Mercedes System 1 crew principal Toto Wolff has referred to as on rival energy unit producers to “simply get your s*** collectively” after they voiced complaints to the FIA on Mercedes’ interpretation of the laws.
The 2026 energy unit laws prescribe an engine compression ratio of 16:1, down from 18:1 final 12 months. That compression ratio has at all times been measured at ambient temperatures when the engine is not working, so it does not account for any materials growth below warmth when automobiles are working out on monitor.
A number of producers have been frightened about Mercedes and Pink Bull Powertrains arising with a trick to extend the compression ratio nearer to 18:1 when the automobile is definitely working whereas nonetheless complying with the static check.
“We’ve got to, as we do, belief the FIA with making the best selections right here,” mentioned Audi technical director James Key on the crew’s 2026 automobile launch.
“It is new regs. You have to have a degree taking part in area. If somebody got here up with a intelligent diffuser and also you mentioned it is not the best factor to do, nobody else can have it, however you’ll be able to have it for the remainder of the 12 months. It does not make sense. We might by no means settle for that.”
Nonetheless, Mercedes is adamant its automobiles are totally compliant with the laws as they’re written, and has been considerably bemused by how a few of its rivals, which can also be believed to incorporate Honda and Ferrari, have been rallying in opposition to what it appears like is a black and white case.

“I simply do not perceive that some groups focus extra on the others and hold arguing a case that may be very clear and clear,” Mercedes F1 chief Wolff informed choose media, together with Autosport, on the crew’s launch. “Communication with the FIA was very optimistic all alongside and it is not solely on compression ratio, however on different issues too.
“Particularly in that space, it’s totally clear what the laws say. It is very clear what the usual procedures are on any motors, even outdoors of System 1. So simply get your shit collectively.”
He added: “The facility unit is authorized. The facility unit corresponds to how the laws are written. The facility unit corresponds to how the checks are being completed.”
Whereas it seems there might be no rapid change on the horizon, talks are nonetheless understood to be ongoing on any other ways of measuring compression ratios, comparable to including checks below working circumstances.
Any proposed options must comply with the same old governance procedures, which features a assembly of the F1 Energy Unit Advisory Committee and subsequently a vote via the F1 Fee.
However Wolff shouldn’t be notably impressed by efforts to vary the procedures on one thing that’s thought-about trade normal.

“Simply doing secret conferences and sending secret letters and hold attempting to invent methods of testing that simply do not exist… I really feel like I can simply say no less than from us right here, we try to minimise distractions, trying extra at ourselves than at everyone else when it is fairly clear what the regs say and in addition fairly clear what the FIA has mentioned to us and has mentioned to them up to now,” Wolff added.
“However possibly we’re all totally different. Perhaps you need to discover excuses earlier than you even began for why issues should not good. If anyone needs to entertain themselves by distraction, then everyone’s free to do that.”
The FIA has been clear that it no less than needs the matter totally cleared up earlier than the beginning of the season in Australia subsequent month, so the subject does not linger into the brand new marketing campaign when it needs the main target to be on the on-track competitors.
“We’re very eager to keep away from such controversies and to be sure that when individuals go racing, they perceive the foundations in precisely the identical approach,” FIA single-seater director Nikolas Tombazis informed Autosport on the Autosport Enterprise Alternate in London.
“Inevitably, when there’s such a brand new set of laws sure issues do come up, and we take the view that it’s our accountability to resolve these issues earlier than the primary race.”
