Aerodynamic Designs of Front and Rear End Areas of Cars

With the conservation of energy becoming increasingly crucial, the efficiency of road vehicles requires an advance. The aerodynamic design of a road vehicle is responsible for its efficiency, especially the designs at the front and rear end areas. This paper focuses on the designs of the front and rear end areas, emphasizes the influences of these two areas on vehicle efficiency, and compares the improvements of optimizing parts in these areas. With alternations being made, the drag coefficient of the vehicle, which indicates the efficiency of that vehicle, can be reduced by at most 26%. In addition, the aerodynamic designs at the front and rear areas of classic vehicles and the current designs are introduced, followed by a description of the advantages of the new designs. Correspondingly, the drawbacks and limitations of nowadays designs are acknowledged, followed by the current challenges of the development of vehicle aerodynamics and the prediction of future designs.
