Hybrid Drive refers to a type of vehicle propulsion system that combines two or more different sources of power, typically an internal combustion engine and one or more electric motors. The term can also refer to a specific technology used in vehicles with regenerative braking systems, where the energy lost during braking is captured and stored for later use, extending the range of the vehicle's battery. In summary, Hybrid Drive refers to any system that uses both gasoline or diesel power and electric power to propel a vehicle.
