F1 and FIA Set to Cast Votes on Disputed Engine Specification Linked to Mercedes Innovation
Formula 1 officials and the FIA are preparing to hold a vote concerning a mid-season prohibition on a contentious engine configuration that Mercedes is credited with developing. The proposed ban would take effect during the 2026 season.
The sport's governing authorities and Formula 1 leadership are set to make a decisive ruling on whether to implement a mid-season restriction targeting a disputed engine design credited to Mercedes ahead of the 2026 season.
The proposal centers on prohibiting the controversial power unit specification through a mid-season intervention, addressing what has become a significant technical debate within the paddock. Mercedes has been identified as the team behind the development of this particular engine design, which has drawn scrutiny and debate among competitors and officials alike.
The voting process will determine whether the FIA and Formula 1 proceed with enforcing the ban during the 2026 campaign, marking a potential turning point in how technical regulations are managed mid-championship. This decision carries implications not only for Mercedes but for the broader competitive landscape as teams prepare their power unit strategies for the upcoming season.

Full Regulation Text
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 C1.6
New systems or technologies
Chapter: ARTICLE C1: GENERAL PRINCIPLES
In Simple Terms
If a team invents a clever new system or technology that isn't explicitly mentioned in the rulebook but the FIA approves it, they can only use it for the rest of that season. Once the season ends, that innovation is no longer allowed unless it becomes an official part of the regulations.
- New technologies must be approved by the FIA before use
- Approved innovations are only permitted until the end of the season in which they're introduced
- Teams cannot carry over one-season innovations to the next season automatically
- The regulation prevents any team from gaining a permanent advantage from a loophole
Official FIA Text
Any new system, procedure or technology not specifically covered by these Technical Regulations, but which is deemed permissible by the FIA, will only be admitted until the end of the Championship during which it is introduced.
Article 5
Conformity with the power unit homologation dossier
Chapter: APPENDIX C5: HOMOLOGATION AND DEVELOPMENT OF POWER UNITS, FUEL AND OIL FOR 2026-2030
In Simple Terms
F1 engines must be built in a way that allows the FIA to put official seals on them for inspection. The engine manufacturer and teams using that engine must prove to the FIA at any time that their engine matches the original approved design specification.
- Power units must be designed to allow FIA seals to be fitted for verification purposes
- Both engine manufacturers and teams must cooperate fully with FIA technical inspections
- Teams must demonstrate engine conformity with the homologation dossier whenever the FIA requests it
- The FIA has absolute discretion to demand compliance checks at any competition
Official FIA Text
All Power Units must be delivered such that the seals required under Article B8.2.9 can be fitted. Both the Power Unit Manufacturer and users of a homologated Power Unit must take whatever steps are required at any time by the FIA Technical Department, in its absolute discretion, to demonstrate that a Power Unit used at a Competition is in conformity with the corresponding Power Unit homologation dossier.
