Lightweight is an important challenge currently faced by the automotive industry, and many host manufacturers have made significant research and development investments in this topic. Although they have achieved great success, the average weight of cars has decreased by 50% compared to fifty or sixty years ago. However, there is still a lot of room for further exploration in lightweight technology.
In the "Made in China 2025" jointly released by national ministries and commissions, lightweight has been regarded as an important direction for the development of the automotive industry. When energy conservation and emission reduction become an inevitable requirement for the current automotive industry, automotive lightweight is of great significance for energy conservation and environmental protection. Next, we will introduce the relevant content of automobile lightweighting, as well as the ways and methods of automobile lightweighting, and analyze the impact between automobile lightweighting and safety.
