Two years ago Audi unveiled an outstanding quattro concept car. There was even a rally model version of the concept car as a tribute to the Audi golden years in rallying with the unforgettable quattro cars of the Group B era.
Here is a nice artwork render of that quattro concept in a true Group B style. It looks very extreme and the aerodynamic are close to the legendary S1 quattro Pikes Peak car in the old style Audi Sport livery.
