Electric vehicle
A hybrid electric vehicle (HEV) has both an internal combustion engine and an electric motor which drives the wheels. Usually, the electric motor is used when moving at low speeds and power from the internal combustion engine is used as the car goes faster. The engine get its power from gasoline, diesel, or any other kind of fuel, and can generate electricity which is stored in batteries to be used later with the electric motor. The battery is much smaller than that of a pure electric vehicle and even though the vehicle can go without starting the gas engine, it cannot go very far before the battery runs out of energy and the gas engine has to be started. The Toyota Prius is the best-selling HEV of all time, but many other companies around the world like Honda (with the Clarity), BMW (with the i3), and Ford (with the Focus) also make hybrid cars, some of which, such as the Honda Civic and Toyota Camry, come in both gas-only and hybrid versions. The hybrid version is usually more expensive because it has more parts.
