Hybrid Synergy Drive® is a collection of innovations, technological advances and design features built around an engine that switches automatically between petrol combustion and battery power to drive the car in the most fuel-efficient, environmentally clean way for any situation. When the car is stationary the engine even switches itself off, 'til it's needed again. And when you brake, the car stores energy that's normally lost in deceleration, to use later. It's very clean and it's very clever.
