The 2008 Audi TT roadster mimics the hardtop version's style and powertrain options - either a 200-hp 2.0-liter turbo four powering the front wheels or a 250-hp 3.2-liter V-6 with Quattro all-wheel-drive. Both engines come with either a six-speed manual transmission or a six-speed S-tronic (Audi's new name for DSG) dual-clutch gearbox with steering-wheel-mounted paddle shifters. Audi claims the 0-to-60-mph times with the S-tronic are 6.5 seconds for the 2.0-liter and 5.9 seconds for the 3.2-liter.
