Porsche Traction Management (PTM) Cayenne Diesel

Porsche Traction Management (PTM)

The Cayenne Diesel and Cayenne S Hybrid feature a permanent all-wheel drive system with self-locking center differential. This provides a standard torque split of 60 percent to the rear and 40 percent to the front. If one of the wheels is about to lose grip, the self-locking center differential transmits the torque to the axle offering the highest level of traction. The ASR and ABD systems work in the same way as in the PTM on the Cayenne, Cayenne S and Cayenne Turbo.

On the Cayenne Diesel and Cayenne S Hybrid, PTM also enables variable distribution of engine torque to the rear wheels, thereby enhancing steering precision and driving dynamics. Specifically, this means that when entering a corner at high speed, moderate brake pressure is applied to the inside rear wheel. This supports the steering motion of the car, thereby improving its cornering dynamics.

Standard on the Cayenne Diesel and Cayenne S Hybrid.
