What I find slightly amusing is that when HyperCar was first making the headlines (what 2018-ish?) my very first thought was "Ah, cool...street based cars, wonder how they'll address LMP2 and GTLM". I didn't even give it that much thought because my assumption was that a major international automotive endeavor would have a vague plan for that. A plan that would be handled on time and logically.
From what I can see/hear they've handled it incredibly poorly, and worse, at the last minute. That's pretty garbage. They should have dictated a serious LMP2 performance drop far earlier. It's always easier to add back on horsepower/rev limits, etc.
Having said all that, I get it. We're in the usual "great breath before the plunge". The same thing we saw with IMSA and the Continental series before they revised classes/entries. We get one or two years or simply dire fields of cars, and one-off entrants, exceptions to the rules, etc.
I think in the end we're going to see LMDH (with its more...limited design scheme) subvert the actual HyperCar class in the next 4-5 years. Cheaper cars, with customer cars planned simply seems like the smart choice to me, particularly with the sudden additional financial burden caused by the "Das Kuef".
I think that around 2023 we'll hopefully have a stunning and unprecedented "top" class at LeMans. However it could be a rough 18-24 months before we get there. I hope we get there, regardless of how jumbled and messy the transition is.
The silver lining (in my opinion). Maybe, just maybe, we'll keep the LMP2's as close to the Toyota as they were. I'd actually love the LMP2's to be within 5-6 seconds per lap at LeMans (the last LeMans put LMP2 fastest laps almost exactly 10 seconds behind the Toyota Gazoo). I'd love to have a full class of squared away LMP2 cars waiting to inherit the race win if the HyperCars don't run perfect.
