Ford mulling plug-in hybrid vehicle.
DEARBORN, Mich. - Ford Motor Co. is considering the development of plug-in hybrid vehicles in an effort to provide alternate energy sources, the director of the automaker's hybrid program said on Tuesday. Speaking at the Automotive News World Congress in Dearborn, Michigan, Nancy Gioia said the automaker is considering adding plug-ins products, but the biggest challenge in development is battery technology. "The biggest barrier is the battery," Gioia said. Plug-in hybrids use a battery as the main source of energy and can be recharged at electrical outlets.
