Quattro was made famous by Audi over ten years ago. After using it to dominate motorsports, they incorporated versions of it into its road cars, culminating with the torsen-based system found on the Audi A4. The system has changed gradually over the years, moving from a 50:50 torque split to a rear-biased 40:60. Torque vectoring was added in with the debut of the S4 sedan last year. Now at the Geneva Auto Salon, Audi debuted it’s new Quattro system that uses a new center differential. This is significant because Audi stayed with the Torsen center diff from 1996 all the way until this year. Whether this new diff gets put into the regular series of cars or remains an RS-exclusive remains to be seen.
The new center diff is explained in the video below, and also goes over the torque vectoring concept. The RS5 and S4 both come with torque vectoring, and is also seen on the new 2010 Porsche Carrera Turbo.
