2012 All-New Porsche Carrera: Porsche Torque Vectoring (Part 7/12)



PORSCHE Euorpe: Official Press Release


The new Porsche 911 Carrera

More Dynamic Cornering with PTV and PTV Plus

The 911 Carrera provides even greater agility thanks to Porsche Torque Vectoring (PTV). The system exists in two versions: the PTV version with mechanical differential lock when twinned with manual transmission and in PDK vehicles as PTV Plus with electronically controlled, fully variable differential lock.

The system is featured as standard in the Carrera S and is available as an optional extra for the basic Carrera. In terms of driving dynamics and driving stability, the PTV/PTV Plus is the ideal complement to the Porsche Stability Management (PSM) system, fitted as standard.

In a nutshell, PTV/PTV Plus improves the vehicle’s steering behaviour and precision by means of precisely modulated braking interventions on the inside rear wheel when being driven in a highly dynamic style. PTV/PTV Plus offers significant benefits, especially when entering a corner. A braking force is selectively applied to the inside rear wheel as the steering manoeuvre is begun. This imparts a greater drive torque to the outside rear wheel compared with the inside wheel. This differential torque causes the vehicle to experience a yaw moment, which provides additional assistance to the steering wheel angle. The result is significantly greater agility with improved steering behaviour.
