BMW 3: xDrive

Concept

xDrive is the all-wheel-drive system of the vehicle.

The interaction of xDrive and other suspension control systems, such as DSC Dynamic Stability Control, further optimizes traction and driving dynamics. xDrive variably distributes the driving forces to the front and rear axles as demanded by the driving situation and road surface.

The Driving Dynamics Control is used to change the all-wheel distribution from traction oriented to sport oriented.

Because of the needs-based use of the allwheel- drive system, Efficient4x4 yields a reduction in consumption.

M sport differential

The active M differential provides for continuously variable locking of the rear axle differential depending on the driving situation. This prevents spinning of a single rear wheel and thereby provides optimal traction in any driving situation.

The driver is responsible adapting his or her driving style to the situation.

Variable sport steering

The variable sport steering facilitates a direct and agile driving style with little steering effort. The variable sports steering works independently of the current speed, varying the steering ratio in line with the steering angle.

     Manual Speed Limiter

    Concept The system can be used to set a speed limit, for instance to prevent the vehicle from exceeding speed limits. General information The system can limit the speed, starting at a value of 20 mph/

     Cruise control

    Concept Using this system, a desired speed can be adjusted using the buttons on the steering wheel. The system maintains the desired speed. The system accelerates and brakes automatically as needed.

     Displays and operation

    The function does not have any separate display or operating elements. The function is only available in the HYBRID ECO PRO driving mode. The function cannot be deactivated. Recuperation is displayed as usual in the instrument cluster below the drive-ready state indicator (CHARGE area).

     Interior air quality, Automatic climate control

    Interior air quality The air quality in the vehicle is improved by the following components: Emission tested passenger compartment. Microfilter. Air conditioning system to control the temperature, air flow and recirculated-air mode. Depending on the equipment specification: Microfilter/activ
