what is a hybrid

A hybrid is a vehicle that uses two or more distinct types of power to move, such as an electric motor and a gasoline engine. The electric motor and gasoline engine can work together or separately to move the vehicle, and the system recaptures energy via regenerative braking. The battery pack in a hybrid vehicle is separate from the cars conventional 12-volt battery and is replenished by capturing energy from deceleration that's typically lost to heat generated by the brakes in conventional cars. The battery can also power auxiliary loads and reduce engine idling when stopped, resulting in better fuel economy without sacrificing performance. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. The advantages of a hybrid car include improved fuel efficiency, lower emissions, and reduced running costs relative to non-hybrid vehicles.
