Toto Wolff left seething over potential rule change as Mercedes' rivals dug out

has labelled the agenda for the upcoming F1 Commission meeting 'a joke' as the team principals plan to discuss and vote on a proposal to make major changes to the 2026 engine regulations. Power units have been the talk of the paddock during the early stages of the 2025 campaign. First, there were calls for F1 to cut the upcoming regulations short and bring back V10 engines, running on sustainable fuels. This plan was largely supported by the drivers, but not by the OEMs, who voted the proposal down.

Now, a report from has revealed that the upcoming F1 Commission meeting will discuss a new proposal, which would involve making significant changes to the upcoming power unit regulations. "Reading the agenda of the F1 commission is almost as hilarious as reading some of the comments that I see on Twitter on American politics," Mercedes boss Wolff seethed ahead of the x.

"I really want to protect ourselves and make no comment - but it's a joke. A week ago, there's an engine meeting [on Friday in Bahrain], and [now] things like this end up on the agenda again."

Wolff's cynical view was not shared by some of his fellow team principals. In fact, Andrea Stella, whose McLaren team will be using Mercedes power units in 2026 as they do currently, emphasised his belief that debate and careful consideration are critical if F1 is to get its new regulations right.

"Well, my opinion is very clear, the principle I want to state very strongly is that it's the responsibility of all the stakeholders to make sure that the 2026 regulations are successful," the Italian explained when asked about the upcoming F1 Commission.

"Because there's no point in teams competing with each other if we don't have a good sport, and the quality of the sport, the quality of the spectacle, the quality of the racing is a function of the product from a chassis and power unit point of view.

"So I think keeping the conversation open, such that we really go into the details, considering overtaking, considering power deployment, considering power harvesting - everything that determines the quality of the product, therefore the spectacle, therefore the health of the business, we should look into that and we shouldn't say it's frozen.

"I think we need to have this open mind, keep working on that, obviously these adjustments don't have to be structural, we're not going to change the hardware, but if there's minor changes that we need to apply in the way we use the hardware, and this improves these characteristics which I said, then I think this is part of the responsibilities of all the stakeholders."
