For 2013, the Audi TT is offered in both a coupe and roadster body style, both of which are built on Audi's improved aluminum space frame chassis, which consists of 69% aluminum, making it both lightweight and incredibly stiff.
Audi's signature quattro all-wheel-drive system is the only drivetrain available across the lineup. In addition, Audi's S-Tronic 6-speed dual-clutch automatic transmission is the only available gearbox on the TT and the TTS.
Both the TT and upscale TTS feature a healthy array of standard equipment, including an "Audi Concert" audio system, a driver information system and an automatic climate control system in the coupe.
Optional 'xenon plus' headlamps are available with cornering technology and both the TT and TTS are available with Audi's S-line competition package, consisting of special design touches to the bumpers, air inlets and rear diffuser, special interior detailing, a rear wing, unique 18-inch wheels and a 10-mm lower ride height. Optional magnetic ride shocks can be switched between "normal" and "sport" modes and a sport button modifies steering boost and exhaust sound. Optional napa leather gains a new thermal resistance treatment that cuts down on seat temperature significantly when left in the sun.
A high-performance model was introduced for 2012, called the RS. It features a 360-horsepower 5-cylinder engine mated to a 6-speed manual, the only transmission option. This combination is enough to scoot the TT to 60 mph in under 5 seconds. Audi's magnetic ride suspension, 19-inch alloy wheels, xenon HID headlamps and silk napa leather upholstery are all standard. The RS version of the TT represents the ultimate evolution of the car.
