Sometimes it seems as though Audi is determined to match Mercedes model for model. This so-called 4-door coupe, named A7, will go up against the Mercedes-Benz CLS in 2008, while the next generation Audi A8 will be 4" longer and offer both a V-12 diesel and a new V-10 gas engine, making it a strong competitor for Mercedes newest S-Class Luxury Sedan. The A7 coupe is based on the A6, according to an article in Autoweek, and includes "a chopped roofline, an aggressive nose design with a radical headlight treatment, and rear door handles hidden within the C-pillar supports."
