Dynamic Stability Control (DSC) – BMW 325xi
The concept
DSC maintains vehicle stability, even in
critical driving situations.
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, as far as is
possible within the laws of physics,
helps keeping the vehicle on a steady
course by reducing the engine speed
and brake applications to the individual
wheels.

the engine. DSC includes the functions

The Automatic Differential Brake
(ADB-X) enhances traction in critical
situations (such as those encountered
on snow-covered roads) by using
selective braking intervention to replace
the limited-slip functions executed by
the differential and transfer case in
conventional drivetrains.

operational, however, without DSC. In
the event of a malfunction, please
