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.
