Formula 1's Major Transformation: Understanding What's Different in 2026
The 2026 season marks a pivotal moment for Formula 1 as the sport undergoes comprehensive changes across regulations, machinery, powerplants, and grid composition. With an 11th team joining the grid alongside entirely new technical rules and engine specifications, the championship is entering an unprecedented era. Here's what fans and teams need to know about the sweeping modifications reshaping motorsport's premier category.

The landscape of Formula 1 is undergoing a dramatic overhaul as the sport welcomes 2026 with sweeping regulatory reforms that touch virtually every aspect of competition. From the vehicles competitors will pilot to the power units propelling them around the world's most iconic circuits, virtually nothing remains untouched by this comprehensive restructuring.
The introduction of fresh technical regulations has prompted manufacturers and teams to completely reimagine their approach to machine design. Simultaneously, the power unit specifications have been fundamentally redesigned, requiring engine suppliers and constructor partnerships to develop entirely new concepts. These mechanical and technical evolutions promise to reshape the competitive balance across the grid.
Perhaps most significantly, Formula 1 is expanding its roster with the arrival of an 11th team, a milestone that reflects the sport's continued global appeal and commercial momentum. This addition will bring fresh competition and dynamics to an already intensely contested championship.
BBC Sport has conducted a comprehensive analysis of this transformative period, examining each major change heading into the 2026 campaign and helping stakeholders understand the implications of these modifications on racing strategy, team operations, and competitive outcomes.

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 B8.2.3
Additional Power Unit Units
Chapter: B8
In Simple Terms
In 2026, drivers get one extra Power Unit component for free if their engine manufacturer is brand new to F1 that season. This is a one-time allowance to help new manufacturers get up to speed without penalty concerns.
- New Power Unit manufacturers in 2026 get one additional allocation of each engine component
- This concession only applies to manufacturers in their first year of supplying F1 engines
- The extra unit applies to all Power Unit elements defined in Article B8.2.2
- This is a regulatory allowance, not a penalty relief measure
Official FIA Text
Each driver will be permitted to use an additional unit for each of the Power Unit elements in Article B8.2.2 in the 2026 Championship if the Power Unit is supplied by a PU Manufacturer in its first year of supplying Power Units.
