[WEC] New rules. New manufacturers. The 2021 and beyond positivity thread!

[RL17]

The main fins are still there (incl Peugeot) but smaller than previous LMP1 type regs I assume as these made all the profiles virtually the same for back half - haven't F1 fins also reduced from a few years back?

Ferrari seems to have lots of small fins/deflectors for maintaining downforce overvarious surfaces in yawing movements.

It happens to do that but was not the intent when added to the regs

Hypercars are about 200kg heavier than LMP1s so they might be less inclined to flip even with smaller fins

Probably just as well considering we've seen a few prototypes flip over the years.

If it’s a requirement, why doesn’t the Peugeot have an engine cover fin?

It isn't a requirement to have a fin, it is a requirement to have aero that makes a flip while moving sideways less likely. So they must have addressed the issue another way.

Understood, although how is that regulated or enforced as a rule? Is it wind tunnel tests or something else?

I have absolutely no idea, but I would be interested to know as well.

There are criteria that has to be met in CFD. For various yaw angles and ride heights the car has to be better than a reference criteria. For Toyota they considered getting rid of the fin, but it was so good at achieving the aim that they still had one. I guess they just thought we have a good efficient solution, why waste time. There are actual things we can make better.

There was a good article of how the process works in Racecar engineering last year in the early Hypercar days. I think it was the one about the Toyota, but there were a lot of Hypercar articles around the same time. I’ll see if I can find it later…

It was the Toyota article.

Thanks Mr43, that all makes sense. And in the grand scheme of things, I'm guessing there is no incentive for teams to try and cheat this process. I mean nobody wants their car to flip!

[Sodemo]

Have NA V10s and V12s been effectively regulated out of feasibility with this current ruleset?

I actually would like someone to try and take a road car into the HyperCar class. Manufacturers make claims about road cars being able to lap the Nürburgring in so many minutes but it would be nice to see them prove their stuff against real competition!

[Aysedasi]

The Valkyrie should be there. I know from a very close family member just how amazing the car looks and sounds. If we saw it out on track we'd all be drooling - both at the looks and the incredible noise it makes.....

[Mike E]

The de Tomaso sounds incredible. Hugo de Sadeleer doing the driving here.

Terrific stuff! Quite novel of de Tomaso to use a toilet roll holder as a gearstick surround though.....

I'd imagine it makes quite the noise!

That sound would be a welcome note of freshness to the grid!

I love that sound, I love this car!!!
A V12 is more attractive to a boutique manufacturer than a V6 Turbo.
They are not going to win, they are going to participate and with that sound the car will be the most loved by everybody.

Another 'extravaganza' creation joins the brigade: https://www.motor1.com/news/622815/7...ace-car-monza/

Track special only for now, the few planned to be made can go play with the Valkyries and such.

Oh it really does! I have some snippets of video which I'd love to post - but I can't......

There should be a series for all of these track only cars to compete against each other!

[RL17]

Great sounds - possibly some would have been more of a true 'Hypercar' than LMP1.5, but can't complain with bigger fields now expected.

Do think about the Red Bull/AMR missed opportunities, especially with a few reminders on United Autosports 22.

[Adam43]

Good point, but for me:

Red Bull/AMR. Care factor: Nil.

[S griffin]

I doubt either RBR or AMR are interested in this. Their soul focus is F1
