All Panamera Sport Turismo models are equipped with Porsche Traction Management (PTM). This active all-wheel drive with electronic and map-controlled multi-plate clutch ensures the optimum distribution of drive force whatever the driving situation – for excellent acceleration power on long straights, through tight corners and on road surfaces with varying grip.
The multi-plate clutch regulates the distribution of drive force between the rear axle and the front axle. Driving conditions are constantly monitored, enabling the system to respond to a variety of situations. Sensors check, among other variables, the rotation speeds of all four wheels, the longitudinal and lateral acceleration of the vehicle, and the steering angle. If the rear wheels threaten to spin under acceleration, a greater proportion of drive force is distributed to the front by a more powerful engagement of the multi-plate clutch.
