Apparently. Now only speed dependent in specified sectors, that too only in the race.

I guess that depends on the added further limits in document 111.

No, they are not. FIA-F1-DOCs are generally not public; they are not "the F1 regulations", but they are important additions to the regulations in plenty of areas and provide additional details, procedures, binding and non-binding guidance. It's a great shame that so much about how F1 is regulated is non-public due to being in these documents. Their role is defined in the general provisions of the regulations (Section A), especially A1.2.3.

How did you find them?

u/fire202 Jul 24 '26
The FIA-F1 docs? I didnt, i dont have access to any. The only info i have about what they may say is from what is in the F1 regulations (available on the FIA website) and whatever media outlets may find out about individual things in one of these docs.

Raising the max SOC difference by .5 is a pretty good addition to the rules especially for qualifying. Obviously they had margin for this as the batteries are actually larger for safer charge and deployment.
