Porsche Traction Management (PTM)

Porsche Traction Management (PTM)

General

All Cayenne models are equipped with Porsche Traction Management (PTM) for superior driving stability, outstanding traction and handling typical of a sports car. The new development of the PTM focused on optimizing the on-road performance of all Cayenne models as well as maintaining the required off-road characteristics inherent to the design. This resulted in the production of a PTM system that was adapted specially to the new Cayenne models. The low weight of the extremely compact all-wheel systems makes an important contribution to reducing the fuel consumption of the vehicle. Moreover, the system is equipped with an Automatic Brake Differential (ABD) for improving traction, Anti-Slip Regulation (ASR) for enhancing vehicle stability and Porsche Hill Control (PHC) for the controlled descent of steep inclines.
