Audi quattro
When the Audi quattro first appeared at the Geneva Motor Show in 1980, it introduced a means of transmitting power that was entirely new in the passenger car sector - an all-wheel drive system that was lightweight, compact, efficient and low-tension. This made the quattro concept particularly suited to fast, sporty cars and high-volume production right from the outset.
The 147 kW (200 PS) original quattro remained part of the product range as a standard model until 1991 and underwent several technical revisions. In 1984, Audi added the exclusive "short" Sport quattro with an output of 225 kW (306 PS). With the introduction of the Audi 80 quattro in 1986, the center differential that could be locked only manually until then was replaced with the first self-locking center differential. It provided purely mechanical distribution of the drive torque between the front and rear axles at a 50:50 ratio. Under load, it transferred up to 75 percent to the axle with better traction as needed.
