GM spokeswoman Michelle Malcho told the Freep that, "We're really seeing momentum continuing to build. As people see their neighbors have one and as they start to understand the technology and are able to drive it, they put it into their consideration." Malcho said California residents buy a third of all Volts, and Michigan is also a strong sales market.
We heard recently that the GM plant that builds the Volt in Hamtramck, Michigan will be idled for a month starting in the middle of September, either to retool the machines or balance out supply and demand or a little bit of both. Currently, GM is building both 2012 and 2013 model year Volts "to accelerate the transition to the new model."
