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 5.1
Definition of a New PU Manufacturer
Chapter: SECTION C: TECHNICAL REGULATIONS
In Simple Terms
A 'New PU Manufacturer' is a company entering F1 for the first time that hasn't built power units before (2014-2021) and hasn't inherited significant technology from existing manufacturers. If approved by the FIA, they receive special benefits and exemptions for 5 years (from 3 years before entry through 1 year after). The FIA evaluates applicants based on their facilities, engine experience, and ERS system knowledge.
- New PU Manufacturers must meet two conditions: no prior homologation since 2014 AND no significant inherited IP from established manufacturers
- Approved new manufacturers receive a 5-year window of special rights/exemptions (N-3 to N+1 calendar years)
- The FIA has absolute discretion in granting status and evaluates applicants on infrastructure investment, ICE experience, and ERS system expertise
Official FIA Text
A PU Manufacturer intending to supply PUs for the first time in year N, will be considered to be a "New PU Manufacturer" if it (or any related party): a. has not homologated a PU at least once in the period 2014-2021; and b. has not received any significant recent Intellectual Property from a PU Manufacturer who is not a New PU Manufacturer, subject to the conditions outlined in Article 5.2 of this Appendix. (together, for this Article 5 only, the "Necessary Conditions") The "New PU Manufacturer" status will be granted by the FIA, at its absolute discretion, for the complete calendar years from N-3 to N+1. In order to be granted the "New PU Manufacturer" status, the PU Manufacturer in question must, upon the request of the FIA, provide the FIA with all of the detailed information or documents requested by the FIA describing the commercial background and details of the PU Manufacturer's business, the Intellectual Property owned by the PU Manufacturer and the technical relationship between the PU Manufacturer and any other related entity or persons (the "Requested Documentation"). PU Manufacturers granted a "New PU Manufacturer" status are given additional rights or exemptions in certain provisions of the Technical, Sporting and Financial Regulations. In order to assess whether the Necessary Conditions have been satisfied by a PU Manufacturer, the FIA will assess the Requested Documentation provided by the PU Manufacturer with regard to three factors: a. Infrastructure: the necessity for the PU Manufacturer to build facilities, invest significantly in assets, and hire personnel with prior Formula 1 experience; b. ICE status: the prior experience of the PU Manufacturer in Formula 1 Internal Combustion Engines, and potential possession of significant recent Intellectual Property; and c. ERS status: the prior experience of the PU Manufacturer in Formula 1 ERS systems, and potential possession of significant recent Intellectual Property.
