General Motors unveiled the Opel Ampera extended-range electric vehicle in Geneva on March 2, 2009. The five-door, four-seat Opel Ampera will use GM's electric propulsion technology called Voltec, which operates differently from other advanced propulsion system. For trips up to 60 km, the Ampera will run only on lithium-ion battery power charged via a standard 230v outlet. For longer distances, the car will continue to drive on electricity that is generated by a small internal combustion engine and lasts for hundreds of kilometers.
