Four-Wheel Drive Coupling

Four-Wheel Drive Coupling

The four-wheel drive coupling is an electronically controlled multi-plate clutch. On the 4MOTION permanent four-wheel drive system, it enables the propulsive power to be distributed variably between the front and rear wheels. Its continuous adjustment is performed by a control unit that takes slip, handling conditions and drive torque into account.

The four-wheel drive coupling’s action is permanently integrated into the electronic stability control (ESC) and therefore improves the vehicle’s safety.
