The new Audi TT Roadster has been added to the TT Coupe line-up for the 2001 model year. The TT Roadster is available in two drive configurations: either a 180-hp engine with front wheel drive, or a 225-hp engine with the Quattro drivetrain. The TT Roadster Quattro is equipped with a six-speed manual transmission and ventilated disc brakes. The TT Roadsters folding soft top includes a heated glass rear window, and an electronic interior monitoring system that prevents intrusion when the roof is lowered. The Roadsters aluminum rollover bars are an integral component of the body structure, improving rigidity and occupant safety. The TT Roadster and the 225-hp TT Coupe are scheduled for release in May.
