One technology to improve fuel efficiency and ensure better vehicles at high speeds is to consider aerodynamic forces. The coefficient of drag and less lift can minimize the big engine work due to the air fraction so that it could be saving fuel. The geometry is simulated in a vehicle prototype. Three-Dimensional (3D) computational analysis was carried out using SolidWorks as modeling and Ansys as the pre-processing, solver, and post-processing. The speed is varied at (v) 10 m/s, 20 m/s, 30 m/s, and 40 m/s. The simulation results showed that the coefficient of drag has under 0,08. The value of the drag and lift coefficient of the average simulation results is 0,072 dan -0,00345 respectively. This result indicates that the design of the Marapi Evo 1 vehicle has an aerodynamic shape. This is impact the saving of fuel usage. The best drag coefficient value is at a high speed of 40 m/s.
