90 quattro IMSA GTO

Alright folks. This is not footage from Forza Horizon. This is as real as it can be. When this insane "RS6 GTO” concept car was presented to the world in November last year, many of us die-hard car fans, dropped their jaws to the ground. As a 40 year quattro celebration, it also paid homage to the legendary 90 quattro IMSA GTO race car.
