The light weight of a car means that the vehicle's maintenance quality is reduced as much as possible while ensuring the strength and safety performance of the car, thereby improving the power of the car, reducing fuel consumption, and reducing exhaust pollution.
The light weight of automobiles has a great impact on energy saving and emission reduction. For traditional internal combustion engine vehicles, each 10% reduction in self-weight can save 5% of fuel, reduce fuel consumption and reduce exhaust emissions, and ultimately reduce environmental pollution. The requirements for lightweighting of new energy vehicles are even more urgent. Studies have shown that the weight of pure electric vehicles can be reduced by 10kg and the driving range can be increased by 2.5km.
The lightweight of automobiles includes means such as lightweight structure, light weight of materials, and light weight of manufacturing processes. Among them, the light weight of the material is directly reduced by the application of new materials, and its effect in weight reduction is very obvious. This method plays an important role in lightweighting.
