The FIA has shared certain changes stitched after the latest meet involving team principals, FOM and representatives of five F1 power unit manufacturers; an ADUO update has taken place also.
Following the 2026 F1 Miami GP, another meeting was held involving the team principals, FOM and representatives of five power unit manufacturers with the FIA. The first agenda was a review of the changes made post Japan and its implementation in Miami.
Post-Miami review by FIA and F1
The FIA found that the measures ‘were deemed to have delivered improved competition’. There were no compromises on the safety aspect as well. There will be further evaluation and adjustments made still, which includes start-safety revisions and measures to improve safety under wet conditions.
Long-term change agreed in principle
Looking at the long-term changes, there is an agreement in principle to introduce evolutionary changes to make it ‘safer, fairer and intuitive for drivers and teams’. As a result, it has been agreed to increase Internal Combustion Engine (ICE) power by ~50kW alongside a fuel-flow increase.
This will go in-line with a nominal reduction of the Energy Recovery System (ERS) deployment power by ~50kW, from 2027 F1 season onward. The FIA will have further discussions before a final presentation is made for an e-vote at the World Motor Sport Council, for it to become a regulation.
FIA say on ongoing review
A number of proposals to introduce further evolutionary changes to the 2026 FIA Formula One World Championship regulations have been agreed in principle following an online meeting convened by the FIA today and attended by Team Principals, Formula 1 Management and representatives of the sport’s five Power Unit Manufacturers. The meeting began with a review of the recently agreed rule changes introduced at the Miami Grand Prix.
These measures, designed to improve safety and reduce excessive harvesting, were deemed to have delivered improved competition and represent a positive step in the continued refinement of the 2026 framework. The FIA also reported that no material issues or safety concerns had been identified following implementation in Miami. Further evaluation of the Miami package is ongoing with a view to the introduction of further adjustments at future events. These include improved start-safety revisions and measures to improve safety under wet conditions. These will be communicated to teams once defined.
2027 changes
Turning to the longer-term refinement of the regulations, it was agreed in principle to introduce evolutionary changes to the rules regarding hardware components, making competition safer, fairer and more intuitive for drivers and teams. 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.
It was agreed that further detailed discussion in technical groups comprising teams and Power Unit Manufacturers is required before the final package is decided. The final proposals presented during today’s meeting are the result of a series of consultations over the past few weeks between the FIA and multi-stakeholders with input from F1 drivers. The next step is to formally present these regulatory changes, once refined, for a World Motor Sport Council e-vote once the Power Unit Manufacturers voted on the package.
ADUO changes also agreed
Outside this, the FIA also refined the ADUO (Additional Development and Upgrade Opportunities) system for all-new power unit manufacturers, who are uncompetitive and lack reliability when compared to the performers at the front of the F1 2026 field.
While it is not mentioned which manufacturer stands to gain, but considering the lack of performance and reliability from Aston Martin Honda, it is likely that the Japanese manufacturer will be assisted, once the FIA has reviewed and analysed its performance.
F1 calendar changes forces FIA to change review timings of ADUO
Initially, the review was to take place after first six races of F1 2026. But due to the cancellation of Bahrain and Saudi Arabia, the revised calendar for review will be after five, 11 and 18 rounds, respectively – which is after the races in Canada, Hungary and Mexico.
As for the change, the FIA has added another category in ADUO test bench hours. Earlier the cap was 190 hours for any F1 power unit manufacturer which was off eight percent in terms of performance of the leader, as per Article 5.2.7 of the Operational Regulations.
Additional category for test bench hours, Cost Cap allowance
But the change has added another category. The 190 hours will now be granted for power unit which is between eight and 10 percent off the best. And the additional category is for F1 power unit which is more than 10 percent off the best, where it will be awarded 230 hours in the test bench.
This change is also reflected in Cost Cap allowance of the F1 power unit manufacturers under Section E of the regulation. The FIA has changed the same way, by expanding the category. The earlier limit of eight percent is now 8-10 percent category, where extended allowance will be $8,000,000. The new 10% category will see an allowance of $11,000,000 for manufacturer, who are behind.
