Audi TT sports coupe teased

We've got only a couple of weeks to wait until Audi pulls the silk of its third-generation TT coupe at the Geneva motor show on March 4, but the German luxury brand has released some drawings that give us a reasonable idea of what to expect.

As the Carsguide spy photographers have already revealed with shots of the car in testing, the TT has retained the signature lines penned by Peter Schreyer (before he left Audi to head up Kia and Hyundai design) but also takes some cues from the Allroad Shooting Brake concept unveiled at Detroit motor show last month.

A broad, flattened single-frame grille accentuates the low-slung horizontal styling of the face, set off with wide-set headlight clusters -- which will feature the options of LED lamps and Audi's new beam-splitting Matrix technology in some markets.

The cabin treatment has already been revealed last month at the Las Vegas Consumer Electronics show, with the highlight being the new iPad-sized 12.3-inch display screen behind the steering wheel in place of the main instrument cluster.

The new TT rolls on parent Volkswagen Group's flexible MQB platform, which will eventually underpin a whole fleet of different models across VW, Audi and Skoda, and with extensive use of aluminium in the body should help the car trim some weight that will help both economy and handling.

The engine line-up is expected to kick off with a 132kW 1.8-litre TFSI engine driving only the front wheels in the entry level model, while all-wheel drive models will carry turbocharged 2.0-litre TFSI engines delivering 162kW and then  221kW in TT S spec. We're also likely later in the year to see a TT RS for the third generation, tipped to be in line for a 300kW iteration of the 2.5-litre five-cylinder.

Transmissions choices are said to be a standard six-speed manual or optional seven-speed dual-clutch. After its show debut, the new TT will go on sale in overseas markets towards the end of the year, and arrive here some time in 2015.
