BMW xDrive
Principle
BMW xDrive is the all-wheel-drive system of
the vehicle. BMW xDrive and other suspension
control systems, e.g., Dynamic Stability Con-
trol, work together to further optimize traction
and driving dynamics.
General information
BMW xDrive variably distributes driving forces
to the front and rear axles as required by the
driving situation and road conditions.
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 all-
wheel-drive system, Efficient4x4 yields a re-
duction in consumption.
M sport differential
The M Sport differential provides for continu-
ously variable locking of the rear axle differen-
tial, depending on the driving situation. It pre-
vents a single rear wheel from spinning and
depending on the situation, increases the drive
power of the wheel with greater road grip. This
significantly improves the traction and driving
dynamics of the vehicle.
The driver is responsible adapting his or her
driving style to the situation.

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.
Driving mode
Integral Active Steering
COMFORT
Comfortable, for optimal
travel comfort.
ECO PRO
SPORT
Dynamic, for greater agil-
ity.
The different settings are assigned to the dif-
ferent driving modes of the Driving Dynamics
Control.
