented to enhance comfort include the use of lightweight pistons and conrods, which reduce the moved masses and therefore vibrations, and the installation of larger engine mounts to connect the engine to the subframe. Both engines undercut the stringent EU 4 emission limits (LEV II standard in the US).

Thermal optimisation as a result of extensive computer simula-tions

Thermal protection of the vehicle is proving an increasingly stiff challenge for engineers because of a conflict of aims. On the one hand the engine, transmission and auxiliary units require a suffi-cient supply of air in order to ensure thermal operational reli-ability at all times, even under the toughest of conditions. On the other hand experts in the field of acoustics and aerodynam-ics insist on encapsulating the engine as much as possible. There is also the high level of additional equipment to consider. After all, more and more auxiliary units are being installed in the en-gine compartment. One solution that ensures a high level of thermal protection is the use of detailed computer simulations to supplement extensive field testing.

Firstly the entire engine chamber, including all units, and the surrounding body, including all cooling air apertures, is simu-lated based on CAD data. Secondly further parameters such as the potential surface temperatures and dissipation energies of all components are added. Then the system "tests" the GL-Class specification concerned and simulates extremely demanding driving conditions, including prolonged periods of motorway driving under full load and driving across steep mountain passes with a trailer attached at high outside temperatures. The de-tailed simulation data enable the engineers to precisely calculate through-flow in the engine compartment and, therefore, the flow to all the components and assemblies.

Based on the data obtained, specific measures are implemented to combat any hot spots and to ensure effective cooling of all components under all operating conditions. The temperature experts can therefore propose additional or modified cooling air apertures, the relocation of certain components or the installa-tion of heat dissipation panels, for example. All of these meas-ures can then be verified by carrying out extensive field testing.

4MATIC permanent all-wheel drive and seven-speed automatic transmission

4MATIC – the permanent all-wheel-drive system from Mercedes-Benz – works together with the powerful engines and 7G-TRONIC seven-speed automatic transmission installed in the GL-Class to provide outstanding handling whatever the conditions. All-wheel drive is provided by a two-stage transfer case with reduc-tion gearing, which is flange-mounted directly onto the 7G-TRONIC automatic transmission. Two propshafts with constant-velocity joints normally distribute the drive torque evenly be-tween the front and rear axle, while a bevel-gear differential takes care of any differences in the rotation speed. In the event of different rotation speeds at the individual wheels, due to traction slip, the 4ETS traction system intervenes to vary the torque distribution. In this case, the torque is sent to the wheels offering the best traction by braking the spinning wheel(s).

The 7G-TRONIC seven-speed automatic transmission is operated using a control lever. Alternatively, shift buttons on the back of the steering wheel can be used to select the gears manually. Op-tions available for making the driver's life easier include the DIS-TRONIC radar-based proximity control and cruise control system which detects vehicles ahead and maintains a set safety distance automatically.

Superlative on-road handling

One of the main aims when designing the chassis was to ensure that the excellent off-road pedigree of the GL-Class did not in-fringe upon its on-road performance in any way. The chassis en-gineers at the Mercedes Technology Center (MTC) successfully achieved this objective. Despite a kerb weight of around 2400 kg, the high payload, a wheelbase of 3075 mm and a vehicle length of 5088 mm, the handling agility and manoeuvrability are on a par with those of far more compact and lightweight cars. The double-wishbone front suspension, including anti-dive con-trol and a stabiliser bar, is connected to the body by means of a rubber-mounted subframe. Thanks to this vibrational decoup-ling and the high position of the upper control arm, the double-wishbone front suspension, or "high-link axle" ensures excep-tionally low road noise and tyre vibration as well as outstanding handling. A subframe is also used to connect the body to the four-link rear axle which has a lower wishbone, an upper link level with a supporting strut and a leading/trailing link as well as a track rod at wheel centre. By virtue of its design, the direc-tionally stable axle features both anti-squat control and anti-dive control. The agile and sure handling is also down to the speed-sensitive power steering. At higher speeds, there is less steering assistance for the driver, resulting in better road feel. At lower speeds, for example when manoeuvring or parking, the steering is very light.

AIRMATIC and the Adaptive Damping System as standard

One of the most impressive standard features of the new GL-Class is the multi-talented AIRMATIC air suspension which pro-vides outstanding on-road comfort and substantially enhanced directional stability. AIRMATIC compensates for variations in the vehicle load and driving conditions and also functions as a level control system. Away from the road, the full air suspension sys-tem enhances the vehicle's off-road capability by providing ad-ditional ride heights.

The body can be raised or lowered at any time, either automati-cally or at the request of the driver, whilst the engine is running. The system is speed-sensitive, automatically lowering the body by 15 mm at both axles when the speedometer needle reaches 140 km/h, thus reducing aerodynamic drag and improving direc-tional stability. Once the speed drops back below 40 km/h, the body is raised to the normal level again. An overview of the dif-ferent levels:

Level designation	AIRMATIC setting	Ground clearance
Highway	Basic level	197 mm
High speed	Lowered by 15 mm	182 mm
Off Road 1	Raised by 30 mm	227 mm
Off Road 2	Raised by 80 mm	277 mm
Off Road 3	Raised by 110 mm	307 mm

In the standard specification, AIRMATIC works in tandem with the ADS Adaptive Damping System which adjusts the damping rates according to requirements, depending on the road condi-tions, driving style and vehicle load. Switchable solenoid valves in the gas-filled dampers allow the compression and rebound stage to be adjusted for each wheel in line with the situation in hand. Depending on the control command, the valves can set one of four characteristics within an extremely short time (less than 0.05 seconds):

• Stage 1: soft compression and rebound stage, comfortable road/tyre contact with little body movement and low acceleration values
• Stage 2: skyhook mode – soft rebound setting and, at the same time, hard compression stage
• Stage 3: skyhook mode – soft compression setting and, at the same time, hard rebound damping
• Stage 4:hard compression and rebound setting to reduce variations in wheel load when cornering at speed or braking or in the event of high longitudinal and transverse ac-celeration

If the body speed exceeds a certain level, the system constantly switches between the second and third damping stage based on the skyhook algorithm, thus effectively compensating for the rolling and pitching motion of the body. The current driving situation is detected by means of a steering angle sensor, three acceleration sensors on the body, the speedo signal, the ESP® data and the brake pedal switch signal. Based on this informa-tion, the electronic control unit determines the best damping force in each case and selects the corresponding damper charac-teristics. In addition, the driver can influence the switching points and spring rates at the push of a button on the centre console, which enables "Auto", "Sport" or "Comfort" mode to be selected. At the front axle of the new GL Class, the adjustable ADS gas-pressure shock absorbers and the air springs are inte-grated in a spring strut. At the rear axle, the ADS shock absorber is located behind the air spring. In addition, torsion-bar stabilis-ers are fitted at the front and rear.

Powerful brakes

The new GL-Class features large, internally ventilated disc brakes with sliding callipers at both the front axle and the rear axle. At-tributes of the brake system include excellent response, high re-sistance to fading and a long service life. The brake data at a glance:

	GL 500	GL 320 CDI
Front axle Brake piston diameter Brake disc diameter x thickness	2 x 44 mm 375 x 32 mm Internally ventilated	2 x 44 mm 350 x 32 mm Internally ventilated
Rear axle Brake piston diameter Brake disc diameter x thickness	42 mm 330 x 22 mm Internally ventilated	42 mm 330 x 22 mm Internally ventilated

Wide-base tyres and 18- to 20-inch light-alloy wheels emphasise the impressively confident appearance of the new GL-Class. Standard equipment for the six-cylinder GL 320 CDI model in-cludes 5-spoke light-alloy wheels with 265/60 R 18 tyres. The eight-cylinder GL 500 model comes with 19 inch 5-twin-spoke light-alloy wheels and 275/55 R 19 tyres. Options available for all GL-Class variants include five-spoke 8.5 J x 20 wheels with 275/50 R 20 tyres.

When the going gets rough: the OFF-ROAD PRO engineering package

While the GL-Class cuts a fine figure on the road, its performance off the road is equally impressive. The modified AIRMATIC system permits a ground clearance of 307 mm in the highest off-road mode, in which case the fording depth is 600 mm. Should the ground clearance on occasion prove insufficient, a steel under-guard protects the important chassis and powertrain compo-nents. The off-road data at a glance:

Ground clearance	307 mm
Overhang, front / rear	870/1143 mm
Angle of approach/ departure	33/27 degrees
Ramp angle	23 degrees
Fording depth	600 mm
Slope-climbing ability	100 percent
Tilt angle	35 degrees
Turning circle	12.1 m

The standard-fit OFF-ROAD PRO engineering package extends the range of options for negotiating normally impassable terrain considerably. Thanks to the transfer case reduction gearing (2.93: 1) and multiple-disc locks with up to 100% locking at the reinforced rear axle and in the centre differential, almost all off-road terrain becomes passable. The traction-control measures are backed up by the 4ETS traction control system which in-creases the drive torque at the wheels offering good grip by braking the wheels providing less traction, thus enabling head-way to be made even under the toughest of driving conditions. The front axle is also equipped with an "electronic" differential lock which, in contrast to mechanical locks, ensures that the ve-hicle remains fully steerable.

In addition to 4 ETS, there are further electronic dynamic han-dling control systems which help to make the driver's job easier when negotiating difficult terrain.

• The off-road ABS system, specially optimised for rough terrain, shortens braking distances on poor surfaces, loose ground or extremely steep descents by allowing the wheels to lock under certain circumstances
• Downhill Speed Regulation (DSR) allows the driver to select various maximum speeds which the GL-Class will not exceed when negotiating steep descents, for example
• Hill-start assist prevents the vehicle rolling away when start-ing off on an uphill or downhill slope
• When the accelerator is pressed, the throttle valve opens more slowly, thus improving controllability
• Manual operation of the 7G-TRONIC using the steering-wheel shift buttons. The selected gears are retained for longer, de-pending on the permitted engine speeds.

Two rotary controls on the centre console allow the driver to se-lect from the drive modes and AIRMATIC modes, details of which are permanently visible on the central information display.

Design

A symbol of muscular power and prestige

The appearance of the new GL-Class leaves observers in no doubt whatsoever as to the strong character of the luxurious Sport Utility Vehicle: the premium off-roader from Mercedes-Benz displays size, robustness and muscular power in abundance as well as being sporty and dynamic in character. Despite a typically off-road body with short overhangs, its own, vibrant personality shines through.

This effect is thanks in no small part to an extremely linear de-sign that is without superfluous flourishes yet displays remark-able finesse. Large surfaces and clearly defined, powerful lines create distinctive contours and visually emphasise the robustness and sheer athleticism at the heart of the GL-Class. The roof rails, wheels and exterior mirrors are generously proportioned and enhance the powerful appearance. At the same time, a closer inspection reveals finely drawn, sinewy lines that add to the extraordinary appeal of the new Mercedes off-roader, giving it a highly prestigious feel. This is a luxury vehicle with backbone and noblesse.

Front end with a no-nonsense character

The front-end design also emphasises the solid nature of the new GL-Glass. A steeply angled, robust radiator grille with a cen-trally positioned star dominates the front view. Two particularly powerful transverse louvres in silver with broad chrome high-lights lend the vehicle a muscular look. The backdrop here is provided by a black honeycomb structure which is echoed in the air intake opening below the bumper.

The high bonnet, a classic off-road feature, has two powerdomes running along its length. Sharply defined ridges delineate the bonnet on the left and right and form an unusually distinctive link between the bonnet and headlamps, evoking the image of an athletic, chiselled musculature.

The wide clear-lens headlamps together with the clearly struc-tured halogen projection-beam technology form a high-quality light unit. The fog lamps (with the cornering light function if this option is ordered) are housed in the bumper in a separate, extremely solid frame whose robust design is emphasised by two horizontal fins. The standard-version light units are ringed in black. If the cornering light function is specified, they have chrome surrounds.

The upper part of the bumper is painted in body colour, while the section below this is trimmed in dark grey. This horizontal colour contrast makes the off-roader appear lighter and sleeker. A chrome-look underride guard, available as an optional extra, reinforces this impression.

Silhouette: elegance and durability

From the side, it is clear that the GL-Class offers ample space. There is an overriding impression of length. The long wheelbase and a high roof line which extends as far as the rear wall create a dynamic silhouette. Large window areas emphasise these lines, further adding to the air of elegance whilst also ensuring excel-lent visibility and a bright interior atmosphere. By way of con-trast, the upright D-pillar is in keeping with the off-road charac-ter and solidity of the vehicle and serves to underline its de-pendability in any situation.

Dynamic side lines, which make the vehicle appear longer whilst also emphasising its strong, solid character, are testament to a meticulously thought-out design. A crease line emerges from the headlamp surround and runs smoothly along the front wing, across the A-pillar and the side roof frame before reaching the tailgate. Most prominent of all is the waistline which emanates ahead of the front wheel arch, rises rearwards and reaches its conclusion at a point above the tail lights. Beneath this is a fur-ther crease line stretching from the front wing, across the doors and as far as the D-pillar.

Generously-sized rub strips add structure to the side surfaces and, together with the solid roof rails in black, create a sporty, prestigious appearance.

The powerfully accentuated wings with broad chamfered edges and the large light-alloy wheels with robustly dimensioned spokes lend the vehicle a firm-looking stance.

Distinctive rear end

The high rear end is divided by horizontal crease lines which emphasise the width of the vehicle and reduce the impression of height. This effect is reinforced by the raised position of the sturdy rear bumper, the high-quality chrome handle in the tail-gate and the chromed rectangular tailpipes occupying a wide position on each side of the rear end.

The impressive tail lights feature a new take on the classic Mer-cedes-Benz "ribbed lenses" theme. Ribbed areas and smooth surfaces alternate whilst two wide highlights, which are themselves subdivided by chrome highlights, appear to split the tail lights.

The reflectors have been removed from the main light unit and are now arranged separately in the bumper below the loading sill. The third brake light has been located in the roof spoiler.

Optional extras include a stainless-steel scratch guard on the bumper loading sill as well as a chrome-look stainless-steel un-derride guard similar to the one fitted at the front end.

High-grade interior materials

The interior is dominated by high-quality materials displaying handcrafted precision and attention to detail, creating a luxuri-ous, tasteful ambience which embraces the special character of an off-roader in many respects. The smooth dashboard and door surfaces underline robustness and self-assurance, whilst the col-our contrast between the darker upper section and the lighter lower section as well as the continuous wood trim elements lend the interior a sense of breadth and spaciousness.

Drivers of the new GL-Class sit behind a four-spoke multifunction steering wheel featuring aluminium-style lower spokes. Behind this is the upper section of the dashboard, also trimmed in leather, rising in a powerful arch that spans the instrument clus-ters. The instruments are housed in two slanting tubes, making them easy to read and giving them a sporty appearance. Fine chrome rings surrounding the tubes add a further touch of elegance.

The console in the centre of the dashboard features a clearly de-fined, smooth design and houses easy-to-reach, logically positioned control and display functions. Here the emphasis is firmly on perfect ergonomics and tangible precision. Adjoining this area is the sturdy centre console with stowage compartments and integral cup holder functions as well as two robust, longitu-dinally arranged grab handles which echo the lines of the trim strips in the doors and provide useful support points when driving off-road.

The door centre panels and the armrests are padded and feature an elegant trim as well as distinctive topstitching. Once again, wood trim elements catch the eye. There is a choice between bird's-eye poplar, burr walnut with chrome trim strips or pale birch with chrome trim strips.

Colours and paints

The new GL-Class comes with a choice of three interior appoint-ments colours: black, alpaca grey or cashmere beige. These can be combined with two non-metallic and nine metallic paint finishes.
