What looks like an unassuming Audi TT is actually a prototype for a new RS version of the popular sports car. Caught undergoing testing in Germany, the TT RS is likely to pack a twin-turbo charged version of the two-liter TSFI four-cylinder instead of the larger 3.2-liter V-6 engine.
Power output of the new car will surpass that of the current V-6 model. Expect at least 300 horsepower, which might even allow the car to hit 0-60 mph in less than five seconds. Audi will still provide a conventional six-speed manual transmission but we suspect most buyers will opt for the magnificent S-tronic double clutch system.
Changes for the TT in RS guise will include new aluminum components to help shed weight as well as the mandatory body kit and alloys. Sales of the TT RS in the U.S. won't start until the 2012 model year, but we should see the car before then.
