Unlike
other all-wheel-drive systems, we've built xDrive, BMW's intelligent
all-wheel-drive system with rear-wheel bias for surefooted grip on
slick or uneven roads, without sacrificing the feel of rear-wheel
drive. It smartly sends power to the wheel or wheels with the surest
footing--and it does so in milliseconds. That means under normal
conditions, drive forces are spread out with a rear-wheel bias. But the
moment the system senses excessive wheel slip, it subtly shifts torque
to meet the changing conditions, offering maximum available traction
and superior handling on all surfaces--despite the weather conditions.
Pioneering Origins
With
its ability to apportion torque instantly to the front and rear axles,
BMW's original xDrive became the benchmark in performance
all-wheel-drive systems. Continual improvements have ensured that it
maintained that position, even as competitors have developed
sophisticated systems of their own. Introduced
on the original X5, the first-generation xDrive was basically a passive
system that featured transferred power via a center differential, and
utilized the vehicle's braking system to stop wheel slippage, thereby
apportioning torque front to rear. The
second-generation all-wheel-drive system refined this design, adding
the ability to transfer torque directly via a central clutch that
operated independently of the brakes. By utilizing signals from the Dynamic Stability Control
the second-generation system could open or close the clutch to provide
instantaneous, continuously variable torque transfer front to rear.
This design is still used today.
Innovative Future
For the first time in a BMW, Dynamic Performance Control
gives the new BMW X6, BMW X6 M, and BMW X5 M unique new cornering
qualities as it seamlessly switches power between the left and right
rear wheels to stabilize the vehicle within milliseconds while
increasing traction and lateral acceleration.
That means you can enter bends more precisely and cross-accelerate faster with optimized grip when you accelerate out.
As
a logical progression of the BMW xDrive all-wheel-drive system, Dynamic
Performance Control can be matched to all drive concepts and engines.
Whereas BMW xDrive variably controls the power distribution between the
front and rear axles, Dynamic Performance Control intelligently
distributes power between the two rear wheels. This results in precise
handling whatever the driving conditions. Together with the all-wheel
BMW xDrive system, Dynamic Performance Control delivers enhanced
agility and dynamics on all surfaces.
Joy is always by your side. Joy is BMW Dynamic Performance Control.
