PTV Plus is specially designed for the new 911 GT2 RS and operates in conjunction with an electronically controlled, fully-variable rear differential lock.
To actively control the differential lock, a number of driving parameters are considered. The result: increased traction, especially at the limits of dynamic driving performance, better transverse dynamics and significantly improved driving stability during load changes, in bends and when switching lanes. The system also selectively applies brake pressure to the right and or left rear wheel. So brake pressure is applied to the inside rear wheel as soon as the steering kicks in. A greater amount of drive force is distributed to the outside rear wheel, thereby pulling the car into the bend, as it were. Steering is therefore improved and agility increased.
