Toto Wolff thanks FIA and reveals where Mercedes’ seven-tenths advantage in Australia comes from. Mercedes gains over half a second on rivals at the 2026 Australian GP.

The feeling was that Mercedes still had performance to extract ahead of qualifying for the Australian GP—and that proved true. The Silver Arrows made a significant leap from free practice to Q3, turning a gap of just a few tenths into more than half a second.

Rivals were particularly surprised by what unfolded on Melbourne Saturday. Lewis Hamilton loudly requested clarifications from the FIA, bringing the compression ratio issue back into the spotlight. According to the British Ferrari driver, starting seventh, the Federation must explain how the Brackley team can race with a car that could become illegal in the coming months.

Wolff “thanks” the FIA and reveals the secret behind Mercedes’ advantage

Meanwhile, Toto Wolff is enjoying his team’s outstanding performance. The Mercedes Team Principal openly praised the mechanics for their work, especially following Kimi Antonelli’s FP3 crash. “I’m really happy that those ground-effect cars are gone and that we’re finally back to doing what we do best. I feel relieved after the hard work we’ve put in over the past months. And the mechanics did a fantastic job today. Kimi’s car looked like it was made of Lego thrown on the ground, literally two hours before qualifying. Five minutes before the session, I told them we wouldn’t make it, then Max went off track, and that gave us just enough minutes to get the car out,” Wolff explained.

Wolff then revealed where the seven-tenths advantage over rival teams came from. “Everyone will say, ‘They were hiding their true pace,’ or ‘They still had something in the tank.’ But you really can’t hide pace—otherwise, you never know where the car really is. Sometimes we had 10 kg more in the car? Maybe. But we still don’t have enough confidence in understanding the cars to artificially run them heavier. We’re surprised by the gap, but I’ll gladly take it.”

Toto Wolff’s blend of relief and defiance marks a significant turning point for Mercedes as the 2026 era begins with a crushing display of dominance. While the “Lego car” miracle in the garage allowed Kimi Antonelli to secure a front-row start, the underlying technical gap of seven-tenths has sent shockwaves through the paddock, leaving rivals Ferrari questioning the very legality of the W17’s powerhouse performance.
