I see the topic got pretty active after official release of GR010, so here some of my points.

Slightly disappointed by this slightly simplified LMP1. It looks pretty cool because of that, but it's not a hypercar. I'll say it again, these rules are dumb.
I was expecting that lament about "expectations" and "reality" case, but I will agree in many cases rules are quite dumb and not bring what was supposed to be.

Think they have 5 jokers in the 5 year period?
Yes, there are allowed 5 changes to homologation document in 5 years, yet don't expect "new car each year".

Been looking closer. Really interesting rear end. The diffuser is angled quite severely towards the sides of the car which is where it's clearly fed from. Then ~500mm ahead of the rear tyre there's a sort of skirt to "seal" off the floor (influence tyre squirt) a bit ahead of the rear tyre. Can't tell much from the front but only looks like a single plane front wing(?) with really low front wishbones.
Diffuser is certainly fed from the sides of the floor as it is in general in prototype sportscars. However what you might miss about the floor (and any other aero device) is that every homologated car has to satisfy new set of aerodynamic criterias for safety reasons, beside getting into allowed working window. I can only tell that this point makes aero development more multi-dimensional than before.

The front end may be more of a diffuser now since they arent allowed to adjust its angle. The exposed front wishbones seem odd, when did they remove the requirement that they be covered when viewed from that angle?
You can choose which element you can adjust in terms of aero. It can be front wing, it can be rear wing, it can be anything else as long as there is only one element adjustable. In most cases obvious will be to have adjustable rear wing.
They changed covering wishbone requirement for LMH regulations.

But the aero surfacing, as borne out by the lower downforce & drag targets IIRC, definitely suggests less downforce generation than the LMP1 cars.
well... you can tell that by first set of LMH regulations, where aero numbers were actually there.

Meanwhile, Glickenhaus seem to feel a naturally aspirated V8 will provide sufficient efficiency despite the numerous turbocharged customer engines available - most curious.
Glickenhaus will use twin turbo V8, the only car which is supposed to have NA V8 is ByKolles, and obviously Alpine with their rebranded and adjusted Rebellion R13.

In general I think racing should be much better due to BoP and working windows ruleset, however from engineering point of view... I wouldn't say it's step back, but just step on the side... In the end they wanted to make cars more affordable to make with less budget spent to bring more teams/manufacturers there.

And about GR010... there are plenty of adopted/adjusted solutions from well-tested and reliable TS050.

Not an especially detailed comparison between the TS050 & GR010, but I found it a good general overview.

Just noticed there are holes on the trailing edge of the rear pontoons, just above the gurney flap. Wonder what they exhaust from?

About BOP, would it be possible to run a car more efficient, after a BOP has been set?

Sure, usually they call it sandbagging. Run like dirt when BOP is being established, suddenly find pace in hand when race day rolls around.

I’m not sure that they are holes, it looks more like reflection to me. However IF they are holes the shaping just prior to it would suggest it being an inlet rather than exhaust.
The more that I look, the more convinced I am that it is reflection...

It would be neat to see it compared to the previous TS050(?), it looks like a prototype rather than a hypercar.
If ‘hypercar’ regs result in nothing more than a re-named ‘prototype’, no wonder AM went cold on the idea!!
IMO the last batch of WEC cars (hybrid era) are some of the fugliest race cars ever! (Closely followed by the 1st gen Daytona Prototypes). ‘Sports cars’ should be nice to look at...
Just a new LMP1...

RBAT to help with hydrogen class of cars in a few years now. Didnt know it was going to he a spec chassis class.

Have watched most of this weekends 24h of Daytona. I was impressed, close racing for 24h and those Dpi’s are beautiful. Much exciting than looking at an LMP1 over a lap in front of the other 1, than to blow a turbo an be gone to the pits.

The car, dubbed the SCG 007, features a 3.5-liter twin-turbocharged V8 produced by French engine specialist Pipo Moteurs. It features a pair of heads derived from the engines used by World Rally Championship cars and includes an “artificial intelligence throttle” that keeps the turbochargers spooled regardless of throttle input, The Drive reports.
