The FIA has confirmed that F1 engine producers will vote on proposed adjustments to the way in which engine compression ratios are measured.
If confirmed, the adjustments might be launched as early because the summer season holidays in August this 12 months.
Mercedes is on the heart of an engine battle with rivals after discovering a loophole within the 2026 engine laws that might give it a bonus this 12 months.

The dispute over compression ratios comes amid claims by rival producers that the 2 producers could have discovered a option to obtain numbers that exceed the theoretical limits set by model new laws for 2026.
The revised guidelines scale back the utmost compression ratio from 18.0 to 16.0. Nonetheless, as a result of the checks are carried out with the engine under full working temperature, questions could come up as to how the bounds are interpreted and utilized.
Following a gathering held by the Energy Unit Advisory Committee (PUAC) with the FIA and 5 F1 engine producers – Mercedes, Honda, Pink Bull Powertrains, Ferrari and Audi – a vote shall be taken to determine whether or not to undertake a brand new proposal that might require compression ratios to be measured in each circumstances.
An announcement issued on Wednesday afternoon mentioned: “Over latest weeks and months, the FIA and energy unit producers have collectively developed a strategy to quantify how compression ratio adjustments from ambient to working circumstances.
“Following validation of this method, a proposal was submitted that from August 1, 2026, compliance with compression ratio limits would must be demonstrated not solely at ambient circumstances but in addition at a typical working temperature of 130°C.
“Voting has been submitted to the facility unit producers and the outcomes are anticipated to be introduced throughout the subsequent 10 days and shall be communicated sooner or later. As with all F1 regulation adjustments, any amendments would require closing approval by the FIA World Motorsport Council.”
