With the next generation of engine regulations to begin at the start of the 2026 season, Formula One has revealed that six engine suppliers have already jumped on board. And, with only four suppliers at present in 2023, the jump to six, in 2026, may make things that more interesting.
So what's new for F1 power-trains from 2026? Well, the main upcoming change for engines will be their sustainability; making them more "environmentally-friendly" and more "cost-friendly" to the teams and suppliers who will build them.
The most recent engine, the 1.6 litre V6, was first introduced for the 2014 season and, although it is to be retained for 2026 on-wards, the output of electrical power will be increased to 350kW. This change also sees the removal of the complex MHU-H system and the addition of an engine cost cap, both of which could be the prevalent reasons as to why more engine manufactures have come forward for the 2026 season. As of 3rd February, six suppliers have been confirmed to have completed their registrations.
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 six engine suppliers currently registered for 2026 are Alpine Racing, Audi, Ferrari, Honda Racing Corporation, Merecedes-AMG and Red Bull Ford. At the start of 2023, only Ferrari, Honda and Mercedes will appear in the upcoming season with Alpine using Renault powertrains. In 2026, Audi will join forces with Sauber whereas Ford will partner with Red Bull once they split from Honda at the end of 2025. It is not yet known who Honda will be supplying engines to from 2026. It should be noted that Porsche was also in negotiation to become an engine supplier for 2026. However, talks broke down over the summer months in 2022.
The signing of six engine manufacturers comes at a time when F1 is experiencing a boom in popularity and could, potentially, plant the seed or open the door to further engine supplier entrants in the future. Until then, we look forward to what awaits us in 2026.
