The Audi e-tron won our hearts the second we laid eyes on it. This all-electric vehicle was our favorite concept car that came out of the Detroit Auto Show this year. We’ve always been fans of Audi’s design and we think this electric concept could take Tesla’s supercars down a notch or two. The Audi e-tron is an all-electric vehicle, powered by a pair of electric motors producing 201bhp that can get to 62mph from standstill in just 5.9 seconds. The 2010 Audi e-tron’s top speed is limited to 124mph due to the battery life and it has a maximum range of around 155 miles.
