Team Principal Toto Wolff has dismissed recent allegations regarding Mercedes’ 2026 F1 engine. The Austrian labelled the controversy a “storm in a teacup”.
FIA’s new compression unit limit test
Earlier this week, the FIA stated that an E-vote would be held among the Formula 1 Power Unit Advisory Committee, focused on the assessment of the 2026 F1 power unit compression ratio. Taking effect from 1st August 2026, compliance with the compression ratio limit would not only need to be visible at ambient conditions but would also have to be demonstrated at an operating temperature of 130°C. This new compression ratio test could have serious implications for Mercedes regarding their 2026 engine.
When asked for his opinion on the FIA’s proposal, Wolff was blunt in his response. The Austrian remains confident Mercedes will pass the assessment, regardless of the vote’s outcome.
“Yeah, for me, the way it works, you know, either we stay with the regulations like we are or the e-vote goes ahead on Friday with the proposal that came from the FIA. Both are OK for us.”
Wolff on a potential mid-season regulation change
Wolff and Mercedes initially challenged any accusations regarding their 2026 F1 engine. However, he now thinks his rivals are aware it’s not worth making a case for change.
“You know, we said it all along that this looks like a storm in a teacup, the whole thing. And numbers were coming up that were, you know, if these numbers would have been through, absolutely understand why somebody would fight it. But eventually, you know, it’s not worth the fight.”
Wolff went on to share that a possible mid-season change in regulation would not have a significant impact on Mercedes.
“It doesn’t change anything for us, whether we stay like this or whether we change to the new regulations. And that’s been a process. But we also want to be good citizens in the sport because it doesn’t make a big difference.”
Wolff shares Mercedes’ shift in approach regarding its 2026 F1 engine
On the topic of the FIA’s proposal, Wolff was asked if he thought the FIA handled the situation fairly or if the organisation had succumbed to pressure from the other teams. The Austrian shared his personal views on the situation and added that Mercedes had “changed opinion philosophically”.
While Mercedes believed their engine was compliant under current regulations, the collective challenge from rival F1 teams prompted a shift in approach. However, Wolff still believes that regulations should remain fixed.
“We then changed opinion philosophically. You can disagree with it because I believe regs are there to be made and you keep the FIA close to you and that’s how it should be. But, you know, if you have four other PUs that are putting immense pressure on the FIA at a certain stage, what choice do we have than not to play? We were pretty comfortable in even having a protest going on Friday in Melbourne. But is this what we want?”
Wolff’s respond to new allegations regarding Mercedes’ 2026 engine
Amid the compression unit saga, a new accusation towards Mercedes’ 2026 engine has emerged. All eyes are now on the Brackley outfit’s fuel supplier, Petronas. The Malaysian company has yet to receive approval for its 2026 blend ahead of the season opener in Melbourne. This could result in the team using a non-homologated fuel for the Australian GP.
Wolff, faced with yet another serious “illegal” allegation regarding Mercedes’ 2026 engine, snapped back during the press conference in Bahrain. The Austrian expressed his frustration in his response regarding a question on Mercedes’ 2026 fuel.
He added that he would not be surprised to see another allegation emerge in the coming days and weeks.
“This is another of these stories. We were told compression ratio is something that we were illegal, which is total bullshit, utter bullshit. And now the next story comes up that our fuel is illegal. I don’t know, you know, where that comes from, and it starts spinning again.
“Maybe tomorrow we’re inventing something else I don’t know, I’ve been on the Epstein files, God knows what.
“So you make a protest now, no? Another nonsense. You know, this is a complicated topic and the process and all of this, but there’s just not, can’t even comment.”
