2026 Scuderia Ferrari HP F1 Team

I am not sure about if they are allowed to make a new engine every year, or is Mercedes stuck with their current engine for the following years if it is the best or equal?

Performance is tested every 6 races. Mercedes are not locked in to their current spec all season if someone is able to bring updates that put them ahead.

If Ferrari do leap frog Mercedes by enough, then Mercedes gets the ADUO at the next test comparison

My question is not about this.
If let's say Merc keeps its advantage or equality, then will they be able to upgrade their engine for next year? Or they will have to race in the next years with the same homologised engine till anyone leapfrogs them too much?

You can bring a new PU at the start of each season regardless of ADUO.

I asked something similar I the general car thread. Someone kindly gave me the following:

"If you look up the FIA technical regs on the FIA website, the is a table (in the appendix section, I believe) with ticks for "normal", allowed homologated changes year-by-year, and ADUO changes. Essentially from 2027 onwards, teams are allowed to homologate most ICE-related new components in odd years (2027 and 2029) and electric components in even years (2028 and 2030). So Merc can still homologate a new ICE in 2027."

I have not looked it up personally yet.

I have spent some time trying to confirm this, it seems the homologated engine carries over to 2027. ADUO is your only path to hardware based performance upgrades.

Do back to the original question. If the regulations don't change in a way that requires architecture or pu changes at a hardware layer, then Mercedes will remain with the same power unit until such time the qualify for ADUO.

Thanks for the answers, even if they are all over the place

Not sure how you came to the conclusion, to me it seems to be exactly as the answer you cited claims:

Appendix C5, 3.3: For the years 2027, 2028, 2029 and 2030, upgrades to the components marked with a checkmark in the table of Appendix C4, in the relevant column for each year, may be carried out. Irrespective of
changes permitted under ADUO according to Article 3.3 of this Appendix, such upgrades must be
introduced for the first Competition of the year when they are allowed and used for the whole
Championship season.

According to Appendix C4, it's mostly ICE-related components in odd years and electric components in even years.
