Audi previews the new TT

In less than two weeks, the new, third-generation Audi TT will make its world debut at the Geneva Motor Show.

So far, Audi has released just a sketch of the new TT, which will arrive later this year as a 2015 model. But that sketch reveals clear design cues that channel both the first-generation TT, introduced in 1998, and the more recent Allroad Shooting Brake Concept.

Horizontal lines dominate as well as connect the front and rear ends, counter-pointed on the sides by huge wheel arches, which are reminiscent of the original. So is the shallow roof-line, which now includes a mild hook in the C-pillar.

LED headlights will be offered as an option, as will Audi's Matrix Beam technology with incrementally-split light beam – in other markets. They're not legal in North America.

In back, TT versions feature two large, round exhaust tips in the diffuser, while the TTS features four pipes.

Inside, the central MMI monitor has been replaced by the Audi virtual cockpit, introduced at the CES International show in January.

Powertrain details have not yet been released.
