Hybrid cars are vehicles that use two different sources of power to operate, typically combining a traditional internal combustion engine with an electric motor. This combination allows them to be more fuel-efficient and produce fewer emissions compared to conventional cars. The electric motor can assist the engine during acceleration or operate the vehicle at low speeds, reducing the amount of gasoline consumed. These cars often feature a rechargeable battery that stores energy generated during braking or from the engine. Popular models include the Toyota Prius and Honda Insight, which have gained attention for their eco-friendly design and cost savings on fuel.
