Scuderia Ferrari SF71H

[LM10]

Thought Ferrari was not going to bring updates to Bahrain, but a bigger update to China. I read that they wanted to minimize the damage in Bahrain with an unchanged car in comparison to Melbourne and then bring updates next week. Obviously it's not the case. Would have been strange anyway to not bring anything. It would be a lost time to not test new things and when needed do changes for the following race.

From what we've seen there are updates on the diffuser and bargeboard. A new floor is planned for China.

Even with this new diffuser having smaller ramp angle of centre section than what was seen in testing, looks to me like a bigger angle than on RB14 and W09 for example.





If they make the first one work at some point, wow...

Also, I don't think we should compare it too much with the one they ran near the end of the 2017 season. Seems to me like there was a lot more expansion in centre section, than in the outer ones. Just look at outside edges, looks to be making the inner vortex work much more than last year, since they are directing them more sideways than upwards (just like Merc and RB). It's harder to keep it attached and it also pulls more air from the middle part of diffuser towards it now (if main vortices are indeed stronger).

The diffuser edge has an outwash tunnel similar to the front wing.

No, they just looks around Or maybe they do both

It does appear as if Ferrari actually used this diffuser in Melbourne so not new.

It didn't. It was just tested for a short period of time during one of the FP.

Nope. Im on mobile now so I cant link, but on Motorsport.com Australian race pictures it is clearly visible Ferrari is running current diffuser.

It's been like that since launch on SF71-H. And this is also what Merc was doing from the start of 2017.

Good look on sidepod inlet and crash structure.

[Vanja #66]

Great shot, thanks!

Now that we see their cooling solution, it's not surprising that they've let it out in the open - it's very conventional, unlike last year. Here's hoping we'll see some different shapes of side pod leading edges around inlet, since it's not a part of the tub any more.

Last year was also "conventional" it was just that one shot with partially disassembled sidepod. On the pic (SF71H-above) is fully disassembled



remove the red part that is covering side impact structure and it's very similar

ICYI:
Since there were speculations about a new floor/diffuser that was delivered during FP1 here is a picture of the diffuser in FP2. Nothing new by the looks of it.
And I think Ferrari said that the delivered floor is just a spare.


Sry for the bad quality

Article from Italian webpage.

The Ferrari SF71H seen at the technical checks did not present major technical innovations compared to the victorious one in Australia. During the free practice in Melbourne, comparative tests were carried out with a version of the front wing very similar to that of last year. After analyzing the data the version of the wing brought to the track in Australia has been abandoned in the return to use the "classic" mounted on the SF71H since the day of the presentation. Wing that is easily recognizable because of the presence of a double blowing that the Italian team has inserted on the mainplane and for the upper flaps that are anchored to the large flow diverter positioned on the leading edge of the main profile.

In the rear area, on the other hand, the modification in the outside area of ​​the diffuser brought to the track in Australia was confirmed, which is different than the previous version due to the presence of a small transversal profile that joins the external part of the diffuser. This were the changes that both drivers also confirmed for the qualification and the race.

Compared to the Australian version, the Maranello team has made a small change to the central channel that, in the version seen today in the pits, seems to have a more squared shape compared to the previous version.

A solution that guarantees a better stability in the generated load, losing theoretically in expansion (to be evaluated, on the other hand, a possible slight increase in the rake angle).

Thank you for the article.

So, no new floor, no changes to the diffuser and also no changes on bargeboard-area (which on some pictures seemed so). They just switched to the frontwing which was mounted on the presentation and made a slight change to the central channel.
This also means that the new floor will come to China, as said before.

This quote from the Italian article describes the exact modification to the diffuser being discussed here, it does not say there were no changes:
