Formula 1 bosses agree engine rule changes for 2027 and 2028 seasons
Formula 1 bosses have agreed to alter the sport’s engine regulations for the 2027 and 2028 seasons to increase internal combustion output.
The 2026 campaign introduced a strict 50-50 division between internal combustion and the energy recovery system.
However, motorsport executives have now approved a move away from this balanced configuration for the V6 hybrid power units.
When the 2027 championship begins, the technical framework will mandate a 58/42 split in favour of the traditional combustion element.
Further combustion increases planned
This regulatory adjustment will be extended again the following year.
For the 2028 season, the combustion contribution will rise to 60 per cent of the overall power output.
Consequently, the electrical component of the hybrid system will decrease to account for the remaining 40 per cent.
These technical directives mark a swift recalibration for the pinnacle of motorsport following the major regulatory overhaul implemented in 2026.
Modifying the specifications so rapidly suggests an ongoing effort by the governing body to refine on-track performance and address complex engineering challenges.
