Audi's All-Conquering American Quattro Mooned The Rest Of The Racetrack

This is the story of why one of the most dominant race cars of the modern era, the IMSA GTO Audi 90 Quattro, had a little doll that mooned other racers.

Back in 1989, these Audis were so dominant that one non-Audi competitor made up a "no passing" sticker with Audi driver Hans-Joachim Stuck's face on it. Hans-Joachim Stuck had the best response ever: moon 'em when you pass. Stuck's GTO-class Audi 90 quattro featured a doll in the rear window who'd drop his trousers whenever Stuck flew past.

It's a good thing we light-hearted Americans allowed such frivolities. And by frivolities, I mean butts.

The full video on Audi's American efforts in 1988 and 1989 is a delightful blast from the past that's worth watching in its entirety, too. Audi's all-wheel-drive 200 Quattro so thoroughly dominated Trans-Am in 1988 that Trans-Am banned both all-wheel-drive and non-American engines the following year.

So, Audi moved to IMSA's GTO class for 1989 with a tube-frame Audi 90 Quattro that was just as bonkers. Watch the full thing here.
