Mercedes, and doubtlessly Crimson Bull Powertrains, are mentioned to have discovered a approach to circumvent what’s stipulated within the technical laws, in line with which the compression ratio should adjust to the required worth throughout checks carried out at ambient temperature.

As has beforehand occurred in F1, a easy change of employer by a employees member may be sufficient to disclose a workforce’s or engine producer’s actions to direct rivals.
The ball is now within the FIA’s court docket. “The laws clearly outline the utmost compression ratio in addition to the strategy for measuring it, primarily based on static situations at ambient temperature,” the governing physique said.
“This process has remained unchanged regardless of the discount within the permitted ratio for the 2026 season. It’s true that thermal enlargement can affect dimensions, however the present guidelines don’t present for measurements to be carried out at elevated temperatures.”
