The good news is Porsche-Manthey won the 2025 LMGT3 title! Manthey is going to run 2 911GT3 Rs in IMSA next year.
As far as Hypercar .... how can a team who has a shot at taking the season title suddenly be completely non-competitive? The answer: BoP. Porsche finished 13, 14, and 17 in their final WEC race

Nothing weird happened, they were just slow because they had HP taken away and weight added.
