The Hottest Luxury Cars of 2013

BMW M6 Gran Coupe (shown above is the two-door M6 Coupe) Why it is hot: It has the same exact engine—a 4.4-litre turbo V8--as the M5 and the M6. With 560 horsepower. And a handsomely chiseled front set off with LED lights. BMW will unveil it at the Detroit Auto Show in January.
