Concept

A new model made by BMW – a revolution in the compact class.
High expectations, growing demands and new challenges characterise the launch of the BMW 1 Series. With this new model BMW was able to transfer typical brand qualities to a new vehicle segment – driving dynamics and premium quality. The BMW 1 Series was designed with those drivers in mind who on the one hand opt for an agile, functional car, but on the other do not wish to do without sporty motoring characteristics and perfection right down to the smallest detail. For these drivers the BMW 1 Series is the fulfilment of a long-cherished dream. After all, it is a typical BMW, and it also provides all qualities expected of its segment. By extending its model range BMW has reacted to the needs of a young, active and discerning generation of consumers. Entering this segment is both a challenge and at the same time the chance to convince a new class of clientele of the typical qualities of BMW brand cars.
The most attractive offer on a growing market.
Market analysts are observing a remarkable growth potential within the premium compact vehicle segment. Customer interest tends to focus on hatchbacks with a variable interior. Modern compact vehicles combine a high level of functionality with enhanced comfort and safety, thereby meeting demands that only higher class vehicles were able to fulfil in the past. Up until now the decision to purchase a compact class vehicle always involved making a compromise. It was the BMW qualities, namely superb driving dynamics and a distinctive character offering high quality, which many customers searched for in vain. BMW is now giving them the opportunity to become acquainted with the typical qualities of the brand: it is an opportunity for those drivers who expect more than was previously available.
A unique response to specific demands.
BMW models stand out against their rivals in all classes due to innovative design, advanced technology, outstanding road performance and motoring characteristics. BMW owners have, therefore, made a wise decision in favour of driving pleasure. They appreciate both the outstanding standard of quality offered by a premium car and the sporting character of their BMW. Furthermore, 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.

And we applied the same principles of development and production that helped to take the BMW brand to leading positions in other vehicle segments. This was the only way to create a BMW that also fitted into the compact class. Nevertheless, an extraordinary level of flexibility during the production process facilitates a maximum degree of effectiveness and rationalisation. The development of the BMW 1 Series has brought about a considerable increase of product capacities, which in turn has resulted in a higher workload and the creation of new jobs.

Suspension

The typical BMW suspension and drive concept – the perfect formula for dynamics, comfort and safety.
Compact class handling, BMW dynamics – the new formula for driving pleasure in this segment. The BMW 1 Series is the only model in its class to transmit engine power to the road via the rear wheels. This principle – front-mounted engine, rear-wheel drive – enables a particularly well-balanced distribution of weight and optimum traction. Moreover, there is absolutely no torque steer. It is not without reason that rear-wheel drive is so successful in higher vehicle segments, in motor sports and now also in the compact class, where the BMW 1 Series is making its mark as a car with the highest possible standards in dynamics, comfort and, last but not least, safety.
Ideal dimensions for more driving fun: well utilised thanks to rear-wheel drive.
With their light weight and fairly short exterior dimensions, compact class vehicles are absolutely predestined to provide driving pleasure and dynamic handling. However, thanks to an extremely short body overhang at the front end and a particularly long wheelbase (2.66 metres or 8.7 ft) and wide track, the BMW 1 Series also has the necessary prerequisites for agile but stable road holding. The BMW 1 Series is able to make the most of these advantages, as it also has an additional, decisive trump card. It is the only vehicle in its class to combine the benefits of compact dimensions with the positive qualities of transmitting power to the rear wheels. Optimum traction and well-balanced weight distribution are the typical qualities of rear-wheel drive now also available in the compact class. In spite of this sophisticated concept, the BMW 1 Series is by no means one of the heaviest in its class. On the contrary – thanks to the specific use of lightweight materials such as high-strength steel and, wherever feasible, aluminium – its unladen weight is lower than average for its class. The BMW 116i, for example, weighs just 1,205 kg (according to DIN, excluding driver).

With all these characteristics, the BMW 1 Series offers a new dimension in driving pleasure. Its drive concept secures its pole position in the field of driving dynamics.

Optimum driving position for enhanced driving pleasure.
When sitting behind the wheel, it becomes evident that the BMW 1 Series was designed right from the start to meet the needs of the active driver. The steering wheel can be adjusted both horizontally and longitudinally to many different positions. The driver can rest his left foot on an ideally positioned footrest. Furthermore, accelerator, brake pedal and clutch are located in the centre in relation to the driver’s seating position – by no means a regular feature in the compact class. For constructional reasons, vehicles with front-wheel drive usually have pedals situated slightly to the right of the ideal position, whereas the ergonomic seating position in the BMW 1 Series already makes a substantial contribution to the enhancement of driving pleasure.
A new experience in the compact class: dynamics coming from the rear axle.
Never before has travelling in a vehicle of the compact class been so closely associated with driving pleasure as in the BMW 1 Series. And there is a simple explanation for this: engine output can be transformed into forward thrust in many different ways. Dynamics, however, can only be achieved if engine power is transferred to the rear axle. Superiority of rear-wheel drive is largely due to laws of physics, its effect being perceptible every time the accelerator is stepped on. The moments of inertia occurring during acceleration put a strain above all on the rear axle. Vehicles with front-wheel drive have more difficulty with power transmission when accelerating from a standstill, as the front end is relieved of weight, thus reducing the front wheels’ road contact. In the case of vehicles with rear-wheel drive, however, the burden on the rear wheels caused by the dynamic load transfer has a positive effect.
Optimum traction thanks to a well-balanced distribution of weight.
The benefits of the BMW Series’ drive concept can be felt during every mile – irrespective of whether the car is being driven like a sports car along country roads, in city traffic or on the motorway. The drivetrain extending back to the rear axle and the front-mounted engine and gearbox prevent the vehicle from being “nose-heavy�. Instead, a balanced distribution of weight is achieved with 50 percent of the total weight placed on both front and rear axles. The lateral forces have an even effect on all four wheels when driving in bends at high speeds. Consequently, the BMW offers convincing road holding that makes a significant contribution to its sporting character. A tendency to understeer, as is usually the case with front-wheel drive concepts, does not exist in a BMW 1 Series, even when driving in tight bends and at high speeds. The car sticks to the road even on bad surfaces. The positive effects of the rear-wheel drive are increased when the car is fully loaded, whereas on vehicles with front-wheel drive, heavy loads tend to reduce weight on the front axle, which results in a negative effect on traction. This does not happen in the case of a BMW 1 Series car.
Greater precision even when taken to the limit.
Even when driven in a sporty fashion, the BMW 1 Series stays precisely on course when driven at speeds where conventional compact class vehicles have already reached their limits of stability. Furthermore, the neutral suspension design ensures a masterly handling of critical situations. In precarious situations – for example, when suddenly having to avoid an obstacle – DSC Dynamic Stability Control provides assistance in keeping the car on course. The BMW 1 Series features driving dynamics control as standard, which helps the vehicle to maintain road contact even when making abrupt steering manoeuvres and unusually sudden changes in direction. By slowing down each individual wheel and reducing the engine output, the vehicle is prevented from swerving out of control. DSC is activated gently and only if physical limits are in danger of being exceeded. This has absolutely no influence on the sporting character of the BMW 1 Series car.
Five-link rear suspension: elaborate new development for greater agility.
The entirely newly developed five-link rear suspension is based mainly on a double wishbone rear axle with a rear-sited track rod, the upper and lower A-arms of which have each been substituted by two single arms. This has the advantage – irrespective of the space available – of being able to freely determine the effective virtual kinematic point. The result is a kinematic elasticity which, over a wide range of suspension travel, facilitates precisely the wheel guidance required for the desired road performance. Thanks to small, effective lever arms there is little reaction to disturbances. Both the large base minimising track and camber effects on the wheel carrier side and the extremely stiff control arms, as well as the rigid rear axle base and the connection to the body by means of thrust rods, facilitate an extremely precise wheel guidance, a prerequisite for the vehicle’s agile road performance. The large rear axle support is of great significance for both motoring performance and acoustic insulation. For example, this construction takes into account the deployment of high-performance, high-torque engines and tyres featuring emergency running properties.
The front axle: low weight, high level of comfort.
The design of the front axle is also unrivalled in the compact class. The double-joint tension-rod spring-strut suspension featuring a stabiliser bar is made chiefly of aluminium. Thanks to this, we have achieved a perfect symbiosis of maximum stiffness and low weight. As the struts and the pivot bearings are also made of aluminium, it was possible to considerably reduce unsprung weight.

On the whole, the principle of lightweight construction has a positive effect on weight distribution. In addition to the extreme stability of arms and struts and the accurate wheel guidance, this is a further contribution to the enhancement of BMW 1 Series’ driving dynamics. The hydraulically damped engine mounts ensure a remarkably low level of noise and vibration.

Following the example of motor sport.
Motor sport is the most impressive example of the fundamental superiority of rear-wheel drive. Cars with rear-wheel drive traditionally dominate almost every kind of automotive sport. In contrast to rallying, which is chiefly dominated by four-wheel drive vehicles, power transmission to the rear wheels remains first choice, especially for track racing on tarmac. The higher the demands on traction and engine performance, the more obvious the advantage of this drive concept becomes – and that includes Formula 1 racing. However, the advantages of rear-wheel drive also become evident in the rivalry between near-production vehicles. In some cases, manufacturers of vehicles with front-wheel drive are even beginning to re-equip their series production models with rear-wheel drive.
No torque steer, optimum steering precision.
Over the decades, modern suspension technology has considerably reduced the design-related disadvantages of front-wheel drive in everyday traffic situations. Nonetheless, the negative effects of torque steer are still noticeable. Particularly on wet or slippery road surfaces, front-wheel drive can impair steering precision. Sophisticated control systems can only compensate to a certain extent for such restrictions in driving comfort. For this reason the BMW 1 Series is synonymous with a consistent optimisation of driving dynamics, comfort and active safety. The clear distinction between the drive and steering functions results in an uncompromising driving experience and emphasises the BMW 1 Series’ dynamic character.

Drive

The driving force behind driving dynamics.
In terms of driving dynamics the BMW 1 Series is taking the lead in its segment. This is being achieved not only because of the rear-wheel drive principle which is exemplary for the compact class, but also due to the engines used. Each power unit available for the BMW 1 Series ideally accentuates its character with intelligent, unique solutions, previously more likely to be found in upmarket segments. No matter which engine the customer opts for, he is purchasing a vehicle with the best road performance in its class. It excels due to exceptionally low fuel consumption and complies with EU 4 emission standards.

In addition, the arrangement of the longitudinally mounted engines with the centre of gravity behind the rear axle makes a significant contribution towards achieving an ideal weight distribution. This arrangement also permits a surprisingly small turning circle of 10.7 metres (35 ft). The starter battery located under the luggage compartment floor assists in achieving a low centre of gravity and a further enhanced rear axle weight rating. Consequently, in addition to the elaborate suspension, the arrangement of the drive components is the decisive factor in achieving the BMW 1 Series’ exemplary agility and directional stability.

There is an option of two petrol and two diesel engines. All of them feature four-valve technology and were derived from the BMW 3 Series. Having been honoured with many international awards and featuring petrol engines with a maximum output of 55 kW, 60 kW in the case of the diesels, they represent state-of-the-art engine technology. They were slightly modified for use in the BMW 1 Series in order to further improve customer-relevant characteristics.

Petrol engines: power that is always there.
The BMW 120i engine: superior high-tech.
Of the petrol engines available, the BMW 120i produces the highest output and has a displacement of 1,995 cc. With variable valve timing incorporating VANOS variable camshaft control on both the intake and exhaust sides, as well as VALVETRONIC valve lift, it produces an impressive 110 kW/150 bhp at 6,200 rpm.

A maximum torque of 200 Nm is already obtained at 3,600 rpm. With this kind of power under the bonnet, the BMW 120i sprints from 0-62 mph in just 8.7 seconds. Top speed is an impressive 217 km/h or 135 mph, acceleration from 80 to 120 km/h (50 to 75 mph) in fourth gear comes in a mere 8.4 seconds. Given this engine’s impressive performance, an average fuel consumption of 7.4 litres over a distance of 100 kilometres can be considered a very good achievement overall.

A further increase in output and torque compared to the two-litre, four-cylinder engine in the BMW 3 Series, which is already considered a high performer, was achieved through an optimisation of details in the design of the intake and exhaust system. For example, the torque curve at full load for the BMW 120i engine in the lower speed range shows an increase of up to 23 Nm. Maximum output was increased by 5 kW. The engine was also improved in terms of response behaviour. Modified control unit electronics ensure a fast response when accelerating, something that was previously only achieved on engines with individual throttles.

This superior performance is underlined by a sporty, sonorous sound produced by the exhaust system which is never obtrusive, even when driving on the motorway and at high speeds. Each movement of the BMW 120i’s accelerator pedal also changes the intake and exhaust sound. The proverbial free-revving is not only visible on the rev counter, but can be heard as well. Furthermore, balancer shafts provide excellent running smoothness.

Thanks to the convenient start function, the engine is started simply by pressing the start button once. The control of starting procedure then continues automatically until the engine is turning over. A further enhanced comfort feature is the fact that it is no longer even necessary to open the bonnet in order to check the engine oil level. There is no longer a dipstick, instead the oil level is electronically recorded and displayed on the instrument cluster. The level is also consistently monitored when the car is on the move.

VALVETRONIC: a successful formula for lower fuel consumption.
The BMW 120i is equipped with VALVETRONIC fully variable valve control which enables remarkably low fuel consumption. First introduced on the new generation of BMW four-cylinder engines appearing on the market with the launch of the BMW 3 Series Compact in the summer of 2001, this technology is now utilised in the new generation of eight- and twelve-cylinder engines. Meanwhile, BMW has sold several hundred thousand vehicles worldwide featuring VALVETRONIC, thereby already making a valuable contribution towards a reduction in CO2 emissions.

Numerous international prizes, including the European environmental magazine award, are proof of the power of innovation and effectiveness of BMW technology in reducing fuel consumption. In contrast, lean mix direct injection engines have not been very successful on the market on a wide scale. To date, only some ten thousands of these engines offered by other manufacturers have been used in just a few models, which in addition are only available for use with sulphur-free fuel. As opposed to lean mix engines featuring direct injection, VALVETRONIC does not require sulphur-free fuel and a special catalytic converter. For this reason it is already being used worldwide and will play a significant role in future engine design.

The 116i engine: level-entry performance in top shape.
The BMW 116i engine is based on the BMW 120i high-tech power unit. With a displacement of 1,596 cc, the four-cylinder engine develops an output of 85 kW/115 bhp at 6,000 rpm and a maximum torque of 150 Nm at 4,300 rpm. The entry-level engine for the BMW 1 Series requires neither VALVETRONIC variable valve lift nor balancer shafts. It does, however, have all the other technical features of its big brother, including VANOS infinitely variable camshaft control. Thanks to these prerequisites, the BMW 116i is also capable of an impressive performance. It has absolutely no problem reaching the 200 km/h (124 mph) mark and accelerates from 0–62 mph in just 10.8 seconds. Despite this incredible feat, fuel consumption still remains low at 7.5 litres/100 km.
Diesel engines: Dynamics in their most economic form.
For some time now, diesel technology has boasted more advantages than just fuel economy. With their immense pulling force and a well-balanced development of output, modern diesel engines play an essential role in improving driving dynamics and comfort. BMW has made the most of this engine technology’s potential and optimised it for use in the BMW 1 Series.
The 120d engine: maximum pulling force.
The diesel engine featured in the BMW 120d is synonymous for state-of- the-art engine design. Having been featured in the BMW 3 Series, it has been modified for use in the BMW 1 Series. With a displacement of 1,995 cc, this engine develops an impressive 120 kW/163 bhp at 4,000 rpm. Its beefy torque of 340 Nm is produced at 2,000 rpm. The high output utilisation of 60 kW/82 bhp per litre of displacement is proof of the advanced stage of development of this engine. This high-tech machine has no trouble producing a road performance worthy of a sports car. It sprints to 62 mph in just 7.9 seconds, and the elasticity test, in which the car accelerates from 80 to 120 km/h (50 to 75 mph) in fourth gear, is passed after an exemplary 6.6 seconds. These figures are unparalleled in this vehicle class. Top speed is reached at 220 km/h (137 mph), and at the other end of the speed range immense power is already achieved just above idling speed.
Common Rail Injection: the latest technology for greater economy.
The modified second-generation Common Rail system with a pressure of 1,600 bar is chiefly responsible for superior acceleration, excellent dynamics, outstanding economy and compliance with EU 4 emission regulations. This system facilitates even faster fuel injection and vaporisation, directly resulting in increased performance and lower fuel consumption. As fuel is injected up to four times during each cycle (double pilot injection, main injection and after-injection), an optimum balance between performance and acoustics is achieved. Whilst the double pilot injection facilitates a smoother and more balanced combustion process, after-injection improves particle oxidation, thereby reducing toxic emissions. The new generation of turbochargers with variable turbine geometry, electric adjustment, optimised blade geometry, intercooler technology and the use of ultra-rigid, lightweight material further improve the effectiveness of the turbine and turbocharger compressor. Through these measures and by making modifications to the camshaft, pistons and connecting rod, it was not only possible to achieve compliance with EU 4 emission regulations, but also an increase in output of 10 kW/13 bhp compared with the familiar BMW 320d engine. Optimised exhaust gas recirculation, the position of the lambda probe in front of the catalytic converter situated in the proximity of the engine and swirl valves in the intake unit round off these measures and render this BMW four-cylinder one of the cleanest and most economical diesels in its segment. It is a particularly good example of how BMW is able to combine sporting qualities with economy and environmental compatibility.

With these features, the BMW 120d not only guarantees driving pleasure through superior performance and powerful acceleration, but also safeguards against unpleasant surprises at the petrol pump. With a remarkably low fuel consumption of just 5.7 litres/100 km, visits to the petrol station become a rare occurrence.

Compared with other diesels, the BMW 120d also excels due to refined running-smoothness. Electronic engine noise control and balancer shafts have reduced engine vibration to a minimum. Diesel combustion noise levels are so low that the driver has the impression of having a petrol engine under the bonnet. This also applies to a cold start, which is also possible at temperatures of minus 20 °C without any noticeable delay. The quick-start spark plugs begin to work as soon as the driver opens the door, and do not wait until the starter button is pressed. The system incorporates six-volt spark plugs which are heated only at the tip to maximum temperature. Thanks to the convenient start function, the starter button only needs to be pressed once to start the engine. The control of the starting procedure then continues automatically until the engine is turning over.

The 118d engine: powerful and effective.
As an alternative to the BMW 120d, less ambitious drivers have the choice of a second diesel variant, namely the BMW 118d. Whilst featuring the same technology, it produces an output of 90 kW/122 bhp and a maximum torque of 280 Nm from a displacement of 1,995 cc. The BMW 118d is also capable of turning impressive power output into sporty road performance. The little brother of the two BMW 1 Series diesel variants has a top speed of more than 200 km/h (124 mph) and manages the sprint to 62 mph in 10 seconds. Nonetheless, the BMW 118d can also be considered a prime example of modesty in terms of fuel consumption, which is just 5.6 litres/100 km.
Getting ahead in six stages: by hand or automatically.
The BMW 1 Series comes as standard with a six-speed manual gearbox (five-speed for the 116i). Thanks to the short-shifting gearbox and accurate guidance of the selector lever, changing gears is an effortless pleasure. The gearbox synchronisation also underlines the dynamic, sporty character of the compact BMW. Engine speeds after fast changes into the next gear are optimised. However, the higher gears have sufficient power reserves for accelerating without changing gear.

Due to a level of comfort within the entire speed range previously unknown in the compact class, the BMW 120i and BMW 120d are optionally available with the six-speed automatic transmission featured by the 5 Series. Just like the manual gearbox, this transmission was also provided with an optimum gear ratio suitable for all driving situations. Moreover, the six-speed automatic transmission excels due to extremely smooth transition between each gear. The sixth gear is designed to be a cruising gear in which top speed can also be reached.

As with all BMW automatic transmissions, the driver of a BMW 1 Series can also shift gears manually via the Steptronic function. Using this sporty operation gears are shifted simply by briefly flipping the selector lever. In order to activate this mode, it is only necessary to move the selector lever into the “+/–� direction. The gear currently engaged is displayed in the instrument cluster.

Servicing of engine and drivetrain reduced to a minimum.
No matter which engine the customer opts for, with the BMW 1 Series he is 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 elements. 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 which still has to be frequently carried out on other vehicles. Moreover, all transmissions have a lifetime oil filling.

After 30,000 kilometres at the latest, depending on how the car is driven, the driver is informed by the service interval display when a change of motor oil and filters is due. Prior to a long holiday, or at any other time, he can, if he wishes, obtain information on how long a wear part will last and then decide whether or not he wants to have it replaced before going on holiday.

Safety

All-round safety: The BMW 1 Series’ unique safety concept.
They do not need to be visible, but it is good to know they are there – the BMW 1 Series’ safety features are setting new standards in the compact class. The standard equipment encompasses all aspects of active and passive safety, which these days can make an effective contribution towards the prevention of accidents and the minimising of their potential consequences. This includes airbags, which, thanks to intelligent control with “decentralised intelligence systems�, provide the optimum measure of protection in the event of any kind of collision, and a suspension technology that guarantees the best possible level of control in any conceivable situation. In addition to this, the BMW 1 Series offers a myriad of safety features that are unique in the compact class and above.
Optimum protection, perfectly measured.
Six airbags serve as protection in situations not even an experienced driver can avoid. The BMW 1 Series comes as standard with two-stage activating airbags for the driver and front-seat passenger, side airbags sited in the side sections of the front seats as well as additional side head airbags which are accommodated in the roof lining. In the event of a side-on collision, these so-called curtain head airbags unfold in the shape of inflatable curtains and also protect rear-seat passengers from injury.

With regard to the activation of the driver and front-seat passenger airbags, we have observed the principle that less is often more. For this reason the airbag is activated in two stages, depending on how serious the accident is. What is more, in order to reduce repair costs the front seat passenger airbag is not activated if the seat is not occupied.

Electronic protection helps to prevent possible short-circuiting after an accident.
In the event of a collision further functions are also activated by an electronic protection system. These include opening the centrally locked doors and switching on the interior lights. In addition, the hazard warning lights are automatically switched on, the fuel pump and generator are immediately switched off and the battery safety terminal cuts off all other electric components from the power circuit. Consequently, the starter and generator cables are disconnected both electrically and mechanically from the positive pole of the battery in order to prevent short-circuiting and the risk of fire. The operation of all important functions, such as lights, hazard warning lights and telephone, is effected via an onboard power supply.
If the taillights fail: they are replaced automatically.
A helpful function for enhanced safety on the road is the BMW Light Control Module (LCM), which, for instance, in the event of the brake lights failing, supplies the taillights with increased power, a method by which the same signal effect is obtained as if the brake lights were functioning correctly. After being visually informed of the failure via the display, the driver has plenty of time to replace the defective parts but still has a completely roadworthy vehicle at his disposal. In the event of a failure of the taillights, the indicators or the rear fog lights, other lamps take over their respective function.
Please fasten your seat belts: comfortable and safe.
The BMW 1 Series features a belt system that simplifies the fastening of seat belts. Three-pivot seatbelts and headrests on all seats come as standard. Front seat restraint systems incorporating belt tensioners and belt force limiters provide a high level of comfort and functionality. The belt fasteners are mounted on the seat frame, which ensures that the belt position in the region of the hip remains the same even when the seat height is adjusted. The belt latch tensioners also featured as standard 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.
Intelligently reduced risk of injury.
If we are to continue optimising the protection of the head and torso, it is important not to forget the lower limbs. This was taken into account when designing the passenger cell of the BMW 1 Series. In the event of a head-on collision, the pedals swing away automatically, thus protecting the driver of a BMW 1 Series from foot and leg injury. The energy-absorbing footrest on the door side carries out a similar function. Thanks to this feature, the transfer of impact energy to the foot is reduced substantially. Furthermore, the steering wheel is designed to deform according to pre-defined criteria the moment the collision occurs, thereby reducing the risk of injury.
A safe place for children.
Room for children – inside the BMW 1Series there is enough of it to make children feel comfortable. The little ones are particularly safe on the child seats featuring the so-called ISOFIX fastening system. In the BMW 1 Series, the ISOFIX child seats can be fixed to the two outer seats at the rear and to the passenger seat at the front. The mounting points*, to which the child seats can be fastened quickly and safely, are already integrated in the vehicle. Moreover, the passenger airbag can be deactivated using a key switch, making it possible to use a child seat at the front that points to the rear.
The intelligent brake system.
The brake system of the BMW 1 Series is particularly powerful and can be applied in exact doses. Fitted with large brake discs at the front and rear wheels, the BMW 1 Series has the best deceleration rates of its class.

In addition to being efficient, the brake system should, above all, be100 percent reliable. On the BMW 1 Series, the brake system features yet another innovative function: a brake pad wear indicator which constantly informs the driver of the brake pads’ state, doing away with the need for unnecessary checks at the garage. This job is done by sensors in conjunction with a control unit, which automatically calculates when the brake pads should be changed next. For its prognoses the control unit takes into account not only the wear the brake pads have been subjected to, but also the driving behaviour. The BMW 1 Series’ continuous brake pad wear indicator is another safety feature which is unique in the compact class.

More driving fun, more control, more safety: the BMW driving stability systems.
The chassis and the suspension, which have high reserves, the precise steering and the brake system, which can be applied in accurate doses, constitute the basis for the BMW 1 Series’ unique combination of driving pleasure and safety, which is complemented by the DSC Dynamic Stability Control. DSC Dynamic Stability Control is a standard feature of the BMW 1 Series and aids both dynamic handling and safety. This system makes ventures beyond the suspension’s limits, which are extremely high, much less risky, preventing the vehicle from swerving out of control by applying the brakes to individual wheels and, if necessary, reducing engine power. Particularly when performing abrupt evasive manoeuvres or driving on slippery surfaces, DSC helps to master critical situations and to make the necessary course correction.
Excellent forward thrust thanks to DTC.
With the push of a button, the sports-minded driver can activate the so-called DTC mode of the BMW 1 Series’ DSC function, which is activated whenever the engine is started. The DSC’s DTC mode (DTC = Dynamic Traction Control) improves traction on snow, loose or dry surfaces. DSC remains active but the upper slip limits are higher, and the control system only cuts in when the defined threshold is exceeded.

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: It is no good if the suspension is dependent on the use of an electronic system.

Perfect stability when taking bends and applying the brakes.
ASC Automatic Stability Control, which is integrated into DSC and has the same function as a mechanical differential lock, helps the driver to set off smoothly in deep snow, on off-road tracks and on slippery uphill gradients. Finally, CBC Cornering Brake Control provides even more safety and driving dynamics. This system is activated long before ABS cuts in and stabilises the car when the driver applies the brakes in bends by slightly reducing the brake pressure on the inner front wheel and the rear wheels. Thus, the system counteracts any inclination of the vehicle to spin around when the driver applies the brakes when cornering. In addition to this, EBD Electronic Brake Force Distribution ensures the optimum distribution of brake forces irrespective of the load. DBC Dynamic Brake Control is an extension to the DSC and ABS stability control systems.
Punctures? No reason for concern.
Two further safety features prevent the dangerous consequences a slow or sudden loss of pressure in the tyre might have. The tyre defect indicator in the BMW 1 Series’ cockpit informs the driver of a loss in pressure, which might cause dangerous situations if no remedial action is taken over a longer period of time. BMW accident research shows that 80 percent of all punctures could be avoided as they are preceded by a slow loss in pressure which can be rectified without changing tyres. The BMW system detects all these risk situations at an early stage. The tyres’ pressure level is constantly monitored by an intelligent system evaluating the wheel speeds on all four wheels. The necessary data is provided by the ABS sensors. If the actual values deviate too much from the set values, a warning signal is triggered.
Arriving safely even with a flat tyre.
In the case of a tyre defect which leads to a partial or complete loss of pressure, the driver of the BMW 1 Series can proceed with no problem at all to the nearest garage, provided he or she drives carefully and at an appropriate speed. The BMW 1 Series features tyres with emergency running properties which bring the BMW 1 Series reliably and safely to the desired destination even in the event of a “flat�. State-of-the-art technology allows the driver to continue for up 150 kilometres or 93 miles without any pressure in the tyre. This technology contributes considerably to safety in case of a tyre defect at high speeds. By and large, drivers of the BMW 1 Series no longer have to fear this accident-prone situation thanks to the tyres’ special design and structure. Even if a tyre suffers from a sudden and complete loss of pressure, it does not jump off the rim, making the vehicle controllable even in case of a “blow-out�.

The fact that wheels do not have to be changed on blind spots or dangerous stretches of road further adds to safety.

BMW is the world’s biggest supplier of cars fitted with runflat tyres.

The body: more room for enhanced safety.
How safe the passengers in a vehicle feel is not just dependent on the driver’s style of driving. The BMW 1 Series conveys a feeling of safety which is unparalleled in the compact segment. The body’s quality fully lives up to the high standard so typical of BMW brand vehicles. Every single body component excels due to stability, fitting accuracy and high-quality finishing. This ambience is in keeping with the promise BMW now also fulfils in the compact class. The use of high-strength steels in conjunction with extensive support structures and selectively designed reinforcements make the body extremely rigid. The robust structure helps to keep the vehicle on track even in critical situations, whilst the body’s high level of torsional stiffness contributes greatly to the vehicle’s agile handling, precise steering and outstanding safety. The BMW 1 Series ensures a safe drive even in the most demanding situations, its excellent driving dynamics making a valuable contribution to active safety.

In addition, the 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 all conceivable crash situations have been analysed with attention to the smallest detail. The result: featuring an extremely stiff passenger cell combined with perfectly harmonised support structures and deformation zones, the BMW 1 Series offers optimum protection to its passengers under all conditions, a further feature which is quite unique in the compact segment.

Maximum protection in all crash situations.
The forces acting on the vehicle in the event of a head-on collision are passed on to the deformation zones via precisely calculated, predetermined channels. This ensures that the energy, which is diverted from the front end’s supporting structure, is absorbed before reaching the passenger cell. The whole system aims at isolating occupants in the passenger cells from the influence of deformations in the case of a crash and to utilise the restraint systems, that is the airbag and safety belt, to protect them from the consequences of a collision.

Extremely resistant doors with high-strength side impact beams and safety latches, a reinforced B-pillar and the instrument panel between the A-pillars guarantee exemplary stability, should the BMW 1 Series be involved in a side impact. Also, the roof frame and the body platform have been designed in such a way as to protect the passenger cell. The same applies to the rear deformation zone, where longitudinal members, the side panels and the luggage compartment floor, together with various reinforcements, ensure that the impact energy is diverted and absorbed without having an adverse effect on the passenger cell. Moreover, the extremely rigid pillars and crossbeams provide the occupants with maximum protection in case of a rollover.

Featuring a wide range of safety equipment, the BMW 1 Series has got what it takes to win 5 stars in the Euro NCAP crash test.

Equipment: In Extracts

Carried over from the luxury performance segment: the equipment of the BMW 1 Series.
With the BMW 1 Series, BMW redefines driving dynamics, safety and functionality in the compact class. This compact BMW is fitted with a range of standard features which are quite unusual in this segment. The BMW 1 Series’ equipment is characterised by premium quality and technological innovations. Numerous features of the BMW 1 Series, which considerably enhance both functionality and driving comfort, have so far been exclusively used in upmarket cars. In addition, the BMW 1 Series boasts a number of technological innovations which have never been seen before in the automotive industry.
The seat concept: quality and high-tech for increased comfort.
The seats of the BMW 1 Series completely live up to the expectations of the sporty driver and, at the same time, ensure optimum comfort on long-distance journeys. The seats can be adjusted to many different positions, providing an optimum seating position no matter what your size. The steering column is horizontally and vertically adjustable. A four-way lumbar support* helps to relieve the strain on the spinal column. The volume of the side sections can be pneumatically increased or reduced* to give optimum side support to people of all sizes, a feature which has so far been used exclusively on particularly sporty vehicles, such as the BMW M3.

Additional comfort on cold days is provided by the seat heating integrated into the driver and passenger seat. The special thing about this feature of the BMW 1 Series is that the entire seat area and backrest are heated, giving the driver and his passenger an instant feeling of comfort.

Climate control: comfort with the push of a button.
One thing is for sure: driving the BMW 1 Series will make your heart skip a beat. Without a doubt, the new BMW is emotional. Above all, drivers who prefer a sporty style of driving will be looking forward to every bend in the road. It is no problem at all, however, to “stay cool� in the BMW 1 Series thanks to a sophisticated climate control system. When designing the ventilation, heating and air-conditioning systems for the BMW 1 Series, much attention was paid to outperform the features previously used in the compact class, thereby accentuating the premium character of the equipment. The dimensions of the air-ducting components, filter systems and heating and cooling systems were developed to provide the fastest heat-up and cool-down rates of their class and are highly efficient at the same time. An optimised air ventilation system and an elaborate control technology provide highly effective, precisely adjustable, homogeneous, draught-free, low-noise temperature control. The fresh air, drawn in by means of a micro filter, is brought to a specified temperature, dried and distributed to the air outlets in accordance with the selected setting. Depending on the desired temperature, the incoming air is partially or fully supplied to the heating or cooling aggregates, thus enabling a quick, flexible and draught-free temperature change and creating a pleasant climate inside the BMW 1 Series no matter what the season.

Automatic air recirculation, which is integrated into the climate control*, prevents pollutants from entering the vehicle’s interior. The system identifies pollutants, such as carbon monoxide, nitrogen oxide and ethanol. If the pollutant concentration reaches a certain limit, the automatic climate control temporarily switches over to recirculation mode.

Independent of the temperature outside and air humidity, the air ventilation control effectively prevents the windows from misting up. To achieve this, a so-called “dew point sensor� has been integrated into the climate control, a feature which has been previously exclusive to upmarket vehicles. Vehicles with a diesel engine are fitted with an auxiliary heating system which effectively heats up the interior on cold winter days shortly after the engine has been started. BMW’s automatic climate control* is combined with a temperature control system that enables separate adjustment for the driver and the front seat passenger. The control system also takes into account the current degree of insolation. In terms of efficiency, prevention of draught effects and acoustics, the heating and climate control system featured by the BMW 1 Series sets a new, unprecedented standard of comfort in the compact class.

The control concept: a clear division between primary driving functions and secondary functions.
The cockpit of the BMW 1 Series is clearly divided up into a driving zone and a comfort zone. Thanks to the ergonomic arrangement of the functional elements and the use of as few buttons and controls as possible, the cockpit features a harmonious and clearly structured design focusing on the essentials. The design of the indicators and controls facilitates a simple and intuitive use of all functions without distracting the driver from his important task of driving. A glance at the round dials reveals which aspect has been given top priority – namely driving pleasure.

The road speed, engine speed and all other information essential to driving are displayed on the instrument cluster. The display between the round dials provides data from the onboard computer and information on the oil level or service intervals, which can be retrieved by the driver by operating the steering-column switches and paddles. The multi-function steering wheel* enables the driver to operate individual comfort features without taking his eyes off the road. For example, the driver can use the buttons on the steering wheel to operate the audio* and telephone system* and to activate the climate control’s recirculation mode*.

Furthermore, the comfort zone’s control units on the centre console are ergonomically arranged. The functional elements for entertainment and climate control are to be found on their own, clearly separated levels within the comfort zone, thus providing a clear structure. The controls for operating the air-conditioning, entertainment and navigation functions can be easily accessed by the front-seat passenger, enabling him to act out his role as co-pilot, whilst the driver is able to fully concentrate on the road and traffic around him.

Everything under control: the optional iDrive* control concept.
When the BMW 1 Series is ordered with a navigation system, the groundbreaking iDrive control concept is included in the equipment. iDrive facilitates the operation of numerous secondary vehicle functions, which are not needed on a permanent basis. This previously required a bewildering number of gauges, switches and buttons. The BMW 1 Series’ well structured menu on a large colour display and intuitive operation make it child’s play to use the system. The central element is a controller on the centre console. By turning, pressing or sliding the controller in one of four directions, the driver – and also the co-pilot – are able to go through the menu and select the desired options. The driver does not have to tilt his head to look at the control display. He just has to turn his head slightly to the right. As opposed to conventional systems, which require the driver to find and operate a switch on the centre console and to finally look for a telltale somewhere on the dashboard to check if his command has been carried out, iDrive is a quantum leap in terms of intuitive operation, reduced distraction and increased safety. A button in front of the controller enables the operator to return immediately to the main menu at all times.

All functions pertaining to communication, navigation, entertainment and climate control as well as individual vehicle settings can be activated via iDrive. The selected menus, functions and settings can be seen on the control display above the centre console. The graphic arrangement of the menu options on the display corresponds to the movements of the control knob, thereby guaranteeing the intuitive selection of functions and settings at all times. Audio functions, which are frequently used, can also be accessed via buttons on the centre console and – provided this equipment option has been chosen – the multi-function steering wheel*, even if the car is equipped with iDrive. The air-conditioning* system’s basic functions, that is the selection of the temperature and the blower level, can also be controlled using alternative, conventional switches and buttons. The fine-adjustment, however, is made via iDrive.

BMW voice entry.
BMW voice entry* is a complement to the iDrive operating concept. The driver can alternatively use voice commands for operating a host of radio, CD, navigation and, in particular, telephone functions. The system excels due to intuitive dialogues and does not need to be trained or adjusted to the driver’s voice. The system is able to identify about 400 words, typical voice commands being, for example, “Redial�, “Dial 0893820�, “Route guidance on� or “CD number 1�. Moreover, names of radio stations and telephone directory entries can be directly accessed and activated.

The voice entry system is designed in such a way as to allow further functions to be added via a software update.

The engine starter button: driving pleasure with the push of a button.
All engine and equipment variants of the BMW 1 Series are fitted with an engine starter button, which is located on the dashboard directly adjacent to the steering wheel. All the driver has to do in order to activate the start function is to insert the bitless radio key into the hole provided. The driver does not have to turn the key in the ignition. Instead, he presses the starter button, a procedure, which is reminiscent of that found on and previously reserved for thoroughbred sports cars such as the BMW Z8. Now the BMW 1 Series also sports this feature. The push of the starter button impressively provides a taste of the driving pleasure to come and accentuates the importance BMW places on the power unit, also in the compact class. When pressing the starter button, the driver of vehicles with a manual gearbox must simultaneously step on the clutch pedal. When starting an automatic, the brake pedal has to be actuated. On automatics, the start and the stop functions can only be activated when the selector lever is in the “P� position.
Driving without a key.
The innovative starting procedure is particularly user-friendly when mated to the Comfort Access feature, enabling the driver to access the car without a key. A transducer in the key automatically unlocks the doors as soon as the driver with keys approaches the car and operates the door handle. In this case, the engine of the BMW 1 Series can even be started without inserting the key, this meaning that the driver, having unlocked the door, can leave the keys in his pocket. The comfort access feature “recognises� that the key and the driver are “onboard� and the only thing the driver has to do in order to start the ignition is to press the starter button.

The exchange of signals between the key and the vehicle even goes one step further: as soon as the vehicle is opened with the driver’s key, the electrically adjustable seats*, the exterior mirrors, the air conditioning* and the audio system* are adjusted to suit the key owner’s preferences. In addition, the key stores the illumination (low-beam headlights always activated, setting the ‘follow me home’ lighting function ...) and central locking (automatic door locking when starting, turn-signal when locking the car, ...) settings selected by the key owner the last time he or she drove the car.

By using this memory function, the BMW 1 Series can identify each driver by his or her key and give him or her an individual “welcome�. This feature increases comfort considerably, particularly on vehicles that are used by several different drivers.

If, for example, your son or daughter was the last person to use the car and turned up the audio system’s volume deafeningly loud, the next driver will not get a shock as the radio instantly plays at the volume that person has last chosen. Nor will you have these situations where you have to sit cramped behind the steering wheel because the person who used the car before you was smaller and moved the seat far forward.

Always ready to start thanks to an intelligent battery sensor.
The BMW 1 Series’ constant reliability is not only attributable to the use of high-quality materials and meticulous finishing, but also to clever ideas, one example being innovative power management, which we are already familiar with from upscale BMW vehicles. The intelligent battery sensor (IBS) permanently monitors the battery’s state of charge. In situations where the battery is too low there are two ways to intervene: first of all, the idle speed automatically rises to speed up the charging of the battery. If this measure alone does not suffice, less energy is supplied to gadgets which are not necessarily needed. This measure temporarily reduces comfort but ensures that enough energy is supplied to the engine when it is started next. The power management eradicates one of the most frequent reasons for breakdowns – engine failures due to a flat battery.
Full of ideas, practical, innovative: the interior.
Apart from the technological innovations, it is often the practical things which make everyday driving more comfortable. Not only has the BMW 1 Series particularly agile driving characteristics, it has also a generously-spaced interior, which is versatile in use and offers abundant equipment details. Four doors and a rear lid which swings open wide (to a height of 1.8 metres or 6 ft) provide easy access to the rear seats and luggage compartment. The asymmetrically split folding rear seats give the BMW 1 Series the utmost flexibility. The transport concept also includes a ski bag module* in the middle of the seat back. The ski bag can be removed and exchanged, for example, for a storage compartment with cup holders*. A luggage compartment net* prevents luggage stored at the rear from intruding into the passenger compartment when the driver slams on the brakes.
Plenty of storage space for odds and ends.
The centre armrest* with a practical storage compartment underneath it is, from an ergonomic point of view, ideally positioned between the front seats. The glove compartment with a volume of 7.4 litres is generously sized. A host of storage spaces at the front and rear and storage nets* on the back of the front seats, hooks* for shopping bags, a power socket* in the luggage compartment and an additional compartment underneath the boot floor provide added functionality. The latter is supplied instead of a spare wheel well, which is no longer necessary as the car is equipped with runflat tyres.
All important information at a glance: the onboard computer display.
Apart from providing classic information on time, date, outside temperature, average speed and fuel consumption, the onboard computer, which comes as standard, tells the driver when the car has to be serviced next and informs him of possible malfunctions. All petrol-engine versions of the BMW 1 Series feature a thermal oil level sensor, doing away with the need for a dipstick in the engine compartment. The oil level is now checked with the push of a button, making dirty and cold hands a thing of the past. The oil level can also be queried while driving. The driver can see the measuring result on the instrument cluster.
Parking made easy.
The PDC* Park Distance Control offers the driver increased comfort and safety when parking. Sensors at the front and rear end of the vehicle detect obstacles, which are in the way when the driver tries to get into a parking lot but are out of normal vision. In this case, the driver will hear a warning tone, the frequency of which increases as the driver approaches the obstacle. The signal leaves no doubt: as soon as the driver hears a continuous tone, there is not much room for manoeuvre left. In addition to this, the driver can see the vehicle’s position in relation to the obstacle on the iDrive control display*.
Top-class audio systems*: HiFi on the move.
Listening to chart breakers on the radio or to your favourite song on CD – all this is possible in the BMW 1 Series, which offers not only the ultimate in driving experiences but also a very special sound experience. The basis of this is constituted by a system with six high-quality loudspeakers, two of which are high-volume woofers and centrally located under the front seats. The woofers use the cavity in the door sills as a sound body to improve the reproduction of bass sound, and provide, even in conjunction with the entry-level radio, optimum audio quality. Further audio options include a 9-channel digital amplifier, a CD changer and the LOGIC 7 professional sound system, these being optional extras which fulfil the needs of the most discerning customers. All radios* also have an aux input. On the whole, the BMW 1 Series certainly offers the most sophisticated audio system of its class.
MOST: data communication by means of optical lightwave conductors.
To ensure fast and reliable data communication for the HiFi system and all other communication and multimedia components, the BMW 1 Series is kitted out with the MOST optical data bus, which has been especially developed for use with audio systems. A further advantage of this technology is that additional communication devices can be easily retrofitted and networked with each other. As data is communicated using the already existing optical lightwave conductor ring system, components do not have to be wired individually. When activating a hands free kit, for example, the exchange of signals between the mobile phone, the Bluetooth interface, the control display and the radio is masterminded by the ring system of the MOST data bus. Optional extras, such as the head-up display or a CD changer, can therefore be easily integrated into the MOST system. BMW has made its name as a pioneer in the development of these data communication systems. Meanwhile, a multitude of car manufacturers have become involved in the further development of this technology. Using the MOST technology in a compact class car, BMW once again strengthens its position as a technological frontrunner in this field.

Cost of Ownership

Much less time for maintenance – more time for driving pleasure.
One of the top priorities in the development of the 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 the compact segment which requires less service and maintenance than the BMW 1 Series.

The technology used for the engine and drive is exemplary for the BMW 1 Series’ reduced service and maintenance requirements. BMW has set new standards in the compact class, utilising sophisticated technologies which make many parts and components of the BMW 1 Series maintenance-free.

As the camshaft on BMW vehicles is driven by a chain which is maintenance-free during the vehicle’s entire life cycle, there is no need to change a toothed belt, a job which even today has to be carried out on the majority of compact class vehicles every 60,000 to 120,000 kilometres. Moreover, there is no need for valve adjustment, a rather time-consuming job, as the BMW 1 Series features hydraulic valve-play compensation. On the BMW 1 Series, poly-V-belts are used for driving the alternator, the hydraulic pump and water pump, which consequently do not have to be replaced.

Also, the BMW 1 Series’ transmission requires hardly any maintenance. This applies both to the manual gearbox and the six-speed automatic transmission. All gearboxes have a lifetime oil filling. The exhaust system is also one of the components requiring regular maintenance and repair work on many vehicles. This is not the case with the BMW 1 Series: its exhaust system is completely made of stainless steel.

Service intervals depend on how hard the car is driven.
In the 1982 model year, 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 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. The central idea behind this concept is that sensors and sophisticated software algorithms constantly monitor selected parts and components subject to wear and tear. This enables the customer to use his 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 next.

An enhanced use of service limits combined with a reduction in maintenance times has ushered in a new era in vehicle service and maintenance. CBS also tells the driver when the next technical inspection (e.g. TÃœV) or exhaust test (AU) is due.

Better planning of service appointments.
The aforementioned concept makes vehicle servicing much more transparent for costumers. If, for example, the owner of a BMW 1 Series plans to go on a longer journey, he can independently determine whether he has to have the car serviced before the journey or if there is enough time to wait until after his return. He can thus easily prevent situations where, for example, the brake pads suddenly have to be replaced in the middle of a journey. 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 which 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 servicing. 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 so-called key-reader, the information stored in the key, such as mileage, vehicle identification number, initial registration date, colour, upholstery and equipment codes and, of course, 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 bumping slightly into the car in front are a nuisance. The BMW 1 Series’ reversible bumpers prevent unnecessary costs in a bumper-to-bumper collision at a speed of up to 4 km/h or 2.5 mph. 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 or 9 mph, these elements prevent all damages to the structure. In development, much attention was actually paid to avoiding expensive repair work on damaged body parts. The effectiveness of all these measures is proven by the fact that in Germany the BMW 1 Series has been given a favourable insurance classification.

Jump-starts are no longer necessary.
BMW even made provisions to prevent situations where there is not enough energy left to start the engine. If the electrical devices consume too much energy, an intelligent battery sensor (IBS) deactivates them one after the other, thereby ensuring that there is enough energy left when the engine is started next. In addition, this contributes to lower operating costs, as the driver of the BMW 1 Series saves costs caused by necessary jump-starts.
Enough energy even for the remote control.
Perfection down to the smallest detail is also demonstrated by the remote control key: in contrast to most other systems available on the market, this key does not incorporate a conventional battery. Instead, it has an accumulator which is constantly loaded via the ignition lock, doing away with the need to replace an expensive battery after a few years.
Typical BMW: the same warranty as a big one.
BMW’s efforts to keep the costs of ownership as low as possible are rounded off by a 12-year warranty against rust and corrosion. There is a 3-year warranty on the paintwork and a lifetime mobility guarantee.

Sales

Changes in equipment possible up to eight days prior to final assembly.
There is no denying that the BMW 1 Series is unique but, in addition to this, every single vehicle is truly special. A wide range of equipment options and colours, upholstery options and interior trim lines enable customers to create their very own BMW 1 Series. The probability of two identical BMW 1 Series vehicles leaving the factory within one year is virtually nil.

Although choice is abundant, delivery times are short and reliable. BMW introduced the customer-oriented sales and production process (KOVP) in order to handle orders quickly and with the utmost precision. Thanks to this process, which also involves external suppliers in overall logistic planning, requests for changes can be taken account of up to eight days prior to the start of final assembly.

BMW fulfils customer wishes more flexibly than ever before.
Never before has a compact class vehicle featured such attractive equipment details, the options ranging from different engines, exterior paints, interior trims, upholstery designs, right through to a host of varying wheel sizes. The possibilities for personalisation seem to be unlimited, making it quite difficult for customers to make up their mind. This is why BMW now leaves customers more room for spontaneous decisions. Have you changed your mind and decided to opt for a glass sunroof? Or has the navigation system with dynamic route guidance moved to the top of your wish list? Has your dream colour changed from black to silver? The final configuration of the vehicle ordered can now be undertaken much later than previously. The so-called flexibility for changes used to be greatly restricted and alterations were not possible within the six weeks preceding the start of final assembly. On the BMW 1 Series, however, requests for changes can be taken into account up to eight days before the commencement of final assembly thanks to the customer-oriented sales and production process.
The production of the BMW 1 Series: a logistic stroke of genius.
These customer-friendly processes call for a high degree of coordination. A good example of this is the just-in-sequence production of the seats by the supplier Lear at its Wackersdorf facility. The seats desired by the customer are ordered shortly before the commencement of vehicle production. Nevertheless, there is enough time to adjust production accordingly. There is not much scope left, however, for the following processes:

The time span between producing the seats at the Wackersdorf facility and fitting these into the vehicle at the Regensburg plant is only six hours. In all, 21 so-called part families are produced and delivered utilising the JIS principle, which calls for constant logistic accuracy and enables suppliers to adapt production to meet specific demands and to make better use of transportation capacities.

Online requests: when will final assembly start?
A further advantage for dealers and customers is that the KVOP process supports the service-oriented placement of online orders. For quite a while customers have already been able to configure their vehicles online and to send the order data via PC to the production plant. Thanks to KOVP, dealers and customers will be able to in future retrieve order status information at any time. Thus customers will increasingly look forward to their new BMW 1 Series. In addition, they will always be up-to-date, knowing the number of days left until changes to vehicle details are no longer possible.

Production

The BMW 1 Series production at the Regensburg plant – commitment to Germany as an industrial location.
The production of the new BMW 1 Series at the Regensburg plant will commence in the summer of 2004. The decision to produce the BMW 1 Series at the BMW facility in East Bavaria reaffirms BMW’s commitment to Germany and creates new jobs. The Regensburg plant has been expanded and adapted to cater for increased production. So far, numerous variants of the BMW 3 Series have been produced at Regensburg, many of which will continue to be manufactured there.
Innovations for the production of the BMW 1 Series at the Regensburg plant.
Many different production methods are used in the production of the new BMW 1 Series, be it in the body shop, the paint shop or in the assembly of individual components. The Regensburg plant’s assembly lines have been ergonomically improved even further in the run-up to the start of production of the BMW 1 Series. These innovations help to make production more efficient, contribute to environmental protection, create a healthy environment for the staff and, last but not least, ensure a high level of quality in vehicle production.
Powder instead of varnish.
It has been a long time since BMW started to use water instead of hydrocarbon as a solvent in vehicle painting. The method of applying the top coat to the BMW 1 Series is unprecedented in vehicle production. The so-called clear coat is the last functional layer of paint, which, applied as a powder clear paint, is 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 water is generated in the process. Chemical agents for cleaning the painting facilities are 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.

“We use our know-how not only for creating automotive innovations but also for developing outstanding, powerful production technologies. The example of powder clear paint clearly shows that the BMW Group is a technological frontrunner when it comes to sustained production and a careful use of resources�, says Norbert Reithofer, head of production at BMW AG.

Accuracy at its best: the engine is automatically bolted on to the transmission.
For the first time in the world, the transmission is attached to the engine block by means of robots. In order to use this technology for the production of the BMW 1 Series, 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. With a tolerance of only 0.15 millimetres, the precision of this new method is simply incredible.
The cockpit: assembled by hand, installed by robots.
Another innovation in the production of the BMW 1 Series is the installation of a pre-assembled cockpit module by means of robots, this being a method, which has never before been put into practice. As a first 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 is advantageous as it 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.
Production cells for increased flexibility in the body shop.
The body shop concept “Mobi-Cell�, an in-house development which stands for “Mobile Standard Production Cell�, is also quite remarkable. Using this concept, body shop production cells can be relocated quickly and at low costs. Individual cells can, for example, be combined in order to create bigger and more complex production stations.
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 Series and 3 Series production has been optimised. The assembly areas are kitted out with a height-adjustable moving floor which is 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 needed.
The history of the Regensburg plant.
Vehicle production at the Regensburg plant commenced back in November 1986. In 1995, as many as one million vehicles had been produced at Regensburg. 1997 saw the completion of the press shop. The groundbreaking ceremony for the Wackersdorf innovation park took place in 1998. In the same year, the 8,000th associate took up work at the Regensburg plant. In 2001, the two millionth BMW vehicle rolled off the Regensburg production line. The Regensburg plant, which extends across an area of 140 hectares, currently has a staff of 10,000; 300 of which are apprentices. In Germany, Regensburg is one of three BMW sites devoted to the production of automobiles. With a production volume exceeding 237,000 automobiles in 2003, it is the second biggest plant within the worldwide BMW production network.

Recycling

If, after many years of usage, the lifecycle of the BMW 1 Series comes to an end, this car once more proves to be the perfect choice: when developing the BMW 1 Series, the designers attached great importance to economical disassembly to ensure recyclability of a high percentage of vehicle components. Right from the outset, recycling specialists were involved in the development of the BMW 1 Series with a view to later recyclability. Already today, the BMW 1 Series complies with EU legislation which 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 being the BMW 1 Series’ bumper panels. Although they are made of one single material, which is not the norm these days, they meet all functional safety requirements. The BMW 1 Series is a good example of what is feasible to deal with the trade-off between weight- and space-saving compounds, on the one hand, and the use varietally pure material for better recyclability on the other.

Recyclability down to the smallest detail.
When devising the safety and drive-relevant components for the 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. The only thing which 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 components having their own fluid system (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.
