When Audi unveiled the original e-tron Concept at the last Frankfurt Motor Show in 2009, a production version seemed to be nothing more than a glimmer in the very distant future. Two years later, it appears that the automaker has made plenty of progress in bringing an electric-powered R8 into the world.

Fast forward to 2011, Audi revealed a new R8 e-tron "technology demonstrator" that represents something fairly similar to the production model we'll see in the near future. Some unique visual features separate the R8 e-tron from the petrol-powered version, including the carbon fiber vents on the hood and chrome slats in the front grilles and rear bumper. Like the concept, the production version of the car is expected to feature four electric motors sending power to each wheel, with performance targets including 0-60 mph in less than five seconds and a 150 mile range.
