While the headline battle over Formula 1's 2027 engine rules remains stuck in the mud, the sport's decision-makers did push through a series of concrete changes at the latest F1 Commission meeting - chief among them a longer pre-season test.
The Commission confirmed that winter testing for 2027 will be expanded from three days to four, giving teams an extra day to prepare for what is shaping up to be a significant technical reset. The venue has not been finalised, though Bahrain remains the most likely host based on recent precedent.
The extra mileage is a direct response to the scale of change coming in 2027, and to the concern that teams could arrive at the first race underprepared if the new power units and chassis packages are bedded in across just three days.
There was also notable support among team principals for shortening some grands prix by a handful of laps, alongside a proposal to limit drivers to a single reconnaissance lap on their way to the grid. The logic is practical rather than sporting: trimming race distance and warm-up running would reduce the fuel a car must carry, helping teams avoid larger fuel tanks that could otherwise force expensive chassis redesigns under the 2027 rules.
The Commission also tightened the regulations around Testing of Previous Cars. Such sessions will now be restricted at circuits due to host a grand prix in the near future, closing a loophole and keeping the format focused on its intended purpose of giving young drivers additional mileage rather than offering teams a backdoor development tool.
What the meeting did not deliver was a breakthrough on the issue that matters most. The proposed 60/40 power unit split for 2027 remains unresolved, despite the FIA having previously spoken of an agreement in principle. The politics are tangled: Ferrari is prioritising its ADUO development, while Audi and Honda are wary of the additional investment any rule change would demand.
Any revision to the engine formula requires a supermajority - four of the six manufacturers - to pass, and with General Motors widely expected to align with Ferrari, the numbers do not currently add up to a deal. Several parties made clear in Canada that they want clarity on the engine question as soon as possible, but heading into the Monaco Grand Prix, no breakthrough had materialised.
The net result is a familiar one for F1's regulatory machine: progress at the margins, paralysis at the centre. Teams will welcome the extra test day and the pragmatic tweaks to race format, all of which make the transition to 2027 a little smoother. But until the manufacturers find common ground on the engines themselves, the most important piece of the 2027 puzzle will remain unfinished - and the clock is ticking.
