xiety for many carmakers is the plug-in hybrid, an electric car with a backup gasoline engine. The Chevrolet Volt, the Toyota Prius Plug-In and the Ford C-Max Energi all use electric power for the first 20 to 5o miles (or most daily trips) and then switch to gasoline for longer drives. 3. Charging is a headache.
