Electric, Nano Goes Diesel

The electric Smart ForTwo, known as the Smart ed, has a 41-hp electric motor and sodium-nickel-chloride batteries. It gets about 70 miles per charge, and has a maximum speed of 70 mph, which makes it a reasonable commuter EV, even if your commute involves highways. Price and market haven�t been announced, but they do expect it to go on sale in 2010. Cross your fingers that it comes your way � and you can afford it.
