Formula Student is a competition held on yearly basis in multiple countries around the world. Students from different universities participate in this competition implementing some of the most sophisticated techniques in design and analysis of Formula Student car performance. In this research a track simulation tool is developed using Python to analyze the effect of different systems on the car performance, and to test the performance of the car on the Autocross track. For simplicity, the car is modeled as point mass in straight roads and corners. Intensive studies were carried out leading to a conclusion that, in some cases, point mass modeling leads to some inaccuracy and in others it provides the solution. Therefore, to achieve simulation accuracy, the point mass model was replaced with four degrees of freedom, or “bicycle”, model counterpart when it couldn’t provide an accurate solution, and the difference between both models results are discussed. The brake bias ratio selected for the brake system versus human force applied on the brake pedal was optimized and the optimization technique is discussed along with whether or not it should be track layout dependent. Car with and without wings performance were compared, and the effect of the aerodynamic devices on the car on straight roads, in corners and on its braking capability is also shown. Since a car with given specifications will have different performances on different tracks, the effect of different race lines on the car performance was briefly shown for a car going through a 90-degree turn.
