Hybrid cars are vehicles that use two different sources of power: a traditional internal combustion engine and an electric motor. This combination allows them to be more fuel-efficient than conventional cars, as they can switch between or combine both power sources depending on driving conditions. These cars often have a battery that recharges while driving, especially during braking, which helps reduce emissions and save fuel. Popular models include the Toyota Prius and Honda Insight, which have gained attention for their eco-friendly features and lower operating costs compared to standard gasoline-powered vehicles.
