Porsche Torque Vectoring Plus (PTV and PTV Plus) 911 Targa 4S

Porsche Torque Vectoring Plus (PTV and PTV Plus)

Porsche Torque Vectoring Plus (PTV and PTV Plus)

PTV in conjunction with the manual gearbox, or PTV Plus with Porsche Doppelkupplung (PDK), are available as options for the 911 Targa 4 models and standard in the 911 Targa 4S models. Both systems actively enhance vehicle dynamics and stability. Operating in conjunction with a mechanical (PTV) or electronic (PTV Plus) rear differential lock, they work by braking the rear wheels as the situation demands.

As a function of steering angle and steering speed, accelerator pedal position, yaw rate and vehicle speed, PTV and PTV Plus are able to improve steering response and steering precision by specific braking of the right or left rear wheel.

To be more precise, this means that when the car is driven assertively into a corner, moderate brake pressure is applied to the inside rear wheel. Consequently, a greater amount of drive force is distributed to the outside rear wheel, inducing an additional rotational pulse (yaw movement) around the vehicle’s vertical axis. This results in a direct and sporty steering action as the car enters the corner.

At low and medium vehicle speeds, PTV and PTV Plus significantly increase agility and steering precision. At high speeds and when accelerating out of corners, the rear differential lock ensures greater driving stability. With PTV, the differential lock is regulated mechanically; with PTV Plus, it is regulated electronically and the torque distribution is infinitely variable. Whichever system is fitted, it interacts with Porsche Stability Management (PSM) to improve driving stability on a range of surface conditions, including the wet and snowy.

For the driver, this means remarkable stability, easier handling and outstanding traction as well as greater agility at every speed with precise steering and stable load transfer characteristics. What else? Unrivaled driving pleasure at every twist and turn.
