Front axle

Integrated rear suspension Level control system

At the same time, particular attention
has been devoted to maintaining the
driving performance you have come
to expect from BMW.

This axle is based on the same multi-
link principle as that in 7 Series vehi-
cles. The axle's kinematics and elastic
kinematics are critical for wheel control
— a significant prerequisite for achieving
the objective of exceptional onroad
handling characteristics with this
vehicle concept.

In order to reduce unsprung mass, the
wheel carriers and the swing arm are
made of aluminum.

For an outstanding quality in acoustics
and vehicle oscillation characteristics,
the differential is isolated with double
elasticity through a chassis sub-frame
toward the vehicle body.

The level control system for the rear
axle maintains constant ground clear-
ance of your vehicle, even when
carrying a load.

For this purpose, the vehicle is
equipped with air springs instead of
steel springs at the rear axle. With the
help of two sensors, an electronic
control unit calculates the height of the
body at all times and, if it is required, it
allows air which is generated in a
compressor to flow into the air springs.

As a result of the pressure increase in
the air springs, the level control system
ensures not only constant ride height,
but also ride comfort which is indepen-
dent of the load the vehicle is carrying.
