I know. My point is that it could be better aero - for whatever reason - that more effeciently provides downforce for drag as Toyota have concentrated on Le Mans and got it sorted aero wise for two years now. Or it could be better mechanical grip so less aero is needed for the cornering speed. Or better engine/power deployment which allows more downforce, but still maintaining the top speed/acceleration needed.
Those characteristic could be explained by such things, but they could be explained by other aspects. So, I'm only certain enough to surmise that the Toyota is a better car.
