For the topic of this thread, it does make me wonder how the current GTE teams would react to a GTish top prototype class. Would some of them step up and ignore their GTE programs or do a program in addition?

Very good question. I guess it depends of the cost, how free will the rules be and if they are going to apply some kind of BOP.
LMP1 just fell by the explosion of the costs and the same thing happened at the end of 90's, I have the feeling that the ACO will take its precautions this time.
if this GTish top prototype class happens, perhaps the most logical would be that the GTE transform into these GT1 or GTP rules and GTE-AM use GT3 cars.

Good way to ruin 2 classes! One of which has been pretty FRAKKING good for 15-ish years.

The idea would be to bring back the GTP or supercars spirit (Aston Martin Valkirie, La Ferrari, Mercedes AMG) like the GT1 in the late 90's.

Considering that a lmp2 can't cost more than about 500.000€
If for this GTP cars will be used lmp1/lmp2 regs. chassis, it couldn't be much more expensive, surely cheaper than an lmp1.
You can build any kind of car shape around that kind of carbon tub.
Considering that new gte cost is about 1mln €, don't think that GTP cars could be more expensive.

Example: take an lmp2 chassis, build around a bodywork looking like a LaFerrari. Fit inside the same road V12 6.2 (without hybrid stuff of course) and you get a new GTP.

I like the idea, these cars would be more beautiful than the current LMP1.
I wonder if the new Toyota hypercar mentioned in the Toyota LMP1 thread has to do with this change of ideology of the ACO so that these hypercars are the Top class.

Why would they do that? DPi is basically what that is. The car's themselves should be strong enough to race. They lower the weight/aero treatment further than GTE does and they'll be monster quick.

Those flights of the Corvette DPs occurred before the 4 holes of the body were placed in the part near to the wheels just like the LMP. When IMSA required the placement of these holes the cars did not fly any more and they did not have the fin.

That was the Old Folks Racing Riley and it had the holes.

As Matt said, it did have the holes. Also, just because one didn't fly, doesn't mean it wouldn't - it could mean it hasn't been under those circumstances.

Yes the fins are ugly. I personally find the holes uglier myself, but I think we all agree both are ugly. But they do work. We do have less flying cars than we used to. Yes, there are circumstances where they haven't worked, but in the last 7-8 years combined, that adds up less to 2008 alone.

The fins are ugly, but don't get your hopes up - it does help and they'll stay. It might as well be something we get used to.

I hope that somebody correct me if I am wrong but I have the sensation that the fin does not serve to avoid the flight only serves to stabilize it in case the flight occurs so that the car is going in a straight direction without starting to spin. I think only the holes are to avoid the flight.

It does both. https://www.carthrottle.com/post/how...omeback-to-f1/

http://www.motorsportmagazine.com/ar...-new-shark-fin

And it’s not there merely to keep the car straight. It works by offering an aero-obstacle once the car has yawed, or rotated, sideways beyond recovery, for whatever reason. Air rushing over the car side meets the fin and piles up against it, boosting pressure above the car side and cancelling the deadly lifting force.

Don't thank me! I tried to write it up, and it was like a 5 year old trying to explain how aerodynamics work I eventually gave up and Googled it.

Unfortunately, it does mean that we're probably stuck with the fins for a good while. They aren't pretty, but I don't see them going away, or the holes for that matter. Even if big GT concepts replaced LMPs.

For what it's worth, I don't find the current LMPs THAT ugly. I don't know why, I just don't. I prefer them to the open top with a single seat, and I really didn't like LMP675 style. I like the current LMPs. 2016 Audi R18 was ugly though.

The new Ferrari FXX K Evo has a small fin too.

I'm not an expert on such matters, but doesn't the extra 400kg of weight on a GT car mean it takes even more force to blow over compared to a LMP? Also, does the diffuser on the current generation of GTE cars increase or decrease the likely hood of a flip?

If those gets high enough it should increase the possibility of a blow over. At the very least it won't be helpful.
