2013 Audi Sport Quattro Concept

Audi's classic rally car celebrates its 30th birthday at this year's Frankfurt Auto Show with the debut of the Sport quattro concept. An evolution of the quattro concept that was shown three years ago, the Sport quattro is powered by a plug-in hybrid system consisting of a twin-turbo V8 and an electric motor that pushes out 700 hp, a 0-62 time of 3.7 seconds, and a top speed of 189 mph. And don't let the supercar-level numbers fool you, the car is nothing but efficient, the car has a range of 31 miles on electric power alone and has an impressive fuel rating of 94 miles per gallon.
