Mitsubishi will showcase a concept version of its MiEV Sport Air, an all-electric sports car, at the Geneva Auto Show taking place the first two weeks of March. There aren't a lot of details at the moment. It will be powered by lithium-ion batteries places in the floor. This will give the car a low center of gravity. It is also shaped like an egg. "Greetings, Earthlings. We come in peace," you can tell the valet after driving up in this rig. "Together, these features along with the car's clear cutaway top allow the driver to enjoy the exhilaration of fresh air motoring while also highlighting its eco-friendly qualities," the company says. Sports cars could be the first large market for electric cars. Because of the nature of electric motors, it's easier to get rapid acceleration out of an electric car. That's why Tesla Motors started with a sports car and why the Tesla Roadster and the prototypes created by Wrightspeed, two very young companies, already rank fairly high up in the zero-to-60 miles per hour tests. Sports car buyers are also less concerned about price and the number of miles the car will go on a charge. A lot of sports car owners don't commute with these cars, so they don't need to go 300 miles on a charge.
