I haven't spotted any obvious changes yet

either we will see them tomorrow or its more mechanical hidden changes.... or it could be another smoke and mirrors case where there are no changes at all...

They've brought updates to every race according to the team, but obviously they only need to report what is external and visible.

With Toto saying they were bringing performance upgrades here and Allison saying all the way back in Imola free practice that they were bringing a big upgrade package before the summer break id be surprised if this was it or that they brought nothing at all

That cooling duct on the nose section is enormous.



Not all is as Mercedes wants people to think...

[Formula 1 fan]

Is it true that Mercedes will not bring any upgrades for the Hungarian race?

You literally ask this 3 times every weekend lol

There’s an upgrade 1 post above. We won’t know more until tomorrow.

Looks like the rear wing tips are designed to stall above a certain speed. It is aided by the cranked metal bit in front of it. That metal guide must be a big blunt object as speed goes up thereby stalling behind it and stalling the rear wing tip.

Could you explain further how this would be achieved. Their drs efficiency has improved as shown by the data so I'd be interested in the method of stalling the wing you mentioned

[PlatinumZealot]

So to be clear i said stalling the wing tips.. Not the entire wing.

Apologies typo on my part. Would be interested in what those bits are doing to the stall the wing tips though?

(This reply sounds so sarcastic reading it but I'm genuinely interested)

[PlatinumZealot]

Doesn't need much explanation actually. The angle of incidence of the metal bits is set very steeply close to the point of stall.. Except not in a longtidinal plane but a rotated plane... After certain speed it simply stalls..

You can see that the chrod is almost tranferse so a low pressure pocket. (F1 wings have high aspect ratio so they stall at high speed) There is flow detachment from it... And the pressure recovery reduces the drag under the wing tips behind it.


Someone can test it in CFD.. But this is my intuition on the shape of it.

Well looks like Xavi was wrong
