Audi believes Mercedes could enjoy a “significant gap” at the front of F1 in 2026 if it’s fully exploiting the engine compression ratio rules loophole
Audi believes Mercedes could have a significant advantage in Formula 1 in 2026 due to potential tricks with engine compression ratios. This issue has sparked a technical debate with Mercedes and Red Bull possibly running at higher compression ratios than allowed by the regulations. Other manufacturers like Audi, Ferrari, and Honda have raised concerns with the FIA and further discussions are planned for Thursday. The potential gains from higher compression ratios could result in a 10-15bhp advantage, translating to 0.3-0.4 seconds per lap. Audi technical director advocates for robust enforcement from the FIA to ensure a level playing field and fair competition in Formula 1. Despite upcoming discussions with the FIA, immediate rule changes are not expected, with the focus being on developing a long-term methodology for measuring compression ratios.
