If it is a zero size concept and mgu-k and battery design is for making it as small/thight as possible, there can not be much place for weights. Mass dampers are using at motogp and I remember a comment about it that only putting it on the vibrating part is not a solution. Arranging it takes time. Of course this is a car and it works quite different.
Alex Brundle said that Honda said that it was a resonance is the ICE that the chassis is Amplifying.mzso wrote: ↑28 Mar 2026, 20:31Because the chassis is a huge piece of very strong and rigid structure, meant to survive even the biggest impacts. On the other hand many parts have the potential to vibrate, move against each other.ispano6 wrote: ↑28 Mar 2026, 03:36つっかえ棒のような部品.

Though you highlighted struts, in no way he says it's because, or for the chassis. I guess the K might be vibrating around because it's only mounted at one end to the engine, which could certainly magnify the problem. Struts would help here for sure. He also says that the PU is the cause that generates the vibrations.
I literally translated it twice in that entry that has the same meaning.
And yes, it does support my initial conjecture about chassis vibrations.
The issue alone is not due to the PU. The chassis itself contributes. Why you cannot accept this is beyond me.
I trust these Japanese publications 1000x more than italian or british press. Especially when they are Japanese writers quoting Japanese personnel.
Not sure if Honda ever did that. I do remember them being open about stuff that was wrong after it was fixed.
I rather think an engine re-design is needed. So whatever can be done in the meanwhile helps.diffuser wrote: ↑28 Mar 2026, 05:05I think this is actually the worst-case scenario. My money is on them not having a clue what the problem is. If they knew what the problem was, they wouldn’t be wasting time trying to isolate the battery and the steering wheel from the vibrations. They would just tell us when they’ll fix it and explain what needs to be changed.
I was talking about coming out of a curve. More weight to turn, have to wait longer for the weght to transfer. You'll get wheel spin if you don't wait.etusch wrote: ↑28 Mar 2026, 21:40Heavier car can accelerate slower but throttle late ? I don't think so.

They're good at one short piece between turns 14 and turns 15 but everywhere else, they are very slow.
1 - Down the straight into turn 1 they're 20 KPH slower than Piastri and Leclerc (They lose .5 of lap time before turn 1).
2 - 10 KPH down through the Ss
3 - 5 KPH down between turns 7 and 8.
4 - 10 KPH between 9 and 10
5 - 20 KPH between 12 and 13
There is a lot of evidence that the PU is down on power and a lot of evidence that they are late gettting on the throttle coming out of corners. Meaning lack of traction, too heavy, etc.
We don't know how much extra fuel they're carrying, how much weight in counter measures they're carrying. Lots of unknowns. A car that's 40KG heavier is gonna be slower in all turns than the 40KG lighter car.
That would be insane... Fix vibration as soon as possible via usual reliability update path. Then whatever improvements they can do push it out before the season ends. Then keep improving whatever possible in the remaining time for the second update.
All the cars on the F1 grid are zero size and they have all tried to make their cars as small, tight and as light as possible. Stop with that BS. They've been doing the "small, tight and as light as possible" thing in F1 since the 13th of May 1950. I guarantee you no teams have hundled in a meeting and asked "You think if we carry an extra 100KG we'll be faster ?".etusch wrote: ↑28 Mar 2026, 21:55If it is a zero size concept and mgu-k and battery design is for making it as small/thight as possible, there can not be much place for weights.

If it is fuel and you need only one lap, and if they are aiming to finish the race, low fuel, then I think they can run the car with low fuel for one lap.

These engineers have access to the highest amount of R&D funds in their domain, how can they not solve something that is a prerequisite for a functioning vehicle?
I wonder if they already know its an issue they can not solve without up a ground up redesign and are not willing to say it out forthright.

I am aware, and I still stand by my statement. I refuse to believe the world's best minds with access to insane amount of money can not figure out why their vehicle is not functioning at the expected baseline.diffuser wrote: ↑28 Mar 2026, 23:51You know there is a PU budget CAP right?makecry wrote: ↑28 Mar 2026, 23:37I am a bit perplexed as to how the world's best engineers with an insane amount of money at their disposal can not diagnose and solve a vibration issue.

It's pretty obvious to me that you wouldn't use it if you don't know how to fix it. Another reason could be that there are long lead time to creating heads and blocks, connecting rods, etc.mzso wrote: ↑28 Mar 2026, 23:26That would be insane...

Either that or keep the larger scope re-design for the second and deliver a simpler improvement earlier this year. (However this would risk something similar to this year's fiasco to happen)
Somehow they've all managed to make it work.etusch wrote: ↑28 Mar 2026, 23:54That doesn’t mean AM have space, it just means others also have no spacediffuser wrote: ↑28 Mar 2026, 23:47All the cars on the F1 grid are zero size and they have all tried to make their cars as small, tight and as light as possible.

A very good point. It is something that Ferrari, Mercedes, and Red Bull could identify right away through multiple teams. Exclusivity agreements are overrated.
Newey's Mclaren MP4-18 suffer similar fate and end up the team has to replace it with D spec of previous season car MP4-17D. If the car has got fundamental design issue and unstable, it will be much harder to fix.makecry wrote: ↑28 Mar 2026, 23:37I am a bit perplexed as to how the world's best engineers with an insane amount of money at their disposal can not diagnose and solve a vibration issue.
