Alonso Blasts 2026 Rule Changes as "Battery World Championship"
Fernando Alonso has voiced strong criticism of the 2026 regulations now governing Formula 1, expressing his dissatisfaction with the direction the sport has taken. The Aston Martin driver's comments highlight growing concerns about the new technical framework implemented this season.
The new technical regulations introduced to Formula 1 for the 2026 season have found a vocal critic in Aston Martin's Fernando Alonso, who has made little effort to hide his frustration with the sweeping changes.
Alonso's pointed remarks characterizing the sport as a "battery world championship" underscore his skepticism about the regulatory direction taken by the FIA. The Spanish driver's candid assessment reflects deeper concerns about how the 2026 regulations have reshaped the fundamental nature of competitive racing.
With the sport having embarked on this new regulatory era, Alonso's perspective serves as a reminder that not all participants have embraced the changes with enthusiasm. His comments suggest that while the sport's decision-makers pursued these modifications with specific objectives in mind, the transition has created tension within the paddock regarding how F1 should evolve moving forward.

Article 2.2
2026 Power Unit Regulations
Chapter: Chapter II - Power Unit Changes
In Simple Terms
2026 brings major engine rule changes. The complex MGU-H is removed to cut costs and attract new manufacturers. To compensate, the MGU-K becomes much more powerful and the battery is bigger. The goal is simpler, more sustainable power units that are still cutting-edge.
- MGU-H removed from power units
- MGU-K power increased significantly
- Larger energy store capacity
- Aims to attract new manufacturers
Official FIA Text
For 2026, the power unit will comprise a 1.6 litre V6 turbocharged internal combustion engine with a significantly enhanced electrical component. The MGU-H will be removed. The electrical power output will increase substantially with a more powerful MGU-K and larger energy store.
Article C5.2.7
ERS-K Absolute Electrical Power
Chapter: C5
In Simple Terms
The ERS-K (kinetic energy recovery system) is the hybrid power unit that harvests energy from braking. F1 regulations cap the maximum electrical power this system can produce at 350kW to maintain competitive balance and prevent any team from gaining an unfair advantage through excessive hybrid power.
- ERS-K electrical power output is strictly limited to a maximum of 350kW
- This applies to the absolute DC electrical power measurement of the kinetic energy recovery system
- The limit ensures all teams operate within equal technical parameters for the hybrid system
- Exceeding this power threshold would constitute a technical regulation breach
Official FIA Text
Absolute electrical DC power of ERS-K may not exceed 350kW.
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.
