    Hans Stuck, Jr. dominated the 1989 IMSA-
GTO Championship in this all-wheel
drive racecar, the most powerful 
Audi ever, winning seven out of 13 races
contested.  Two races missed at the start of the season almost certainly cost
Stuck and teammate Hurley Haywood the Championship.  These lightweight racers
used a development of the 
Audi Sport quattro rally car's engine and featured
mainly aluminum and carbon fiber bodywork with a steel roof.
And also an Audi V8 DTM.

    Transformed from four-wheel drive luxury limo into successful racing car,
this model won the 1990 and 1991 Deutsche Tourenwagen-Meisterschaft (German

And a short wheelbase monster here is the 
Sport Quattro
