Hybrid vehicles combine the power of an electric motor and a gasoline or diesel engine.
- Hybrid vehicles work better at different speeds; The electric motor is more efficient at producing torque or turning power and the combustion engine is better for maintaining high speeds.
- Mopeds are simple forms of the hybrid, which are powered by an internal combustion engine or electric motor.
- In a parallel hybrid vehicle, an electric motor and an internal combustion engine are coupled such that they can power the vehicle either individually or together. Most of the combustion engine, the electric motor, and gearbox are coupled automatically controlled clutches.
- For electric driving, the clutch between the internal combustion engine is open while the clutch to the gear box is engaged. While in combustion mode the engine and the motor run at the same time.
