As the reality of the all electric Nissan Leaf draws nearer, expect to see a lot more all-electric vehicles, concepts, drawings and promises. One is the Audi e-tron, and all electric, high performance coupe that looks like a smaller version of the R8 - it's a real car but just not for US buyers. Recently, Audi entered the car in a 100+ mile rally. A high performance electric car may seem silly but Mercedes Benz says a battery powered SLS could be a reality and the Tesla Roadster is fairly quick without the help of a gasoline engine. BMW is also working on an all-electric car based on what the company learned from the Mini-e. The luxury hybrid Fisker Karma is also on the way and Tesla promises a four-door, all electric performance sedan. Also look for Mitsubishi's electric i-Mieve and of course the Chevrolet Volt is on its way.
