Formula 1 manufacturers have approved changes to the engine testing rules for 2026 following the compression ratio row that has lasted through the offseason. But after further talks about the new tests, the FIA announced on Saturday that the manufacturers had unanimously approved a “compromise solution” to test the compression ratios. In short, some teams feared that Mercedes had found an advantage, so wanted the rules to be changed. Wolff suggested in a news conference at the second test that by testing the engine when it was both hot and cold, no manufacturers would be at an advantage, and that the rivals were seeking to only have hot testing. Frankly, no.”With the unanimous approval of the new testing that has now been written into F1’s rules, the compression ratio wrangling can finally be put to an end just in time before the season starts in Australia.
