This optional system for increasing dynamic performance and stability varies the distribution of torque to the rear wheels and includes a mechanically locking rear differential.
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 significantly increases agility and steering precision. At high speeds and when accelerating out of corners, the rear differential lock ensures greater driving stability on a range of surface conditions, including the wet and snow.
The results are remarkable stability, easier handling and outstanding traction as well as greater agility at every speed with precise steering and stable load transfer characteristics. What else? As ever, lots of excitement at every twist and turn.
