“From f1-data analysis page”

The 'flexy-wing' clampdown is here: it will hurt several teams, and some more than others.

Making the front wing flex provides two benefits:

-Less drag on straights
-Aero balance (lower front downforce coefficient at high speed balance shifts towards understeer more stable at high speed)

-Several teams (McL, Mercedes, Ferrari, etc) stiffened their front wing to comply (notice McLaren's additional bracket)

-To my understanding, Mercedes' wing flexed the most, then McL, then Ferrari/RBR. @dr_obbs came to similar conclusions. This could make Mercedes slide further back, and allow Ferrari and RBR to catch up with McLaren.

Well we'll see tomorrow because everyone saying things and the only thing that will tell us anything is Laptime

It's clear that the TD compliant wing moves much less. The reference is the gap created between the wing and the brake duct inlet at top speed (left side). That gap is much bigger on the flexi-wing at top speed.
It doesn't turn.

Some questions were asked about the TD in the pre-race press conference which Lando attended.

Carlos claims it could be up to a 1 tenth swing in performance. It will change the balance of the cars but most teams should have re-balanced them in the simulator pre event:

‘Q: And what about the impact of the technical directive that the FIA is introducing this weekend? What has the team told you about the impact of that?

CS: Yeah, there's been obviously a lot of talk regarding this. I don't think it's going to affect teams and people as much as people think or as much as is being made about this change of regulation. It's still a front wing and still will be, just obviously run a bit stiffer and it will not flex as much as it did. I wouldn't expect more than one-tenth swing up or down through the field for each team depending on how much you were flexing or not.’

‘Q: But Carlos, do you think the car will be more difficult to balance as a result of this TD?

CS: Yeah, but I also think nowadays we have a lot of tools—mechanically and aerodynamically—to tune these cars. So even if it's going to be more of a challenge, we still have three practice sessions to see where the car is at in FP1 and take steps to fine-tune it and get it back to a decent place. You can imagine teams also in the simulator have been running endless laps just with a new wing. Nowadays, F1 teams are too well prepared, ion that sense, to be caught out by this kind of change.’

Lando again isn’t too concerned:

‘Q: Let’s bring it on to this weekend quickly. Are you concerned about the TD and how it might impact the MCL39?

LN: Nope. Not at all.

Q: What has the team told you about setting up the car? Will the aero balance shift to make it harder to drive?

LN: Like Carlos said, there are little tweaks here and there. But no, nothing that will change how we have to do anything.’

Well, that pretty much rules out the theory that they were already running a compliant wing.

In going to dare say that the drivers are still being a bit bullish over the negligible effects.
If it didn’t have a performance decrease, or upset balance, then they would continue to run the wing in the other FP sessions and the rest of the weekend.
That way you get more data on it rather than just 1 lap and removing it for your non-TD compliant wing
Mess with the Bull - you get the horns.

So now we have several drivers and teams saying it WILL impact both performance AND balance, making what Mclaren are saying a flat out cope/lie. They already have a somewhat tricky car in qualifying, anything that makes it even worse will already be a very negative impact, let alone the 1 tenth of lost time Sainz is mentioning.

Indeed they are.

If the Td compliant wing will make the cars harder to drive in general, then it can give an advantage to Red Bull. Because Verstappen can handle those tricky cars that others can't.

I think on the grid if everyone would have been given an equal car, Verstappen and Charles would come at the top. Followed by Hamilton and "peak" Alonso.

If the stiffer wings will mean higher drag, wouldn't that hurt Mclaren the most? Their car is already way too draggy, and they have poor top speed. Their baseline drag is already elevated, so adding more via stiffer wings amplifies the problem.

Red Bull new wing shape, with TD compliance:

I don't think the wing is a "new" shape. It looks like the old wing.

It doesn't turn.

Rob Marshall said this won’t affect the MCL39 months ago and he doesn’t strike me as someone who would be just saying that for the media or whatever, so I think it’s safe to just go with what the man says hah

Yes.

Peak Hamilton should be on par with VER and LEC or at least very close
