This paper systematically analyzes the key technologies, user demands, and policy environment that drive the innovation of exterior design for new energy vehicles. It explores core innovative elements such as closed front faces, intelligent interactive light language, aerodynamic optimization, lightweight materials and structures, and personalized colors and materials. It also looks forward to four major trends in the future exterior design of new energy vehicles: the widespread adoption of emotional and lifelike design languages, the extensive application of active aerodynamic systems,the deep integration of external user interfaces, and the comprehensive penetration of sustainable design concepts.
