可以这么理解。驾驶这款车时，用的是发动机的动力，烧的是汽油。而当您等红灯或者塞车的时候，动力就由电池来供给。这样不仅省油，而且大大地减少了尾气排放对环境的污染。

Haha, you could understand it that way. When you drive this car, you're using the engine's power and what's being burned is gas. But then, when you're waiting at a red light or stuck in a traffic jam, the power is supplied electrically. This way, you not only save fuel, you're also reducing exhaust emissions in a major way.
