What the FIA decided on 10 November
The final 2026 ADUO assessment, covering races 12–18, generated no additional homologations. The FIA says performance gaps evolved but is keeping its measurements confidential. The next review will cover the opening six races of 2027.
Previously awarded allowances
The table summarises opportunities communicated for the first review period. They are homologation allowances, not evidence that an upgrade has already been used. The second assessment also added no homologations.
| Manufacturer | 2026 | 2027 |
|---|---|---|
| Mercedes | 1 | 1 |
| Audi | 2 | 2 |
| Ferrari | 2 | 2 |
| Honda | 2 | 2 |
What the mechanism measures
ADUO provides development opportunities for manufacturers that reach the FIA’s deficit threshold. The assessment concerns the internal combustion engine, whereas overall power-unit performance also depends on electrical energy recovery and deployment. The federation’s explanation distinguishes development support from direct performance equalisation through ballast or fuel flow.
What happens to unused opportunities
The FIA states that an opportunity assigned to a particular season must be used within that season; it cannot automatically move into the next year. An allowance awarded separately for 2027 retains its own validity. The table’s columns therefore represent separate allocations rather than one transferable stock of upgrades.
How to interpret the decision
APEX analysis: the absence of new homologations does not demonstrate that engines have become equal or reveal an updated power ranking. A team’s championship success cannot isolate its engine’s contribution from its chassis either. Assessing an upgrade requires establishing what is actually introduced and what can be verified on track.
