The sleek three-door has already been revealed in concept form at the Frankfurt Motor Show in September. But these spy shots give the clearest view yet of the production model.Snapped with a camera phone as engineers took a break from their test route, the images show all the details of the stylish machine. It will break new ground for Renault by offering a cheaper alternative to the likes of the Audi A5 and forthcoming Volkswagen Passat CoupĂ©. The sporty model is based on the same platform as the five-door, and gets four-wheel steering, plus a choice of punchy petrol and diesel engines. A flagship version will be powered by a new V6 diesel, producing up to 260bhp. But this model is unlikely to be offered from launch. When the CoupĂ© arrives at the end of the year, prices should range from about £23,000 to £30,000-plus.
