| Abstract: | The lightweight design of automobile has great economic, social and environmental benefits,wherein the lightweight of vehicle body plays an important role. New energy vehicles need to carry highcapacity power batteries to increase the driving range while also ensuring battery safety. The requirements for the vehicle body include providing ample space for battery pack installation, ensuring the safety of both passengers and batteries in the vehicle, and incorporating lightweight design consideration. These goals have brought many challenges to the vehicle body design and development. The paper focuses on an electric sports sedan that, thanks to the implementation of some key lightweight design and manufacturing technologies,has achieved excellent collision safety ratings, including C-NCAP five-star and C-IASI green, as well as the industry-leading lightweight coefficient of 2.03. |
