xDrive
Principle
xDrive is the all-wheel drive system of the ve-
hicle. Concerted action by the xDrive and and
other suspension control systems, for exam-
ple, Dynamic Stability Control, further optimi-
ses traction and driving dynamics.
General
xDrive distributes the driving power variably to
the front and rear axles according to the driv-
ing situation and road condition.
Efficient4x4 reduces consumption by deploy-
ing all-wheel drive as required.
M Sport differential
The active M differential steplessly locks the
rear axle differential according to the driv-
ing situation. This prevents an individual rear
wheel from spinning, thus providing optimum
traction in all driving situations.
It is the driver's responsibility to adopt a driving
style that is appropriate to the situation.
Variable sport steering
The variable sport steering facilitates direct
and agile drivability with less steering effort.

Irrespective of the current speed, the variable
sport steering reacts to the steering angle with
varying steering ratios.
