CONTROLS
xDrive and other suspension control systems
such as Dynamic Stability Control further opti-
mizes traction and driving dynamics.
General information
BMW xDrive variably distributes the drive
forces to the front and rear axles as required
by the driving situation and road conditions.
Integral Active Steering
Principle
The Integral Active Steering increases the ma-
neuverability of the vehicle and makes a more
direct steering response possible. Driving sta-
bility is also increased at high speeds.
General information
Integral Active Steering combines the variable
steering gear ratio of the front axle with active
rear-wheel steering.
The rear axle steering acts to increase maneu-
verability at low speeds by turning the rear
wheels slightly in the opposite direction to the
front wheels.
At higher speeds, the rear wheels are turned
in the same direction as the front wheels. For
instance, this results in a harmonious lane
change.
In critical driving situations, integral active
steering can stabilize the vehicle by automat-
ically steering the rear wheels, for example e.g.
when oversteering.
Setting
The system offers several different settings.
With the driving modes of the My Modes, the
system can be set to comfortable or dynamic.
