Audi has fitted the TT RS with a new turbo, 2.5-liter, 5-cylinder engine which pumps out a “neck breaking” 340-horspower and a max torque of 331.9 lbs. This TT also utilizes Audi's “Quattro” all-wheel drive system and a six-speed manual gearbox. Audi claims zero to 62 in under 5.0 seconds with a governed top speed of 155 mph. The TT RS also boasts a beefed up brake, suspension and electronic stability control system. The TT RS will be available in both Coupe and Roadster models. Sadly, Audi had opted not to offer the TT RS to the U.S. market for the time being.
