It's not because it was reported by someone from the BBC, it's because it was reported by Andrew Benson, who has proved to be very reliable in his F1 reporting for decades. He doesn't claim gossip as fact.
anyway, 100 kW is huge, ~134 hp.
It is so frustrating that there are only 8 days left to submit final specifications.
I'll be surprised to see that apply to Honda. We have ADUO this year.
How the ADUO System Works
Performance Monitoring
- Early in the season (first ~5 races), the FIA monitors the average performance of the internal combustion engine (ICE) component of each manufacturer’s PU.
- ICE power output is compared with the highest-performing PU.
Qualification for ADUO
- If a manufacturer’s ICE power is more than 3 % below the highest at the specified checkpoint, they can qualify for ADUO.
What ADUO Lets a Manufacturer Do
- When a PU manufacturer qualifies for ADUO, they can:

Develop upgrades to the PU beyond the normal mid-season restrictions — which otherwise are tightly limited in F1.

Use extra power unit test-bench hours — giving more scope to try and improve performance.

Potentially re-homologate parts (within strict guidelines) to improve competitiveness.

In some cases, financial cost cap relief is also factored in for development costs.
In sporting regulations, PU manufacturers that meet ADUO criteria are granted additional ICE operation hours (e.g., +30 % in a 12 month period) for development after the fifth race.
When It Applies
- The ADUO is mainly assessed once early in the season (after the first ~5 races).
- The FIA monitors performance to decide who qualifies and how much uplift (if any) is granted.
- The FIA also retains the right to revoke ADUO status if performance suddenly improves in a way that creates imbalance.
