[LM24] Test Day 2021

[Ferrari333SP]

Sucks we have to wait two days before more on-track action

[GT6]

Well to me the most surprising thing was that the times are so close in all classes, obviously the race may be different but i hope that i will see close racing this week, and boy am i looking forward to it

[Mike E]

About the different performances of the 708 and 709:

“We did two very different jobs on the two cars, working on different topics. One car was working more on setup and the other was working more on control settings.

“This is the reason why we have had a difference of performance between the two cars.

“The No. 708 was working on setup. Now we have to merge everything together and see if we can find something between the output we did with one car, and the output we did with the other one.

“I can tell you that it’s been a very good testing day.”

Obviously running through their programme, as they did at every test day. The Toyotas put in horrendously quick average laptimes in the afternoon, laptimes in succession, for which nobody couly put an answer in the Hypercar class. I was veery impressed by their pace.

I merged the obvious United and United USA, but didn't bother with any other relationships.

Adam, thank you for all the data, nice work!

Jim has to boost the car sales somehow, nice try though

Yes, there were several good practice runs by Toyota.

Here is an average "stint" laptime. For the fastest 15 "stints" that were 7 laps or over. Actual there were only 15 times that a Hypercar did 7 laps or over. I needed to go down to 7 laps to have #709 in and also to get more than one Alpine.

Car	Make	Team	Stint length	Fast laps	Average
8	Toyota Gazoo Racing	Toyota	7	6	3:31.482
7	Toyota Gazoo Racing	Toyota	12	9	3:32.143
7	Toyota Gazoo Racing	Toyota	12	10	3:32.413
8	Toyota Gazoo Racing	Toyota	12	10	3:32.461
7	Toyota Gazoo Racing	Toyota	12	9	3:32.472
708	Glickenhaus Racing	Glickenhaus	9	6	3:33.145
8	Toyota Gazoo Racing	Toyota	13	8	3:33.991
8	Toyota Gazoo Racing	Toyota	7	6	3:34.254
708	Glickenhaus Racing	Glickenhaus	12	10	3:34.528
36	Alpine Elf Matmut	Alpine	8	5	3:34.931
7	Toyota Gazoo Racing	Toyota	7	5	3:35.693
708	Glickenhaus Racing	Glickenhaus	7	6	3:36.414
709	Glickenhaus Racing	Glickenhaus	7	6	3:36.655
7	Toyota Gazoo Racing	Toyota	7	6	3:36.731
36	Alpine Elf Matmut	Alpine	8	6	3:37.841

Stint length is the number of laps that car did in that run. Fast is the number of laps are the number of laps that went into the total. I have removed "slow" laps, as before these are any laps more than 10% slower than the fastest for that car on the day.

Fastest for each car is highlighted.

[Adam43]

Here is the same top 15 for LMP2.

Car	Make	Team	Stint length	Fast	Average
23	United Autosports	Oreca	11	7	3:35.305
30	Duqueine Team	Oreca	11	10	3:35.623
22	United Autosports USA	Oreca	11	9	3:36.007
31	Team WRT	Oreca	11	8	3:36.100
41	Team WRT	Oreca	7	5	3:36.314
22	United Autosports USA	Oreca	12	9	3:36.329
48	IDEC Sport	Oreca	8	6	3:36.494
34	Inter Europol Competition	Oreca	11	8	3:36.526
65	Panis Racing	Oreca	11	8	3:36.785
41	Team WRT	Oreca	8	5	3:36.869
31	Team WRT	Oreca	9	8	3:37.086
32	United Autosports	Oreca	10	9	3:37.188
34	Inter Europol Competition	Oreca	12	7	3:37.253
31	Team WRT	Oreca	11	8	3:37.352
82	Risi Competizione	Oreca	12	10	3:37.679

A better indication than those fast laps on the short stints.

A strong showing by United. A good pace advantage there for LMP2 and they appear 4 times in the list. They could still do with a decent qualifying to make that count early on.

WRT appear a lot too, but some of those runs were a little shorter.

There were 102 "stints" 7 laps or over.

Here is the #84 car in the innovation class:

Car	Make	Team	Stint length	Fast	Average
84	Association SRT41	Oreca	7	2	3:42.558
84	Association SRT41	Oreca	10	3	3:54.863
84	Association SRT41	Oreca	10	6	3:56.666

Got a couple of longish stints in, but one had quite a few slower laps. Presumably hit by SC/yellows.

[Adam43]

GTE Pro

Car	Make	Team	Stint length	Fast	Average
91	Porsche GT Team	Porsche	10	7	3:53.978
79	WeatherTech Racing	Porsche	13	11	3:54.390

52	AF Corse	Ferrari	7	6	3:58.272
92	Porsche GT Team	Porsche	8	3	3:58.537

There were 21 stints of 7laps or more.

Porsche and Corvette with a pace advantage over Ferrari?

And as these are long stints - does this mean no tyre deg. issues for Porsche here?

[Adam43]

GTE Am

80	Iron Lynx	Ferrari	7	3	3:58.426
57	Kessel Racing	Ferrari	9	8	3:58.426

94 "stints" were 7 laps or more.

Some of these stints are a little short, but I stuck to the arbitrary 7 laps minimum.

Making it 10 laps or more you get a slightly different picture, but Project 1 are still at the top and there are some teams that appear in both.

Some notes from test day from EI

https://www.endurance-info.com/auto/...a-journee-test

One i find interesting, is how fast the AM's are in LMP2. This can be so important to a cars overall place in the class but I don't really see this talked about a lot.

John Falb (G-Drive Racing) fastest of Am in LMP2: 3: 38.237

Thanks for the stats above Adam, it is going to be tight between the LMP2 and Hypercars all race long. Only a couple seconds slower on average stint lengths doesn't spread the field much.

LMP2s will be stint length limited though. But I agree it is going to be nip and tuck and if the P1s trip up then the P2s will be there to benefit.

That will be a big part for sure. I wonder what those numbers are going to be though?

We have to imagine Toyota having the longest stint length with Glick probably able to match. Alpine 1 less lap, and then P2, will they be near the Alpine or even a lap shorter?

[TF110]

Can't wait to see how the times develop through the week as the track does the same.

Does anyone have an idea where I can get the driver ratings (Bronze to Platinum)?
I have a non-editable pdf from test day: http://fiawec.alkamelsystems.com/Res...%20Testday.pdf

and this helpful list https://driverscategorisation.fia.com/public/drivers

But niether are exportable in an easily useable format. The latter has annoying pictures instead of words like "Gold".

[Ferrari333SP]

Weather is looking pretty great the whole weekend too, so hopefully the winners can get into the 380's or higher in total laps

The Am competitions are going to be decided by the performance of the Ams - there is a big difference in lap times, at least from the test day.

LMP2 Am: Below is the fastest lap time from each of the Bronze drivers at the test day

Driver	Car#	Team	Car	Laps	Time	Gap
John FALB	25	G-Drive Racing	Aurus	30	3:38.237	0

Dwight MERRIMAN	17	IDEC Sport	Oreca	10	3:56.915	18.678

At least most got a decent number of laps running at the test day.

BTW I didn't find the data, but did take apart the webpage the data was on.

[Adam43]

There is a similar range in GTE-Am over the bronze drivers. Although there are a bunch near the top that are close to each other. Going to be a good race.

There are some that didn't get that many laps and maybe that hurt them.

[joeb]

Thanks, this is exactly the type of data I was looking for!

This is one reason that I tend to find the amateurs more interesting that the professionals.


I'm quite probably in a minority on that though

[Adam43]

There will be some good racing that is for sure.

Next up is a distribution of maximum speeds (from the ACO's timing). I hope this chart is clear. It shows two things.

1. The bars are the distribution of maximum speeds and each class. The number of cars that registered the specific speed as their top speed is shown against the right hand axis. There were three cars that registered 331.8 and two with 329.8 km/h.

If you want just a list of these speeds, check out the official timing page: http://fiawec.alkamelsystems.com/Res...Test%20Day.PDF

Interestingly the measurement it quite discrete. It hints it is accurate to the nearest 0.1km/h, but it isn't. At the highest speeds it has 1km/h intervals in the data.

2. The lines represent a distribution of the speeds seen in a class across all laps completed and all competitors. This could be viewed as a likelihood of that speed on each lap.

As you see the distribution stops at the highest recorded speed in that class.

I forgot to mention. The data shows all at the test, even if they aren’t down to do the race.

Those as noted in this DSC article. http://www.dailysportscar.com/2021/0...and-notes.html

Very appreciated, big thank you!
