Built on the same Voltec platform as the Chevrolet Volt, the Ampera is an Extended-Range Electric Vehicle that will travel up to 60 km (37 mi) on electricity from its battery pack before a gasoline engine kicks on to generate electricity to power the wheels. The battery pack will recharge from a standard 230-volt outlet and is expected to provide more than enough power to allow most European drivers to make their daily commute without the gasoline engine ever starting up. According to GM's research, 80% of German drivers travel less than 50 km per day.
