1989 Audi 90 IMSA GTO | Turbo flutter perfection | Festival of Speed 2025

One of the best-sounding racing cars of all time. Fact. The 2.2-litre 5 pot engine is a very special one. When those turbo flutters kick in, they raise the hairs on the arms of petrolheads worldwide. Famously driven by Hans-Joachim Stuck, Walter Röhrl and Hurley Haywood, the Audi 90 Quattro IMSA GTO right up there with the very coolest racing cars to have ever been built.

We were lucky enough to have this example at the 2025 Goodwood Festival of Speed presented by Mastercard and by the look on the crowd’s faces, you all enjoyed it as much as we did. For more content like this one follow us also on Facebook, Pinterest or Instagram!
