Mild hybrids are vehicles that use a combination of a traditional internal combustion engine and a small electric motor. Unlike full hybrids, mild hybrids cannot drive solely on electric power; instead, the electric motor assists the engine, improving fuel efficiency and reducing emissions. This system allows for smoother acceleration and helps recharge the battery during braking. The electric motor in a mild hybrid typically works in conjunction with a start-stop system, which turns off the engine when the vehicle is stationary and restarts it when the driver accelerates. This technology is becoming popular among automakers as a way to meet stricter emission regulations while providing a more efficient driving experience.
