Porsche Traction Management (PTM) 911 Turbo Models

Provided as standard, Porsche Traction Management (PTM) is an active all-wheel drive system with an electronically variable map-controlled multi-plate clutch. It distributes drive power between the permanently driven rear axle and the front axle.

If, for example, the rear wheels begin to lose traction under acceleration, a greater proportion of the drive power is automatically transmitted to the front axle by a more positive engagement of the multi-plate clutch. In addition, antislip regulation (ASR) prevents wheel spin. During cornering, the optimal level of drive power is distributed to the front wheels to ensure excellent lateral stability. In conjunction with Porsche Stability Management (PSM), PTM helps to ensure the perfect distribution of drive power for optimum traction in most road scenarios.
