McLaren MCL39

Huge difference

So basically, they were already compliant with the TD?

Judging by this tweet I don't think that's what he was saying.

Now on F1TV live stream Alex Brundell, presenting McLaren FW said that he spoke with Rob Marshall and the outcome is like this:
AB: What changes did you do to the FW?
RM: We added one hook to the top flap. No material changes on FW.
AB: So how you mitigate the loss?
RM: What loss?

Based on the images they have made more changes than that. It's highlighted below.

(1) Different carbon weave directionality where the flap attaches to nosecone
(2) Additional flap strut
(3) modified angle adjuster bracket.

What's a modified adjuster bracket going to do?

It affects the rigidity of the flap assembly. The old design has a "curved" strut attached to the adjustment knob in order to allow the flap to flex more. The new design has a "straight" strut which makes the assembly more rigid.

Vanja #66 has highlighted that in green in the image.

Is there any chance you got higher resolution?

He was being sarcastic about the "huge difference".

You can find posts about RedBull and Ferrari and how they are exhibiting similar levels of flex as pre TD as well.

These might be better:

This is the curved strut holding the adjuster mechanisms on the flexi-wing (ignore the red circle, follow the red arrow):



This is the "straight" strut on the new (stiffer) wing.




They reverted back to the bracket design that that they had before Miami 2024.

Not my interpretation but I guess the man himself will have to set the record straight

So it's the 2024 strut and an extra hook.

That aint a new wing.

I thought the same as you, but felt it was looking at it in isolation. The performance difference can only be looked at relative to other cars.

Point made previously was that we aren't doing much more than anyone else although Vanja seems to be suggesting that what was really being said by the team (I guess) was that tightening the flex would make no performance difference at all. I'm not sure it was really meant this way, just that it would make no relative performance difference.

Clearly the wing flexes less, but relative to others I can't see much in it. Is this others assessment also?

[SilviuAgo]

Is interesting how anyone is talking about Front Wings as nothing else matters
Meanwhile, for those who wants a little brake from the subject, Oscars MCL39 rear, with some flow vis. Oscar run the higher downforce RW compared to Lando.
Few minutes to FP2 and see if they will switch the approach or both cars will use same RW configuration.



And a comparison between the 2 RW configurations:

I'm not commenting on the relative change to others. And I'm certainly not claiming it's a "huge difference". I'm just stating the obvious, the wing has changed in terms of flex, which indicates it wasn't TD compliant before as some suggested. That was also my interpretation of Vanja's tweet where he sarcastically states that it was "always compliant".

Yeah maybe I missunderstood. It's because I read the order of tweets from the first one, to the second and I assumed his sarcasm was linked to the first.

But considering that there is actually some difference in the amount of flex, I suppose the sarcasm was only related to the second post.

Ahhh I read that sarcasm as directed towards the team and Stella for the reasons I outlined...

For comparison also Lando's car rear config.

Both cars on lower downforce for fp2. Maybe seeking to achieve a better balance
