A preview of Audi's assault on the 1989 IMSA GTO Championship with the 90 quattro GTO.
I believe these tubular framed race cars only shared the roof of the B3 90! Not sure about that - those lights look familiar. They even have the circular boot lock!
Originally weighing just 900kg, I understand they had to take on an extra 300kg of weight ballast.
In race spec, power was about 720hp from an Audi 2.2L 20v inline 5 turbo with the quattro drivetrain providing the 'unfair advantage'. Boll**ks - the competitors were simply 'out-engineered'.
I've started looking for the original Amerian TV coverage of the races. Some full races are available on YouTube. Good racing!
Anyway, here's the preview
