What are the benefits of losing weight by car? I brought you here to solve the problem of lightweight!

At present, the four most popular words in the former automobile circle are "lightweight, electrification, intelligence and networking". Although lightweight is not as easy to create a "topic" as the other three, automobile lightweight is still often said to be always new, keeping up with the global development trend, and China automobile industry is constantly breaking through the barriers in the field of lightweight and approaching the international advanced level.

The concept of lightweight comes from racing cars. Some research figures show that if the weight of the whole vehicle is reduced? 10%, can fuel efficiency be improved? 6%-8%。 Does the car body account for about the total mass of the car? 30%, under no-load condition, probably? 70%? Fuel consumption is used in the quality of the car body, so a lighter car body is of great benefit to the fuel economy, handling stability and collision safety of the whole car.

So, how much do you know about car lightweight? What are the benefits for ordinary car owners?

Lightweight is a breakthrough in the development of automobile industry and the beginning of a technological revolution. On the surface, it uses more expensive materials and processes, resulting in increased costs. However, from the overall analysis of product design and manufacturing process, the design difficulty of chassis, power and safety under the same vehicle performance is reduced, thus lowering the cost of these systems. Therefore, in essence, lightweight brings overall economic benefits to vehicle enterprises, rather than cost burden.

Increase fuel rate

Foreign experiments show that the fuel efficiency can be improved by 6%~8% if the vehicle weight is reduced by 10%, and the fuel consumption per 100 kilometers can be reduced by 0.3~0.6 liter if the vehicle kerb quality is reduced by 100kg. On the premise of keeping the overall quality, performance and cost of the vehicle unchanged or even optimized, reducing the vehicle weight can effectively improve fuel efficiency, thus achieving energy saving and fuel saving.

The automobile has a good energy-saving and fuel-saving effect, which is very beneficial to the owner's own interests and the environment.

Extend automobile life

After buying a car, it does not mean that the cost of the car is over, because the later maintenance, repair, insurance and other expenses need to be paid all the time, and the degree of wear and tear of the car is closely related to the weight of the car. Because the lighter the car, the lower the burden and wear on the tires, brakes, engine, gearbox and chassis suspension, so the possibility of damage is small and the frequency of maintenance is low. In short, under the same material and structural design, reducing the weight of the car can make the mechanical part more durable, which not only saves the owner's money, but also prolongs the service life of the car.

To sum up, the advantages of lightweight cars are obvious. It can not only reduce the expenses of car owners, but also improve the quality of cars, increase the driving pleasure of car owners and make a certain contribution to environmental protection.

But the price of lightweight materials is relatively expensive. In such a fierce automobile market, whether consumers are willing to pay the bill is also a big problem. Therefore, at present, lightweight is only applied to a small number of high-end models, and it has not been fully popularized. However, we believe that automobile lightweight must have immeasurable development potential and will become more and more popular in the future automobile development.
