< Back Hybrid Vehicle A vehicle that combines a gasoline engine with an electric motor. Hybrid vehicles use both an internal combustion engine and an electric motor to improve fuel efficiency. The system automatically switches or blends power sources depending on speed and load. Regenerative braking converts kinetic energy into electricity to recharge the battery. Hybrids reduce fuel consumption and emissions without needing external charging. Full hybrids can run short distances on electricity alone, while mild hybrids assist only during acceleration. They bridge the gap between traditional and fully electric vehicles, offering efficiency with convenience.
