optimise traction under such conditions a drive wheel spinning when accelerat-
ing out of a tight bend is slowed down precisely as required by the brakes,
allowing the opposite wheel on the same axle to maintain the drive power and
traction required.
Special option for greater dynamics and additional comfort:
Adaptive Drive.
As an option the BMW 5 Series Gran Turismo is available with Adaptive Drive
combining the electronically controlled dampers and the car’s active anti-roll
stability system. The innovative dampers used in this case adjust both to road
conditions and the driver’s style of motoring in order to prevent any undesired
movement of the vehicle caused by bumps on the road or a high level of
lateral acceleration.
The driver is able to adjust the damper control map via Dynamic Drive Control,
choosing from a comfortable, a normal and a sporting set-up. This is also why
Dynamic Drive Control interacting with Adaptive Drive also comes with the
COMFORT mode.
BMW is the world’s first car maker to use a damping system with infinite and
independent adjustment of the inbound and rebound strokes, with a unique
combination of a firm suspension set-up and, at the same time, a comfortable
response to bumps and unsmooth surfaces on the road.
With these dampers, the up-and-down movement of each wheel is determined
by sensors and reported to the central control unit, taking these data and
signals on the car’s ride height to determine any movement of the body. Making
allowance also for road speed and the damper setting chosen by the driver, the
system then calculates the damper force required on each wheel in order to set
off body movements.
The data used for this purpose is fed to the dampers in intervals of just 2.5 milli-
seconds, with actual and target settings being established individually on each
wheel by controlling the inbound and rebound stroke valves in the dampers.
Active anti-roll stabilisation likewise included in the optional Adaptive Drive
function reduces body sway in fast bends and under a sudden change of direc-
tion. Taking current driving conditions into account, sensors determine the side
angle of the body and swivel motors in the anti-roll bars front and rear quickly
and precisely counteract the forces recorded, significantly improving the car’s
