DSC Dynamic Stability Control for superior handling in critical situations.
With the chassis being absolutely neutral and well-balanced in its set-up, the new BMW 1 Series keeps steadily on course even when driving to the extreme limit. DSC Dynamic Stability Control featured as standard comprises functions such as ABS anti-lock brakes and ASC Automatic Stability Control preventing the drive wheels from spinning while the car is accelerating.
The Brake Assistant, in turn, ensures maximum brake pressure whenever the driver requires a particularly high level of stopping power, and CBC Cornering Brake Control also integrated in the DSC system stabilises the car when applying the brakes in a bend.
In extreme cases – for example when avoiding an obstacle suddenly looming up in front of the car – electronic DSC Dynamic Stability Control enables the driver to handle the car safely in a smooth and superior process. DSC thus prevents the car from oversteering or understeering, simply by applying the brakes specifically on individual wheels and reducing engine power as required. In the process DSC intervenes smoothly and efficiently only when there is a risk of the car exceeding the limits to diving dynamics, without in any way impairing the dynamic driving characteristics of the BMW 1 Series.
DTC Dynamic Traction Control is a sub-function of DSC serving to provide optimum traction and drive power. The particular feature of this system is that it allows higher slip on the drive wheels than with DSC, thus enhancing the car’s grip and traction on slippery surfaces such as deep snow. A further point is that in the DTC mode the car’s electronic management intervenes at a later point in time when the vehicle is unstable, enabling the skilled driver to choose a higher level of lateral acceleration and take bends in a controlled power slide, driving the vehicle to its extreme limit. And last but not least, the driver is also able with DTC to completely deactivate the stability control function.
In the new BMW 130i DSC offers an even wider range of additional functions including a Start-Off Assistant and automatic Brake Pressure Compensation whenever the brakes reach an extremely high temperature and thus preventing any fading of the brakes in the process. Pre-loading of the brake pads whenever the driver suddenly lets go of the gas pedal and therefore indicates that the brakes must be applied instantaneously with maximum power serves to minimise stopping distances in such a situation. The Dry Braking function, in turn, improves the effect of the brakes in the wet, with the brake pads being moved slightly towards the discs at regular intervals to remove any film of water on the discs.
The Soft/Stop function enables the driver to bring the car to a halt in a particularly soft and smooth process, controlled reduction of brake pressure preventing a sudden jolt of the vehicle before coming to a standstill. In conjunction with Active Steering, the DSC system is also able to build up an appropriate countersteering effect, preventing the car from swerving, for example when applying the brakes hard on surfaces with varying frictional coefficients.
Yet a further improvement is that DSC Dynamic Stability Control in the new BMW 1 Series comes complete with an integrated wear indicator for the brake pads. Offering BMW’s Condition Based Service (CBS), this electronic control system takes the data measured to calculate the remaining mileage until the brake pads have to be changed.
The BMW 1 Series comes as standard on runflat tyres enabling the driver to keep on driving even with a completely flat tyre. Indeed, runflat tyres allow an ongoing range of at least 150 kilometres or 93 miles at a speed of up to 80 km/h or 50 mph.
Yet another feature standard in the BMW 1 Series is the Tyre Defect Indicator permanently monitoring air pressure in all wheels and warning the driver through a signal in the instrument cluster as soon as tyre pressure drops more than per cent below the ideal level.

Six airbags and innovative lights technology for enhanced safety.
The safety concept of the new BMW 1 Series is based on a stiff and stable body structure taking up forces in the event of an accident through precisely defined load paths and keeping the passenger cell stable and intact. Highstrength steel, additional reinforcements and special deformation elements serve to fulfil all statutory requirements and standards applicable in markets the world over.
Six airbags featured as standard ensure optimum occupant safety and protection: the frontal airbags inflate in two stages, depending on the severity of a collision, while side airbags integrated in the front seat backrests reduce the risk of injury on chest and hip level in a collision from the side. Curtain/ 30 head airbags integrated in the roof lining, in turn, protect both the driver and front passenger as well as the passengers at the rear from a side-on impact.
All seats come with three-point inertia-reel seat belts and headrests, and the front seats are fitted additionally with belt latch tensioners and belt force limiters. Driver pedals moving back in the event of an impact, finally, serve to minimise the risk of foot injury for the driver.
In the interest of safety in general, the new BMW 1 Series features a daytime lights function provided by the corona rings in the double round headlights incorporated in the bi-xenon headlight package available as an option. Daytime lights enhance the visibility of the vehicle and, in this specific case, add a look typical of BMW, the striking corona rings showing clearly from the start that this new compact model is a genuine BMW in every respect.
The BMW 1 Series also comes as an option with BMW’s Adaptive Headlights guiding the main headlight beam in the same direction as the steering wheel for optimum illumination on winding roads. This function is provided by a special mechanism moving the bi-xenon modules in accordance with the car’s steering angle, lateral acceleration, and road speed. And yet a further function is dynamic control of the headlight range.
Yet another innovative feature boasted by the BMW 1 Series is the Bending Lights function. Following the same principle as the Adaptive Headlights, this function is activated at speeds of up to 40 km/h or 25 mph, turning the headlights to their extreme position facing fully left or fully right whenever required. The big advantage is that when the driver turns into a dark side road, the route he is taking will immediately be illuminated, offering the driver optimum visibility from the start.
The brake lights on the new BMW 1 Series operate in two levels of brightness as a function of brake pressure. This gives motorists following from behind a clear and immediate signal, showing them that the driver is applying the brakes particularly hard for maximum stopping power. With the illuminated area in the brake lights being enlarged in such a case, motorists following from behind will automatically be induced to brake harder, too.
With its refreshed design, enhanced product substance and innovative engine technology, the new BMW 1 Series fits perfectly into BMW’s model range.
So offering driving dynamics, motoring safety and enhanced economy typical of BMW, the new BMW 1 Series once again sets the standard in the compact car segment.

Exclusive production in the BMW Leipzig plant.
The new three-door BMW 1 Series is exclusively manufactured in the BMW Leipzig plant. Just two years after the inauguration of the new plant and the successful commencement of mass production of the BMW 3 Series Saloon, the plant in Leipzig – like almost all BMW vehicle plants – is producing a second model. From the outset, the site was designed so that new models can be integrated without interrupting ongoing production. The Leipzig plant demonstrates this impressively with the present start of the new BMW 1 Series: The preparations for starting the new model in the bodywork construction shop, in the paint shop and the necessary expansion measures in assembly were carried out during running operation. BMW 3 Series and BMW 1 Series are now manufactured according to customer wishes in any sequence on a single assembly line. This means the flexible production capacities can be optimally utilized according to market demand.
