2025 Haas F1 Team

Sorry you are correct, I should have said Haas has also updates besides their Livery...

[SeriouslyBored]

i've always supported haas and i feel like they have potential this year, depending on how ferrari shapes up. previously in the past most haas performance has been similar to ferrari performance on a lower level. like for example 2020&21 where both teams were at the bottom of their respective "packs" and 24 where they were very competitive just as the Ferrari would challenge for wins the haas was in the points etc. depending on the issues these seem to be impacting both teams with similar areas involving ride height and suspension.

Some old and some new about Komatsu :

First try at floor updates for Japan :

Mostly similar things as the above article, but a little more detail.

The implication that they would produce the updates based on theory alone and then test them in the wind tunnel/CFD afterwards seems crazy but I guess that speaks to how desperate they might have felt in Australia.

Also:
“If it works, Komatsu reckoned the performance could be even stronger than in China, where Esteban Ocon and Ollie Bearman finished seventh and 10th on the road then got promoted two places each by Ferrari's double disqualification.”

It seems like Haas seem to think this car has extremely high potential if that is the case. I wonder, because we also hear from Ferrari that their car has “potential” or “has yet to show their true pace,” if there is a common problem. This could be fundamental issues like wind tunnel correlation or shared components like the rear suspension. I’m speculating more than anything but would not be surprised to see that be the case.

This can't be an entirely new design, surely? It's got to be some kind of "cut and paste" job with a section from an older floor

[Mostlyeels]

It's hard to tell: they just say they're testing the parts in the wind tunnel concurrently with producing and shipping them to Japan. Reading between the lines a bit, if it was a cut and paste job from an older floor, would they not just take the older floor as-is, and save themselves a lot of time physically building a new one?

From the Autosport article:

Komatsu explained more about the 'risks' involved in developing the floor update, explaining that it was a case of producing the revised floor parts quickly and then retrospectively testing it in the wind tunnel while it was being shipped to Japan.
He said that the ad-hoc test in the wind tunnel suggested that Haas was moving in the right direction, but reiterated that he would remain unsure of the impact of the floor changes until the car actually takes to the track.

Progress was made on day one:

The new floor might just need a particular section from an older version that the designers believe would have a positive effect.

They possibly didn't test the update as a whole yet because they've just recently discovered the solution.

I doubt it is as simple as them taking an older floor or even floor section. Although still very unlikely I would find it more believable if they brought an entirely new floor. As it is so early in the season I don't think there is an "older" specification of floor for the 2025 car; they have had the same one since testing. And given the chassis has changed plus the new Ferrari gearbox for 2025 I don't think a 2024 floor would even fit correctly.

Most likely is that they have bonded some kind of new element or section to the existing floor, most likely somewhere around the start of the diffuser or mouse hole area. Maybe xavi gasquez will get a good image of the diffuser and we could see.

The times were not encouraging but Komatsu seemed to be decently optimistic and basically said that "it's not like Melbourne" so I'm not really sure how to interpret that. Sounds like only Bearman got the new floor on Friday (you would think Ocon would get it as the more experienced driver/points leader but who knows). Obviously FP2 was a mess for everyone but they set their times on mediums rather than soft I think.

I can see this as a possibility. The only thing is, we've heard so much over the last 5+ years that aero surfaces work as a system, so it's hard to think of just a patch as workable.

I just checked the F1 app, and both drivers did some running on the Soft as well as the Medium. Let's see what FP3 brings.

Their push laps on the hard didn't look too bad in FP3. However sectors 1 and 2 they did on the softs before the red flag got them didn't look great. I think they were in the 31s in sector 1 which is going to all but guarantee a Q1 exit if that is legit.

They aren't Melbourne screwed, but I think it's going to be tough going on Sunday.

[Mostlyeels]

The team seem happy with the new floor.

Ayao Komatsu: 'In FP2, we pushed the car a lot further, much closer to how we did in Shanghai and actually that gave us answers on the new floor which is pretty good – so it’s definitely better for the problem, and it was a good job done by the aero team and the design office to improve that.'

Amazing job for Bearman to get through to Q3!

Adam Cooper on "X"
@adamcooperF1on @OconEsteban on P18: "We tried a lot of different things across the cars throughout this weekend. But when we went to the new parts that were supposed to give us more performance, it didn't quite work on my side as it did on @OllieBearman's."
