A hybrid relies on two sources of energy to power the vehicle's movement: a traditional combustion engine, and a larger-than-normal electric battery. A good hybrid will help fuel economy by charging the battery during downhill driving and braking by transfering energy from the motion of the car's wheels and heat from the car's brakes. Not all hybrids do this, however. At the very least, a hybrid will shut off the gas engine whenever the car is stopped. For a more complete description of how a hybrid works, see the Wikipedia entry below, or check out Toyota's Hybrid Synergy Drive minisite.

A hybrid car uses an electric motor/generator to assist the gasoline engine in acceleration. The electricity to drive the motor is recaptured from the energy normally lost in stopping the vehicle. In a normal car, the energy of the forward momentum of the car is converted into heat when the brakes are applied. A hybrid car captures that otherwise wasted energy, and converts it into electricity to drive the electric motor that assists the engine. As a result, the gasoline motor is required to put forth less effort to drive the car, which means less fuel is consumed. Also, hybrid cars use other tricks to reduce fuel consuption, such as shutting off the motor when the car is stopped, and sometimes employ continously variable transmissions (CVTs) to further boost fuel economy.

A hybrid uses the energy that is released when you break to charge the battery of a car, it also uses some fuel. They are usually very fuel efficient.
