The design was done to minimize the drag force.Thisstudy was conducted using numerical simulations and the target value of the desired drag coefficient wasless than 0.25 (CD<0.25). The simulation were done using ANSYS Fluent 17.2 on 3D car model. This 3D car model will soon become a participant of KontesMobilHematEnergi(KMHE) in 2018. The Reynolds number tested were between 1,283,601 to 2,139,334. There were 3 initial body designstested to obtain the body design with the lowest CD value. The JM-4 body design initial was the best initial body design with a CD value of 0.173. The best h/L ratio for JM-4was 0.018 with a ground clearance of 50 mm and a body length of 2750 mm. The h/L ratio resulted in a CD value of 0.173 and a negative of CL value of 0.246. Themodification of shapeand frontal area of JM-4 managed to reduce the value of CD by 4.04%.The resulting modified design was called JM-4v3.1. The installation of airfoil-shaped tyre axis proved to be best and only increased the CD value by 9.63%.The use of the front and rear wheel covers successfully decreased the value of the CD from before the wheel cover was applied. The front wheel cover of DF3 type reduced the CD value by 15.03% compared to the uncovered front wheel. The car design that had been fitted with DF3 called JM-4v3.1 DF3. While the rear wheelcover type DR2 managed to reduce the CD value by 3,4% of the design of JM-4v3.1 DF3 car. The lowest value of drag coefficient (CD) obtained from this research was 0,235 of a car design called JM-4v3.1 DF3R2. The wool tuft visualization was performed at the wind tunnel ofBBTA3PUSPITEKSerpong showed that the CFD simulationswas qualitatively correct and the final design of the JM-4v3.1 DF3R2 was the best design.
