Porsche Torque Vectoring (PTV)

This optional system for increasing dynamic performance and stability varies the distribution of torque to the rear wheels and includes a locking rear differential.

When the car is driven assertively into a corner, moderate brake pressure is applied to the inside rear wheel. Consequently, an additional rotational pulse (yaw movement) is induced around the vehicle’s vertical axis in the direction of the turn. This results in a direct and sporty steering action as the car enters the corner.

At low and medium vehicle speeds, PTV significantly increases agility and steering precision. At high speeds and when accelerating out of corners, the rear differential lock ensures greater driving stability and traction on road surfaces with varying grip, including wet and wintery conditions with cold weather tires.

The results are remarkable stability, optimum traction and excellent cornering dynamics at all speeds, coupled with precise steering and stable load transfer characteristics through every twist and turn of your journey.
