2014 Audi TT | spy shots

Audi's third-generation TT is waiting in the wings for a 2014 reveal, but spy pics show there may not be too many surprises. The camouflaged prototype's body largely echoes the current TT, although front styling has been updated with a new larger grille flanked by sharper headlight clusters and the rear scores new LED lights, revised bumper and dual-tip exhaust.

The car will be underpinned by the new lightweight scalable MQB platform from parent Volkswagen Group, which will be used for most of the VW Group vehicles with transversely-mounted engines. 

There's no confirmation of which units will appear under the TT model's bonnets, but the front-wheel drive base model is likely to be powered by a turbocharged 2.0-litre four-cylinder developing at least 160kW.

Quattro all-wheel drive and cabriolet versions will slot in higher up the scale, and the sporty 221kW/380Nm turbo 2.0-litre from the Audi S3 and the 265kW/465Nm 2.5-litre from the current TT RS are on the cards, with the latter tipped to be getting a power boost of 20kW.
