Abstract

The global energy transition and carbon neutrality goals have driven the rapid development of new energy vehicles (NEVS), while traditional internal combustion engine vehicles (ICEVS) are also under pressure to improve energy efficiency. Aerodynamic design plays a vital role in improving vehicle performance by reducing drag and enhancing energy efficiency. This paper compares the aerodynamic design differences between NEVS and ICEVS, analyses their respective design challenges and strategies, and discusses common and unique aerodynamic optimisation methods. The paper explains the principle of the drag coefficient and its influencing factors and introduces two common measurement techniques—wind tunnel testing and the coasting method. By examining case studies of the Tatra 77 and Tesla Model S, it illustrates how streamlined design can effectively reduce drag, lower energy consumption, and increase driving range. The analysis demonstrates that although both vehicle types share some aerodynamic techniques, NEVS are shifting toward integrated and intelligent aerodynamic strategies, while ICEVS rely more on localised modifications. The findings provide theoretical support and practical references for designing future high-efficiency vehicles, contributing to the sustainable development of the automotive industry.
