xDrive
The innovative xDrive four-wheel drive is a system that controls and regulates the distrib-
ution of driving torque to the front and rear axles. The measured variables of DSC are
used by xDrive but are also influenced by modified handling performance.
The multi-disc clutch is the heart of the xDrive. By using the controlled multi-disc clutch,
it is possible to resolve the conflict between traction and handling performance.
This is achieved through the fact that torque distribution is not determined by a fixed gear
ratio in the xDrive as was the case in the previous systems. Instead, the distribution of dri-
ving torque is dependent on the locking torque of the controlled multi-disc clutch in the
transfer case and on the transferable torque to the front and rear axles.
DXC8+
The DXC8+ system adds features to the DSC8 system already in use in the E60 sedan
and combines features used in other DXC systems (E53/83). Due to the mechanical
composition of the xDrive system, the programming for DSC regulation has also been
changed.
Present DSC8 functions:
• ABS Anti-lock Braking System • ASC Automatic Stability Control
• ADB Automatic Differential Brake • DSC Dynamic Stability Control
• EBV Electronic Braking Force Distribution • DBC Dynamic Brake Control
• CBC Cornering Brake Control • MSR Engine Drag Torque Control
Present DXC functions:
• TCC Transfer Case Control
(control of multi-disc clutch in transfer case)
• ASC-X Automatic Stability Control X
(special function for all-wheel drive vehicles)
• ADB-X Automatic Differential Brake X
(special function for all-wheel drive vehicles)
• HDC Hill Decent Control
New DSC/DXC8+ functions
