Tesla Motors
"Going green" doesn't have to be boring. The Tesla Roadster Sport is an electric car that goes from 0 to 60 in four seconds and drives more like a race car than an environmentally friendly ride. But that level of performance will set you back $128,500. As of 2009, Silicon Valley-based Tesla Motors, Inc. was the only company offering highway-compatible electric cars. Most Roadster Sport buyers are car enthusiasts and are buying them for the "fun toy" aspect of having an electric car rather than for environmental reasons.
