Audi has confirmed that the all-new TT will be available from launch with a choice of three four-cylinder direct injection turbo engines with power outputs ranging from 184 to 310PS. There will be two versions: a TT and a TTS -- with the latter delivering a provisional 0-62 time of 4.7 seconds when fitted with the optional 6-speed S tronic transmission. Under the skin the revised quattro all-wheel drive system can now temporarily deactivate to improve efficiency, while in the cabin, the driver is greeted by an all-digital 'Audi virtual cockpit'.
