Hybrids and plug-in hybrids have batteries and electric motors, along with gas engines. You can charge a plug-in hybrid and use only electrical power for a limited distance. With a regular hybrid, braking or coasting charges the battery and increases efficiency. Hybrids are more costly, but they don't need as much fuel as standard gasoline vehicles. Hybrid and electric vehicles are much quieter than conventional autos, and they have great acceleration as well. Some electric cars have front and rear trunks because they don't need the same engine space as a conventional car. Charging a car is also less costly than paying for gasoline.
