System One Finalizes 2026 Engine Guidelines – Extra Electrons, Fewer Molecules (With Video)

After what looks like years of wrangling, the FIA has introduced new technical guidelines that may govern the powertrains utilized by System One groups starting with the 2026 season. On the heart of the discussions concerning the new guidelines is the will to draw new engine suppliers to the game. At the moment, if you wish to race in System One, you must selected an engine provided by Ferrari, Mercedes, Renault, or Honda/Pink Bull.

Volkswagen Group has been pondering of getting in on the enjoyable for a number of years, however it’s a automobile firm and a mass manufacturing automobile firm at that. There may be an previous expression in racing that claims, “Win on Sunday, promote on Monday.” Whereas that phrase originated in NASCAR, it explains why Volkswagen isn’t excited by getting concerned with System One except the engine know-how is related to its manufacturing vehicles.

In System One right now, the vast majority of groups are owned by automobile firms — Alfa Romeo, Ferrari, Mercedes, McLaren, Aston Martin, or Alpine (Renault). Solely Pink Bull, Williams, Haas, and Alpha Tauri (the Pink Bull B crew) aren’t concerned in vehicle manufacturing. The brand new guidelines have been crafted particularly to fulfill Volkswagen Group, which can now see two of its manufacturers — Porsche and Audi — be part of the game as engine suppliers in 2026.

Charting The System One Engine Adjustments

In a press launch final week saying the brand new 2026 engine laws, FIA President Mohammed Ben Sulayem mentioned, “The FIA continues to push ahead on innovation and sustainability — throughout our complete motor sport portfolio — the 2026 System 1 Energy Unit Rules are essentially the most high-profile instance of that mission. The introduction of superior PU know-how together with artificial sustainable fuels aligns with our goal of delivering advantages for highway automobile customers and assembly our goal of internet zero carbon by 2030. System 1 is at present having fun with immense development and we’re assured these Rules will construct on the thrill our 2022 modifications have produced.”

The brand new laws are supposed to assist the 4 major long run targets for System One:

  • Sustaining the spectacle — the 2026 Energy Unit can have comparable efficiency to the present designs, using excessive energy, excessive revving V6 inside combustion engines and avoiding extreme efficiency differentiation to permit for improved raceability.
  • Environmental sustainability — the 2026 Energy Unit will embody a rise within the deployment {of electrical} energy to as much as 50% and make the most of a 100% sustainable gasoline.
  • Monetary Sustainability — Monetary Rules concerning the Energy Items will scale back the general prices for opponents while retaining the leading edge technological showcase that’s on the core of System 1.
  • Engaging to new Energy Unit Producers — the laws are supposed to make it potential and engaging for newcomers to hitch the game at a aggressive degree.

Gone from the brand new powertrains would be the MGU-H, a tool that harvested electrical energy from engine warmth and used it to energy an electrical motor that in flip might spool up the turbocharger impartial of the move of exhaust gases. This system allowed the vehicles to keep away from the lag time related to turbochargers when the engines had been working at low speeds.

However the items had been extremely complicated and sophisticated engine packaging significantly. In the beginning of the turbo hybrid period in 2014, the turbocharger and the MGU-H had been bundled collectively and failure charges had been excessive. Mercedes solved the packaging drawback by splitting the MGU-H in half and positioning the elements at both finish of the engine. They had been related by a shaft operating between the cylinder heads of the V-6 engine. Failure charges plummeted and it took most opponents years to catch up.

Turbochargers in highway vehicles are largely a results of System One’s resolution to make use of turbocharged engines within the Eighties. However the MGU-H know-how has little relevance to passenger vehicles and so producers like Volkswagen have been reluctant to hitch the game. Now the MGU-H is gone and Volkswagen Group is in. That’s no coincidence.

The brand new guidelines tightly regulate the decrease finish of the engines — the block, crankshaft, and pistons. In addition they eradicate variable size air intakes and different gimmicks that develop the ability vary of the engines. However they depart engine suppliers extra freedom to experiment with the cylinder heads, which appeals to the businesses. In addition they encourage improvements within the batteries and electrical motors which are included into the hybrid powertrains. That’s an space that’s extremely related to firms like Volkswagen which are concentrating extra on making electrical automobiles and fewer on vehicles and vans with inside combustion engines.

The brand new guidelines elevate the full energy obtainable from the electrical motor from 120 kW (160 hp) in right now’s vehicles to 350 kW (470 hp). The engines will run on 100% sustainable fuels sourced from non-food vegetation, municipal waste, or carbon seize, which means no new carbon dioxide will likely be added to the ambiance by the engines. Output of the turbocharged 1.6 liter engine will stay at about 635 kW (850 hp).

At the moment, System One establishes a most gasoline move charge, however the brand new guidelines will mandate a most power move charge as a substitute. At the moment’s vehicles are allowed 100 kilograms of gasoline for a race, however the brand new engine components will restrict them to not more than 80 kilograms of gasoline, which can place a premium on methods that maximize the quantity {of electrical} power harvested throughout a race.

The Takeaway

Through the years, engine producers have come and gone from System One. Honda, Toyota, and Ford have gotten closely concerned at one time or one other. All stop the game when prices accelerated past expectations and/or outcomes on the observe lagged behind projections. Honda jumped again in to grow to be the engine provider for Pink Bull a couple of years in the past, however then backed out once more, though it agreed to proceed working with Pink Bull Know-how, which now provides the ability items for its race vehicles. Porsche has now jumped into the System One recreation through Pink Bull Know-how, in response to Mark Hughes of The Race.

Audi has cast a relationship with the Alfa Romeo/Sauber crew and reportedly will grow to be its engine provider in 2026, though whether or not it’s going to nonetheless be referred to as Alfa Romeo at that time is unclear. Why would Audi and Porsche be concerned with groups that compete in opposition to one another? As a result of racing improves the breed. Finally, something one Volkswagen Group division is aware of filters by means of the group to all the opposite divisions. Audi and Porsche additionally compete inside the Group, with every growing its personal electrical automobile chassis.

System One is massively well-liked worldwide, which makes it a dream venue for advertising and marketing departments. There was a time when the game was dominated by people like Bruce McLaren, Dan Gurney, Colin Chapman, and Enzo Ferrari — individuals who offered vehicles to assist their racing actions. Now these racing actions assist the sale of vehicles.

None of this addresses the huge carbon footprint of System One which flies around the globe to races some 24 or extra occasions a 12 months, or the carbon emissions of all of the vehicles followers drive to these races. However that critique will be leveled in opposition to each sporting occasion on the planet. System One is making a valiant effort to stay related whereas not killing the goose that laid the golden egg. Judging by its tens of millions of avid followers, no matter it’s doing is working simply nice.
