This is the second piece of news in less than a week that suggests GM is seeing greater demand for its plug-in than anticipated. Last week, two unnamed sources told Bloomberg Businessweek that GM CEO Dan Akerson wanted to increase production of the Volt to 120,000 cars next year. To put that number in context, GM plans to build 10,000 Volts this year. GM's original 2012 target was 30,000 Volts; last July, apparently feeling feisty, they bumped that number to 45,000. So 120,000 Volts would be a major jump, and we're particularly curious how LG Chem, the Korean company that builds the car's lithium-ion battery cells, will handle the demand.
