FIA Signals Regulatory Reassessment: Energy Rules Under Review Following Shanghai
The FIA has committed to examining Formula 1's contentious energy management regulations in the wake of the Chinese Grand Prix. Nikolas Tombazis, who oversees single-seater competition for the governing body, has publicly confirmed that a comprehensive review of the rules is on the agenda.
Formula 1's regulatory framework governing energy management has drawn considerable scrutiny this season, prompting the FIA to take action. Nikolas Tombazis, the FIA's single seater director, has announced that the championship will conduct a formal review of these disputed regulations following the conclusion of the Chinese Grand Prix.
The energy management rules, which have proven to be a point of contention within the sport, will now face scrutiny from the sport's governing body. This review represents an acknowledgment of the ongoing discussions and concerns that have emerged around how teams manage their power units throughout races.
The decision to conduct this examination after Shanghai suggests the FIA is taking feedback seriously and remains open to potential adjustments to the regulatory framework. Whether this review will lead to modifications or serve as confirmation that the current system is functioning as intended remains to be seen, but the move signals the FIA's commitment to ensuring fair competition and stakeholder satisfaction in the 2026 season.

Full Regulation Text
Article C5.2.3
Fuel Energy Flow Maximum
Chapter: C5
In Simple Terms
F1 cars have a limit on how much energy they can get from their fuel per hour of racing. This rule ensures all teams use fuel efficiently and prevents any team from gaining an unfair power advantage by burning fuel faster than allowed. The maximum allowed rate is 3000 megajoules per hour.
- Fuel energy flow is capped at 3000MJ/h to promote fair competition
- This regulation encourages efficient fuel consumption and energy management
- Teams must monitor and control their fuel burn rate throughout the race
- Exceeding this limit is a technical regulation breach with sporting penalties
Official FIA Text
Fuel energy flow must not exceed 3000MJ/h.
Article C5.2.4
Fuel Energy Flow Below 10500rpm
Chapter: C5
In Simple Terms
F1 engines must limit how much fuel energy they use at lower engine speeds (below 10,500 rpm). The rule uses a formula to calculate the maximum allowed energy flow: teams can use more energy as the engine spins faster, but they're strictly limited to prevent excessive power at lower rpms.
- Applies only when engine speed is below 10,500 rpm
- Energy flow limit increases with engine rpm using the formula: 0.27 × rpm + 165 MJ/h
- At 10,500 rpm, the limit reaches approximately 2,997 MJ/h
- Ensures fair competition and controls engine performance in the low-rpm range
Official FIA Text
Below 10500rpm fuel energy flow must not exceed EF(MJ/h)=0.27*N(rpm)+165.
Article C5.2.9
Energy Storage State of Charge Range
Chapter: C5
In Simple Terms
The energy storage system (ES) in F1 cars must maintain a relatively narrow operating window while racing. The difference between when the battery is most charged and least charged cannot exceed 4 megajoules at any point the car is on track. This rule ensures fair competition by preventing teams from using an unrestricted battery range.
- Energy storage can fluctuate by a maximum of 4MJ between its highest and lowest charge states during racing
- This limitation applies whenever the car is on track, including practice sessions and races
- The rule prevents teams from gaining unfair advantages through unrestricted battery management strategies
- Teams must carefully calibrate their energy recovery and deployment systems to stay within this window
Official FIA Text
Difference between maximum and minimum state of charge of ES may not exceed 4MJ at any time car is on track.
