So there's the LMP1-P/LMP1/LMP1-Non-Hybrid/LMP1-Privateer/(former) LMP1-L sub category... easy as pie
It just struck to me that the real reason they might've actually axed initial 'L' and pretended that they've re-unified the P1 class is because they went to 850kg from 800kg in order to equalize overweight Kolles and lighter Rebellion. Obviously they haven't done what Oak's Nicolet wanted = distinctive one class
