For LMH - how do they differentiate from the older LMP1 cars? They all end up looking the same... Do they need to produce X amount of road cars to homologate these ones?
That's a great question. Not by much is the answer. The LMH rulebook actually has sections with slightly different rules for prototypes vs production based models. Basically I think they didn't get enough OEMs signed up and Glickenhaus and byKolles queried why independent teams were being frozen out - so it's still really a prototype series. Toyota might do a production run of 300 cars which I think is the minimum.
The LMH rules though have some very strict BOP measures. A minimum weight like most series, plus length, width, height. There's a strict power curve for the engine. Then downforce, drag, and aero-efficiency are regulated - which allows the geometric rules to be relaxed.
So compared to LMP1 the LMH are heavier, less aerodynamically efficient, and power limited. But not necessarily based on production models as originally intended.
