A hybrid vehicle is a car that runs on two types of power: gasoline and electricity. Gasoline powers the engine, which runs the car, and electricity powers the battery, which helps the engine run more efficiently. Both types of power work together so that the car uses less fuel, meaning you don't have to fill up your tank as often. And because hybrid cars use electricity to power part of the car, they often produce less pollution than regular cars, which is better for the environment.
