汽车轻量化是在保证汽车整体品质和性能不受影响甚至提高的前提下,尽可能降低汽车产品自身重量,从而更好地发挥汽车的动力性,减少燃料消耗,降低污染排放。轻量化的商用车不仅可以带来更好的操控性,而且可使发动机输出动力产生更高的加速度,起步时加速性能更好,刹车时制动距离更短。从节能环保意义上 Car lightweight is to ensure that the overall quality and performance of the car is not affected or even improve the premise, as much as possible to reduce the weight of automotive products, so as to better play a car’s power, reduce fuel consumption, reduce pollution emissions. Lightweight commercial vehicles not only provide better maneuverability, but also make the engine output power higher acceleration, better acceleration at start, shorter braking distance when braking. From the energy saving and environmental protection sense
