PTM comprises of an active all-wheel drive system with an electronically variable, map-controlled multi-plate clutch, automatic brake differential (ABD) and anti-slip regulation (ASR).
The electronically controlled multi-plate clutch helps to ensure optimum distribution of force between the permanently driven rear axle and the front axle. The driving conditions are continuously monitored to enable the system to respond to a variety of situations. During cornering, the required level of engine torque is distributed to the front wheels to provide excellent lateral stability. The result: perfect distribution of drive torque at all times.
