The objective of this study is to determine the value of drag coefficient and lift coefficient against variations of speed of 5.5 m/s, 8.3 m/s, 11.1 m/s, 13.8 m/s, and 16.6 m/s. This simulation analysis is carried out using the Comptutational Fluid Dynamic (CFD) method as a means of simulation. From the influence of aerodynamics, the Drag Force on the Body, Lift Force, Coefficient of Drag, and Lift Coefficient, the smallest value is 40.715368 N at a speed of 5.5 m/s, and the largest value is 365.3591 N at a speed of 16.6 m/s. The body's coefficient of drag decreases at a speed of 16.6 m/s, resulting in a value of 1.2883, and the highest value is 1.2922 at a speed of 5.5 m/s. The lift force then experiences down force, with a low down force of -1.0805453 N at 5.5 m/s and a high down force of -10.429573 N at 16.6 m/s. On the other hand, the lift coefficient increases, with a value of -0.03429 at 5.5 m/s and a value of - 0.03682 at 13.8 m/s. From the effect of aerodynamics on speed variations, the coefficient of drag tends to decrease but the value is constant with a value of 1.2. And for Drag Force increases significantly. And for the value of the coefficient of lift tends to be constant with a value of -0.0 and for the Lift Force (Down Force) increases.} }
