When it premieres in Geneva next month, the Audi TT RS will arrive in both coupe and convertible bodystyles. Both are powered by a 340-horsepower, 331 lb-ft, 2.5-liter turbo five cylinder. The driver rows a six-speed stick, and quattro channels power to all the wheels. 0-62 mph takes under 5 seconds. As the teaser shots hinted, look for more aggressive front and rear fascias, LED driving lamps, and a fixed rear spoiler. As with other RS cars, the brakes and suspension are also beefed up.
