I was under the impression that fuels weren't homologated yet because the entire process needs to be carbon neutral, on top of the suppliers obviously wanting some real world running before finalizing.
I am sure all the teams ran current fuels.
I actually heardas Aramco supplies sustainable fuel in F2, it and Honda were the only ones using sustainable fuels.zoroastar wrote: ↑07 Feb 2026, 09:16i heard that people think that they used a hybrid fuel that mixes traditional and sustainable.. and i heard that the only team that may have tested 100% sustainable was mclaren. BUT, its all heresay. nobody has said they know for certain.Rikrikrik wrote: ↑05 Feb 2026, 04:26They used the sustainable fuel during shakedown? anyone confirmed this? or is just a rumor?GhostF1 wrote: ↑05 Feb 2026, 00:46
It's good experience to have, they will now just be pushing the mixtures for F1, they are crucial to the power units stable running. Honda has the lab and departments to develop some fuels in-house. The mixture used in previous power units was largely a mixture developed by Honda with ExxonMobil providing production and refining techniques and this development is what made their combustion technique stable. I'll have to find the Japanese article, they were fairly detailed.
Same with the engine oil, where they were using natural compounds usually found in the cosmetic industry. It was never confirmed but one of them was speculated pretty seriously to be Ambergris (or associated/similar compounds) which has some.. interesting properties.
Again, in that recent Japanese interview with Kakuda, he mentions they've been developing the fuel and lubricants together with Aramco for a while now, so it stands to reason they'd be passing a lot of this knowledge onto them. So it's not unreasonable to assume Aramco and Honda are probably the best combination, for the moment at least, to start with these new fuels, experience wise.
It's also comforting to know that at the Barcelona test, they were using the new fuels and validating the ICE with them.
I also read that Honda used 100% sustainable, but I don't know if it's true. I've also heard rumors from McLaren. However, from experience, I can say that these rumors sometimes turn out to be true. for example, since last year it has been said that the Mercedes PU is the bestsn809 wrote: ↑07 Feb 2026, 14:33I actually heardas Aramco supplies sustainable fuel in F2, it and Honda were the only ones using sustainable fuels.
The engine mapping needs to change based on fuel, so I am sure they practice ahead and will not switch fuels just in Australia.
And what's that an example of? We know nothing of the Mercedes PU.Leon Kennedy wrote: ↑07 Feb 2026, 16:13I can say that these rumors sometimes turn out to be true. for example, since last year it has been said that the Mercedes PU is the best
Wouldn't you think they've been testing with this fuel in the dynos?
Not sure that car was ever in the wind tunnel. Newey did say that the car that they will start the year with will look very different to that. We'll see tomorrow what the day 1 car will look like. I didn't see any pictures of tge AMR26 with aero rakes either?Otromundo wrote: ↑08 Feb 2026, 07:38What intrigues me the most and also interests me is to what extent the results they have obtained in these initial tests correspond to what they expected. In other words, whether the on-track results match the wind tunnel results. Because that would be a big step forward compared to the last seasons. The little reliably accurate information I’ve come across regarding the tests suggests that very possibly it is what they were aiming for, and Fernando's expression reinforces my opinion. I think the results do match; Fernando is a terrible actor.
It would be great news to finally put aside the feeling of being lost with the car's development.
Last season I published a video talking about CoreWeave, an AI program that I found revolutionary and that AM has exclusively. I still believe it could be what the team needs to progress properly and stand out from the other teams. That's exactly why I'm so interested in seeing the results on track under race conditions. If, as I hope, it works... I'm sure we'll have a good time. And the problems with car development will be over.
It is used to simulate the car exactly, its behavior under various conditions, etc., etc. (including also exact models of each track) without resorting to scale models. I recall that the link I shared to a YouTube video was around the middle of the season and that the original video was in Spanish, although it could be automatically translated and the result was very acceptable. In any case, you can see what they themselves explain in this link:
ive seen it reported a couple of times that a lot of teams are having problems with simulations not matching real life, but ferrari and aston martins correlation being good. mostly on f1 news videos, so the info probably comes from one of the twitter channels reporting inside sources. hopefully well have a lot more info in the coming week after testing starts. vamos!!Otromundo wrote: ↑08 Feb 2026, 07:38What intrigues me the most and also interests me is to what extent the results they have obtained in these initial tests correspond to what they expected.

It is possible Alonso may have more fun with these cars than the latest generation of cars. Race craft and tactics may be more important than ever.
I remember last year at this time that Alonso said the car on track felt nothing like the one in their simulator. It will be interesting to see how much improvements have been made with the calibration this time around.zoroastar wrote: ↑09 Feb 2026, 01:26ive seen it reported a couple of times that a lot of teams are having problems with simulations not matching real life, but ferrari and aston martins correlation being good. mostly on f1 news videos, so the info probably comes from one of the twitter channels reporting inside sources. hopefully well have a lot more info in the coming week after testing starts. vamos!!Otromundo wrote: ↑08 Feb 2026, 07:38What intrigues me the most and also interests me is to what extent the results they have obtained in these initial tests correspond to what they expected.

Actually, it seems that the good Lord has wanted to do Fernando a favor. Indeed, as you say, we are almost witnessing the definitive end for Fernando. His last season, then he will become a father... and that's it. That's how it should be, although I would love it and it would also fairly make up for all the disappointments I have experienced over the past few years if something extraordinary, miraculous happened. Disappointments and moments of despair that I suppose are common to everyone here on the forum. Because, perhaps being bold, it seems to me that most of us are here because of Fernando. Not because of AM.zoroastar wrote: ↑07 Feb 2026, 09:02yeah man, its depressing to look at the world through some peoples eyes haha. if i had one wish for the last 10 years for alonso (being a fan), it would have been for him to drive a newey designed car in a team with a budget. and here we are.PinkFloydPulse wrote: ↑04 Feb 2026, 14:27Jesus, so much negativity and scepticism here, you guys are truly and utterly cooked. Wait at least until the first race before all the doom and gloom takes over... my god in heaven, 41 pages on the team thread and we are not even in Australia... Let Newey cook, give Honda a chance, and let the first few races pass before declaring "it's over, we are done!" ...
