Aerodynamic characteristics of racing car are of significant interest in reducing racing accidents due to wind loading and save the fuel consumption. This work outlines the process taken to optimize the geometry of a vehicle. Vertices and edges of car were imported into GAMBIT and a computational domain is created. An unstructured triangular mesh was then applied. The goal is to obtain a better flow around the car model to lower the coefficient of drag force; the work is carried out in a ANSYS CFD FLUENT program towards a converged solution. These practices are helpful to redesign existing vehicles in order to improve handling and increase fuel efficiency. In the present work an attempt has been made by considering three models of car by varying speed of vehicle, the pressure coefficients and drag coefficients are obtained.
