WEC LMP Future Regulations (was Le Mans EVO rules - now hypercar rules) - Page 220

"A car that is restricted can possibly beat a car that's also restricted" is a completely pointless discussion. Just throwing that out there. Based on the current rules, the Cadillac DPi is nowhere near the speed of even the old Rebellion R-One. And that's just fine, because it isn't meant to be.

At all. Others come close(Aston Martin's V12 springs to mind, for instance), but in this era of fuel flow restriction I think the LT4 is the only road car engine that can produce the necessary power within the ACO's fuel consumption goals.

What’s so special about it (and also that old Aston engine)?

It's big and American (and British)?

I really don't know either, even if it is a very proven engine.

TF110 may jest about it, but he's right. I seriously don't know either. I only know that everything I've seen points towards the conclusion I come to. Even amongst a line of engines that is rapidly becoming legendary, the LT4 stands out as a particularly capable unit.

And I hope it's not the apex of the LS line.

The new Aston Martin Valkyrie AMR Pro should be the model to follow for the future 2020-21 rules.
It looks really incredible !!!
I want this style of cars for LMP1.

That looks quite good, but i didn't understand if there is an actual car at this point or if there are just drawings?

The car is in the Aston Martin stand in Geneva now, here is some photos.

Put usable headlights and mirrors, a plank, sloped floor, cheese wedges, anhedral splitter, proper fin, fender holes, and LMP spec roll over strucutre on it like you'd need to have an actual safe race car and there won't be much there for you to be wanting over what we have. Pretty much just a Mazda without legality panels, actually.

Yes, it is true the car looks incredible, you can see the hand of Newey in the great aerodynamic development that this car has, and also of course it has a V12 aspirated that makes it perfect!

TF110 · 7 Mar 2018, 05:13 (Ref:3806490)

I like it but I think the chance of it racing is slim to none. It definitely doesn't fit in any series. It'd be cool to see a lmp1 version but the wild aero would be lost.

So I missed that the Rebellion R13 was unveiled at the tail end of our recent debate regarding the viability of DPi in LMP1-L(I don't care that LMP1-L doesn't specifically exist anymore, it's easier than typing LMP1 nonhybrid and everyone still knows what I mean).

And I have to say...If Oreca and Rebellion hadn't been very clear that it's a whole new car and tub, I'd just assume they threw a new engine in the back of an 07. There's literally nothing obviously different.

Type it twenty more times and it’ll end up being more efficient. Assuming you don’t have to respond to some idiot asking you why you did it or being silly about it.

Aside from:
-The splitter
-Dive planes
-Rear brake ducts now on top of the side pod
-New shape to the rear wheel pontoons
-Exhaust now on the rear deck, which also neccessitated a change to the bodywork just in front of the rear wheels
-New wing endplates.

Well apart from the obvious, there's nothing obvious!

None of those things have changed as much as you imply - all but one of them are SMALL details, not obvious ones. The majority of people wouldn't notice even if you put them side-by-side. The most obvious difference are the dive planes and the rear wheel "pontoons", and nobody's going to consider the diveplanes as an indicator of a major difference. That leaves only one "obvious" difference, and even it doesn't stand out at first glance.

So, no, the differences AREN'T obvious, and the point still stands: It looks like an upgraded 07, not a completely new car.

Ooh, ooh; don't forget the headlights!

The R13 is based on an LMP1 car to start with, that's like pointing out the LMP2 Zyteks were similar to the LMP1s when it started as a 675. None of the other LMP2 cars were designed with the lower weight limit in mind, or anything else.

I'm mostly taking a jab at how when it comes to aero, everyone was talking like the LMP1s had to be so drastically different that you couldn't use an LMP2 car as a base even if you could get the weight down. (which I'm sure companies like Dallara, Oreca, and Onroak could if they needed to) The R13 certainly seems to torpedo that idea.

Granted, we've not yet seen it race so for all we know it could be an utter failure.

Ford has continued its push for a common set of global prototype regulations that would allow the American manufacturer to step up to the top levels of both the FIA World Endurance Championship and IMSA WeatherTech SportsCar Championship.

These guys might be a big key in IMSA accepting hybrid. They're balancing non-hybrid and hybrid in lmp1 this year, lets see how it goes. If it turns out ok there's no reason IMSA should say no to them.

But Ford alone isn't enough if GM and the other rebranding-OEMs insist on fielding spec cars or they'll bail out. Plus the former Grand-Am teams have a lot of bargaining power, anytime I think of budgets related to North America I see the red face of Wayne Taylor banging fist to the table and screaming "I'm not spending a penny more!"
