The Mercedes CLS-rivalling Audi A7 Coupé, set to be one of the most eagerly anticipated models of 2009, has finally broken cover. And with its curving roof line and sleek silhouette, it promises to be one of the most dramatically styled models in its class.

Mimicking the basic proportions of its Mercedes rival, with the cockpit space stretching the length of the car and tailing off towards the rear, but with a much more imposing and aggressive look, the Audi A7 will be heavily influenced by the Audi A5 coupé, featuring flared arches and a low ride height.

Since it will be based on the same platform as the new Audi A8, it also gets a rigid aluminium spaceframe body.

Air-suspension will be fitted as standard, and is likely to be combined with Audi’s Drive Select adaptive dampers, offering drivers a variety of chassis settings.

A wide range of models is promised, with prices starting at around £45,000.

Under the bonnet, six engines will appear at launch, including a trio of V6 diesels. One of these is an all-new 3.0-litre twin-turbocharged unit, while the V8 and supercharged V6 petrol power plants will also be available.

An Audi RS7, featuring a 600bhp-plus version of the Audi RS6’s twin-turbo V10 engine, may also follow.
