The compression ratio clarification wasn’t the only one issued by the FIA. For some time now, F1 has used ultrasonic fuel flow meters as a way to control power outputs. Under the outgoing regulations, this was capped at 100 kg/h, but with the move to fully sustainable synthetic fuels, this is changing to an energy cap of 3,000 MJ/h instead.

Ferrari's 'revolutionary' engine has been approved ahead of the launch of Project 678 for Lewis Hamilton and Charles Leclerc in F1 2026.

Pre-season testing hasn't got underway yet and already controversy over Mercedes' power unit threatens to throw the opening races of the 2026 season into chaos.

Formula 1’s 2026 race car introduces major technical changes, including updated hybrid power units, increased electrical energy use, active aerodynamics replacing DRS, and smaller, lighter chassis. The new rules aim to improve racing,

The 2026 F1 season hasn't started yet, but there's already a major controversy brewing surrounding engines in cars being driven by Mercedes and Red Bull.

Ford says it is contributing more to Red Bull’s new Formula 1 engines than originally discussed, which is linked to the Blue Oval’s changing road car strategy

F1 cars are fast, thanks to their continuous focus on achieving the lowest possible lap times. They do this by fine-tuning their race cars' engines, tires, and aerodynamics, while working within a fixed package of rules that must be followed to the letter.

Modern Formula 1 power units turn a brutally strict rulebook into a physics experiment that borders on science fiction. With tiny 1.6‑liter engines, capped fuel flow and tight component limits, teams are still extracting well over 1,
