In the future, the trends of global trade and manufacturing will continue in automobile. The next generation of automobile would be all electric. The future of automobile travel expert say may soon move away from all gasoline and diesel powered engines. In the future car themselves are incorporating more electric technologies instead of belts and carburetors of the past.

Future involves new breed of hybrid vehicles employ of two or more type of fuels and prime movers. An electric motor and battery driven vehicles is a hybrid vehicles. In hybrid vehicles solar energy also used. The use of solar energy in hybrid vehicles more advantages as compare to other.

The hybrid vehicles consist of hybrid system of power generation. The hybrid system are classified into two classes i.e. series hybrid system and parallel hybrid system. By using a hybrid system to achieving the revolutionary improvement in fuel economy such as highly efficient engine improved engine, operating range, engine shut off system, regeneration and reuse of braking energy, achieving smooth acceleration and deceleration.

Toyota hybrid system transmission of hybrid vehicles. The power interaction diagram of Toyota system transmission. Process of engine stopping, regenerative braking system, interaction of motors and hydraulics in Toyota hybrid system transmission. High expansion ratio cycle and Atkinson cycle in Toyota hybrid system transmission of hybrid vehicles. Advantages of hybrid vehicles such as better gas mileage, low harmful emission, little loss in house power, minimize fuel economy.

Technological advancement in hybrid vehicle, Such as increases battery capacity and use of more powerful electric motors. Disadvantages of hybrid vehicles. Future application of hybrid vehicles in big rigsand semi trucks, mass transmit vehicles such as buss and race cars etc. comparison between gas powered vehicles and hybrid vehicles.
