Do hybrid cars get power through kinetics?

Hybrid cars are fuel-efficient vehicles that get fantasticgas mileagethrough the combined use of new technology and simple physics.Aerodynamicbodies, for instance, create much less air resistance as the car moves down the road, and lightweight materials only further the effort. The tires on hybrid cars are often the low-rolling-resistance type, and even the simple act of stopping the car is more efficient, too. You see,regenerative brakingallows the vehicle to capture its own kinetic energy to increase fuel efficiency.

用最简单的术语说，动能是运动的能量。任何移动的东西，例如汽车的轮子，都具有动能。在混合动力汽车或任何汽车上的车轮的具体情况下，动能是旋转的 - 众所周知（请在阅读下一行时随意唱歌），汽车上的车轮也可以一遍又一遍。

Most hybrid cars on the market today have regenerative braking systems that make good use of this kinetic energy. Regenerative braking systems can be used by full hybrids, which can operate in all-electric mode for short periods of time, or bymild hybrid vehicles, which make use of advanced systems likeidle-stop technology, sometimes called start-stop technology. But regardless of the specific type of hybrid vehicle, full or mild, they both benefit from regenerative braking.

Anytime a vehicle can use energy other than gasoline, including kinetic energy, the fuel efficiency of that vehicle will increase. Up next, let's take a closer look at how regenerative brakes make eco-friendly driving possible.
