When General Motors unveiled the Opel Ampera at the Geneva Motor Show last March, employees at Vauxhall got their hopes raised that they would eventually get to build the sibling of the Chevy Volt. Last year, it looked like Voltec-based vehicles could find a home at Vauxhall's Ellesmere Port factory thanks to some British government incentives. That wouldn't have happened at the start of production anyway because initial volumes will likely be too low to support two factories. However, the recent agreement to sell Opel and Vauxhall to a group led by Magna International means that is unlikely to ever happen. For the foreseeable future, any and all variants of the Volt will be sourced from the Detroit-Hamtramck assembly plant.
