At the Wortherseetour 2011, Audi will present their one-off A1 Clubsport Quattro, a special version of their new small city car, built to the limits of technology for dynamics. An impressive 2.5 liter, 503 horsepower, turbo engine sits inside the A1. Added width, air intakes and other design and performance details, make a racing machine out of the otherwise subtle city car. You can see it live in Austria from June 1st to June 4th.
