The FIA has adjusted F1’s regulations after the Mercedes engine controversy.
Formula 1 bosses have confirmed a rule change to close a loophole Mercedes is believed to have exploited in the engine regulations. Ferrari, Audi and Honda suspected Mercedes of exceeding the compression ratio using thermal expansion, prompting a regulation tweak controlled in both hot and cold conditions from 1 June this year and only in operating conditions from 2027 onwards. The decision aims to end the engine compression saga before the 2026 F1 season begins. The amendments to the FIA Formula 1 Regulations were unanimously approved, following extensive feedback from drivers and teams. Mercedes boss Toto Wolff initially downplayed the saga, calling it a “storm in a teacup” during pre-season testing in Bahrain. The regulation changes mark one of the biggest in recent memory, with ongoing evaluation and technical checks on energy management matters.
