F1 Stakeholders Agree Gradual ICE Power Boost For 2027 And 2028 Seasons

Formula 1’s key stakeholders have reached an agreement to gradually increase internal combustion engine power over the next two seasons to address energy management concerns.
The FIA formally announced the agreement on Wednesday, confirming a moderate power increase will come into effect from 2027 before a larger step follows in 2028.
From next season, power units will benefit from a five percent increase in fuel flow, lifting ICE output from 400kW to 420kW without requiring significant hardware modifications.
Alongside the ICE boost, the maximum power output from the electric motor will be reduced from 350kW to 300kW for the 2027 season.
Overtake Mode will remain unchanged at 350kW, ensuring drivers can still access the boost function, while the maximum harvesting limit rises from 250kW to 375kW.
These combined changes effectively shift the power split from the current 53/47 ratio to 58/42 in favour of the combustion engine next season.
A more significant fuel flow increase of 13 percent, which would push ICE power to 450kW and achieve the targeted 60/40 split, will not arrive until 2028 to allow power unit manufacturers additional preparation time.
From 2028, the maximum harvest limit will be raised again to 400kW, while maximum deployment levels and Overtake Mode outputs will remain the same.
The FIA has also confirmed tweaks to the power unit financial regulations, providing manufacturers with the cost cap headroom needed to implement these technical changes, with the proposals set to go before the World Motor Sport Council for ratification on June 23 in Macau.
The FIA said: “The 2026 Formula 1 regulations were developed and agreed in close partnership between the FIA, FOM, teams, OEMs and Power Unit Manufacturers. These latest amendments reflect the continuation of this collaboration with all stakeholders working collectively to refine the framework and address identified operational challenges.”
The adjustments follow a 2026 season that has delivered more action-packed racing but also raised safety concerns regarding high closing speeds between cars on track.
Drivers have voiced the loudest frustrations over the considerable workload required behind the wheel, with heavy energy management demands on several circuits preventing qualifying from being a flat-out effort.
Some manufacturers, including Mercedes and Red Bull Ford Powertrains, had pushed for more substantial changes as early as 2027, while Audi and Ferrari raised concerns over the resources and timelines such changes would require.
The final agreement represents a compromise between those competing interests, favouring a phased and measured refinement of the 2026 regulations rather than a wholesale overhaul in a single step.
