The Audi Quattro was the first rally car to utilize a four-wheel-drive system in accordance with updated regulations for the 1980 WRC season. The Quattro immediately began to dominate not only WRC but also in a variety of other racing series worldwide. The use of proprietary Torsen differential technologies gave the Quattro such a significant advantage that it was eventually banned, which only served to make it more desireable.
This car is actually a WRC replica as the real thing is quickly becoming too valuable to drive.
