The Audi 90 IMSA GTO was a legendary race car in the ’80s and ’90s. It was powered by Audi’s famous 2.2 liter turbocharged I5 engine that made the most incredible noise. It was driven by some of the all time greats, such as Walter Rohrl and Hans-Joachim Stuck. Just a legend for the Audi Sport brand (even if it wasn’t called Audi Sport then). Now, Audi Sport is paying tribute to that legendary car with the new Audi TT Clubsport Turbo Concept that’s just debuted at SEMA.
We’re actually surprised that Audi didn’t make a Clubsport concept out of the RS3 Sedan, considering the original 90 IMSA GTO was built off of a modified Audi 90 Sedan. Still, though, this is a crazy cool concept that pays homage to one of Audi’s greatest race cars.
On the outside, the Audi TT Clubsport Turbo Concept pays tribute to the 90 IMSA GTO with its massively flared wheel arches, huge fixed wing, hood vent and racing livery. It really does look like a modern interpretation of the all-time great piloted by Rohrl and Stuck. Under the hood is a modified variant of the same all-aluminum 2.5 liter turbocharged I5 engine in the standard TT RS. Except it’s been given an engine tune and electrically-powered compressor (EPC), which is basically just an electric turbocharger. The latter technique is also used on the Audi SQ7, allowing for low-end boost to come in at zero rpm, thus adding power while eliminating turbo lag.
This new engine is said to make a mighty 600 hp, 200 hp more than the standard TT RS. According to Audi, it can get from 0-60 mph in 3.6 seconds, although we expect it to be much quicker than that, considering the standard car is almost that fast and this Clubsport has way more power and far less weight.
The Audi TT Clubsport Turbo Concept is an awesome tribute to one of the all-time greatest Audi race cars and it goes about it tastefully. We would do bad things to drive it.
