“The FIA continues to push forward on innovation and sustainability – across our entire motor sport portfolio – the 2026 Formula 1 Power Unit Regulations are the most high-profile example of that mission,” said FIA president Mohammed Ben Sulayem.
“The introduction of advanced PU technology along with synthetic sustainable fuels aligns with our objective of delivering benefits for road car users and meeting our objective of net zero carbon by 2030. Formula 1 is currently enjoying immense growth and we are confident these regulations will build on the excitement our 2022 changes have produced.”
The FIA has also finalised the new rules around car floors in a bid to curb porpoising. Some voices from the F1 grid, led by Mercedes, continually pushed concerns over drivers’ wellbeing due to the sharp oscillations suffered by a number of teams, lobbying the rule-makers to enforce changes.
Whilst a limit for the amount of bouncing has already been set by the FIA from Belgium onwards, next year car designs will have to adhere to new regulations.
The car floor must be raised by 15mm compared to this year, whilst the diffuser throat height must also be raised with its edges stiffened compared to this season.
There will also be a sensor on the car floor to monitor porpoising.
The FIA has initiated changes to the roll hoop design too, prompted by Zhou Guanyu’s huge accident at Silverstone earlier this year, when the safety device on his Alfa Romeo failed.
Changes in the roll hoop design have been stipulated to stop it digging into the ground, whilst alterations to its safety tests have been as well, to better monitor the loads it can take.
