Lewis Hamilton didn’t hold back after qualifying seventh at the Australian Grand Prix, expressing bewilderment and frustration at Mercedes apparent dominance.
With George Russell storming to pole by 0.293s over team-mate Kimi Antonelli, and Red Bull’s Isack Hadjar nearly eight tenths behind, Hamilton suggested the Silver Arrows’ advantage could stretch beyond normal competitive bounds.
For the seven-time world champion, now draped in Ferrari red, the sheer supremacy of his old team doesn't just feel like a job well done – it feels like a regulatory failure that could render the entire championship a farce before the European leg even begins.
“I don't understand it exactly,” Hamilton told reporters after qualifying. “They didn't show that they could turn it up in testing and now they've got this extra power from somewhere and we need to understand what that is.
“I hope it's not this compression ratio thing, hopefully it's just pure power and we've got to do a better job.”
The Briton was obviously referring to the 2026 regulations that capped the engine’s compression ratio at 16:1. Early signs suggest Mercedes may be exploiting a loophole that allows the ratio to expand in hot conditions, while the FIA’s compliance tests are performed cold.
Disappointed With FIA Oversight
“If it is the compression ratio [creating this performance gap] then I'll be disappointed that the FIA have allowed that to be the case,” Hamilton added.
“It's not to the book, and I'll be pushing my team to do the same thing so we can get more power.”

While the FIA plans to enforce tighter controls on the compression ratio from June onwards, Hamilton believes that could come too late to prevent Mercedes from racking up an early-season advantage.
“If they have a few months of that, then the season's done – I mean, not done, but seven races, a few months, you lose a lot of points with a second behind in quali,” he said, highlighting the potential impact on championship battles.
Q2 Issues Compound Frustration
Beyond regulatory concerns, Hamilton was also disappointed with his own on-track performance. After a strong start in Q1, where he took third and was just three tenths behind Russell, the Briton struggled through Q2 and Q3.
“It's been a great weekend up until Q2 basically, and the car was feeling good, really happy with the car and everything,” he reflected.
“Then we got to Q2 and we basically lost power so we then ended up having to come back in.

“On the medium tyre we were looking solid, and then when we ended up going back out, [we] ended up behind more people, losing more temperature in tyres, and then we just got out of sync and we just didn't get great laps out there.”
Hamilton’s comments combine incredulity and a touch of anger at what he sees as both Mercedes’ cunning and regulatory oversight that may have inadvertently given the German team a significant advantage.
Sunday’s race in Melbourne promises to be as much about managing perceived technical loopholes as it is about on-track battles.
