Formula 1 agrees to 2027 engine rule changes to reduce electric power and improve racing
Consensus Summary
Formula 1 has agreed to modify its 2027 engine regulations to reduce reliance on electric power, shifting the balance from a roughly 50-50 split between internal combustion and hybrid systems to a 60-40 ratio favoring ICE. The changes, announced after a May 8 meeting involving the FIA, teams, and manufacturers, aim to address driver frustrations over energy management, which has led to artificial racing dynamics and safety concerns. Temporary rule adjustments tested at the Miami Grand Prix (May 4–5) were deemed successful, prompting the broader overhaul. Red Bull’s Max Verstappen and other drivers, including Lando Norris, had criticized the current setup, with Verstappen even questioning his future in the sport. The modifications include increasing fuel flow to the combustion engine and reducing hybrid power output from 350kW to 300kW, intended to allow drivers to push harder through corners without energy penalties. Further refinements, such as improved start safety and wet-weather measures, are under review for the upcoming Canadian Grand Prix on May 24. The final package requires approval from the F1 Commission, the Power Unit Advisory Committee, and the FIA’s World Motor Sport Council.

Points of Difference
Details reported by only one source:
- Max Verstappen dismissed the current engine regulations as 'the biggest change in a generation' and said he was 'so dissatisfied he was considering his future in the sport'
- Lando Norris called the Miami tweaks a 'small step' but noted racing was 'not to the level that Formula One should still be at yet'
- The FIA’s World Motor Sport Council and the F1 Commission will review the changes before final approval
- The new engines will require bigger fuel tanks and chassis modifications, necessitating quick agreement among stakeholders
- The FIA explicitly stated the changes would make competition 'safer, fairer, and more intuitive' for drivers and teams
- The Miami amendments resulted in 'improved competition' with no material safety issues identified, according to the FIA
- Visual-signaling measures for the Canadian Grand Prix are being evaluated for potential improvements
Contradictions
Conflicting information between sources:
