The Audi Crosslane Coupe Concept is all about the Coupe, so say Audi, even though it looks like it could quite easily conquer the moon. Under the hood there's a mightily impressive 1.5L 3 cylinder TFSI engine with twin electric motors that provide it with 177 horsepower and 0 to 62 mph in 8.6 seconds. That coupled with its ultra-light frame makes this hybrid an environmental dream capable of 213 mpg.
