The tremendous dynamic performance of the new Macan is thanks in part to the Porsche Traction Management (PTM) active all-wheel drive system. It comprises an electronic and map-controlled multi-plate clutch, the automatic brake differential (ABD) and anti-slip regulation (ASR). The electronically controlled multiplate clutch regulates the distribution of drive force between the rear axle and the front axle. Driving conditions are constantly monitored to enable a precise and lightning-quick response to a variety of situations.
Sensors continuously check, among other variables, the rotation speeds of all four wheels, the longitudinal and lateral acceleration of the vehicle, and the steering angle. If, for example, the rear wheels threaten to spin under acceleration, a greater proportion of drive force is distributed to the front by a more powerful engagement of the multiplate clutch. In addition, ASR reduces wheel slip. In corners, the drive force sent to the front wheels is regulated for optimum lateral stability.
In short, PTM transfers the incredible sportiness of the Macan to the road. Behind the wheel, you can feel what it's like to be driving a genuine sports car: traction, driving safety, outstanding steering behaviour, superior handling and, of course, the excellent dynamics typical of any Porsche.
