The decisions were made during the World Motor Sport Council meeting in Macau, where officials reviewed changes across several FIA championships.
In Formula 1, the focus was on improving safety, clarity and the future direction of the sport.
One key adjustment for 2026 concerns heat-related risks. The FIA confirmed that a heat hazard declaration can now be made separately for a Sprint event and the main Grand Prix, although the decision must still be announced at least 24 hours before the scheduled start time.
The governing body also made changes to power management in difficult conditions. When races take place in wet weather or poor visibility, boost mode will return as a safety measure. However, it will only prevent cars from losing performance and will not provide extra power. Overtake mode will also be unavailable in those conditions.
Attention has already turned towards the next generation of regulations, with the FIA approving the first draft of the 2027 technical rules. The updates are designed to improve consistency and make the regulations easier for teams to follow, while also using lessons learned from the 2026 season.
The FIA also confirmed future changes to Formula 1 power units. From 2028, engines will move towards a 60:40 split between internal combustion power and battery energy, replacing the 50:50 balance planned for 2026. The changes will include adjustments to engine output, fuel energy flow and energy recovery systems, giving teams more flexibility in managing power.
FIA president Mohammed Ben Sulayem said the organisation would continue working with teams, drivers and fans as Formula 1 evolves.
“Continuous dialogue and collaboration are essential to ensuring that the regulations meet the needs of the sport, its drivers, and its fans,” Ben Sulayem said.
The FIA also highlighted ongoing discussions about future engine concepts, including the possibility of bringing back V8 engines powered by sustainable fuels as Formula 1 looks ahead to the next era of competition.
The 2026 Formula 1 season continues with the Austrian Grand Prix from June 26 to June 28 at the Red Bull Ring in Spielberg, Austria.
