The present research study examines the aerodynamic behavior of a Suzuki Forsa vehicle with a racing airfoil. The ANSYS Fluent software and the RANS K-ε turbulence model are used to perform a numerical simulation. A coarse and a refined mesh are used to design the airfoil. The data is validated with the refined mesh by using a normalized wall distance (y=5) and an inflation rate of 1.20. This configuration is used to perform computational fluid dynamics simulations with different angles of attack (5o, 10o, 15o, and 20o). The simulation time was 10 hours for the proposed angles of attack. The results show that the 20o angle of attack provides an adequate negative sustentation force (aerodynamic force) to improve tire grip with tread surface and achieve the most efficient aerodynamic. It is concluded that the 20o angle of attack configuration provides the most downforce and the most efficient aerodynamic configuration for Suzuki Forsa vehicles.
