A hybrid car is a vehicle that uses two different sources of power to operate, typically combining a traditional internal combustion engine with an electric motor. This design allows the car to be more fuel-efficient and produce fewer emissions compared to conventional gasoline-powered cars. The electric motor is powered by a rechargeable battery, which is charged through regenerative braking and the engine itself. Hybrid cars, such as the Toyota Prius, are popular for their ability to save on fuel costs while reducing environmental impact.
