Formula 1's governing body, the FIA, has agreed to a two-step plan for engine design changes following significant driver criticism of the current power unit regulations. Drivers have expressed concerns that the nearly equal split between internal combustion and electric power diminished qualifying challenges. As part of the agreement, the ratio of internal combustion engine (ICE) power is set to change from approximately 50-50 to 58-42 in 2027, and ultimately to 60-40 by 2028. The engine suppliers will increase fuel-flow to the ICE, aiming to improve performance and restore a more competitive environment during qualifying. The FIA will also allow certain manufacturers to make engine upgrades based on performance rankings, with Red Bull reportedly having the most powerful engine this season.
