AC Propulsion's tzero roadster is a reason to not give up on the electric vehicle. The tzero does 0 to 60 mph in 3.6 seconds, according to the company, and it does it on only 200 horsepower because of its light weight and torque.

The San Dimas, Calif.-based company says the tzero (pronounced "tee-zero," not "chair-o") has compared favorably in acceleration tests to Corvettes, Porsche 911s--and even a Ferrari F355, which it claims to have "out-accelerated...by eight car lengths" in one-eighth-mile drag races. If for nothing else, the tzero's $220,000 sticker price puts it in exotic-car territory.
