“Balance of performance (abbreviated BoP) is a regulation and mechanism that maintains parity between competing vehicles by adjusting limits on a car's parameters, such as horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from becoming dominant in a racing class or series.” The aim of this paper is to study and understand the current rF2 GTE BoP. All 5 cars (Ferrari, Porsche, Chevrolet (C7R), BMW, Aston Martin) have been compared using raw numbers and formulas. Cars were set to be in the most similar conditions. Lowest front height combined with lowest springs and wing were used to bring the car to their limit of aero-efficiency and top speed. Wing 1 (minimum) is also the most used configuration in top competitions so it is the most significative configuration to measure. No measure were performed on driver-dependant data (such as top speed in a short straight, pure acceleration, corner Gs) to avoid human influency on final results. Ferrari 488 is used as reference for every single graph display, as using the same car for every compare makes it easier to understand data differences. Edit to V2 (08/01/2020): - Changed Cd and Cl to CdA and ClA (just a name change, nothing new in numbers). - Changed C/L in L/D (that was just a mistake in naming the parameter, it is still ClA/CdA). - Added change notes in BoP proposal to better understand it. Edit to V3 (10/01/2020): - Removed every VEC reference from the paper. - We reached over 320 downloads, thanks you all for spending a bit of your free time reading our paper!
