For those who may not know what is going on. Mercedes has found a loophole that allows them to run their engines at a higher compression ratio (18:1 vs. 16:1). This will ultimately give them approximately 15 HP greater. RB may also be going down this path.

The other engine makers (Ferrari, Honda, and Audi) are asking FIA to intervene before the season and stop it.

If the FIA changes its procedures for evaluating engines, the RB and Mercedes could be crippled. FIA had pushed out a compromise that they will run with the 2026 rules and then change them for 2027. Ferrari is said to have filed a protest.
