The FIA has finalized changes to the F1 regulations for 2027 and 2028, focusing on energy management. These modifications aim to balance engine power and energy recovery while maintaining the excitement of current racing formats.
The FIA, alongside Formula One Management, teams, and power unit manufacturers, has agreed on a set of regulatory changes for the 2027 and 2028 F1 seasons. These changes address energy management concerns that surfaced during the early races of the 2026 season, particularly under the new power unit framework.
The proposed alterations aim to improve energy management and fuel flow characteristics, ensuring that qualifying sessions remain as thrilling as ever without detracting from the exciting racing that the current regulations provide. The modifications involve a phased adjustment of the contribution from the Internal Combustion Engine (ICE) and the Energy Recovery System (ERS) throughout the 2027 and 2028 seasons.
Key changes include boosting the maximum power output of the internal combustion engine from 400kW in 2026 to 450kW by 2028, with an increase in fuel flow by 13% over the same period. Meanwhile, the Motor Generator Unit - Kinetic (MGU-K) will see its maximum power remain at 300kW, but with increased harvesting power, rising from 350kW in 2026 to 400kW in 2028. The power split between the ICE and MGU-K will also shift, moving from a 53/47 split in 2026 to 60/40 by 2028.
These adjustments are complemented by measures related to power unit supply conditions and race operations, as well as updates to the financial regulations. This collaborative effort continues the partnership between the FIA, FOM, teams, original equipment manufacturers (OEMs), and power unit manufacturers, aiming to refine the framework and tackle operational challenges.
The FIA is now moving swiftly to formalize these changes, providing all involved parties with the clarity and time needed to adapt. The proposed changes will be presented to the World Motor Sport Council for approval on June 23 in Macau.
