Flexiwings 2025

[FittingMechanics]

Any footage of rear wings that people seen?

I did a quick watch on F1TV - nothing seemed too obvious. Norris and Verstappen both have rear views for multiple laps.

The mini-DRS is probably going to be inconsequential, the flexing that can be seen in the video above however is not. The entire thing is built to flex, down to the beam wing. Look at the gap between the diffuser and beam wing. We are back to the levels we had 4-5 years ago.

Quite telling the rear wings on these McLaren clips.

Sure stuff like that got ruled out years ago. Why aren’t the FIA policing the dots properly on the rear wings

Oh, so now it's easy to understand how they could get away with the huge beamwing...

I'd be very surprised if this whole wing flexing backwards isn't banned. FIA have already set a precedent when it comes to this exact issue. We saw the Mercedes wing also flexing just as much during testing.

Here is the RB21 for comparison, looks a lot more stable.

People here are miss-interpreting ...

But if you don't trust my words then please, read the actual FIA wording on the new stricter ruling :

Update to Article 3.15.17: When 75kg of load is applied to the rear wing, the slot gap must not vary by more than 0.5mm instead of 2mm (with a temporary 0.25mm tolerance for Shanghai).

It's not about the flexing of the rear wing assembly, it's about the width of the gap that is opened up between the mainplane and the drs flap as a "side-effect" of that flex. They already made the rule for the former stricter before Australia. Also if you want to call this gap-opening a mini DRS as well, then go ahead, but it's important to make the distinction with the mini DRS of last year, because they're completely different in principle even if they ultimately try to achieve the same thing.

Finally, there will be some level of flex to the wing on all teams, as we saw with Mercedes in testing (and I am sure it's visible on every single team too) :



This will continue to be like this beyond Shanghai too, because it's not what the new TD is targeting.

No, it's really not visible in every single team, it's mostly limited to two. Just look at the RB wing during the race, just before your post, it's barely lowers when compared.

Sigh ...

For a technical forum, you would expect people to put their personal bias aside when discussing technical details. If you want to have a proper discussion, at least provide some proof for your statements. If you can't provide proof, you're just spreading miss-information.

Just because it's less at some, doesn't mean it's not visible in every single team.

Here is your beloved Red Bull in Australia :



And that's on 270-280 kmh, because there is currently no footage of RedBull's rear wing at the end of the straights.

Anyone has a video of MB? We saw from them the only video in testing where the whole rear assembly was bending not millimeters but centimeters.

The load test is not about the bending of the whole assembly! All of them have the squatting.

You just proved my point, that wing barely moves when compared to Mclaren and Mercedes (haven't seen Ferrari yet). You just need to look at it mid corner, even, almost zero elasticity and sideways movement, compared to the other two.

None from Mercedes and Ferrari in Australia sa far as I know.

I am sorry, weren't these your words? You're the one who also made it personal with the "look before you post", because you didn't like someone's comment as it doesn't fit your narrative.

Some have it less, some have it more, but it is visible on all of them, because that's how a rear wing made out of carbon fiber will act under stress. Also, it's not even the point of the new TD. If RedBull has it less, it's an intentional design choice, or they don't possess the manufacturing capabilities to make it more flexible, because others clearly have shown it's possible to have a more flexible rear wing and still pass the tests.

To me the reaction of FIA is quite strong for something that doesn't seem to be at all visible in the footage we have available (McLaren and Red Bull in Australia, Mercedes in Bahrain). I think that there has to be a more visible, obvious "mini DRS" happening for FIA to institute an immediate clampdown in 7 days.

Is there a footage of Ferrari in Bahrain or in Australia? Is it possible that Ferrari had a "mini DRS" wing that FIA told them Saturday morning that it is not allowed?

Flexing of whole wing assembly is not what is being test here, they are measuring the deflection between parts of the wing so deflection of the whole wing doesn't show up on this.
