In this work, a detailed study has been done to investigate flow of air over the vehicle and various methods have been discussed to check the effectiveness in particular cases, methods like vortex generators, guided vanes, tail plates, rear spoilers, angled diffusers, rear under body slicing ,splitter plates and exhaust gas redirection have been reviewed. The main aim of the review study was to know the factors affecting Coefficient of drag and lift. Of all mentioned techniques and methods, vortex generator and tail plates were found more effective in reducing the drag coefficient as well as the lift coefficient. The study proposed that CFD methods application is proving to be an effective method of improving aerodynamics of a vehicle.
