Hybrid vehicles are cars that use two different types of power sources to operate, typically combining a traditional internal combustion engine with an electric motor. This design allows them to be more fuel-efficient and produce fewer emissions compared to conventional vehicles. The electric motor can assist the engine during acceleration or operate independently at low speeds, which helps save fuel. These vehicles often feature a rechargeable battery that stores energy generated during braking or from the engine. Popular examples of hybrid vehicles include the Toyota Prius and the Honda Insight. As technology advances, hybrids continue to evolve, offering improved performance and environmental benefits.
