driving forces to the front and rear axles as de‐
manded by the driving situation and road surface.
Because of the needs-based use of the all-
wheel-drive system, Efficient4x4 yields a reduc‐
tion of the consumption.
M sport differential
The active M differential provides for continu‐
ously variable locking of the rear axle differential
depending on the driving situation. This prevents
spinning of a single rear wheel and thereby pro‐
vides optimal traction in any driving situation.
The driver is responsible adapting his or her driv‐
ing 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.
