Despite uncertainty, automakers are still making a big push for electric vehicles in 2012. Ford, for example, will have five such cars by the end the year, including the 2013 Ford Fusion hybrid and 2013 Ford Fusion Energi plug-in electric, which were both shown at last week's Detroit auto show. Although hybrid and electric car sales have been on the rise in recent years, some say consumer demand could wane, especially due to low gas prices and cheaper technology that favors internal combustion engines. EV-friendly tax credits have also expired. In 2025, Corporate Average Fuel Economy (CAFE) regulations will force automakers to make cars that attain 54.5 miles per gallon on average.
