1. The new BMW 1 Series – Overview
2004 will go down as a memorable year for BMW as a new chapter begins in the
company’s history. Not only has the year seen the return of the 6 Series, but it
also saw the company continue targeting profitable new niches with the launch of
the X3. Continuing the success is the arrival of a brand new BMW to a vital
market segment – the BMW 1 Series.
Introducing BMW’s ‘Ultimate Driving Machine’ credentials to a new, broader
marketplace, the 1 Series offers drivers the unique proposition of a
front-engine, rear-wheel drive car with the practical day-to-day benefits of a
compact hatchback. This potent combination sets it apart from class rivals,
providing unsurpassed handling and ride through its near 50:50 weight
distribution. Power directed to the rear wheels maintains optimum grip leaving
the front wheels to steer. The result? Best in class driving dynamics and a BMW
that will attract a whole new group of buyers to the brand.
Being launched on 02 October, the BMW 1 Series comes with five doors, three
engines, but just one aim – to set a new standard for its class through unique
BMW design and engineering solutions.

Concept
The new BMW 1 Series brings a new dimension in driving
pleasure to Australian motorists, combining for the first time the functionality
of a smaller five-door with traditional BMW values of driving dynamics, safety,
comfort, quality and innovation.
With this new model BMW has transferred its core DNA to a new vehicle segment
to create both a smaller car and a true BMW.
Market analysts observed a remarkable growth potential within the premium
compact segment for a vehicle combining a high level of functionality and
enhanced comfort and safety with the distinctive character and driving
satisfaction of a BMW.
Until now, consumers seeking these values were made to compromise. However,
with the new BMW 1 Series, drivers who expect more than was previously available
have the opportunity to become acquainted with the typical qualities of the BMW
brand right down to the smallest detail.
Design
The BMW 1 Series might be an all-new model in the company’s
line-up, but the heritage of the marque shines through. Unmistakable BMW
features such as the double headlights, kidney grille and Hofmeister kink are
all present. Sitting on a wheelbase of 2,660mm and with short overhangs, 737mm
front and 830mm rear, the 1 Series has an air of the BMW Z4 and historic M
Roadster about it. The striking lines also cut a swathe through the air with the
aerodynamic body of the 1 Series helping to post a drag co-efficient of 0.31.
Visually its dimensions and styling are almost coupé-like, but internally the
car is capacious with the height from the seat base to the roof lining measuring
963mm in the front and 967mm in the rear, providing ample headroom for tall
passengers. Furthermore, the 1 Series offers occupants class-leading shoulder
and elbow room for greater comfort. Another clear benefit of the front-engine,
rear-drive layout is that the driver will also appreciate accelerator, brake and
clutch pedals that are centrally located and not offset compared to its
front-wheel drive competitors.
Sharing technology with the larger models, the 1 Series can be specified with
iDrive, including Professional or Business navigation systems, front and rear
Park Distance Control with pictogram, Bluetooth telephone connectivity and Xenon
headlamps.
A distinct reference to the car’s sporting aspirations sits on the dashboard,
with its standard Z8-style starter button. Pressing the button after inserting
the new-style key fires up the technologically advanced four-cylinder engines.
The newly-designed key retains the advanced Key Memory feature common to all
BMWs. Courtesy of a microchip located inside the key, the 1 Series recognises
which of the two keys supplied with the car is being used and alters door
mirrors, air conditioning, radio and electric seat settings accordingly.
Further personalisation is possible, with the owner able to specify the
interior in either fabric upholstery or optional leather. Optional on the 118i
and standard on the 120i, optional sport seats, derived from those in the M3
which provide the 1 Series driver with the ability to adjust the side bolsters
for optimum lateral support. Again, further recognition of the 1 Series as a
driver’s car. In the rear, boot capacity is 330-litres with the seats raised and
with the rear seats spilt 60:40, the virtually flat load floor offers 1,150
litres of storage space.
Chassis and suspension
The BMW 1 Series is unique in its class with
its front engine - rear drive layout offering near perfect 50:50 weight
distribution, resulting in dynamic on-road capability. Unlike its competitors
who transmit power and steering input through the same two wheels, the 1 Series
leaves the front wheels to guide the car while the power is transmitted to the
rear. This ensures improved grip and better traction under acceleration as the
weight of the car transfers to the rear.
Once on the move, the rear-wheel drive 1 Series comes into its own, with the
steering remaining uncorrupted and the car delivering a sports car-type driving
experience. It is no coincidence that all serious racing cars are rear-wheel
drive.
But sporty and dynamic handling can be compromised by weight. Thanks to the
car’s svelte 1,230kgs overall weight (118i), delivered through the use of
aluminium parts, the 1 Series delivers on its promises. Much of the front
suspension and subframe are made of aluminium along with the axle, suspension
struts and pivot bearings. At the rear, BMW’s pioneering five-link rear
suspension is fitted for optimum ride quality. By replacing the traditional
double wishbone arrangement with a version of the five-link set-up employed on
the 5 and 6 Series, engineers have been able to subtly alter the toe-in, toe-out
and camber angles for increased cornering ability.
For drivers wanting an even sportier ride, the new BMW 1 Series can be
specified with sport suspension that lowers the car by a further 15mm. This not
only gives the car a more aggressive stance but also adds to the performance
characteristics by giving a more agile ride.
Transferring the chassis abilities and engine performance to the road is the
responsibility of the car’s Run-flat tyres. The 1 Series comes as standard with
16-inch wheels and Run-flat tyres, banishing roadside tyre changes to history.
For those wanting to personalise their car, a variety of optional 16 or 17-inch
alloy wheel designs are available as factory-fit or dealer-fit accessories.
Engine and transmission
The new BMW 1 Series’ chassis and
rear-wheel drive layout are mated to two advanced and flexible engines.
The 110 kW BMW 120i is the largest petrol engine and features both double
VANOS and VALVETRONIC variable valve control for increased engine efficiency and
performance. A capacity of 1,995cc produces 200Nm of torque at 3,600rpm, a zero
to 100 km/h time of 8.7 seconds and a top speed of 217 km/h. Even with these
levels of performance, fuel consumption is a frugal 7.4 litres / 100km based on
the combined EU cycle. When compared to its competitors, the 120i offers
best-in-class acceleration, top speed, economy and emissions.
With 95 kW extracted from its two litre engine, the BMW 118i possesses the
same technical attributes as the 120i. It also features a double VANOS and
VALVETRONIC engine. It accelerates from zero to 100 km/h in 9.4 seconds and has
a top speed of 208 km/h. Fuel consumption for this model, based on the combined
EU cycle is just 7.3 litres / 100km.
Whatever the choice of engine, a precise, short throw gearshift makes for
quick and effortless changes. The BMW 118i has a five-speed manual gearbox,
while the 120i has a six-speed manual gearbox as standard. Both can also be
specified with a six-speed automatic gearbox featuring Adaptive Gearbox System
and Steptronic manual gear selection.
Safety
The new BMW 1 Series comes as standard with the highest
levels of active and passive safety. Familiar systems from other BMW models such
as ABS brakes, Dynamic Stability Control, Dynamic Traction Control, Dynamic
Brake Control and Cornering Brake Control are all fitted as standard. BMW’s Tyre
Puncture Warning System is also fitted, alerting the driver to the possibility
of a loss in pressure, while the standard Run-flat tyres ensure the car can be
driven safely for up to 200km at up to 80 km/h with all tyres punctured.
Another safety feature on the 1 Series is the recently introduced Brake Force
Display (BFD).
Using a double segment of lights in the rear light cluster, BFD increases the
brake light illumination area as soon as the ABS system is activated or the car
detects a rapid deceleration. The extra illumination warns drivers behind that
the car is braking sharply.
Should the worst happen and an accident occurs, sensors in the Advanced
Safety Electronics system cut the fuel pump and alternator, and the battery is
deactivated to minimise the risk of fire. Six airbags are standard in the 1
Series with the two front airbags intelligent, dual-stage versions that inflate
in speed and size depending on the severity of the accident and work in
conjunction with the active seatbelt tensioners. Front side airbags are located
in the side of the front seat and AHPS head airbag system protects both front
and rear passengers. To protect the smaller passengers, two ISOFIX child seat
restraints in the rear are available across the 1 Series range.

2. Concept
A new dimension in smaller than 3 Series motoring
The new BMW 1
Series brings a new dimension in driving pleasure to Australian motorists,
combining for the first time the functionality of a smaller five-door with
traditional BMW values of driving dynamics, safety, comfort, quality and
innovation.
With this new model BMW was able to transfer its core DNA to a new vehicle
segment to create both a smaller car and a true BMW.
The new BMW 1 Series is a direct reaction to the needs of a young, active and
discerning generation.
Market analysts observed a remarkable growth potential within the premium
compact segment for a vehicle combining a high level of functionality and
enhanced comfort and safety with the distinctive character and driving
satisfaction of a BMW.
Until now, consumers seeking these values were made to compromise. However,
with the new BMW 1 Series, drivers who expect more than was previously available
have the opportunity to become acquainted with the typical qualities of the BMW
brand right down to the smallest detail.
When designing the BMW 1 Series, priority was given to the new model’s
uniqueness and the realisation of typical BMW qualities. The body, numerous
suspension and engine components, as well as a myriad of equipment details, were
developed specifically for this new model.
The new BMW 1 Series arrives with a choice of two free-revving petrol engines
with Double VANOS and VALVETRONIC technology and a sophisticated suspension
system to underline its sporting character.
3. Design
Unmistakably a BMW, the new 1 Series brings a dynamic new image to an
otherwise conservatively designed vehicle segment. With its blend of smooth
surfaces and sharp panel creases, the new 1 Series combines BMW’s new design
language with familiar styling cues in dimensions not seen in the BMW range
since the 02 Series of the 1960’s and 1970’s.
Kevin Rice, British-born design team project leader of the new BMW 1 Series,
said:
“The key to the BMW 1 Series design was to redefine the benchmark with
a unique premium product in its category. It communicates BMW’s ‘Driving
Pleasure’ philosophy with its proportions, surfaces and details, creating a
dynamic statement. The car embodies the typical characteristics of a BMW, but in
a smaller package that indicates its balance of practicality and sporting
ability. The driving experience stands out in its class and we wanted the car’s
looks to do the same.”
Exterior
Externally, the new BMW 1 Series features a
combination of familiar design traits and BMW’s new design language. From the
front, a new interpretation of the double kidney grilles, a feature seen on
every BMW since 1933, is located between the signature double headlamps.
Tapering into wide front wheel arches, the bold lamp clusters incorporate the
indicator lens and, when Xenon headlamps are specified, accent rings acting as
side lights, following the lead set by the 5, 6 and 7 Series.
A broad lower air intake is housed in the front valance, channelling air into
the engine intake while lower valance ‘spats’ ensure high-speed front-end
stability. An aerodynamic drag co-efficient of 0.31 also ensures the car slices
through the air quietly and economically.
The side view expresses the dynamic qualities of the car. The 2,660 mm long
wheelbase and short overhangs (737 mm front, 830 mm rear) mean the wheels are
pushed to corners of the body for optimum handling. The long bonnet with
pronounced power dome hides the longitudinally mounted engine and leads to a
steeply raked windscreen and low tapering roofline. Finally, the broad C-pillar
with the familiar Hofmeister kink (seen on all BMW’s since the 1500 and 3200CS
of 1962), and hatchback designed with integrated lip spoiler complete the
coupé-like side profile.
Drama is injected into the design with dramatic features such as the shoulder
and the sculpture lines above the sill, both reminiscent of the Z4 Roadster. The
sharp shoulder line starts at the headlamp, runs through the petrol filler flap,
onto the rear lamp cluster and around into the tailgate. The lower side
sculpture line starts at the front valance, runs round the front wheel arch
before creating a shallow curved crease in both doors. Rising over the rear
wheel arch, it finishes at the base of the rear valance.
From the rear, the purposeful stance of the new 1 Series continues with wide
rear wheel arches, clear lamp clusters and an aerodynamic rear valance lip
spoiler that adds a dramatic taper to the rear of the car while aiding stability
at higher speeds. Helping to reduce exterior clutter, the tailgate opening
handle is tidily integrated into the boot badge, providing an electronic latch
to open the boot. When opened for loading and unloading, the tailgate provides a
lofty 1.8 metres of standing height under the open boot lid.
Complementing the dramatic lines of the new car, the BMW 1 Series is
available as standard in three non-metallic colours – Jet Black, Japan Red and
Alpine White. Five optional metallic colours – Sparkling Graphite, Sydney Blue,
Quartz Blue, Sapphire Black and Titanium Silver are available. Four further
colours – non-metallic Nautic Blue and metallic Havanna, Sonora and Monaco Blue
follow shortly after launch.
Interior
The dynamic and sporting appearance of the 1 Series
surrounds an attractive and practical interior. With the seat base to the roof
lining measuring 963 mm in the front and 967 mm in the rear, headroom for
six-foot front and rear passengers is ample. Furthermore, class-leading shoulder
and elbowroom of 1,374 mm and 1,407 mm respectively in the front and 1,342 mm
and 1,414 mm in the rear, ensure that a great drive can be experienced with four
or five occupants.
Echoing the exterior, the new BMW 1 Series continues the theme of straight
and arched lines inside to give a clear, uncluttered appearance but with a
consistent focus on the essentials of driving. The packaging of the
longitudinally-mounted front engine, rear-wheel drive set up in the new BMW 1
Series means drivers used to other cars in the class will immediately notice the
accelerator, brake and clutch pedals are located centrally rather than being
offset to the right as in front-wheel drive competitors.
The dashboard controls feel equally natural, with everything falling easily
to hand. The centre console is inclined towards the driver, cocooning them and
immediately establishing a reassuring feeling of control.
Directly in front of the driver, the arched instrument binnacle houses core
driver information with classic twin dials showing road speed, engine speed and
the fuel gauge.
The space between the dials is devoted to displaying the mileage counter,
gear selection (automatic transmission only) and on-board computer messages that
can be scrolled through by pressing the button on the end of the indicator
stalk. To the right, the key is inserted and a starter button pressed to fire
the engine into life.
And while the newly designed key may not be familiar to BMW drivers, it still
benefits from advanced Key Memory, a feature on all BMWs. Using an exchange of
information between the key and the vehicle, the 1 Series recognises which key
is being used, and matches the vehicle settings to that key. Ideal for those who
share the use of the car, each key communicates the preferred settings for door
mirrors, air conditioning, radio stations and electric seating position.
Personalisation in the cockpit continues with all essential controls
positioned around the thick-rimmed three-spoke steering wheel that is adjustable
for height and reach. Additionally, multifunction controls for the steering
wheel, controlling the radio, telephone and two individually programmable
buttons allow the driver to keep their hands on the wheel at all times. The two
individually programmable buttons control features such as the radio mute and
air conditioning recirculation.
Recognising that, contrary to BMW 5, 6 and 7 Series models, a different group
of buyers will own a 1 Series, iDrive is offered as an option (standard when the
car is specified with Professional or Business Navigation system). Thus far only
available in BMW’s executive models, iDrive further optimises the interior
ergonomics by placing all secondary controls away from those essential for
driving - a feature unprecedented in a car of this size. Viewed on a 16:9
retractable screen at the top of the dashboard, a colour coded menu gives access
to communication, navigation, entertainment and climate control features as well
as individual vehicle settings, while a menu button located next to the
controller returns the user to the start point from anywhere in the system.
When specified in combination with Park Distance Control, the driver is also
made aware of any obstacles by a visual pictogram on the screen complemented by
an audible warning.
Seating and Materials
The quality of materials covering the
dashboard, interior panels and seat coverings are more familiar from the
executive segment. All seat upholstery combines two materials - the seat centre
material complementing the side bolsters and base outer panels. Standard on all
models is Moire cloth, available in two colour combinations – Anthracite with a
black interior and Alaska Grey with a grey interior.
The Motion cloth / Sensatec technical material combination are available as
an option on both models offering four different colour combinations – Alaska
Grey with a grey interior, Sydney Blue with a black interior, Sonora Grey with a
black interior and Graphite with a black interior.
Boston leather upholstery is available in four different colours – Alaska
Grey with grey interior, Beige with a brown / beige interior, black leather with
a black interior and Havanna Brown with a brown interior.
Complementing the seating and interior panel materials are trim strips on the
dashboard, door closing handles, centre console, door handles and the ring
around the starter button. Silver trims are standard on the BMW 118i while BMW
120i models feature a titanium-coloured matt finish. Black Gomera and Aluminium
Kodiak silver trim are optionally available for both models.
All upholstery combinations are possible with the sport seats (standard on
120i) which also feature a manual driver and passenger seat height and tilt
adjuster. Other adjustments for the sport seats include a front seat base length
adjustment and, uniquely in a car of this size, an electric adjustment for the
side bolsters. This is a feature previously only seen on the high performance M3
models in the BMW range – a clear indication that BMW expects 1 Series
purchasers to really test the car’s poised handling and road holding. Using a
button on the side of the seat base, the side bolsters move inwards to give
greater support to the driver and passenger, thus providing the ultimate lateral
support.
BMW’s commitment to the benefit of rear-wheel drive has a slight impact on
boot space, but with the rear seats in place, 330 litres of capacity is still
available. For the occasions when more room is needed, the rear seats split
60:40, folding virtually flat to reveal a capacious 1,150 litres of storage
space.
4. Chassis and suspension
The new BMW 1 Series offers an unsurpassed driving experience in the compact
segment. The first front engine, rear-wheel drive car in its class offers a near
perfect 50:50 weight distribution and neutral steering behaviour due to the
separation of drive and steering to different axles.
The unique rear-wheel drive arrangement also makes for the optimum
transmission of drive forces when accelerating. Unlike front-wheel drive cars
whose driven wheels can lose grip when pulling away, when the power is applied
on a BMW 1 Series, the weight transfers to the rear of the car – exactly where
the car has maximum traction. The more the driver demands dynamic ability, the
more advantageous this layout becomes. It sets a new agenda in the marketplace.
Another first for the segment is the car’s advanced suspension set up using
an all-aluminium front axle and five-link rear suspension. This arrangement
helps reduce the BMW 1 Series’ weight to 1,230kg (118i) / 1,260kg (120i) and
offers unrivalled levels of agility and ride quality.
Front axle: low weight, high level of comfort
With
technologies transferred from the BMW 5, 6 and 7 Series models, the BMW 1 Series
features an all-aluminium twin-joint tension-rod spring-strut front axle and
stabiliser bar. Offering an unmatched combination of excellent rigidity and very
low weight, the aluminium front axle, suspension struts and pivot bearings lower
the cars’ unsprung mass, thus contributing to its excellent agility, directional
stability and lateral grip.
The aluminium sub-frame is mounted onto the chassis using special rubber
mountings. Delivering the optimum combination of ride comfort and dynamic
performance, the rubber mounts minimise the vibrations, road and tyre noise that
would normally be transmitted through the car.
The subframe also mounts the 1 Series’ rack and pinion steering rack,
featuring a fixed steering ratio of 13.7:1. Connected to the three-spoke sport
steering wheel by a collapsible steering column, the rack provides a precise
steering feel with levels of feedback alien to front-wheel drive competitors.
Additionally, with the drive and steering transmitted through different axles,
drivers experience no torque steer – often the scourge of high-performance
front-wheel drive cars.
Five-link rear suspension
Unique in its class, the new BMW 1
Series features a five-link rear suspension. Instead of a double wishbone rear
axle, two single arms have substituted the usual upper and lower A-arms with the
new assembly producing less reaction to road imperfections. This innovative set
up provides the development engineers with an unprecedented basis for
fine-tuning of the chassis, suspension springs and dampers, ensuring that the
car adapts easily to most road surfaces. Formed from lightweight steel it is
fixed to the body by elastic mounts with the differential and rear axle rigidly
mounted, offering precise wheel guidance and reducing the typical conflict
between handling and ride comfort. Furthermore, the five-link rear axle delivers
additional lateral support, ensuring greater stability under braking and
acceleration loads.
For those wanting to tune the chassis dynamics further, the new BMW 1 Series
can be specified with Sport suspension. Lowering the suspension of the car by 15
millimetres, the revised spring and damper settings deliver a firmer ride,
increasing levels of road holding and cornering ability.
Brakes and wheels
The new BMW 1 Series offers the best
deceleration rates in its class. This is attributable both to the car’s light
weight and its high performance braking system using disc brakes all-round.
Vented front discs measure 292mm x 22mm on the BMW 120i (284mm x 22mm on 118i)
while the rear discs are 296mm x 10mm (280mm x 10mm on the 118i).
Brake pads feature an intelligent pad wear indicator. In conjunction with a
control unit, the brake pad wear sensors constantly monitor the condition of the
pad surface and combine this information with the current driving style to
predict when the brakes should next be changed.
Standard on the BMW 118i are 195/55 R16 Run-flat tyres fitted to 6.5J x 16
alloy wheels, while the BMW 120i comes standard with 205/50 R17 Run-flat tyres
fitted to 7J x 17 alloy wheels, but a wide choice of alloy wheel options, up to
7.5J x 17 with 225/45 R17 rear tyres are available.
5. Engines and transmissions
In order to reap the maximum reward offered by the class-leading chassis of
the new BMW 1 Series, BMW engineers demanded a range of exemplary engines. Both
engines offered in the 1 Series are four-cylinder power units.
These engines accentuate the character of the new model using intelligent and
unique engineering solutions to maximise performance and economy while
minimising emissions. No matter which model a customer chooses they will
purchase a car with best-in-class performance and very low fuel consumption.
Key facts
| BMW 118i |
95 kW |
Double VANOS and VALVETRONIC |
| BMW 120i |
110 kW |
Double VANOS and VALVETRONIC |
Each engine features four-valve technology derived from the four-cylinder BMW
3 Series power units, modified to the requirements of the BMW 1 Series driver.
The longitudinal mounting of each engine and rear-wheel drive is a critical
factor in achieving the car’s exemplary agility and directional stability. It
also allows the tight 10.7 metre turning circle.
On the button
Lifted from the BMW Z8, the starter button on
every 1 Series indicates that BMW recognises buyers of this car love driving.
The engine is started by pressing the dashboard button once (with the clutch
depressed). The control of the starting procedure then continues automatically
until the engine is turning over, with the same button also acting as the engine
STOP button.
The petrol engines – power on tap
The BMW 120i
The
most powerful petrol engine is the 1,995cc unit made exclusively at BMW’s Hams
Hall plant in Warwickshire.
Boasting variable valve timing incorporating VANOS variable camshaft control
on both intake and exhaust sides, as well as VALVETRONIC valve lift, it produces
an impressive 110kW at 6,200rpm. Maximum torque of 200Nm at 3,600rpm ensures a
strong response.
The 120i sprints from 0-100km/h in 8.7 seconds and goes on to reach a top
speed of 217km/h. The all-important stretch from 80-120km/h in fourth gear is
covered in a mere 8.4 seconds. Given such impressive performance the EU combined
fuel consumption of 7.4 litres/100kms is a bonus.
To put this in context, this is the level of performance achieved only by
leading sports and GT cars not many years ago.
Although based on the familiar two-litre, four-cylinder engine in the current
BMW 318i, the power output has been raised by 5kW. This has been achieved by
improving the intake and exhaust systems while a new electronic control unit
provides a more instant throttle response, a level of quality only previously
achieved on engines with individual throttles (M3, M5).
Each movement of the BMW 120i’s accelerator pedal also changes the intake and
exhaust noise to provide an unobtrusive sporting note appreciated by many
customers. Its smooth, free-revving characteristics never feel stressed even at
maximum revs, with balancer shafts in the 120i unit aiding its fluidity.
Ease of ownership is a key consideration and the oil level is electronically
displayed on the dashboard whether the car is stationary or on the move. There
is no longer any need for customers to open the bonnet for an oil check. In fact
it would be wasted effort, there isn’t even a dipstick.
VALVETRONIC: a proven formula for lower consumption
The BMW
120i is equipped with VALVETRONIC fully variable valve control. This system,
which negates the need for a throttle butterfly, ensures very significant fuel
consumption savings. The BMW patented system made its debut in the new
generation of BMW four cylinder engines in the 3 Series range which arrived in
Australia in December 2001. Since then this technology has been employed in the
new generation of eight and twelve cylinder engines and several hundred thousand
cars around the world have made a valuable contribution towards a reduction in
CO2 emissions.
Numerous international awards, including the European environmental magazine
award and the International Engine of the Year awards, are proof of the
innovation and effectiveness of BMW technology in reducing fuel consumption.
In contrast lean mix direct injection engines have not achieved great market
success. To date only some tens of thousands of engines have been offered in
limited model ranges and these can only use sulphur-free fuels.
VALVETRONIC-equipped engines do not require sulphur-free fuel or a special
catalytic converter and, for this reason, are already successfully incorporated
worldwide, playing a significant role in current and future engine technology.
The BMW 118i to be introduced to Australia in early 2005 employs the same
basic engine as the 120i, but is tuned to produce 95kW at 5,750rpm and 180Nm of
torque at 3,250rpm.
Manual and automatic transmission
The BMW 118i is equipped
with a five-speed manual gearbox as standard, while the 120i delivers a
six-speed manual gearbox as standard. The short throw, precise gear lever suits
the sporting character of the car and engine speed synchronisation after fast
changes feels seamless. Due to the flexibility of the engines the higher gears
offer sufficient power reserves to obviate ‘stirring’ the gears.
Both the 118i and 120i are available as an option with the six-speed
automatic transmissions that also feature in the new 5 Series. The range of
ratios match the engines’ abilities to exploit all driving situations and the
gearbox delivers seamless change quality. Sixth gear is an overdrive cruising
ratio in which top speed can also be reached.
As with all BMW automatic transmissions, the 1 Series offers the driver the
alternative to change gears manually using the Steptronic function. After moving
the lever to the left plane down-changes are delivered instantly by pushing it
forward, or the reverse for up-changes.
Servicing reduced to a minimum
No matter which engine the
customer opts for, with the BMW 1 Series they are getting a drivetrain with an
extremely modest service requirement. It is maintenance-free except for filter
replacement and an oil change. For instance, valve adjustment is no longer
necessary as this is carried out by hydraulic compensating shims. The camshafts
are driven by a chain that is designed to last as long as the engine. This
renders the expensive and time-consuming task of replacing the toothed belt
unnecessary, a job that still has to be frequently carried out on other
vehicles. Moreover, all transmissions have a lifetime oil filling.
Up to 25,000 kms (depending on how the car is driven) the driver is informed
by the service interval display when a change of oil and filters is due, thanks
to the Condition Based Servicing system. Prior to a long holiday, or at any
other time, the driver can obtain information on how long a part will last and
then decide whether or not to have it replaced before going away.
6. Safety
When the word safe is used in connection with a car the first thought for
most people is what happens to occupants in a crash? How well are they
protected? Even the FIA’s NCAP test bases its safety star ratings on the effects
on occupants and pedestrians during a crash.
Safety in this context is paramount. Arguably, though, the dynamic behaviour
of a car and the electronic systems put in place to help a driver avoid an
accident in the first place is even more important. These so-called active
safety features are given the highest degree of focus and attention by BMW for
it is only after exhausting every possible avenue to help prevent accidents from
happening that passive safety features become important.
But, however good a car is there are many variables that can result in an
accident. In these cases the passive safety features must minimise the potential
consequences.
1 Series : a focus on both halves
The new BMW 1 Series might
be the smallest BMW but it sacrifices nothing to achieve the highest standards
for both active and passive safety. It is expected that the car will reflect
this with a five star Euro NCAP rating (expected January 2005). In fact, 1
Series has the enormous benefit of being able to draw on BMW’s huge palette of
safety innovations developed within its range.
The body: more room for enhanced safety.
The new BMW 1
Series conveys a feeling of safety unparalleled for a vehicle of this class.
It begins with body and build quality, which fully lives up to the high
standard of all BMW vehicles. Every single body component excels due to
stability, fitting accuracy and high-quality finishing.
The use of high-strength steels in conjunction with extensive support
structures and selectively designed reinforcements make the body extremely
rigid. This high level of torsional stiffness contributes greatly to the
vehicle’s agile handling, precise steering and outstanding driver enjoyment.
In addition, the new BMW 1 Series’ extremely robust body structure offers
invaluable safety reserves in the event of a collision. In numerous computer
simulations and crash tests using real vehicles, the effects of many crash
situations have been analysed with attention to the smallest detail.
As a result, the new BMW 1 Series’ extremely stiff passenger cell combined
with perfectly harmonised support structures and deformation zones offers an
unparalleled level of protection for its occupants for a vehicle in its class.
Preventing an accident : 1 Series Active Safety
Active
safety starts with the configuration of the car. A stiff, torsionally rigid body
with near-perfect 50/50 front/rear weight distribution and lower unsprung weight
due to aluminium alloy suspension components all combine to provide both
straight line and cornering stability, poised and predictable handling and a
ride quality that absorbs road imperfections without being thrown off course.
The 1 Series starts with a solid foundation and being rear-wheel drive,
suffers no degeneration of its steering by having to put power through the
steered wheels.
More driving fun, more control, more safety: the BMW driving stability
systems.
A chassis and suspension system with high dynamic reserves;
precise steering and a self-monitoring brake system that can be applied in
measured and accurate doses through the latest ABS technology, constitute the
basis for the BMW 1 Series’ unique combination of driving pleasure and safety.
These life-saving features are complemented by standard DSC Dynamic Stability
Control, which contributes both to dynamic handling and safety.
This system makes ventures beyond the car’s already high suspension limits
much less risky, preventing the vehicle from swerving out of control by applying
the brakes to individual wheels and, if necessary, reducing engine power.
When performing abrupt evasive manoeuvres or driving on slippery surfaces,
DSC helps to master critical situations and to make the necessary course
correction.
These systems include ABS anti-lock braking, ASC (Automatic Stability
Control), DSC (Dynamic Stability Control), DTC (Dynamic Traction Control), DBC
(Dynamic Brake Control) and CBC (Cornering Brake Control).
Intelligent brakes
ABS is now familiar to almost all drivers
but in the 1 Series it is mated to particularly powerful brake discs that
deliver best-in-class deceleration. The system also features a brake pad wear
indicator that keeps the driver informed of the level of wear, preventing the
need for unnecessary checks at the dealer. The sensors which measure brake wear
also calculate automatically when the brake pads will need changing and
intelligently consider not only existing wear levels but also predict brake pad
wear according to driving behaviour. This is another first in this class of car.
A further emergency braking aid that also complements DSC is Dynamic Brake
Control (DBC). When the brakes are applied suddenly, DBC increases the brake
pressure if it detects that the pressure applied by the driver is insufficient.
DBC is activated until the maximum rate of deceleration is reached, irrespective
of how hard the pedal is pressed.
Also standard is Electronic Brake Force Distribution, constantly monitoring
the wheel speed of the rear axle compared to the front. Under hard deceleration
when the rear of the car can become unstable and the rear wheels threaten to
lock, the electronic distributor limits pressure to the rear to re-establish
directional stability.
DSC, DTC and CBC
DSC is standard on all BMW 1 Series models.
It detects unstable driving conditions such as under or over-steer within
microseconds and takes action to stabilise the car. Using information supplied
by the ABS sensors, steering angle, lateral acceleration and yaw sensor, the DSC
system will reduce engine power to try and overcome the situation. In extremes,
it will then apply individual brakes to bring the car back under control.
Pressing the DSC button on the centre console once activates DTC. DTC uses
the same information as DSC but with an increased threshold, allowing five per
cent more wheel slip before intervening. As a result, traction on slippery
surfaces is improved, as a little slippage is beneficial in order to gain
momentum. Controlled high speed driving is also favoured thanks to fewer system
interruptions. Press the button and holding it in for a few seconds a second
time disables the system entirely.
DSC can also be deactivated by the driver, as BMW considers an electronic
suspension control system an aid to the driver and not to the suspension. In
other words, BMW believes that the function of the suspension should not be
dependent on the use of an electronic system.
ASC, which is integrated into DSC, has the same function as a mechanical
differential lock. It helps the driver to set off smoothly in deep snow, on
off-road tracks or on slippery uphill gradients.
Finally, CBC is activated long before the ABS system cuts in to stabilise the
car in high-speed corners. By slightly reducing the brake pressure on the inner
front and inner rear wheels, any risk of the car spinning while braking in a
high-speed corner is significantly reduced.
Tyre safety package
Run-flat tyres and Tyre Puncture Warning
System are standard on all 1 Series models. Using BMW’s Tyre Puncture Warning
System that constantly monitors the rolling circumference of all four wheels,
the driver is notified of a drop in tyre pressure by the dashboard indicator.
Yellow signifies a drop in pressure of up to 30 per cent but when it changes to
red, the driver is alerted to a fully flat tyre.
BMW accident research shows that almost 80 per cent of all blowouts are
detectable in advance because they are preceded by a gradual loss of pressure,
this research highlighting the importance of the Tyre Puncture Warning System.
With Run-flat tyres, the punctured tyre no longer needs to be immediately
swapped for the spare, consigning roadside tyre changes to history. Even with
all four tyres flat, the car can travel at speeds of up to 80km per hour for up
to150kms in total safety, with the driver still supported by the vehicle’s
safety systems such as DSC and ABS. With roadside assistance services, including
the AA and RAC, reporting over one million call outs for punctures every year,
the benefits of runflat technology again come to the fore.
The BMW system detects all these risk situations at an early stage. Tyre
pressure level is constantly monitored by an intelligent system evaluating the
wheel speeds on all four wheels, with the necessary data provided by the ABS
sensors. If the actual values deviate too much from the set values, a warning
signal is triggered.
Light repairs on the move
Another ground braking technology
to feature on the new 1 Series is BMW’s Light Control Module (LCM). Using the
familiar Check Control system, the car recognises the failure of any rear lamp
bulbs including brake lights, indicators and fog lamps, and alerts the driver.
The car then counteracts the problem, in the case of the brake lights, by
supplying power to the tail lamp when the brake pedal is depressed. Thus, the
car can be driven safely and legally until a replacement is obtained and drivers
travelling behind are still fully alerted to the car braking ahead.
The best braking system: Brake Force Display
The new BMW 1
Series is the first compact vehicle to be sold in Australia with two-stage brake
lights. This feature is already fitted to many existing Australian specification
BMW models.
The intensity of the 1 Series’ brake lights varies depending on the severity
of the braking manoeuvre. Traffic behind has a clear visual signal as to whether
the 1 Series is undergoing a routine braking or if the car is heading into a
potentially dangerous situation.
If the brakes are applied normally, the brake lights provide the usual level
of light. However, if the brakes are slammed on, or the ABS system is activated,
a larger area is illuminated. The brighter light, in turn, prompts following
drivers to also brake as hard as possible.
BFD uses the ABS wheel sensors to detect deceleration rates and, when it
reaches five metres per second squared or when the ABS cuts in, BFD illuminates
an additional panel of brake lights to issue a clear warning. Thus, the chances
of a rear end collision are reduced.
The warning is doubly appropriate, as the new BMW 1 Series, with its large
diameter brake discs all round, has the best stopping power in its class. The
remaining service life of other wear parts is also constantly checked and shown
on the onboard computer display, situated between the speedometer and rev
counter or via the optional dashtop-mounted 6.5-inch colour monitor.
Xenon headlamps
The bright white light of Xenon gas
discharge headlamps delivers daylight quality to both high and low beams. The
improved road illumination provides a marked increase in safety, and reduced
strain, during night time journeys. Xenon headlamps are optional on all BMW 1
Series models.
Accidents can happen........... passive safety
Despite the
plethora of active safety elements described above, accidents can and do happen.
A key safety feature of the BMW 1 Series is its high strength body. Occupants
sit in a survival cell that is strengthened with reinforcements in the A and
C-pillars to protect passengers in the event of the car rolling over, and by
ultra-durable steel supports with special reinforcements to strengthen the
floor.
All of this strengthening has been put to the test in numerous computer
simulations and crash tests, with the effects and results of all conceivable
crash situations analysed and the information used to provide maximum protection
to occupants. For example, in the event of a head-on collision, the driver’s
legs and feet are protected from injury by pedals that move out of the way.
Front seat passengers are similarly protected by an energy-absorbing footrest
that substantially reduces impact forces transmitted into the footwells. Forces
from a head-on collision are absorbed by deformation zones through precisely
calculated, predetermined channels. This ensures that energy is diverted from
the front supporting structure and absorbed before it reaches the passenger
cell.
In the event of a side impact, occupant safety is enhanced by high-strength
door reinforcing bars and safety latches alongside a reinforced B-pillar, and a
strengthened instrument panel between the A-pillars. Passengers are protected
from rear impacts by a deformable area in which longitudinal braces, side panels
and the boot floor combine to divert and absorb any impact energy before it
reaches the passenger cell.
Intelligent safety
Co-ordinating the airbags and other
safety systems on the 1 Series is Advanced Safety Electronics (ASE). Using a
‘byteflight’ network of fibre-optic cables to link the decentralised impact
sensors and airbags, ASE recognises the location and severity of the impact and
triggers the appropriate response. This includes selecting which airbag to
inflate and at what intensity or whether firing the seatbelt tensioners will be
sufficient, thus reducing repair costs. Concurrently, the fuel pump and
alternator are disconnected and battery safety terminal deactivated, minimising
the risk of fire.
Additionally the system opens the central locking and turns on the interior
courtesy lights and hazard warning lights to attract attention. The operation of
these remaining electrical functions is made possible by an on-board auxiliary
power supply.
Six airbags
Protecting all occupants, the new BMW 1 Series
features six airbags as standard. Intelligent two-stage airbags protect the
driver and passengers depending upon the force of the collision. Using the
principle that lower inflation can be better in some circumstances, the danger
posed to the front seat occupants from the impact is immediately calculated and
the airbags inflated at the appropriate speed and to the appropriate size. Front
side airbags are integrated into the side of the seats while BMW’s Advanced Head
Protection system fires curtain head airbags extending from the base of the
A-pillar to the top of the C-pillar, protecting both front and rear passengers.
Integrated into the roof frame, the head airbags inflate immediately thanks to
their honeycomb structure and stay inflated for longer than other airbags. Thus,
the head airbags continue to protect the occupants in the event of the car
rolling over or from any objects entering the car from outside.
Smart seatbelts too
In addition to the airbag detonation,
passengers are protected from injury by inertia reel seatbelts and
pyrotechnically activated front and rear seatbelt tensioners. Additionally,
adaptive belt force limiters monitor the strength of any impact and apply the
right degree of restraint, pulling the occupants back into their seats. The belt
force limiters ensure that the airbags and safety belts protect passengers more
gently as less force is exerted on their heads and chests, preventing injuries
caused by the tightness of the seatbelt.
The belt fasteners are mounted on the seat frame, which ensures that the belt
position in the region of the hip remains constant even when the seat height is
adjusted.
The belt latch tensioners and the optimised belt guide ensure that the
restraint systems also function perfectly in the event of an accident. They hold
the body in the correct position in order to prevent injury.
A safe place for children
Younger members of the family can
also travel in safety thanks to ISOFIX child seat fixings in the rear seats.
Standard on the new BMW 1 Series, the pair of twin fixing points locates an
ISOFIX-equipped child seat directly to the body of the car ensuring it remains
rigidly fixed in position.
Intelligent Battery Sensor
While obviously less serious than
an accident needing an airbag deployment, a car with a flat battery is always
inconvenient. To reduce the chance of late night non-start situations, all BMW 1
Series models feature an Intelligent Battery Sensor (IBS). The battery is
constantly monitored and should a low battery charge be noted, the system reacts
in two ways. Firstly, the engine idle speed increases to provide additional
charging capacity. If that does not suffice, less energy is temporarily diverted
from non-essential systems to ensure that enough power is available for the next
time the car is started.
PDC – Park Distance Control
To prevent slower speed
accidents, owners can specify two levels of audible Park Distance Control (PDC)
– front and rear or rear only. If Professional or Business navigation is also
specified, a visual pictogram appears in the retractable monitor, further
simplifying parking and slow speed manoeuvrability. Should the worst happen, the
front and rear bumpers housing the PDC sensors regenerate to their original
shape at impacts of up to 4km/h and in collisions up to 15 km/h, deformable
elements behind the bumpers crumple to prevent damage to the vehicle structure.
These elements are easily and inexpensively replaced.
7. History
The traditional architecture of BMW’s nomenclature has been established for
over 30 years. The 3, 5 and 7 Series have formed the backbone of the range for
this period with 6 and 8 Series making an appearance too. But there has never
been a 1 Series. Would it be safe to assume that there is no history or heritage
to consider?
The answer is no. Although it is true that there is no lineal predecessor to
this exciting new model, BMW has a long history of producing smaller cars. In
fact the company’s very first automobile – the 1928 BMW 3/15 – was a small four
cylinder, four seater. It was based on the ubiquitous Austin Seven built under
licence by the Dixi company that was taken over by BMW in 1927.
The 3/15 (denoting its 15bhp engine) was more a ‘car for the masses’ in the
period of the Great Depression, than a premium car for the elite. As BMW moved
into the 1930s it changed the Seven-based car beyond recognition by producing
the 3/20 and 303 before moving firmly into the premium segments with the 327 and
328 and, by the end of the decade, the 335.
In the 1950s BMW was again tempted into the mass market in an economic
climate that was typified by post-war austerity and the Suez crisis. Between
1955 and 1962 the company built over 160,000 three- (and four-) wheeled Isettas
– a small egg-shaped car that became the darling of the city for many a year.
This car, powered by a single cylinder BMW motorcycle engine, spawned a larger
twin cylinder BMW 600 from 1957-1959 and, from 1959 the BMW 700.
The BMW 700 continued to use a BMW twin but in a full four seat,
Michelotti-inspired body that looked more like a traditional car. The 700 was
popular (over 188,000 were made) and was produced in saloon, coupé and cabriolet
styles. Like its distant ancestor, the 3/15, it was successful in motor sport
too. The 3/15 had won the gruelling Alpine trial of 1929: the 700 achieved many
touring car class successes in races, rallies and hill climbs between 1959 and
1962. One picture of a touring car race at the Nürburgring shows no less than 20
BMW 700s and only two other makes, such was its dominance in the 700cc class.
Coming closer to the present, three BMW cars bore the number one. The M1 of
1978, the 1988 Z1 and the E1 of 1991. None are relevant to the segment that the
new 1 Series will contest but all, at least, share the number. The M1 was BMW’s
supercar developed for racing and the road while the others were developed by
BMW Technik GmbH, BMW’s think tank for materials and drive systems of the
future. The Z1 roadster achieved immortality for its pin sharp handling,
recyclable plastic bodywork and drop down doors while the E1 was a conceptual
city car that was powered by electric batteries and seated four in comfort.
So, some tenuous but interesting historical links but none that really have
any strong relationship with the new BMW 1 Series. However, there is one model
from the past that did fulfil a similar role within the BMW range ..... and its
name began with a ‘2’: the iconic BMW 02 Series topped by 2002.
Produced between 1966 and 1976, almost 850,000 found homes with happy
customers. Produced in a bewildering number of engine and body styles, the 02
series was composed of a 1600-2, 1600TI, 1602, 1600 Touring, 1802, 1800 Touring,
2002, 2002 Cabriolet, 2002ti, 2000 and 2002tii Touring, 2002tii, 1502 and the
flamboyant 2002 turbo, Europe’s first turbocharged production car.
This was the predecessor of the first (E21) 3 Series and established a
reputation for being the ‘ultimate driving machine’. It was praised by the
press, and loved by drivers, for its poised sporting handling, best-in-class
performance and impeccable build quality. It is true to say that the 02 series,
more than any other model range, formed the bedrock for BMW’s reputation and the
blueprint for all BMW models that were to follow.
So, the -02 series is a real ancestor for the new 1 Series, not only in
spirit and genetics but also in size. The 2002 is only three millimetres longer
than the 1 Series and as subsequent evolutions of the 3 Series have grown in
size to accommodate consumer wishes, the 3 has left a gap for the 1 Series. A
comparison of the principal dimensions makes interesting reading.

Interestingly, although body length and height are very similar, the width,
wheelbase and track are vastly different. This serves to support BMW’s
philosophy of creating 50/50 weight distribution, a ‘wheel at each corner’ and
wide track for the utmost driving stability. The new BMW 1 Series is set to
carry on and enhance a very rich reputation for agile spirited BMW cars that
reward their drivers .... and their passengers.
8. Production
The new BMW 1 Series production at the Regensburg plant –
commitment to Germany as an industrial location.
The decision to produce the new BMW 1 Series at the BMW facility in
Regensburg, East Bavaria reaffirms BMW’s commitment to Germany as the principal
production base for its passenger cars.
The plant has been expanded, modernised and adapted to cater for increased
production of both BMW 1 and 3 Series models.
Innovations on the production line: Powder instead of varnish.
It has been a long time since BMW began using water instead of
hydrocarbon as a solvent in vehicle painting, however the method of applying the
topcoat to the new BMW 1 Series is unprecedented in vehicle production.
The final clear coat on every BMW 1 Series is applied as a powder clear paint
– a feature unparalleled in terms of environmental compatibility, brilliance and
depth of colour. Neither water nor solvents are used for applying the paint so
that no waste liquid is generated in the process.
Chemical agents for cleaning the painting facilities are also a thing of the
past. The powder’s degree of utilisation is more than 97 percent, thus reducing
the waste produced in the process to a minimum.
Accuracy at its best: the engine is automatically bolted on to the
transmission.
For the first time in the world, the transmission of
the new BMW 1 Series is attached to the engine block by robots.
A facility to carry out this job was developed in just six months and
integrated into the current production process. This automated assembly step
leads to an increase in quality, as connecting the engine to the transmission is
an extremely challenging job.
A core element in the automatic mounting process is the use of images. In
all, there are six cameras, three of which are located on the robot’s arm. These
cameras pinpoint the position of the individual components. Robots bolt the
engine on to the transmission with maximum accuracy, working to an extremely
fine tolerance of only 0.15 mm.
The cockpit: assembled by hand, installed by robots.
Another
innovation in the production of the new BMW 1 Series is the installation of a
pre-assembled cockpit module by robots – something that has never before been
put into practice.
As a preliminary step, specific components, such as the instrument panel,
control elements, or the air-conditioning system, are pre-assembled by hand to
form the cockpit.
This process is followed by testing and taking measurements of the entire
module. After that, a robot installs the cockpit into the vehicle and screws it
down in one single step. This high degree of automation boosts efficiency,
reduces the material needed at the assembly line and reduces the number of
necessary steps. This increases flexibility in dealing with fluctuating demand
or larger production volumes.
Perfect ergonomics as a prerequisite for premium quality.
To
provide the best possible working conditions for the staff, ergonomics at the
assembly lines for the 1 and 3 Series production has been optimised. The
assembly areas are kitted out with a height-adjustable moving floor adaptable to
each individual employee.
The workers move at the same speed as the vehicle, fulfil each individual
step in an upright position and can lower, raise, and turn the vehicle as
required.
The history of the Regensburg plant.
Regensburg is one of
three BMW sites in Germany devoted to the production of automobiles and it is
the second biggest plant within the worldwide BMW production network.
Vehicle production commenced back in November 1986 and more than 237,000
automobiles were built there in 2003.
9. Low Ownership cost
Much less time for maintenance – more time for driving
pleasure.
One of the top priorities in the development of the new BMW
1 Series was to minimise the time and cost of maintenance and servicing in order
to ensure constant availability of the BMW 1 Series without any major
interruptions.
There is no other vehicle in its class that requires less service and
maintenance than the new BMW 1 Series.
Through the technology used for the engine and drivetrain, BMW has set new
standards utilising sophisticated technologies that make many parts and
components of the new BMW 1 Series maintenance-free.
BMW uses maintenance-free camshaft chain-drive for all engines, a substantial
saving over toothed belts, which require replacement on rival vehicles every
60,000 km to 120,000 km.
There is also no need for valve adjustment, as the new BMW 1 Series features
hydraulic valve-play compensation. Poly-V-belts are used for driving the
alternator, the hydraulic pump and water pump, which consequently do not have to
be replaced.
The gearboxes on all BMW 1 Series are all filled for life and thus require
very little maintenance. A further maintenance free fitting is the stainless
steel exhaust.
Service intervals depend on how hard the car is driven.
In
1982, BMW abolished fixed service intervals for parts and components subject to
wear and tear. Instead, each individual BMW constantly calculates the remaining
interval and tells the driver when the car is next due for servicing. This value
depends on the customer’s driving style and the actual wear.
The new BMW 1 Series also benefits from the Condition Based Service (CBS)
concept, which was used for the first time in 2002 in the 7 Series. Sensors and
sophisticated software algorithms constantly monitor selected parts and
components subject to wear and tear.
This enables the customer to use the onboard computer or iDrive to retrieve
individual information on when the engine oil, micro filter, front and rear
brake pads, coolant, brake fluid and spark plugs have to be replaced.
An enhanced use of service limits combined with a reduction in maintenance
times has ushered in a new era in vehicle service and maintenance.
Better planning of service appointments.
This concept makes
vehicle servicing much more transparent for consumers. If, for example, the
owner of a new BMW 1 Series plans to go on a longer trip, he or she can
determine independently whether to have the car serviced before or after the
journey. This avoids situations where, for example, the brake pads suddenly have
to be replaced in the middle of a holiday.
Thanks to CBS, the workshop is also in a position to acquire an overall
picture of the maintenance and servicing as soon as the vehicle is accepted for
servicing.
A vehicle key that knows when the brake pads have to be replaced
next.
The innovative key system, which was first featured in the BMW
7 Series, is an effective tool for the workshop when accepting the car for
maintenance and service.
The key not only functions as a locking device, but also stores all
service-relevant vehicle data. Service staff used to gather the information
needed via a tiresome and time-consuming question and answer game. These days,
however, they get the information needed in a flash. Using a key-reader, the
information stored in the key, such as mileage, vehicle identification number,
initial registration date, colour, upholstery and equipment codes and the
interval until the most important wear parts are due for servicing, is retrieved
and instantly displayed on a computer screen.
Minor accident – minor costs.
The costs caused by minor
traffic accidents are a nuisance. The new BMW 1 Series features bumpers that
recover from small impacts at speeds of up to 4 km/h. If the collision is more
serious, deformation elements behind the bumpers, which are easy to replace,
help to keep the repair costs to a minimum.
In collisions up to a maximum speed of 15 km/h, these elements insulate the
vehicle’s structure from damage. In development, much attention was paid to
avoiding expensive repair work on damaged body parts.
10. Recycling
If, after many years of usage, its lifecycle comes to an end, the BMW 1
Series becomes the perfect choice for recycling.
Right from the outset, recycling specialists worked with BMW designers in the
development of the model with a view to later recyclability. As a result, the
new BMW 1 Series already complies with EU legislation that does not come into
effect until 2015.
A recycling-oriented method of joining and material selection plays a key
role in this process. One example is the bumper panel. Although made from one
material – unusual in itself today - they meet all functional safety
requirements.
Recyclability down to the smallest detail.
When devising the
safety and drive-relevant components for the new BMW 1 Series, special attention
was paid to the careful use of resources and the environmentally compatible
recyclability of components and materials.
Employing the “Direct Firing” method, which was developed by BMW, the airbags
can be “neutralised” quickly and cost-efficiently. All that has to be done is to
unplug the airbag control unit and to connect the airbag system to the igniter
by means of an adapter.
Europe-wide network to ensure environmentally friendly
recycling.
In order to drain and dry all fluid-related components
(oil, brake fluid, water, fuel), all drainage points can be easily accessed
using standard tools. For special cases, BMW has developed drainage tools and
made them available to recycling firms.
Moreover, BMW is strongly committed to ensure that their products are
competently recycled. In 2001, BMW introduced a recycling network across the
whole of Europe to cater for the environmentally compatible recycling of all BMW
vehicles.
