F1 gets FIA approval for 2026 engine regulations

Regulations released almost two months after originally planned date.
  • New engines will be greatly simplified with the removal of the MGU-H
  • Decision paves the way for Porsche and Audi to join F1

The International Automobile Federation (FIA) has ratified Formula One’s updated engine regulations for 2026.

As part of the new regulations, the much-maligned Motor Generator Unit – Heat (MGU-H) has been removed entirely.

This aspect of the engines has always been seen as a stumbling block for potential entrants due to its complex nature, as well as the overall cost of manufacturing.

The regulations are intended to make it far more attractive for new power unit manufacturers to enter the sport. Formula One currently only has four – Ferrari, Mercedes, Renault, and Red Bull Powertrains (supported by Honda).

Now, the simplified engines are relying more heavily on electric power, with the Motor Generator Unit – Kinetic (MGU-K) receiving a 56 per cent increase in available power from 120kW to 350kW.

The new engines are also set to use 100 per cent sustainable fuel, with Formula One recently confirming it will be introduced at the same time as the new engine regulations.

This news is expected to lead to the imminent entries of Porsche and Audi to Formula One, having originally had to delay official announcements in line with the 2026 engine regulations being pushed back.

Porsche will partner with Red Bull Racing with a 50 per cent stake, while Audi has reportedly purchased a 25 per cent stake in the Sauber-owned Alfa Romeo team. Audi is currently looking for an extra 50 per cent to enter the sport.

“The FIA continues to push forward on innovation and sustainability – across our entire motorsport portfolio – the 2026 Formula One power unit regulations are the most high-profile example of that mission,” said Mohammed Ben Sulayem, president of the FIA.

“The introduction of advanced power unit technology along with synthetic sustainable fuels aligns with our objective of delivering benefits for road car users and meeting our objective of net zero carbon by 2030.

“Formula One is currently enjoying immense growth and we are confident these regulations will build on the excitement our 2022 changes have produced.

“I want to thank all of the FIA management and technical staff involved in this process for their diligence and commitment in working together with all of our Formula One stakeholders to deliver this. I also want to thank our World Motorsport Council (WMSC) members for their consideration and approval of these regulations.”
