▷
The wheel angle is reduced in situations
that require minor or rapid corrections of
the direction of travel when driving at higher
speeds, e.g., swerving quickly or correcting
for crosswinds. In these cases, the variable
sports steering increases driving stability
when moving the steering wheel.
General information
BMW xDrive variably distributes the drive
forces to the front and rear axles as required
by the driving situation and road conditions.
Servotronic
Principle
Servotronic is a speed-dependent steering
support.
The system provides the steering force with
more support at low speeds than at higher
ones. This makes it easier to park, for instance,
and makes steering firmer when driving at
faster speeds.
Setting
The steering force adapts to the drive mode
to convey a firm, sporty feel or a comfortable
steering response.
Variable sport steering
The variable sports steering facilitates direct
and agile handling with little steering effort.
The variable sports steering responds inde-
pendently of the current speed, varying the
steering gear ratio in line with the steering an-
gle.
▷
In situations that require large movements
of the steering wheel, e.g., when maneu-
vering or turning, even minor movements of
the steering wheel will result in a greater
wheel steering angle. As a result, the varia-
ble sports steering increases steering com-
