The 18-year old driver was one of just two rookies left in the field after 57 laps around Albert Park in treacherous conditions. But his efforts went beyond just seeing the chequered flag – he claimed the most places of any driver from where he started – a fact that tells the story of his weekend.

Kimi Antonelli may be the most hyped up of F1’s newest recruits, at least in part down to the comments Toto Wolff has made about his young protege ahead of his debut season. But his performance at the Australian Grand Prix lived up to that hype, despite his weekend being far from faultless overall.

His qualifying was made more difficult by a small error in turn 6 that resulted in damage to his car’s floor, leaving it to spark over the remainder of his final Q1 lap attempt. Gravel being run out on track was not an uncommon problem over the entire weekend, but was what caused Antonelli to run slightly wide there – ultimately compromising his ability to advance further into the session.

“I could feel the car bottoming on the straight and costing me a lot of performance,” he said. “Without the damage, I am sure it would have been a very different story for us.”

This underwhelming qualifying left Antonelli with a lot to do on Sunday in what would turn out to be incredibly difficult conditions on track. As the grand prix got underway, the rain mixed with the white painted lines and tight walls of the Albert Park Circuit proved to be race ending for some of his fellow rookies, but also for more experienced drivers in the field.

But Antonelli began his charge, saving himself from a similar moment as that suffered by Jack Doohan on the opening lap and from there displaying impressive car control. He made it around Nico Hulkenberg’s Sauber on lap 14 before losing the position again with a spin at turn four, similar to what was done by George Russell in practice. 

He recovered and reclaimed the place, plus one other on Lance Stroll, leaving him in P11 by lap 22 and in a position to put pressure on Fernando Alonso for several laps within his DRS range.

On lap 34, Alonso crashed after running onto on-track gravel in turn six leaving Antonelli to claim his position within the points as the safety car emerged to clear the incident. Throughout this period, and in fact the entire race, Antonelli demonstrated impressive knowledge of the Mercedes car and its systems by requesting changes before he was prompted by his race engineer, Peter ‘Bono’ Bonnington.

Just two laps following the restart, the rain began to intensify leaving every driver vulnerable as the entire field had switched to slicks under the safety car. After passing the Ferrari of Leclerc who had spun out in sector three, where the rain was most impactful, Bonnington guided Antonelli to box to switch from his hard tyre to the intermediate.

Mercedes opted to double stack their drivers at this stage, but this delay allowed Stroll to overtake Antonelli through the pitlane putting him back to P11. The rain continued however, and while others further up the order like Hamilton, Leclerc and Tsunoda gambled on sticking it out on slicks, the early call to pit Antonelli for intermediates allowed him to rise to P5 in the space of just two laps. This may have seemed a conservative, protective call for the rookie at the time, but it turned out to be pivotal in forming his final race result.

Kimi survived one final safety car restart and passed Alex Albon with a brave move on the outside of the fast turn nine with just one lap remaining, putting him into P4 by the chequered flag.

It’s a result that was initially threatened by a 5-second penalty Antonelli had earned for an unsafe release at his first stop. But following a successful right to review appeal by Mercedes, the penalty was overturned and his P4 result was reinstated.

“That was an incredibly eventful race!” Kimi concluded. “The conditions were super tricky out there. We had so many different conditions that we had to cope with today, but I think we did a good job as a team.”

“I was happy with how we managed everything from start to finish and to come home P4, having started P16, is really positive. I definitely can’t complain about how my debut race in F1 has gone. It was also great to see George up on the podium for the team. Whilst we didn’t have the pace to challenge the McLarens, it’s always good to pick up silverware.”

While this may not have been the case, Antonelli’s pace was not to be sniffed at – he ranked fifth for average pace out of the finishing drivers, just behind his teammate Russell but ahead of more experienced drivers like the Ferraris of Leclerc and Hamilton, plus the Williams of Albon and Racing Bull of Tsunoda.

“The whole weekend has been a good learning experience. Being knocked out in Q1 after suffering floor damage yesterday was obviously disappointing. To bounce back today though, and experience so much in one race, is really good for my development as an F1 driver.”

Antonelli’s own comments about the role this weekend played in his F1 journey point to the mature attitude he has to his debut season, something spoken to by Toto Wolff also. “Kimi showed a great deal of maturity, in addition to the speed we know he has, to fight through from P16 to P4.”

On signing Antonelli, Wolff said Mercedes were “convinced of his talent before” but a “question of maturity” remained, but they opted to take the risk with the knowledge that Kimi was their long-term future and so there was time to develop the off track skills and “maturity” needed to deal with the pressure F1 brings.

But what his on track performance, radio communication and attitude to the peaks and troughs of his debut weekend demonstrated is that this development may not take as long as Wolff or Mercedes were perhaps anticipating. When his apparent resilience was mixed with his inherent speed and race craft, it made for a driver who recovered from tricky moments quickly and pushed the limits to pass more experienced drivers on a difficult track.

The approach Mercedes took, and are taking, to his debut is one that seems to be different to that being taken by other teams on the grid fielding rookies this year, perhaps impacted by their knowledge that he is their long-term prospect. But this means Antonelli can feel secure in establishing and building his performance over a weekend, and his debut season, without the threat of his seat being pulled from under him.

It is of course easier to observe these dynamics on a weekend where the resulting performance is positive, but the tough conditions and small mistakes endured in Australia were perhaps enough to prove that these characteristics will endure through other challenges.

His test runs in Formula 1 machinery demonstrated similar skill, as have his past performances in the feeder formulae. In Silverstone’s 2024 F2 sprint race, he won by a margin of almost nine seconds despite torrential rain that ended the races of six drivers.

“We always knew the potential”, as Toto Wolff said post-race in Australia. Potential is one thing, acting on it on an F1 debut is another, and it makes Antonelli an exciting prospect to follow over the rest of the year.
