Formula One is adjusting its engine regulations for 2027, increasing combustion power while cutting electric output. The decision follows a virtual meeting of team bosses, power unit manufacturers, and F1 management convened by the FIA.
The changes will boost the Internal Combustion Engine (ICE) by approximately 50kW with a higher fuel flow, reducing reliance on the Energy Recovery System (ERS). The current 50-50 hybrid split will shift to 60-40, enabling drivers to race harder with less energy management.
Sunday's Miami Grand Prix, the fourth round of the season, saw more overtaking and action after early races sparked debate about artificial racing and safety. Drivers had complained about 'lift and coast' tactics needed to recharge batteries, raising safety concerns over speed differentials.
The FIA reported no safety issues from Miami and said further refinements are coming, including improved start safety and wet-weather measures. Visual signaling updates are being evaluated for the Canadian Grand Prix in Montreal on May 24.
