Photos: BMW 135i Coupe

BMW showed off its entry-level 135i sport coupe at the 2007 Frankfurt auto show. But with BMW, "entry-level" means one of the most exciting small cars available. Although the 135i is BMW's smallest four-seater, the company packs its incredible twin-turbo, 3-liter, straight six-cylinder engine under the hood. And best of all, BMW will import the 135i to the U.S.
