Introduction A hybrid car is a car used to drive the drive wheels more than one source of energy. Modern car manufacturers often resort to sharing of the internal combustion engine and an electric motor, which avoids the mode of the internal combustion engine in low loads, and also to realize the recovery of kinetic energy, increasing the fuel efficiency of the power plant. Another common type of hybrids is vehicles, in which ICE is combined with engines running on compressed air.

It should be distinguished from hybrids vehicles with electro-mechanical transmission, such as locomotives, some tractors and tanks.
