After what feels like an age since discussions began, the FIA has finally ratified the engine regulations for the next era of the FIA Formula 1 World Championship, starting in 2026.
The current V6, 1.6-litre layout will remain with the same RPM levels, however the MGU-H element will be removed, while the fuel flow rate will also be reduced with an aim of a power output of around 400kW.
There will also be a lot of ‘standardisation’ and ‘simplification’ measures implemented, including the removal of variable trumpets and their actuation and control systems, as well as the extension of standardising of certain components and/or their design features. This includes the likes of injectors, knock sensors, ignition coils and some sensors such as torque, temperature and pressure sensors.
As well as these changes, the exhaust systems and ancillaries must be designed to extend to a full Power Unit life, saving teams a significant amount of money in the process.
Fully sustainable fuel will also be introduced, meaning the end of fossil fuels within Formula 1, with the futures fuels coming from either, non-food-bio derived, genuine municipal waste or sustainable carbon captures.
