Is it a coupe? A sedan? A sportback? We're not really sure, because Audi uses at least two of the three to describe the 2014 Audi RS 7 ($TBA). This new sporty model features five doors, a low-slung body, quattro all-wheel drive, 20-inch wheels, and a suitably elegant interior. The real star, though, is the 4.0 TFSI engine cranking out 560hp, a number that — when combined with the standard eight-speed tiptronic transmission — enables a 0-62 time of just 3.9 seconds and a top speed of nearly 190 mph, all while offering an average fuel economy of 24 mpg.
