Summary:This project involves analyzing the aerodynamic parameters of the vehicle and proposing the necessary changes in design to obtain better fuel economy and speed. The original, popular model was modified by the addition of spoilers, front splitters, vortex generators, diffusers, side skirts and front air dams. The popular model and the modified model are compared with respect to velocity contour, velocity streamline contour, velocity vector. It has been found that for the modified model the drag co-efficient can be reduced by 34 % and the downward force can be reduced by 19 %.
