Hybrid synergy drive explained

Hybrid Synergy Drive operation in normal conditions:

Stopped

When the car is stationary, such as at traffic lights, the petrol engine generally switches off, saving fuel and reducing emissions.

Start-up and acceleration

Under very light acceleration or when in reverse, the electric motor is the primary power source.

Normal driving

The petrol engine and electric motor drive the wheels. Surplus engine power is stored in the battery.

Heavy acceleration

The battery supplies additional energy to boost drive power.

Coasting and braking

The electric motor acts as a generator, driven by the car’s wheels. Kinetic energy that is normally lost as heat during braking is converted into electricity and stored in the battery.

Seven facts about Hybrid Synergy Drive technology

1. Hybrid Synergy Drive technology combines an efficient petrol engine, a nickel-metal hydride battery and an electric motor.
2. The system makes the most efficient use of these power sources, significantly reducing fuel consumption and CO2 emissions.
3. The battery is recharged while driving and can store kinetic energy generated during deceleration and braking.
4. The rechargeable battery is designed to last the vehicle’s lifetime.
5. A Hybrid Synergy Drive vehicle drives like any other automatic vehicle. Hybrid vehicles are now becoming popular rental cars in Australia.
6. Toyota hybrid vehicles can be driven short distances on electric power only.
7. Toyota believes Hybrid Synergy Drive is a core technology that will play a prominent role in the car market
