Porsche Torque Vectoring Plus is fitted as standard and has been specially adapted to the new 911 GT3. It operates in conjunction with an electronically regulated and fully variable rear differential lock. Numerous driving parameter inputs are the basis for the system’s active control outputs. The results are perceptible, particularly at the limits of dynamic performance: greater traction, increased lateral dynamics and a significant improvement in driving stability under the effects of load changes in corners and when the car changes lane. On surfaces with less grip, such as in the wet, the 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. This improves steering behaviour and increases agility.
