It’s not every day you come upon a car like the Audi 90 quattro IMSA GTO. This is a car that was short-lived, revolutionary, and awesome. Born following the Group B rally era, when Audi decided it wanted to see what the quattro system could do on pavement, it was the first all-wheel-drive car to compete in IMSA. In the late 1980s the IMSA GT series was at its peak, and the cars of the GT class lacked many restrictions. The 90 quattro fit in perfectly as it was hardly a GT car; it wasnothing [nic] less than a bespoke race car. One look at its ultra-wide body -- possibly the widest ever built -- will tell you that before your eyes is nothing more than a carbon-fiber silhouette shell. Underneath you will find a full-race tube chassis. Sitting forward of the front axle is a 720-horsepower motor driving all four wheels. It is a monster in all regards; lightning quick, with more grip than most can put to the pavement. During its single season in the IMSA GT Camel Pro series, the Audi 90 won seven of the 13 races. Audi went on to race in DTM, where quattro technology continued to dominate.
— Official description [1]

The 1989 Audi #4 Audi 90 quattro IMSA GTO is a GT racing car by Audi that is featured in the Nürburgring Booster Pack for Forza Motorsport 5, and in all subsequent Motorsport main titles.


The 90 quattro IMSA GTO was designed for the 1989 IMSA GT Championship series to compete in the GTO class. Similar to the Group B quattro S1, it is all-wheel drive and powered by a turbocharged inline-five with power increased to 711 hp (530 kW).

After the car completed its season run, Audi withdrew from the IMSA GT to focus on the Deutsche Tourenwagen Meisterschaft (German Touring Car Championship).[2]
