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.
