Formula 1 Undergoes Seismic Transformation: Everything You Need to Know About 2026
The 2026 season marks a watershed moment for Formula 1, introducing sweeping regulatory changes across technical specifications, power units, and the competitive grid itself. With fresh regulations, redesigned machinery, new engine concepts, and the arrival of an 11th team, the sport is entering uncharted territory that will reshape competition as fans know it.
The sport of Formula 1 is preparing for a fundamental reimagining as 2026 approaches. This pivotal year ushers in a completely new rulebook that will touch virtually every aspect of the championship, from the machines competitors will pilot to the engines that power them.
The changes are sweeping in their scope. A novel set of technical regulations will govern car design, while simultaneously, the power unit specifications undergo complete overhaul. Perhaps most significantly, the 2026 grid will feature an 11th team competing alongside the established order, expanding the field and intensifying the battle for supremacy.
BBC Sport has undertaken a comprehensive analysis of these transformative changes, providing fans and stakeholders with a detailed breakdown of what to expect when the new era commences. The modifications represent one of the most substantial regulatory shifts the championship has experienced, promising to reset competitive hierarchies and inject fresh dynamism into the sport at every level.

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 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.
Article C5.1.1
Engine Type
Chapter: C5
In Simple Terms
F1 engines must be traditional 4-stroke engines with pistons that move up and down. This means no rotary engines or other exotic engine types are allowed—only the conventional piston design that's been used in cars for over a century.
- Only 4-stroke engines permitted (intake, compression, combustion, exhaust cycles)
- Must use reciprocating pistons (pistons moving back and forth)
- Rules out rotary engines, 2-stroke engines, and other alternative engine designs
- Ensures all teams compete with the same fundamental engine architecture
Official FIA Text
Only 4-stroke engines with reciprocating pistons are permitted.
