This electronic active damping system offers continuous adjustment of the damping force on each wheel based on the current driving situation and your driving style.
At the press of a button, you can select between two different modes. ‘Normal’ mode is designed for sporty driving on public roads and on wet racetracks. ‘Sport’ mode is specially tuned for maximum lateral acceleration and offers the best possible traction on the track.
PSM automatically maintains stability even at the limits of dynamic driving performance. In addition to the anti-lock braking system, it includes Electronic Stability Control (ESC) and Traction Control (TC).
Sensors continuously monitor the direction, speed, yaw velocity and lateral acceleration of the car. Using this information, PSM is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels to restore stability.
What’s special about PSM in the new 911 GT3? The systems intervene with exceptional sensitivity and precision and can be completely deactivated in two stages for deliberately sporty handling.
PTV Plus has been specially adapted to the new 911 GT3. In conjunction with PDK, fitted as standard, the system operates with an electronically regulated and fully variable rear differential lock.
Numerous driving parameter inputs are the basis for the system’s active control of the differential lock. The results are greater traction, particularly at the limits of dynamic performance, increased lateral dynamics and a significant improvement in driving stability under the effects of load changes in corners and when the car changes lane.
PTV – in conjunction with the optional GT sports manual transmission – operates with a mechanically regulated rear differential lock.
On surfaces with less grip, such as in the wet, each system strategically brakes the right or left rear wheel. This means that, whenever the car enters a corner, brake pressure is applied to the inside rear wheel. Consequently, a greater amount of drive force is distributed to the outside rear wheel, improving steering response and increasing agility.
The result: unrivalled pleasure at every twist and turn. It’s just as well there happens to be so many waiting on the racetrack.
