Pat Davis, who heads the vehicle technologies program for the U.S. Department of Energy, said automakers' plans for ramping up electric vehicle production puts the nation on track to top President Obama's goal of 1 million electric vehicles on the road by 2015.
"It's clear that by 2025, to meet the new fuel [efficiency] requirements, that we are going to see more electrification than we have now," Mr. Davis said. "That is going to take the form of everything from micro-hybrids to full hybridization plug-ins to electric drive. But they will not be the only thing on the road. You will probably see more natural gas vehicles than you have today, and vehicles with downsized engines and lighter vehicles than today."
