Much like a mechanical limited-slip differential, torque vectoring subtly pulses the brake of the inside front wheel in a corner, directing more torque to the outside wheel, actually helping bend the car into a corner.
Both cars can be equipped with optional torque vectoring, a brake-based system built to augment the mechanically locking rear differential and help put power to the ground.
The computer-control system can then apply the brake on the wheel concerned, and even adjust the amount of engine torque sent to that wheel, so that skidding is prevented.
