Following prolonged discussions, the FIA has agreed on the power unit rules with the six Power Unit Providers set to participate in Formula One between 2026 and 2030.
As was written within the stars the MGU-H will probably be faraway from the power items. The system was launched in 2014 as a way to get rid of lag on the reintroduced turbo whereas enabling power items to get better power from the exhaust gases. Though highly effective, the system proved sophisticated and expensive, resulting in lengthy lasting issues for Renault in 2014 and notably additionally for Honda who endured appreciable issues to get on prime of their issues.
Hence, in an effort to make power unit growth more value environment friendly, the MGU-H will probably be “replaced” by a more highly effective MGU-Ok, a system that recovered and provides power to the driveshaft through {an electrical} motor.
The FIA at this time confirmed that Alpine Racing, Audi, Ferrari S.p.A., Honda Racing Corporation, Mercedes-AMG High Performance Powertrains Ltd. and Red Bull Ford have registered as Power Unit Suppliers for the 2026-2030 seasons of the FIA Formula One World Championship onwards.
These firms will provide the subsequent era of Formula 1 Power Unit set out within the 2026 FIA Formula 1 Sporting and Technical PU rules.
FIA President Mohammed Ben Sulayem stated: “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.”
Fuel
Fully sustainable gasoline is a cornerstone of the 2026 rules and all gasoline parts should come from sustainable sources – both non-food-bio-derived, from real municipal waste or from sustainable carbon seize. This ensures that no new fossil carbon will probably be within the fuels utilized in Formula 1 and due to this fact no new fossil carbon will enter the ambiance from a Formula 1 automobile exhaust.
Fuel rules encourage any sustainable manufacturing technique to be adopted with out prejudicing on-track efficiency so gasoline suppliers can use Formula 1 as a step in their very own pathway to world and industrial scaling up of sustainable expertise.
– All gasoline constituents have to be totally sustainable.
– The general greenhouse fuel saving will probably be in line and keep in keeping with newest European requirements as they evolve.
– Fuel circulation fee to the ICE will probably be restricted by power, not mass or quantity.
– More parameters will probably be restricted to make sure the gasoline developed is a related, drop-in gasoline that will probably be aggressive whichever manufacturing technique is produced.
Internal Combustion Engine (ICE)
The ICE will retain the V6, 1.6-litre format on the identical RPM, with a lowered gasoline circulation fee to purpose for a power output of roughly 400kW. The ICE will probably be broadly cut up in two elements:
– The decrease half, involving the engine block, crankshaft, connecting rods, pumps, and ancillaries which will probably be more prescribed.
– The higher half, primarily centered on the combustion space and the related parts may also characteristic prescription however there will probably be more freedom to develop the combustion system for the brand new gasoline.
The goal is for ICE competitors to focus primarily on the higher half, with the decrease half being more prescribed dimensionally, and having longer homologation intervals.
A spread of standardisation and simplification measures has been developed throughout the entire ICE to attain a price discount.
– The MGUH will probably be eliminated.
– Variable trumpets and their actuation and management methods will probably be eliminated.
– Limited ranges to key dimensions are outlined (for instance piston, crank, block, valves, injector place, turbocharger wheels).
– Overall PU component legality volumes are actually more exactly outlined.
– Material limitations have been prolonged to exclude many high-cost choices.
– Extension of standardisation of parts or of their design options (injector, knock sensor, ignition coils, ‘powerbox’, torque/temperature/strain sensors).
– The provide perimeter has been prolonged to make sure elements resembling exhaust methods and ancillaries have to be designed for an entire PU life leading to a big value saving over a season. An improve and homologation schedule has been outlined to manage growth and modifications of specification between years.
Energy Recovery System (ERS)
The ERS will probably be elevated in power to 350kW. This will stay a key space of competitors between the PU Manufacturers, with an emphasis on power circulation administration to attain the important thing targets of spectacle, elevated hybridisation and comparable general efficiency to the present PU.
– Regulations will purpose to extend the road-relevance of the cells, power electronics and MGUK.
– Cells will probably be an space of growth, however their provide may have non-exclusivity provisions to comprise a possible value escalation.
– Design constraints to enhance ERS security and the flexibility to police have been mandated.
– Controls have been launched that both restrict or require recycling of essential supplies.
Overall PU Layout
The positioning of key PU parts is more restrictive within the 2026 PU Regulations with a purpose to not lock in long-term benefits or disadvantages. A spread of reference volumes has been outlined inside which every PU component should lie.
PU Sporting Regulations
PU Usage
In every year, every driver will be capable to use:
– 3x ICE / turbocharger / exhaust items.
– 2x Energy shops / MGUKs.
For the primary yr of those new rules (2026), these numbers will probably be elevated by one.
PU Test Bench Restrictions
For value management causes, clear definitions are given to the varied PU Test Benches that can be utilized by a PU Manufacturer for the event of their PUs. The potential PU Test Benches (and the utmost quantity every PU Manufacturer could use) are:
– Single-Cylinder Dynamometers: 3
– Power Unit Dynamometers: 3
– Power Train Dynamometer: 1
– Full Car Dynamometer: 1
– ERS Test Benches: 2
The variety of operational hours that PU Manufacturers can use for his or her growth is proscribed to manage prices, in accordance with the next desk:
PU Financial Regulations
The FIA 2026 F1 Power Unit Financial Regulations have been developed by FIA with the help of Deloitte LLP. Deloitte LLP has issued a Certification Report to substantiate that the proposed FIA 2026 F1 Power Unit Financial Regulations are match for function to attain the targets illustrated under.
Objectives and Cost Cap Level
Regulations to come back into from 1 January 2023 to assist obtain the next targets:
– To promote the long-term aggressive stability of the championship in respect of PUs.
– To promote the long-term sporting equity of the championship in respect of PUs.
– To make sure the long-term monetary stability and sustainability of the PU Manufacturers, whereas preserving the distinctive expertise and engineering problem of Formula 1.
