Audi 90 Quattro IMSA GTO (1989)
Over in the US, car racing is a way of life and the Trans-Am series is the pinicle of every drivers aspirations.
It had mostly been dominated by American muscle V8’s but in 1988, the Audi 200 be ame the unlikely championship contender.
Audi won the championship, winning 8 out of 13 races. To everyone’s amasement, Audi coaxed 510hp out of their little 2.1lt 5-cylinder engine and coupled with their incredible Quattro system, they dominated the field
So much so, in fact, that all-wheel drive was banned at the end of the season.
Audi switched to the IMSA series the following year , and created an all-new tubular steel spaceframe, clothed in a body that resembled the Audi 90 Quattro.
Audi effectively shoe-horned the mechanical bits of the highly successful Group B world rally car into a silhouette track car.
The 20-valve, 2.2-litre five-pot had a massive KKK turbo bolted onto it, and made 720hp. One of it’s more memorable features was the exhaust that exited, in gigantically unsubtle fashion, through what would have been the passenger door.
Despite its strong showing coming runner-up in it’s maiden season, Audi’s German bosses decided to focus the company’s motorsport’s efforts on the domestic DTM series, pulling the plug on the 90 quattro’s US exploits.
