Porsche Panamera 4 - Porsche Traction Management (PTM)

Porsche Traction Management (PTM)

Porsche Traction Management (PTM) comprises an active all-wheel drive with electronic and map-controlled multi-plate clutch, with automatic brake differential (ABD) and anti-slip regulation (ASR).

The electronically controlled multi-plate clutch regulates the distribution of drive force between the permanently driven rear axle and the front axle. The driving conditions are continuously monitored.

The electronics can then respond to a variety of situations. Sensors check, among other variables, the rotation speeds of all four wheels, longitudinal and lateral acceleration of the vehicle, and the steering angle. If, for example, the rear wheels spin under acceleration, a greater proportion of drive force is redirected to the front by a more powerful engagement of the multi-plate clutch. In addition, ASR reduces wheel slip. In corners, the drive force sent to the front wheels is regulated for optimum lateral stability.

In this way, in conjunction with Porsche Stability Management (PSM), PTM ensures optimum force delivery in every driving situation and excellent acceleration power: whether on long straights, through tight corners, or on road surfaces with varying grip.

Standard in the Panamera 4, Panamera 4S, Panamera GTS and Panamera Turbo.
