Opel will unveil its version of the revolutionary Chevrolet Volt at the 2009 Geneva Motor Show in March. The extended-range electric vehicle, which Opel will call the Ampera, will be a five-door, four-seat model that shares styling cues with both the Volt and last year's popular Flextreme concept. The Ampera is similar in size to the Saturn Astra. GM's ground-breaking electric propulsion technology, called Voltec, operates differently from other advanced propulsion systems. For short 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. According to the press release that accompanied that teaser photo above, approximately 80% of German drivers travel less than 50 km daily. Additional information about the Opel Ampera will be released March 3rd.
