Audi has unveiled an interesting and very sleek new concept car called the Audi Urban Concept. This car is intended to show what the future of small and very fuel-efficient cars for city dwellers might look like. The car is dubbed a 1+1 by Audi and is made to be as lightweight as possible. The lighter a car is, the more performance it offers with less power and the longer the driving distance is since the car runs on batteries. The car was shown off at the International Motor Show in Frankfurt.
