FIA announce official F1 vote over Mercedes compression ratio controversy
An update on the geometric compression ratio controversy affecting the 2026 F1 season has been announced following a meeting of the F1 commission. The discussion focused on measuring compression ratios within power units after Mercedes discovered a loophole allowing for a power increase. The FIA proposed measuring ratios at different temperatures, with manufacturers set to vote on the rule within the next 10 days. If passed, the rule will come into effect on August 1, potentially impacting Mercedes and other teams using their power units. The vote requires at least a 4-1 majority among the five power unit manufacturers involved, including Mercedes, Ferrari, Audi, Honda, and Red Bull powertrains. The decision could have significant implications for the teams and the upcoming races in the season.
