FIA approves 60-40 power split for F1 engines from 2028
The agreement on the power distribution of Formula 1 power units for the 2027 and 2028 seasons was reached two weeks ago, and today it received final approval from the FIA after ratification by the World Motor Sport Council during its meeting in Macau.
The final step has now been completed regarding the widely discussed compromise between internal combustion and electric power. The FIA has officially confirmed that the 60-40 balance, corresponding to 450 kW from the combustion engine and 300 kW from the electrical system, will be postponed until 2028.
As early as 2027, however, the share of power generated by the internal combustion engine will increase to 58 percent of the total output, reaching 420 kW, while the electrical contribution will be reduced to 42 percent, or 300 kW. The current distribution stands at 53-47, equivalent to 400 kW from the combustion engine and 350 kW from the electrical system.
Starting next season, fuel flow will increase by five percent, ahead of the planned 13 percent increase set for 2028. To compensate for the higher fuel consumption without forcing teams to redesign their fuel tanks, selected Grands Prix could feature slightly shorter race distances and reduced formation laps.
Mohammed Ben Sulayem comments on the future direction of Formula 1
“The FIA continues to oversee the evolution of the 2026 regulations and to work closely with all key stakeholders across the motorsport community,” said FIA President Mohammed Ben Sulayem.
“As with any major regulatory change, the process does not end when the cars first take to the track. Ongoing dialogue and collaboration are essential to ensure that the regulations meet the needs of the sport, the drivers and the fans.
“Together, we are exploring the future direction of the championship and assessing how the sport can balance innovation, sustainability, performance and fan appeal in the years ahead.
“Discussions regarding future powertrain concepts, including V8 engines powered by sustainable fuels, demonstrate the willingness of all parties involved to help shape the next chapter of this sport.”
Additional FIA rule changes confirmed
The FIA has also introduced several other regulatory updates. One of the most immediate changes concerns the Heat Hazard protocol, which was created to protect drivers during periods of extreme temperatures.
The procedure will now be activated whenever weather forecasts predict temperatures of at least 31 degrees Celsius during a race weekend. The FIA has clarified that the alert can be applied separately to a Sprint event, a Grand Prix, or both sessions, with official notification to be issued 24 hours before the relevant event.
On the safety front, boost mode will be reintroduced for low-grip conditions such as heavy rain or reduced visibility. The measure is designed to prevent sudden power losses from the cars in difficult conditions, while the overtaking function will be disabled during those situations.
Finally, the FIA has confirmed an increase in pre-season testing ahead of the 2027 Formula 1 campaign. Teams will have four days of winter testing instead of the current three, giving manufacturers additional time to prepare for the evolving technical regulations.
