Grand Touring Prototype... not too bad, and has a connection to the past when they had multiple chassis and engines from many manufacturers.
Not to mention that these will be running in both series.

Couldn't think of a better marque to first test it. If it's a trouble free run, that's a good start

Thanks for posting this. Lots to digest in there! I just skimmed through and looked at a few things. Saw that the engine cover fin is compulsory. Not sure if I knew that for lmdh. But they also say it is located on the engine cover, what if you had a front engine car?

6.4.6 At least one proximity sensor is mandatory to forbid the start of the ICE or any powering electric motor while the coupling is connected to the car.

Guess we're going back to the engine off refueling? Wonder if they'll expand that to other classes as well?

And for a certain member here who loves the GTs with the fabric tow eyes

Gave a quick eye, maybe I'll read it better some time later in future but it seems most of undercar aero design is basically mandatory/spec. Same kind of torque/power curve used for LMH and strange managment of hybrid boost, 30KW only for LM and daytona, 50KW for other circuits. Mandatory 7 speeds gearbox.

I'm sure once we get a non camo look we will notice some differences.

possibly some different ducting on the rear fenders and a different splitter shape.

Well, now that we've seen both the Acura and cadillac GTPs (LMDh), this should have us "all a twitter" for the rest of them(BMW, Porsche, Lamborghini, et al).

In an article on Road and Track about the new Caddy engine they had this info on engine regulations that I hadn't seen before:

Quote:
Regulations for LMDh engines are fairly open. They don't need to be production based, and as long as they fit within specified dimensions, don't rev beyond 10,000 rpm, and exceed 110 decibels in noise testing, they're good to go. Power at the rear axle is limited to between 644 and 697 hp depending on Balance of Performance, and manufacturers can decide how much of that comes from the ICE and how much of it is provided by the hybrid system shared among all LMDh cars.

Any idea how loud the cars are currently? is that 110 decibels similar or a reduction?
