Abstract: With the continuous popularization of new energy vehicles, battery life has always been the focus of people's attention. Reducing the air resistance during driving can effectively improve its range, and how to maximize the reduction of air resistance is the direction that the styling design field is constantly researching. This article first elaborates on the importance of car styling design and its relationship with air resistance, and then focuses on exploring the ideas and methods of maximizing the reduction of air resistance in the styling design process. That is, continuously optimizing and improving the styling features and conducting computer aided engineering (CAE) simulation analysis under the premise of meeting the styling design intention, and obtaining the final improvement plan through comparative analysis of CAE simulation results. At the same time, the main influencing factors of air resistance in styling design are summarized, and low wind resistance characteristics and recommended values are extracted, providing valuable experience and technical support for subsequent product styling design work.
