Honda Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Under the ADOU rules, if Honda is only allowed 2 updates till next March then, they need 2 BIG fundamental updates and not rush them, no quick little updates.

If that means the first update won't come till August or September then fine.


But, to be fair to the automakers, these ADOU rules are hamstringing the teams who are struggling preventing them from making the improvements to move up the rankings more quickly. The rules need to be reformed for struggling automakers.

Now, I'm conflicted, if the rules are changed for Honda to catchup then, Honda will just take advantage of those rules and not learn from their mistakes and why they're struggling early on and just continue this cycle of putting uncompetitive engines on the grid the first race of the season. Honda needs to reform their internal structure and culture internally at Honda Japan. It's a systemic problem at the Honda Motor Company Japan. They need to learn from Mercedes, Ferrari and Audi.
I was just trying to point out that they're allowed 2 updates. What they update can be as few or as many things as they want. I think that completely redesigning a whole PU is impossible to do in 1 month or a year. They've been working on this one since 2023. I don't know anything about their internal structure or about anything else.

Hey guys, has Honda or AM said anything on the countermeasures for the vibrations?

Alonso said he was pleasantly surprised and that the vibrations had dropped by at least 80% when he got in the car in FP2, but then the next day they returned just like before. He said the team told him they haven't changed anything, so they have no idea why it was so much better then suddenly terrible.

Highly suspect to be honest.

No reason not to push a proper reliability update/re-design as soon as possible. Miserable races like these don't help anyone.

Really interesting but that means when they find out what cause it, maybe it is easy to fix.

Something weird happen this weekend???
No vibrations on Friday but they came back on Saturday without any changes to the Car!!!

Attack on the Honda PU ECU?
Inside job?
From the Pits?
From Trackside?

This would explain why Honda and AM really do not know what is the cause.
I only heard that Honda thought they was down a little on ICE power and they believe it's because they are at 16-1 CR and others are higher.

Maybe Some team saw AM Honda as their only comp and are taking the game to the next level to make sure they win before everyone else learns their secret of their more powerful ICE???

Not sure about that TBH, but its definitely intriguing.
Reduced vibrations on friday and they return on saturday/sunday....
could be due to the engine mapping? as they start pushing the vibrations appear?
As the combustion gets stronger the ICE begins to vibrate?
I wonder if the vibrations appear at a certain RPM or just constant.

unfortunately if the vibrations came back for Quali and Race this points to them not understanding where this comes from...
any thoughts guys?

The measures to fix vibration worked on friday but they did not run them during the race.for the next race they expect no vibration so the only question is why did they not use parts from friday

The lower vibrations in FP2 might be temperature or humidity related or something.

That was also my thought. Temperature can affect the stiffness and thermal expansions of the entire car.

Ok so it appears they did indeed test something and "the item" was successful in greatly reducing the vibrations but they chose not to implement it during subsequent sessions and the race on "reliability grounds". Interesting whatever this fix is that it concerned them enough to not use it for the moment.

But they now believe it's a hugely positive sign and they know what needs to be done between now and Miami. Mike Krack now believes the vibration issue will be completely solved by Miami and this conversation will be a thing of the past.

This cannot come soon enough so they can work on turning up the wick and introducing performance. That engine is turned down so far that this whole "130R every car losing 50kph and revs dropping looks bad" chat, the Honda's sounded woefully low revving and there was some resonance that onboards sounded like the engine had a big end knock lol. It was depressing.

Good! finally some encouraging signs, it's interesting that they decided not to use them for Q and R due to reliability concerns, that makes me think that whatever the changes are they are not in the fixing points it's got to be something internal, in my mind at least.

thanks for keeping this thread with posts like this guys!

Maybe a temporary fix run during practice, they tested to check if it was working, with 1 month break we can expect cars some performance and potential of the chassis..

Maybe was actually fix for the whole weewkend (they were able to finish the race) but for keep trying to do some engine mods due to "reliability and safety reasons" the Team told Alonso to say that vibrations still there?
