Other torque vectoring all-wheel drive systems
Seen on: Saab Cross-Wheel Drive (XWD), Nissan Juke Torque Vectoring AWD, Audi Quattro with Sport Differential
How they work: A vehicle with torque vectoring can start as an on-demand or full-time all-wheel-drive system. What sets these cars apart is the magic that happens on the rear axle. Like any other AWD system with a rear differential, whatever power is sent to the rear axle is then split between the rear wheels. Unlike a standard limited slip differential, which reacts to increase traction, a torque vectoring system's active rear differential proactively sends power to the wheel where it can best be used--usually the outside rear wheel in a turn. Saab's XWD system can send as much as 85 percent of available engine torque to a single rear wheel if its ECU deems necessary.
The result is what is known as a yaw moment, the scientific term for when the car swings its tail and rotates through a turn. Nissan has a video demonstration of the Juke's Torque Vectoring system in action.
Advantages: Dramatically improved handling, even faster cornering than standard RWD and RWD-weighted AWD systems
