The Honda PU thread from 2015 is not the longest thread on this forum for nothing. There are a lot of Honda fans and they are proud of the brand. Reading through the replies in that thread is very interesting, particularly from people "in the know". The timeline to fix issues and catch up ended up taking so much longer than what people were expecting (even within Honda). Some examples from 2015 from Wazari (who has connections inside Honda).Leon Kennedy wrote: ↑27 Feb 2026, 15:37All correct, but they have publicly admitted that they are behind on the ICE program. I don't understand what's wrong with admitting that Honda made a mistake? I mean, guys, they admitted it too. Reliability issues are one thing, performance issues are another.
I also highly doubt McLaren will switch engine suppliers nor will it take Honda 4 to 5 years without a podium. McLaren Honda will be on the podium in 2016.
I wouldn't be surprised if Honda holds off on the upgrades for Hungary and waits until after the summer break to introduce the upgraded PU. 70 to 80 HP is a big jump but I think the PU always had the capacity to produce the HP. However at these higher settings, reliability becomes a bigger issue.
I know there are four basic tuning trims right now and they have been running at level 2 for the last two races. They are down about 90 HP in that trim in my opinion. I am told that level 4 trim should be equal or slightly higher than Mercedes' estimated output. Of course this is all hearsay and speculation.
My takeaway in hindsight is that PU development takes longer than you think, especially if you have fundamental issues. I would treat claims that "things will be fixed after race X" with extreme caution, even if they are coming from people within Aston or Honda.As I mentioned before, the folks at Sakura are very pleased with their latest ICE (2016) and think it lacks nothing in terms of power compared to Merc and Ferrari. They also think there is more power to be had from the ICE before official winter testing dates.
Instead of a single longer and flatter shape like before, the 2026 Honda design splits the battery and control electronics into two tiers, which seems to be even more aggressive than what is demanded by the new rules requiring the battery to be contained within the survival cell.
I’m pretty sure those battery packs are made up of many smaller batteries. I’m not sure it makes any difference whether the batteries are stacked lengthwise or arranged lengthwise and vertically. Obviously, there is a cooling aspect to the batteries. Nor do we know if the placement in the Honda released image is the way it will actually be positioned in the car. We also don’t know if the second-tier battery in that picture is actually a battery and not the control box shown on the side in the other picture.HPD wrote: ↑27 Feb 2026, 16:12Instead of a single longer and flatter shape like before, the 2026 Honda design splits the battery and control electronics into two tiers, which seems to be even more aggressive than what is demanded by the new rules requiring the battery to be contained within the survival cell.
Honda has previously said a desire from Aston Martin to make the overall engine length shorter and more compact prompted revisions to most of the engine's peripheral equipment and how it is integrated into the car, although the design of the engine itself did not have to be changed.
gees, how painful was that to watch ?SSJ4 wrote: ↑27 Feb 2026, 01:14I was looking at the race sim vs vcarb. a lot time was lost in straights which isn't a surprise. but equally they were losing a lot in slow speed sections. Is that gearbox related? or they just havent had a chance to dial in a proper setup due to a lack of solid running

- Honda chose to leave right when they were becoming successful with Red Bull, and then jumped back in later than everyone else.
- It's still not clear how much personnel from the successful Honda engine was lost to RBPT or the other PU manufacturers in the meantime.
- Then Newey comes, late.

- For some reason, such as cultural communication issues or too much Newey-worship, no one pushes back on these demands.
- On top of that Aston is trying to make their own brand new gearbox for the first time amongst other things, and it looks like they don't have good integration testing processes for all those things yet.
The same exact problem with McHonda back in the day: Honda was forced to join a year before they were ready, with unreasonable specs. I estimate that between the late recommitment and Newey's demands they were robbed of even more time.
If you want to be a works team, you have to work with your PU manufacturer, not treat them as a subcontractor. I can't imagine the Ferrari or Mercedes chassis people making such demands of their engine people. They should have done what Cadillac is doing -- stick with their known PU until they are sure they can manufacture a gearbox and everything themselves, and make their own engine last. Were they still using a Mercedes engine, Newey would have had no choice but to design around it.
1. The Japanese personnel were still taken off the project for a couple years, I'm assuming. Sakura just had a support team we don't know where the rest of the F1 R&D people went. Even if they were transferred elsewhere within Honda and brought back they still lost many years. This is Honda's fault for jumping out and in.diffuser wrote: ↑27 Feb 2026, 17:35- HONDA lost 0 personnel in Japan to RBR.upsidedowntoast wrote: ↑27 Feb 2026, 17:09Putting in my 2c as an outsider without emotional attachment to either Honda or AMR, this project seemed doomed for failure in a way that's everyone's fault.

- Honda lost all the personnel in the UK, none of them did R&D on the Honda PU.
- We don't know how many of the R&D people that were in the OLD F1 project at Honda, returned to the new project.
- Not sure where this subcontractor BS comes from.
- I'm, 100% sure that the communication between Honda and AMR is the same as it was between Honda and RBR.
- You're making an argument that throws away the biggest advantage for being a works team.
I'm not saying that it's wrong to make changes. I'm saying that if you make late changes, you should accept the difficulties that come with that.diffuser wrote: ↑27 Feb 2026, 12:41I do not subscribe to the view that Honda should be blamed for everything, nor do I believe you have demonstrated that the changes Honda was asked to implement were sufficiently complex to have caused their reliability issues.
Furthermore, I do not favor the decisions made by the AM F1 team, which resulted in a seventh-place finish in 2025, over the changes proposed by one of Formula 1’s leading designers.
Can Honda make changes at engine when ever want or FIA must allow first? When will fia allow changes?diffuser wrote: ↑27 Feb 2026, 17:35- HONDA lost 0 personnel in Japan to RBR.upsidedowntoast wrote: ↑27 Feb 2026, 17:09Putting in my 2c as an outsider without emotional attachment to either Honda or AMR, this project seemed doomed for failure in a way that's everyone's fault.

There are reviews for being 2-4% being after races 6, 12, and 18. I think there's a separate thing where they might raise the budget cap if a team is so far behind they need to catch up.hsg wrote: ↑27 Feb 2026, 19:15Can Honda make changes at engine when ever want or FIA must allow first?

So they will use this engine/battery up to race 6? But they will not finish any race before they fix these problems.upsidedowntoast wrote: ↑27 Feb 2026, 19:55There are reviews for being 2-4% being after races 6, 12, and 18.
