FIA and F1 Agree to Boost ICE Power, Cut ERS Deployment for 2027

Formula 1's governing body, the FIA, and team principals agreed Friday to further engine regulation changes for 2027, building on recent Miami tweaks that improved qualifying and safety.

The Miami Grand Prix stood out this season partly due to new rules introduced after driver complaints. Drivers said qualifying focused too much on managing car batteries rather than speed and skill. The changes also followed a crash by Haas driver Ollie Bearman in Japan.

Both issues tied to the 2026 engine's 50-50 power split between the internal combustion engine and the Energy Recovery System, or ERS.

Team principals, Formula One Management and the FIA met Friday to review the Miami results and settled on more adjustments for next season.

"The measures agreed in principle today for 2027 would see a nominal increase in Internal Combustion Engine (ICE) power by ~50kW alongside a fuel-flow increase and a nominal reduction of the Energy Recovery System (ERS) deployment power by ~50kW," the FIA said.

Sky Sports reported the shift would move the ICE-ERS split closer to 60-40. That reduces emphasis on battery charging and returns focus to driver skill and pace.

Drivers, including Red Bull's four-time champion Max Verstappen, criticized the original 50-50 split since its announcement. The setup struggled in the first three race weekends but showed clear gains in Miami.

Engine manufacturers now face added work, but the series aims to fix what isn't working.
