Recent trends in aerodynamic performance developments of automobile vehicles: A review

Today aerodynamics of automobile engineering plays a vital in both industry and as well as in research labs. The performance of any automobile vehicle purely depends on its internal and external aerodynamics. To accomplish better performance in the field of automobile engines all the aerodynamics factors must satisfy the design requirements. This review article emphasis more on two broad categories one is heavy good vehicles and second one is lighter vehicles. Both the classification required different aerodynamic shapes and design requirement. Therefore, further this article focuses into more on reduction of drag on vehicle, vehicle aerodynamic instabilities and its possible solutions, design optimization of vehicles which involve finding out the areas that need improvement in the existing designs and looking at some new concept designs. Further to the upcoming researchers this paper also helps in providing the information on recent trends in aerodynamic performance developments of automobile vehicles.
