Porsche Torque Vectoring (PTV) 718 Cayman Models

PTV is an optional system for enhancing driving dynamics and stability. Operating in conjunction with a mechanical rear differential lock, it works by varying the amount of torque transmitted to the rear wheels. When the car is driven assertively into a corner, moderate brake pressure is applied to the inside rear wheel.

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 from the turn-in point.

At low and medium vehicle speeds, PTV significantly increases agility and steering precision. At high speeds and under acceleration out of corners, the mechanically controlled rear differential lock also acts to provide greater driving stability and traction.

For the driver, this means strong resistance to destabilising side forces, outstanding traction and great agility at every speed – with precise turn-in and well-balanced load transfer characteristics. What else? Tremendous fun in the corners.
