Abstract : A passenger vehicle experiences several resistive forces during its motion; the most prevalent being the aerodynamic and rolling resistive forces. A car is seen as a bluff body; which generally generates lift or very low down-force. Hence the present automobile technology focuses on optimizing the body surface geometry and/or adding aerodynamic devices to increase the tractive force of vehicle at relatively high speed. This tractive force assures improved vehicle handling and stability. This paper is based on the investigation of optimum wing profile and determining correct angle of attack and height to obtain maximum down-force to drag ratio without considerable increase in drag. The car model is taken of actual length scale, castellated-hexahedral structured mesh is used, turbulence model is selected as k-ℇ turbulence model and standard wall functions assuming steady flow in the domain. The wing is selected to be NACA 6412 at the stall angle obtained based on maximum down- force to drag ratio and its three different heights.
