I think battety deployment is key. I have seen Audi videos where battety is deployed and finishes very quickly. Honda might have more Battety deployment over a longer period and quicker recharge. So top speed might not be max and ICE rpm will not be max, but battery will be longer, less fuel used as well.
Battery capacity is limited (4 MJ), this is 1.11111 kWh or if we translate it into kW/secs it is about 4000 kWseconds.
MGU-K power is limited (350 kW).

In ideal world, this means you can deploy full charge at full power for 4000/350 = 11.43s

Differences between the teams can only be in efficiency (how much of that battery really goes to the wheels) and whether teams are using full 350 kW or a lower amount.

The MGU-K ultimately driving through three gearset interactions on its way to wheels !

Firstly, K to crankshaft, then to lower gearbox shaft, up to gearbox "secondary" (directly above) then output from that through a 90 degree turn (longitudinal to cross ways in chassis) finally onto differential crown wheel in driving the half shafts.
If you count the 90 degree and that component then driving the diff, then logically its a total of four swaps from one gear tooth set to another. All with characteristics in loss of their own.

Honda built a PU to the letter of the rules.
They was giving hints there was problems with the new PU Formula.
They believed everyone was having the same problem and didn't talk to F1 because it's not in their nature and the other manufacturers didn't share any problems with the new formula.
The first clue Honda had that something was wrong is when someone leaked that RB & Mercedes was using higher CR.

First testing and Honda finds out they are the only manufacturer that made a PU to the rules.
Everyone else is cheating in someway to make the PU work!!!

The talk is they are running 18-1 up to 20-1.
It looks like the Manufacturers that are on the only side of the CR(Audi & Ferrari) was the ones pointing the finger at RB & Mercedes(using the same piston manufacturer???)

It looks like the formula was wrong to make the expected 50/50 power.
Needed a more powerful ICE.

Ah, so it's not Honda's fault, but the competing engine manufacturers'.

That's an excuse gallery.

So I disagree!

Honda just being Honda.

They do not believe in the racing motto...if your not cheating, your losing.

Now that they seen what others have done, they will make it better.
They now know the baseline standard.
It just depends how fast by their Leadership(it looks like their Leadership already gave them the thumps up and they was already working on the grey area higher CR ICE.
We all know who was leading that team...;)~

Such nonesense. The competition didnt make the Honda PU slow and unreliable. Honda did.

16:1 is 16:1. Doesn't say anywhere you can have a different CR. It just says it will be measured in a condition that isn't even a realistic or operating conditions. The English diction serves well for the grey areas where as the foreign language teams seem to read the regulations to its exact diction. If telemetry proves that the only way that Mercedes and RB engines are able to achieve the power figures is by exceeding the 16:1 ratio it should be a pretty clear decision for the FIA.

Do you think the issues are only the 16:1 CR? They could not even run on the last day...I highly doubt this was down to compression ratio tricks of the compretition...

Honda was one of the PU manufacturers that voiced their concern over other manufacturers using a potential loop hole and from what I've gathered Honda did abide by the 16:1 CR in accordance to the prescribed testing procedure. Andy Cowell did mention every manufacturer, including Honda, are pushing the limits, so I would expect it is reasonably possible that Honda initially did not think to go beyond it but were compelled to after learning others had tricks up their sleeve.

As for the last day, they probably should have brought twice the number of spare components. The problem with overheating is that you don't know what structural damage/weakness has been incurred without a thorough inspection of the components. It generally starts in the form of the warping of parts that cause misalignments that then lead to vibration, fatigue, mechanical wear and possible contamination/cavitation/blockage of a closed loop system. How/if the battery/CE overheated I'm sure Aston and Honda have been working out.

F1 Gate Article Translated.
A good explanation from Watanabe about Honda's plans for March 1st and beyond.
Key point is again a synergy and MotoGP. In the past, Honda tapped the motorcycle R&D resources for its cylinder plating that led to the success of the RedBull Honda era.
Note, the title is about the 2nd half of the article which talks about the future of F1 if it went normally aspirated.
What are the conditions for Honda F1 to remain HRC President Yasuharu Watanabe: "Hybrid is a premise"

Aston Martin Honda F1's new challenge has faced difficulties since the testing phase. But Honda is trying to bounce back with a precedent from its struggles with McLaren.

The key to this is the technical synergy between F1 and MotoGP. Honda Racing (HRC) President Yasuharu Watanabe talked about the current situation and future prospects.

Exploring collaboration between F1 and MotoGP
"It's clear that we're not happy with where we are at the moment," said Yasuharu Watanabe.

"We have identified a lot of areas that we need to focus on before the opening race. Normally, we would have liked to do more laps and collect more data during testing, but unfortunately we faced unforeseen problems. We are currently dealing with them."

From next week onwards, it will be impossible to change the specifications of the power unit in principle, and the homologation (certification) will be reached at the end of the month.

"At the end of the month (March 1), the engine will have to be homologated, so the hardware will be frozen, and based on that premise, we will pursue how to make the power unit function optimally."



"We are strongly pushing to build a collaborative system between the two premier categories of F1 and MotoGP, and we are looking at how we can transfer and share knowledge between the two projects and connect them to achieve success in their respective championships."

50:50 power distribution and electrification challenges Honda appears to be one of the most struggling manufacturers under the current regulations, but there is a technological turning point behind it.

"We had to develop a different internal combustion engine than last time, but the approach to the heat engine itself is the same."

"But now electrification is much more important, and how we generate electricity and how we supply it is key. The 50-to-50 distribution of output is clearly the most important item."


In addition, responding to sustainable fuels is also a new challenge.

"Sustainable fuels are also an additional challenge, and this year we had to integrate it relationship with Aston Martin and the partnership is strong, despite the difficult circumstances.

"I have a very good relationship with the team and we have a deep collaboration, and I find Lawrence Stroll's approach and vision to be great."

"I have worked with Adrian Newey on successful projects in the past. We value our relationship with him."

"Andy Cowell, who is the main point of contact for power unit development, is also a very talented person, and on the track our staff is working with Aston Martin's personnel to build the foundation for a long-term winning organization."

Honda's future regulations
Honda's participation in F1 is not determined by mere performance. The direction of future regulations will also be an important factor in determining the future.

While the possibility of reviving naturally aspirated engines was being discussed, Yasuji Watanabe presented clear conditions.

"It is desirable that the regulations of the future are consistent with the direction of Honda's automotive technology, our future is in electrification and hybridization"

"Therefore, the power unit must have a certain hybrid system. That's what it takes for Honda to be in F1."
The fusion of F1 and MotoGP, adaptation to the 50/50 electrification era, and alignment with future regulations. Honda's re-attempt is at a major turning point, both in terms of technology and philosophy.

Neither Ferrari nor Audi are operating in english speaking countries, and haven't made a botched power unit. And even more, seems quite implausible that every manufacturer bar Honda are cheating with CR, because they are protesting against doing so.

From my point of view, utter incompetence has nowhere to hide.

So honda are incompetent because they are not cheating? The Honda pu was running the engine on save mode because of battery overheating since Barcelona. So ones they address that issue we will see the real hondapowerunit but for now we haven't. So are people angry hurling insults but doing that with limited info.honda had to change parts of there pu since newey arrived but they were limited in time.
