Abstract
One of the process of the development of the car is in the production of the body, the development is intended to look for a more aerodynamic body so that the body gets smaller resistance. This innovation is certainly developed to follow the electric car competitions are classed both nationally and internationally. In this research, aerodynamic analysis on the surface of the electric car body "Mandalika EV" uses Autodesk CFD 2016 software which aims to know the fluid flow pattern and the value of drag coefficient of electric car "Mandalika EV" which already exist with variation of car speed that is 70 km/h and 100 km/h, while on the front side of the body shape variation of the angle of attack is 25°, 30°, 40° and done variations on the side of the body with a flat, convex and concave. So that later will be taken part that has the smallest drag coefficient and then combined into one body shape. The results showed that the coefficient valueon the combined car body obtained a value of 0.6152 so that there is a decrease of 10.67% with a speed of 70 km / h and 0.6179 using a speed of 100 km / h a decrease of 10.69%.. By modifying the angle of attack on the front of the car body and change the dimensions of the size of the side of the car body can reduce the value of drag coefficient received by the car body.
