Kimi Antonelli ’s record-breaking Formula 1 world championship triumph was highlighted by many superb performances. But which one was his best?

📌 The Core Development

Antonelli duly wrapped up his maiden F1 crown in Mexico with four rounds to spare – becoming the youngest-ever world champion in the process.

Our writers have picked out the moments they believe turned the Italian from a contender into a world champion in waiting.

🔍 Background & Sector Context

It may sound odd to pick one of Antonelli's few defeats against Russell, but his runner-up spot to the Briton at the season opener in Melbourne showed me the first tranche of evidence that the Antonelli who had rocked up Australia wasn't the same insecure rookie who had struggled through spells of 2025.

The Albert Park weekend was actually one of Antonelli's more challenging weekends, suffering a heavy 25G crash in FP3 that looked set to derail his weekend. It may have done a year prior, but this time the young Italian stayed cool and collected. And as Mercedes was able to pull off a full rebuild just in time for qualifying, Antonelli was able to shake off the incident and take second on the grid behind Russell despite not being able to finetune the car's set-up.

📊 Industry & Real-World Impact

In the race Antonelli then suffered from a poor getaway with no battery power as he was swamped and dropped to sixth, but Mercedes' pace advantage was thus that he was able to make a controlled recovery to second.

🔮 Strategic Outlook & What Lies Ahead

"If something like that had happened to me last year, the rest of the weekend would probably have been very compromised," Antonelli reflected in Austin. "When you have one year of experience, one full year in Formula 1, you come back the next year and you just feel better. Things happen a bit more easily, let's say, also because you're not forcing them to happen as much.

"I kind of took a step back in that regard and just tried to focus on the important things and enjoy the process as much as possible. Definitely, mentally I've been in a much happier place this year compared to last season. And especially when you've been working with the same group of people for one year, going into year two is a big difference as well. You know how to move on together as a team, especially from difficult situations."
