The FIA announced that Formula 1’s stakeholders have reached an agreement to raise internal‑combustion‑engine power gradually. Starting next season, fuel flow limits will be lifted by five percent, and the plan moves toward a 60/40 split between electric and combustion output by 2028.
The adjustment is aimed at easing the energy‑management challenges that teams face under the current hybrid formula, where strict fuel caps force delicate balancing of engine and electric boost. A modest increase in allowable fuel flow should give drivers more strategic flexibility and reduce the pressure on engine‑map optimisation.
Implementing the change will require manufacturers to adapt engine software and possibly hardware to handle the higher flow rates. The 60/40 target sets a clear hybrid ratio for the 2028 season, signalling a shift toward greater electric contribution while keeping the combustion engine relevant. The first step will appear on the grid next season, with further refinements scheduled through 2027.
