A mild hybrid electric vehicle (MHEV) is a type of vehicle that combines an internal combustion engine with a small electric motor to enhance performance and efficiency. Unlike full hybrids, MHEVs cannot operate solely on electric power; instead, the electric motor supports the gasoline engine during acceleration and other driving conditions, improving fuel economy and reducing emissions.

MHEVs utilize regenerative braking to capture energy that would otherwise be lost during braking, which helps recharge the small battery. This technology enhances performance and reduces emissions compared to traditional vehicles without requiring external charging. Mild hybrids typically feature a simpler and more cost-effective hybrid system, making them an attractive option for drivers seeking improved fuel economy and lower emissions without the complexities of plug-in charging. Overall, MHEVs deliver a seamless driving experience with enhanced efficiency while maintaining the convenience of a conventional vehicle.
