This active all-wheel-drive system with variable torque distribution delivers engine power precisely to the road. By means of continuous monitoring of driving conditions, the system is able to respond to a variety of situations and adapt to your driving style. The electronically controlled clutch helps to ensure optimum distribution of force to all four wheels on road surfaces with irregular grip. The torque split between the front and rear axles is therefore fully variable – up to 100 % if necessary. In addition to traction, driving safety and outstanding steering performance, Porsche Traction Management (PTM) enables a high degree of driving stability, exceptional handling and excellent dynamics. In short, typical Porsche driving qualities.
