Mercedes and Red Bull receive FIA approval to use their engines

A minor scandal recently emerged in the world of Formula 1, when several teams lodged complaints against Mercedes and Red Bull over an alleged attempt to circumvent the regulations. The FIA has now responded.

Details: According to Motorsport.com Italia, Mercedes and Red Bull are permitted to use their engines. In the FIA’s view, the 2026 combustion chambers of Mercedes and Red Bull are legal. This applies if a compression ratio of 16:1 is measured during testing at room temperature, even if it increases when the engine is heated.

Ferrari, Audi and Honda had complained that Mercedes and Red Bull had allegedly found a way to bypass the rules and develop engines with a compression ratio of 18:1, while the 2026 regulations set a maximum of 16:1. If true, this could increase power output by around 15 horsepower, potentially providing a competitive advantage on track.

Reminder: Max Verstappen has declined the status of reigning Formula 1 world champion and will not race with the number 1 next season. However, he also will not return to his iconic number 33.
