Porsche Traction Management (PTM) 911 Turbo S Cabriolet

Porsche 911 Turbo S Cabriolet - Porsche Traction Management (PTM)

Porsche Traction Management (PTM)

Enhanced Porsche Traction Management (PTM) with water-cooled front-axle gearbox is standard in all of the new 911 Turbo models. It is an active all-wheel-drive system with an electronically variable map-controlled multi-plate clutch, automatic brake differential (ABD) and anti-slip regulation (ASR).

And it delivers the high power of the new 911 Turbo models even more effectively and efficiently to the road. This is thanks to the new water cooling system for the front-axle transmission. Water conducts heat better than air. So the cooling jackets placed on the transmission have several advantages: when you set off, the water ensures that it warms up more quickly – and reaches its optimum temperature sooner. And during the drive itself, the heat produced is dissipated more easily. So more torque – i.e. more drive force – can be transmitted through the gearbox to the front axle.

Drive power is distributed between the permanently driven rear axle and the front axle by means of the electronically variable multi-plate clutch.

The status of the vehicle is continuously monitored so that it is possible to respond to different driving situations. Sensors are used to collect a range of data, including the rotational speed of all four wheels, the lateral and longitudinal acceleration of the car and the current steering angle.

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, ASR prevents wheel spin by adapting the engine’s power output. 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, whether on long straights, through tight corners, or on surfaces with different friction coefficients.
