Hybrid-electric Vehicles
Hybrid-electric vehicles combine the benefits of gasoline engines and electric motors to provide improved fuel economy. The engine provides most of the vehicle's power, and the electric motor provides additional power when needed, such as for accelerating and passing. This allows a smaller, more-efficient engine to be used.
