The transmission of power to the four
drive wheels is provided permanently
through a transfer box. The distribution
of torque between the front and rear
axles is 38% to 62%.
Traditional differential locks at the front
and rear axles and in the transfer box
are not required. Their function is taken
over by automatic braking intervention
at all four wheels. These traction inter-
ventions are governed by Automatic
Differential Brake (ADB-X), a sub-func-
tion of DSC.
If a wheel tends to slip, it is braked
automatically by ADB-X until it once
again gains traction, and drive force
can be transmitted to that wheel. In
addition, the drive force is distributed
to the remaining wheels during this
530us133
system intervention. Engine output is
also reduced if necessary.
When the DSC is deactivated, the
ADB-X traction intervention is set for
the maximum drive force. However,
the engine intervention and the stability
controls are no longer available. For
this reason, DSC should only be deacti-
vated in the exceptional circumstances
described on page 95.
The BMW X5 is a vehicle for all types of
roads. The permanent four-wheel drive
provides a significant degree of vehicle
stability and tractive power under all
road conditions. It assists in critical
situations such as driving in extreme
winter conditions or on bad roads. Precision sensors monitor the wheel
speeds, the steering angle, lateral
acceleration, brake pressure and the
movement of the vehicle around its
vertical axis.
If differences in wheel speeds occur, the
system recognizes the danger of wheel-
spin and reduces the engine's drive
torque. If necessary, the system also
responds with additional braking inter-
vention at all four wheels.
In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor
signals. If deviations from this occur
(understeering or oversteering, for
instance), DSC can stabilize the vehicle
in fractions of a second by adapting
engine output and with the assistance of
braking intervention at individual
wheels. This way, as long as the skid
can still be managed under the laws of
physics, these kinds of dangerous skids
are prevented even before they can
start.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability. The braking
intervention may be accompanied by
certain sounds specific to the system.

200nRain sensor* Front axle
The rain sensor controls windshield
wiper operation, depending on how wet
the windshield is.
Infrared light is carried along the
surface of the windshield in an optical
conductor in such a manner that it is
reflected completely when the wind-
shield is dry. The quantity of reflected
light is measured.
If the window is covered with beads of
water, the amount of light that is
reflected is decreased since the
infrared light at the surface of the wind-
shield can then escape. The quantity of
reflected light is thus a means of
gauging the degree of wetness on the
windshield.
390de133
When the system is set to the "Intermit-
tent" wiper speed, the wipers react
immediately — if water is splashed onto
the windshield by vehicles traveling
ahead of you, for example. As a result,
the rain sensor provides a contribution
to driving safety and comfort.
The double-jointed suspension strut
axle is based on the same concept as
the one in the 7 Series, but was totally
re-developed because of the require-
ments for all-wheel drive. Parts
subjected to particularly high stress
levels for guiding the wheels are
designed as steel-forged parts to meet
the demands made by rougher roads.
The load-bearing front axle has large-
volume, hydraulically cushioned rubber
bearings that allow the axle to absorb
the reactive forces from the engine and
the braking forces from the front
wheels. An integrated rigid plate over
the load-bearing front axle provides
superb support against the lateral
forces introduced by the control arm
(wishbone), and also serves as an
effective protective barrier for the oil
pan and steering.

Overview
201nFront axle Integrated rear suspensionLevel 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.
530us131
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.
