[WEC] WEC 2021 season

[WyldStallion]

Forgive me if I don't like the wierd design templates of the car numbers for the WEC this year...in fact I hate them. Project1 #46 is the wierdest one yet.

If they got rid of the whole numbering system that was used previously then why are not the Corvettes '3' and '4' and why not are the Porsches '911' and '912'? That's less of a big deal.

Maybe its me. I always have liked structure perhaps

[Adam43]

As it’s the choice of the team we’ll probably see variety. Some we’ll like some we won’t.

I suppose we could have boring uniformity instead.

Have some concerns about the stint energy value, at example R13 max overall stint energy is 920MJ, 1L of E10 petrol has an energetic density of 30.9MJ/L, guess it's quite unrealistic R13 could refuel only about 30L a stint...



also because in 2019 silverstone 4H, eot gave to toyota 60MJ/lap as fuel max energy value, and according to alkamel data, toyotas were able to run 23 laps a stint at their best, basically 60x23 = 1380MJ for the overall stint.
Taken for granted that gibson V8 is however less efficient than TS050 V6, an overall 920MJ a stint should mean R13 having really shorter stints. Same for toyota that got 964MJ a stint and in proportion will need to burn more fuel when ERS boost if off due the extra power to produce.

Maybe it is a limitation on energy produced by the engine?
Not the energy that's in the fuel?
I guess they would have a sensor that would measure the power output in very short time intervals and at the end of every stint calculate 'actual' energy used.

don't know, it doesn't make much sense also because power curve is set by bop, toyota drivers always said that they won't need to lift and coast anymore, so is expected they would push all the time and no more fuel saving, unfortunately this implies the question about how many kg or lt of fuel they will be allowed to have in fuel tank...

So the Alpine is running at 2020 LMP2 weight and power.

Performance drop somewhat confirmed by DSC:

"Paddock Sources confirmed to DSC today that, in addition to the test we reported on at Paul Ricard with a Toyota GR010 testing back-to-back with a full 2021 spec LMP2 (the Racing Team Nederland car) there was another test, prior to the ELMS ‘Prologue’ test at Barcelona which saw the Alpine A480 ‘Hypercar’ tested at the same time as at least one 2020 spec LMP2 (with 2020 power and weight), drivers unknown, as was the spec to which the Alpine was running – The LMP2 car was quicker by well over a second per lap."

That type of nonsense everyone can see in timing sheets underlines perfectly the idea: that's what you get when think everything can be done with "smart" bopping instead of firm tech regulations. This crap is not even a joke anymore. It's a symptom of a decease.

[canaglia]

Has something happened to #7?
I see it just scored few laps both now and on morning.
I won't be surprised if toyota and rebelpine will be just 1 seconds faster than detuned lmp2 during qualifying

Relax, its better than the predictableness of the last few years. Will be fun to follow for sure.

It will be interesting to see if the Alpine can match the P2 times from last season at Spa. I think there were some times in the low 2:02's or high 2:01's for LMP2 last season in qualifying. The same LMP2 car is now 2.5 to 3 seconds slower.

edit: also should note the Rebellion was on pole here last season with a 1:59.

DSC's summary of the afternoon session has some interesting points on pace.

Alpine again the faster of the two Hypercars that circulated, a 2:05.230 the best time from the 930 kilo, 600 bhp grandfathered LMP1 against the fastest of the 950 kilo, 530 bhp LMP2s, both running of course on low drag, low downforce aero packages.

Right now, the lighter, more-powerful P1 version is slower than the heavier, lower-powered P2 version. So what is going on? are the "hypercar" teams still learning their cars? Are they not willing to show their hands right now? Are the new rear-wheeled drive P1 tires requiring something on the Alpine that isn't there yet?

[Mike E]

Very good that the Porsches have switched back to the rear exit exhaust.

[helgi]

I have a single question only. Is it the first time ever (in dry conditions) when higher class is slower than lower one in any type of racing ever?

Examples cited include:

Strakka Racing Make History With Hungaroring Win

1995 24 Hours of Le Mans

2007-2008 ALMS, particularly Penske racing in LMP2.

[TF110]

I knew this would happen and Im glad its happening at the prologue so the aco/fia can see the mess theyve created with their current bop. Just imagine when success handicaps come into play.

[Mike E]

There are no success handicaps in Hypercar. BoP has replaced them.
The hypercars will be quicker tomorrow or the next day.

Maybe I missed that. Bop taking its place imo doesnt seem any better. I think its premature to say hypercar will be slower, but itll need drastic improvement because lmp2 isnt sitting still either. With the lm aero their top speed is tough to overcome as well.

[cavalo_mORTO]

There's no way the Alpine-Rebellion is slower than the ORECAS, when it has more power, better aero and it is lighter.
How can it be slower in S2? It makes no sense.

[seanyb505]

Yeah it definitely feels sandbagging shenanigans. I know there's a ton of aspects I'll never know or overlook, but I'd be real interested in either hypercar team's explanation of pace.

What weight and power were they both running?

[cavalo_mORTO]

Team WRT’s Oreca sat third at the session end with the #36 Alpine again the faster of the two Hypercars that circulated, a 2:05.230 the best time from the 930 kilo, 600 bhp grandfathered LMP1 against the fastest of the 950 kilo, 530 bhp LMP2s, both running of course on low drag, low downforce aero packages.
