The long-running F1 power unit controversy in regards to compression ratios has reportedly taken a new twist.
The FIA announced a potential change in regulations regarding compression ratios in Formula 1 power units during pre-season testing in Bahrain last week. This was in response to concerns raised by several manufacturers, including Mercedes, for exploiting a loophole in the existing rules. The proposed change would involve measuring compression ratios in both operative and ambient temperatures. Following discussions with Audi, Ferrari, Honda, and Red Bull, a plan was formulated to vote on the regulation changes effective from August 1, affecting the second half of the season. However, a new proposal to bring these changes into effect from June 1 has emerged, potentially forcing Mercedes to make adjustments to its power unit midway through the season. Additionally, there are talks of changing the rules entirely by 2027 to measure compression ratios only in hot temperatures, aimed at eliminating any advantage Mercedes might have.
