F1's Most Sweeping Technical Overhaul: A Complete Guide to the New Generation of Machinery

Formula 1 is undergoing its most comprehensive regulatory transformation in the sport's history, with sweeping changes affecting every major component of the car. From revolutionary power units and redesigned chassis to completely new tyre specifications and fuel formulations, the 2026 season will showcase machinery unlike anything seen before on the grid.

F1's Most Sweeping Technical Overhaul: A Complete Guide to the New Generation of Machinery

The world of Formula 1 is bracing for an unprecedented technical revolution. The sport's governing body has implemented the most extensive regulation overhaul in its entire history, reshaping virtually every aspect of the cars competing at the pinnacle of motorsport.

The scope of this transformation is truly remarkable. The power units themselves have been fundamentally reimagined, forcing manufacturers to rethink their approach to propulsion technology. Simultaneously, the structural foundations of the cars—their chassis—have been completely redesigned according to the new technical directives. Beyond these core elements, the specification of tyres gripping the asphalt has been entirely replaced with new compounds and structures, while the very fuel powering these machines has undergone dramatic reformulation.

These interconnected changes represent far more than simple tweaks or seasonal adjustments. Each modification has cascading effects throughout the design philosophy of every team on the grid, requiring engineers and designers to essentially start from scratch in their approach to creating competitive F1 cars.

For fans and observers alike, understanding these changes is essential to appreciating the evolution of the sport and recognizing just how different the racing experience will be when the grid lines up for the start of the new era.

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.

Tyre Specifications

Chapter: Chapter IX - Tyres

In Simple Terms

Pirelli is F1's sole tyre supplier. Each driver gets a fixed allocation per weekend: typically 13 sets of slicks (across soft, medium, hard), plus wet weather tyres. Teams must strategically use their allocation across practice, qualifying, and the race.

  • Pirelli is sole official supplier
  • Fixed allocation per weekend
  • Three dry compounds: soft, medium, hard
  • Intermediate and wet also provided
Official FIA Text

Only tyres supplied by the official tyre supplier may be used. During a race weekend, each driver is allocated a specified number of dry weather tyre sets comprising soft, medium and hard compounds, plus intermediate and wet weather tyres.

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.
