2026 Power Unit Usage
Discussion
I could ask this question in the Monaco thread, but I am not sure I can handle the inevitable argument that will descend into after the race, so I'll ask it here.
Does anyone know where the power unit usage charts are published and have any of the Mercedes runners fitted new ICE for this weekend to meet the new combustion ratio measurement?
I strongly suspect they are running older engines, power is not important here, and as much as the rest of the PU manufacturers made of the issue, I suspect it is also a non issue.

Thank you.In my head it said when drivers changing PU’s, but I can’t see that now I look.

(..and probably elsewhere in the FIA/F1 pages - I found that site on Google earlier)It’s published by the Technical Delegate before each event, on the official FIA event documents page.

That link is permenant, and will always show the latest event.
Here’s this weekend’s version, Doc 14.

Now it's been announced by the FIA that Red Bull has the benchmark engine in the current field, Mercedes are now eligible for one homologated engine upgrade this season, and all other manufacturers get two upgrades, all with extra cost cap and bench testing allowances. Red Bull get none, haha.

It's almost a shame Horny is not still around, I'd love to see the meltdown he would have over that.

The funny thing is, it's not the PU that is judged to be best, it's solely the ICE component. So now Merc get to improve their ICE inspite of the fact that their PU (ICE + Electric) as an overall entity is already almost certainly the class leader.
I think that's slightly misleading. The metric is peak power of the ICE; peak power of the combined system would presumably exactly mirror peak power of the ICE because the electrical side has a specific power limit that all the teams will reach, because there's no reason not to. So the problem isn't really that the test is "only of the ICE component", the problem is that it's a test of peak power which is not wholly indicative of actual power unit effectiveness.
I guess the other point is that (as far as I know) the deployment algorithms are not homologated so the teams are free to change them as they see fit anyway?

Probably lots of other little efficiencies accriss their system that adds up to the most competitive end result.
RBR will be highly irritated that Merc of all teams now get a chance develop further power.

It's not that simple. It's about deployable power per lap minus the time taken to harvest to the power in the first place. The Merc system seems overall more efficient at harvesting so less time is lost per lap by doing so.
Yes exactly, that was my whole point! The fact that they are measuring ICE peak power is a problem not because they're only measuring the ICE component, but because they're measuring peak power which is far form the be-all and end-all of these power-trains. Redbull have no real right to be annoyed. They signed up to the rules just like everyone else! In fact you could perhaps argue that Redbull Powertrains made a fundamental strategic blunder by focusing on the ICE (which was always going to be the basis for the extra testing allowance) over the electrical side.

Although I'm sure they're annoyed anyway...
Mercedes may take new engines and grid penalties at Monza with the ADUO spec update. https://racingnews365.com/mercedes-facing-f1-penal...
Toto wants to talk about it with Antonelli senior though, as it's their Italian driver in the Italian race.

I thought Mercedes weren't looking to introduce an upgrade, but that article seems to suggest they might run out of engines so why not.Toto wants to talk about it with Antonelli senior though, as it's their Italian driver in the Italian race.
Going back to the original point of the thread, I think it is safe to say at this point that the compression ratio rule change did not hurt Mercedes at all.
