Regarding the regulations and cars allowed. Old = current. New = 2016 regulations

2016:
GTE-Pro - Old and New
GTE-Am - Old

2017:
GTE-Pro - New
GTE-Am - Old and New

2018:
GTE-Pro - New
GTE-Am - New

Am cars will continue with the current spec for at least 2016.

Yes. The maths involved in figuring that though are a bit....uhm....stupid.

It's a theoretical performance window, and with BoP being what it is for the WEC, sandbagging, or detuning is really discouraged through a natural process, instead of being encouraged in TUSC.

Personally I'd like to see the BoP be initiated for the next year after the test and season has concluded, versus after LeMans.

Eh, are you mixing up P1 EoT and GTE BoP?

Can someone in the know explain how the removable seats work? Are they still bolted in but just need to be small enough to fit through the roof hatch, or is there some quick release seat mounting involved?

I've always thought the safest way to mount the seats was to bolt them at the bottom and the seat back to the rollcage, and then have the belts passing through the seats, but actually bolted to the rollcage.

Yes, I agree that the seat mounting be isolated to the cage and the belts also mounted to it.
SWAG.... a solid seat bucket, that a second solid insert with quick releases goes into and the belts through both. That would also facilitate individual inserts being used for driver changes. Hatch size?

Yes the cars will be required to have a roof hatch next year to facilitate the removal of the driver and seat.

Yes,..... I was quizzical on the size of the hatches as they have to also facilitate a part of the seat coming through them. Will it be just the/a back panel that acts like a back board for extracting the driver? Or a whole seat of sorts? Getting the driver out in a full seat with them in a seated position it seems the hatch would have to be quite large and possibly present a weak spot/zone in the roof above the driver.

Take a look at the hatch size on the FordGT

And a mysterious Porsche

and from the ACO Powerpoint

Ahh....gotcha! Yeah, I wouldn't want a big open spot over my head either, but I guess in a flip the bodywork is likely to come off anyway. I know in F1, for example, the seats just have loops attached to them so they can remove the driver and entire seat out the top, but those seats are pretty small and basically are just padding between the driver and the tub, so I see your point. I would think the whole seat would have to come out though, as one of the points of the whole seat/hatch rule would be to keep the driver in the same position without moving him in case of a back injury.

Mike E · 2 Sep 2015, 10:15 (Ref:3570703)

Thinking out loud here... If there is enough concern about the driver that he/she has to be removed with the seat through the roof then the rescue crew would probably just cut the roof if they needed better access. The hatch rule at least means no roll cage tubes directly above the driver.

MoMedic9019 · 2 Sep 2015, 13:45 (Ref:3570752)

We would just cut the cage. It would be significantly faster.

This is for routine removal if the driver cannot get out on his own, or needs to be removed quickly(car on fire, on its side, or doors unusable)

YorkshireLad · 3 Sep 2015, 08:33 (Ref:3570969)

Are the media invited to the ladoux test?

Brake dust · 3 Sep 2015, 12:21 (Ref:3571017)

Do the new regs allow for carbon fiber suspension? Keep thinking that Porsche will utilize the 918 (without hybid) and adding a turbo to the v-8 to race in 2017.

MitchZ06 · 3 Sep 2015, 12:22 (Ref:3571018)

Not if I remember correctly, also no point to use carbon suspension in a GT car. Porsche won't race the 918 sorry, 960 is the number combination you need.

**joeb** · 3 Sep 2015, 13:37 (Ref:3571031)

Perhaps he meant the 918 could be the basis for the new mid engined car.

Yes, the 960 which would be derived from the 918 sans hybrid. Porsche is well known for exploiting all of its product development. The CGT engine was originally developed for F1 then LMP1 before ending up in the CGT. Was wondering how much would have to change to meet the new 2016 GT regs?

Didn't the 918 engine start its life as a P2 engine?

Indeed! (P2 engine used as a basis)

According to this article, Fehan states it is for the insertion of a backboard and ease of access to the driver, not to extricate the driver w/ or without a seat through it.
