F1: FIA Confirms 2026 Formula 1 Power Unit Supplier Registrations

The FIA today confirmed that at least six manufacturers have registered as Power Unit Suppliers for the 2026-2030 seasons of the FIA Formula One World Championship onwards. These are:

  • Alpine Racing
  • Audi
  • Ferrari S.p.A.
  • Honda Racing Corporation
  • Mercedes-AMG High-Performance Powertrains Ltd.
  • Red Bull Ford

Our Opinion: More can still join. We expect Cadillac will join with either Honda, Renault or Ilmor

We expect Porsche to also join in some capacity

There’s no commitment to compete if you’ve registered, and if you want to compete you can still register later. Therefore, a nebulous list in our opinion.

These companies will supply the next generation of Formula 1 Power Unit set out in the 2026 FIA Formula 1 Sporting and Technical PU regulations that are published on the FIA website.

FIA President Mohammed Ben Sulayem said: The confirmation that there will be six Power Unit manufacturers competing in Formula 1 from 2026 is testament to the strength of the championship and the robust technical regulations that have been diligently created by the FIA in close collaboration with Formula 1 and the Power Unit manufacturers. The Power Unit is at the forefront of technological innovation, making the future of Formula 1 more sustainable while maintaining the spectacular racing. I am grateful for the confidence of world-leading automotive manufacturers demonstrated by their commitment to Formula 1.”

The six registrants will participate in the FIA Formula One World Championship seasons 2026-2030 under the technical regulations approved by the FIA Formula 1 Commission and World Motor Sport Council in August of this year.

The key pillars of the 2026 framework are:

  • Maintaining the spectacle – the 2026 Power Unit will have similar performance to the current designs, utilizing high-power, high-revving V6 internal combustion engines and avoiding excessive performance differentiation to allow for improved raceability.
  • Environmental sustainability – the 2026 Power Unit will include an increase in the deployment of electrical power close to 50% and utilize a 100% sustainable fuel.
  • Financial Sustainability – Financial Regulations regarding the Power Units will reduce the overall costs for competitors whilst retaining the cutting-edge technological showcase that is at the core of Formula 1.

A detailed overview of the key elements of each section of the Power Unit Regulations can be found below:

2026 Formula 1 Power Unit

PU Technical Regulations


Fully sustainable fuel is a cornerstone of the 2026 regulations and all fuel components must come from sustainable sources – either non-food-bio-derived, from genuine municipal waste or from sustainable carbon capture. This ensures that no new fossil carbon will be in the fuels used in Formula 1 and therefore no new fossil carbon will enter the atmosphere from a Formula 1 car exhaust.

Fuel regulations encourage any sustainable production method to be followed without prejudicing on-track performance so fuel suppliers can use Formula 1 as a step in their own pathway to global and commercial scaling up of sustainable technology.

  • All fuel constituents must be fully sustainable.
  • The overall greenhouse gas saving will be in line and stay in line with latest European standards as they evolve.
  • Fuel flow rate to the ICE will be limited by energy, not mass or volume.
  • More parameters will be limited to ensure the fuel developed is a relevant, drop-in gasoline that will be competitive whichever production method is produced.

Internal Combustion Engine (ICE)

The ICE will retain the V6, 1.6-litre layout at the same RPM, with a reduced fuel flow rate to aim for a power output of approximately 400kW. The ICE will be broadly split in two parts:

  • The lower part, involving the engine block, crankshaft, connecting rods, pumps, and ancillaries which will be more prescribed.
  • The upper part, mainly focused on the combustion area and the associated components will also feature prescription but there will be more freedom to develop the combustion system for the new fuel.

The objective is for ICE competition to focus primarily on the upper part, with the lower part being more prescribed dimensionally, and having longer homologation periods.

A range of standardization and simplification measures has been developed across the whole ICE to achieve a cost reduction.

  • The MGUH will be removed.
  • Variable trumpets and their actuation and control systems will be removed.
  • Limited ranges to key dimensions are defined (for example piston, crank, block, valves, injector position, turbocharger wheels).
  • Overall PU element legality volumes are now more precisely defined.
  • Material limitations have been extended to exclude many high-cost options.
  • Extension of standardization of components or of their design features (injector, knock

    sensor, ignition coils, ‘powerbox’, torque/temperature/pressure sensors).

  • The supply perimeter has been extended to ensure parts such as exhaust systems and ancillaries must be designed for a complete PU life resulting in a significant cost saving over a season. An upgrade and homologation schedule has been defined to control development and changes of specification between years.

Energy Recovery System (ERS)

The ERS will be increased in power to 350kW. This will remain a key area of competition between the PU Manufacturers, with an emphasis on energy flow management to achieve the key objectives of spectacle, increased hybridization and similar overall performance to the current PU.

  • Regulations will aim to increase the road-relevance of the cells, power electronics and MGUK.
  • Cells will be an area of development, but their supply will have non-exclusivity provisions to contain a potential cost escalation.
  • Design constraints to improve ERS safety and the ability to police have been mandated.
  • Controls have been introduced that either limit or require recycling of critical materials.

Overall PU Layout

The positioning of key PU components is more restrictive in the 2026 PU Regulations in order to not lock in long-term advantages or disadvantages. A range of reference volumes has been defined within which each PU element must lie.

PU Sporting Regulations

PU Usage

In each year, each driver will be able to use:

  • 3x ICE / turbocharger / exhaust units.
  • 2x Energy stores / MGUKs.

For the first year of these new regulations (2026), these numbers will be increased by one.

PU Test Bench Restrictions

For cost control reasons, clear definitions are given to the various PU Test Benches that can be used by a PU Manufacturer for the development of their PUs. The potential PU Test Benches (and the maximum number each PU Manufacturer may use) are:

  • Single-Cylinder Dynamometers: 3
  • Power Unit Dynamometers: 3
  • Power Train Dynamometer: 1
  • Full Car Dynamometer: 1
  • ERS Test Benches: 2

The number of operational hours that PU Manufacturers can use for their development is limited to control costs, according to the following table:

Operation hrs / year










2026 PU

limit – ICE


5400 (over 3 years)






2026 PU

limit – ERS


3400 (over 3 years)






PU Financial Regulations
