Standard in all 911 Turbo models: PTV Plus. The system actively enhances vehicle dynamics and stability and operates, in conjunction with an electronic rear differential lock, by varying the distribution of torque applied to the rear wheels.
As a function of steering angle and steering speed, accelerator pedal position, yaw rate and vehicle speed, PTV Plus is 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 Plus significantly increases agility and steering precision. At higher speeds and when accelerating out of corners, the rear differential lock, with infinitely variable torque distribution, helps to ensure greater driving stability.
The system thus interacts with Porsche Stability Management (PSM) to improve driving stability on a range of surface conditions, including the wet and snow.
But what does that mean for the driver? Remarkable stability, easier handling and outstanding traction. As well as greater agility with precise steering and stable load transfer characteristics. What else? Unrivalled driving pleasure at every twist and turn.
