Final Drive Ratio Analysis

To determine the most efficient and quickest final drive ratio (FDR) for the car, simulations must be performed prior to manufacturing
As a team, a FDR of 4 was chosen each year, but we needed to further reinforce this with additional data

Using both open source MATLAB code named OpenLap and a software named OptimumLap, the final drive ratios were simulated in multiple batches
Implemented 2026 vehicle parameters, including weight, suspension spring rates, aerodynamic CL/CD, brake balance, and motor maps

OptimumLap produced data which suggested fastest lap times for endurance occur with a FDR of 4
OpenLap suggested a slightly higher FDR of approximately 4.15
