Prospect of Automobile Aerodynamic Drag Reduction External Structure (AADRES) for Electric Car

Abstract

AADRES has been further optimized over the past hundred years for diminishing fuel consumption, yet there is still a sharp reduction in traditional energy around the world. Recently, the energy structure of automobiles has also been transforming from gasoline power to electric power in order to save energy and reduce the CO2. However, electric cars have one fatal problem which is battery capacity. Therefore, AADRES should be redesigned for electric cars. In order to find an AADRES suitable for electric cars, this paper briefly explains the resistance principle of cars and instances some existing aerodynamic drag reduction methods. By analyzing and identifying those methods, a personal scheme of new style AADRES for electric cars is also presented, which primarily follows the wedge car shape but incorporates a deflector, embedded door handle, and pitted non-smooth surface while removing door mirrors.
