Key facts
- Formula 1 will increase engine power and decrease electric hybrid power from 2026.
- The power split will shift from approximately 53%-47% to 58%-42% in 2027 and 60%-40% in 2028.
- Fuel flow allowance will increase by up to 13% by 2028.
- The changes aim to improve qualifying performance and address energy management issues.
- Earlier plans for a larger engine power increase in 2027 have been scaled back.
Formula 1 is set to shift towards more engine power and less electric hybrid power starting in 2026, with the pace of change slower than initially planned. The governing body FIA announced an agreement on Wednesday that will see the power split move from the current approximate 53% engine and 47% electric to 58%-42% in 2027 and 60%-40% in 2028.
This adjustment means cars will be allowed to use up to 13% more fuel flow by 2028, typically deploying less electric power. The FIA stated the changes are intended to address energy management and fuel flow characteristics, aiming to make qualifying more competitive without negatively impacting racing quality. The revised plan includes a 20kW increase in engine power for 2027 and a 50kW increase for 2028, a reduction from earlier proposals.
Audi had previously expressed concerns regarding the cost implications of significant changes, especially as teams are already designing cars for 2027. The 2026 regulations were initially designed to improve overtaking through battery power, but led to drivers lifting off power to conserve energy. The FIA made rule tweaks early in the 2026 season to address these issues, and there is broad agreement for further changes next year. FIA President Mohammed Ben Sulayem is also reportedly pushing for a return to traditional V8 engines by 2030 or 2031.
