Aerodynamic car design plays a crucial role in reducing drag, which in turn lessens fuel consumption. This study aims to investigate the effects of airflow around vehicles. This research simulated a 3D electric vehicle in unsteady conditions with various velocities, i.e., 10 m/s to 60 m/s. This simulation employs the standard k-epsilon turbulence model. The effects can be observed with qualitative data. The quantitative data measured include drag force and drag coefficient. The qualitative data presented in this paper consists of velocity contours, vectors, and pathlines, providing a clearer visual representation of airflow effects. The simulation results show that the drag coefficient decreases as flow speed increases, showing a percentage reduction of 25.09%. The average drag coefficient across the studied speeds is 0.481.
