DETROIT - Ford Motor Co. is investing an additional $450 million in its aggressive electric vehicle plan, paving the way to build a next-generation hybrid and plug-in hybrid vehicle in Michigan beginning in 2012, the automaker announced.

Ford's Michigan Assembly Plant in Wayne, Mich., will be the production site of hybrid, plug-in hybrid and full battery electric vehicles, all of which will be built off the company's new global C-car platform.

In addition to building the Ford Focus Electric and next-generation hybrid and plug-in hybrid at Michigan Assembly Plant, Ford will design advanced lithium-ion battery systems in-house for the next-generation hybrid in Michigan and move production of the battery packs from Mexico to Michigan.
