Would be cool to start working on 2026 cars next year and then in 2026 see how many F1 teams steal from you guys, wouldn't it?
Sure, I agree

On another note, do you know when we should expect the reports?
I think, they went out on Thursday.
Also, the Challenge page is now updted with the results:
https://mantiumchallenge.com/results-mvrc-monaco-2024/
But, just to make sure, you guys see it, here are the scrutineering results:

Busor Racing:
  • 2.3
  • 11.4
  • 12.2.1
CAEdevice:
  • 12.2.1
F.E.S.T.:
  • 9.1
  • 11.4
MaxTaylor:
  • 2.4
Variante:
  • 6.1.1
The repeated rules violation by F.E.S.T. and Variante, result in a penalty for both teams.

One to ruminate on for a while.

Things that shock me:

1) How flat the floor is
2) How limited the outer floor is in thickness and the plan suggests slots are going to be limited.
3) How raised bottom of the diffuser appears to be
4) No floor fences at all (other than the mandated in-washers)
5) No beam wing
6) Rear wing end plates are back
Nice spots.
7) rear wing is far back from the diffuser

Can you share the source of those geometry boxes?

It was just a picture the FIA shared as far as I know

They're going back to the early 2000s :o
All these rule changes over the years to facilitate overtaking just to go back to the good old days...

Those in-washers are very unusual for F1. But they remind me of the inwashing strategy I used to adopt on my old cars. I wouldn't mind having another go at them.

By the way, we're missing the CFD images.

Yeah, I only run "MVRC template" for the last few years now. By results this year have been within 0.5% error CLA of the official. I'm impressed y'all do as well as you do with the fast!
Unrelated to this but could I ask you to clarify a few things with the current lap sim setup Max?

Firstly, I remember asking before but a) can't remember what you answered and b) want to double check. How is the lap sim applying a DRS drag offset? I think you said it was a flat Cd offset that was the same for every car?

Secondly, how are we feeling about the interpolation on the website based lap time estimator? I know you made some adjustments but again I don't recall what limits you raised the interpolation to.

The DRS question is particularly interesting for the sake of the next two races and what drag numbers I try to achieve.

Cheers.

No DRS effects are being used for this year or last year.

I didn't actually end up changing anything as I ran out of time over the winter, so same as last year. Looking at the data for the first 2 races, the error does increase as you get higher CLs but for most teams it's around 1% laptime. Just a little extra challenge for the guys at the top :)
