1986: The Torsen differential in the Audi quattro - With the debut of the Audi 80 quattro in fall 1986, Audi introduced a new center differential a component that was still strictly mechanical, but highly efficient. The name Torsen was a contraction of the English words torque and sensing. The Torsen differential had already proved itself in the world of technology as a high-tech rear axle differential; Audi developed it further for use as a center differential.
