BMW 7 Series: DTC Dynamic Traction Control

Concept

DTC is a version of the DSC Dynamic Stability Control where forward momentum is optimized.

The system ensures maximum headway on special road conditions or loose road surfaces, for instance unplowed snowy roads, but with somewhat limited driving stability.

General information

When DTC is activated, the vehicle has maximum traction. Driving stability is limited during acceleration and when driving in curves.

You may find it useful to briefly activate DTC in the following situations:

  • When driving in slush or on uncleared, snowcovered roads.
  • When driving off from deep snow or loose ground.
  • When driving with snow chains.

Automatic program change

In certain situations, the DSC is activated automatically:

  • If Active Cruise Control with Stop&Go function ACC is activated.
  • On a braking intervention by the Intelligent Safety systems.
  • The vehicle has a flat tire.

xDrive

Concept

xDrive is the all-wheel-drive system of the vehicle.

The interaction of xDrive and other suspension control systems, such as DSC Dynamic Stability Control, further optimizes traction and driving dynamics. xDrive variably distributes the driving forces to the front and rear axles as demanded by the driving situation and road surface.

The Driving Dynamics Control is used to change the all-wheel distribution from traction oriented to sport oriented.

Because of the needs-based use of the allwheel- drive system, Efficient4x4 yields a reduction in consumption.
