Firstly, in terms of homologation upgrades, the FIA defines two tiers based on the performance deficit.ispano6 wrote: ↑29 Jul 2026, 15:55This post is not proof. The proof is the number of ADUO that was granted. The ADUO power range of the teams was not openly disclosed so saying Honda was down 6-8% doesn't have validity whatsoever. They toss this around while the real ADUO allowance granted should more accurately place them in a theoretical range. So, as far as I know, Honda was granted 2, but will only bring one. The 2nd team developing next year's is working on a completely different fuel flow while eying what the ADUO 1 performance brings. If they were leaving 5 ADUO opportunities on the table for 2026/7 that would put them at 6-8% . But there NEVER once has any mention by anyone publishing Honda's ADUO allowance stated they had more than 2. And by regulation 2 ADUO equals 2-4% down on ICE HP. So unless the Allowance per range was reduced or Honda was granted 6 changes and is only bringing 1 so far. With Honda never say never and any ADUO allowance they could bring legally would be brought if there isn't a severe addition to cost caps. But those costcaps also increase per ADUO range. From the Japanese media I've read, it was implied the ADUO opportunities and cost cap are STILL limited and that the reason they're only bringing one ADUO upgrade is to make the most of the ADUO they will spend or have the budget to. I think this 6-8% and the number of allowances granted are mismatched and are thrown out just paint the narrative that they are soooooo far behind when in truth by FIA analysis of PU found it to be less. Never trust what the echochamber western press regurgitates as it's just for sensationalism and click bait.F1RAM wrote: ↑29 Jul 2026, 14:04

A manufacturer assessed to be between 2-4% below the highest-performing ICE is granted 1 additional homologation upgrade in the season it is awarded (N), and 1 further upgrade in the following season (N+1).
For manufacturers with an ICE deficit ≥4%, the FIA permits 2 additional homologation upgrades for season N and a further 2 for season N+1.
These upgrades may be introduced from the first competition following the assessment period in which they are granted. In layman's terms, this means if the 1st evaluation period ends at Round 6, the first engine upgrade may be introduced at Round 7.
It is important to note that ADUO upgrades are not cumulative.
They are only awarded following the first instance in which a PUM is assessed as meeting the eligibility criteria.
ADUO homologation upgrades are not cumulative within a season and will only be granted following the first occasion that the PU Manufacturer is assessed by the FIA as eligible for ADUO.
