Kimi Antonelli Reveals Why He Won't Take Number 1 for the 2027 F1 Season

MEXICO CITY — The question came in the post-race press conference at the Mexico City Grand Prix, and the answer was as simple as it was surprising: Kimi Antonelli will not take the number 1 for the 2027 Formula 1 season. He will keep the number 12.

In a sport where the world champion's number is treated almost as a ritual, this is a break from convention. Max Verstappen took the number 1 after each of his titles. Lando Norris, after winning the 2026 championship, chose it for 2026. Antonelli is doing neither — and he has three separate reasons for it.

It will be the first season since 2026 without a number 1 on the grid. Lewis Hamilton kept 44 in 2026; from 2026 to 2026 the number 1 appeared continuously. In 2027 that run ends — by the champion's own choice, not by any rule.

What the rules actually say: number 1 is optional

The least discussed fact in this whole debate is the rule that underpins the decision. Under the current sporting regulations, the world champion is not obliged to carry the number 1. It is an option. The champion may take it, or may keep his permanent number. Antonelli has chosen the second path. This is not a rebellion; it is a considered choice — and that is precisely why it carries weight.

It also matters that 12 is his permanent number, registered to his name. Taking the number 1 does not mean losing 12 forever; under the rules the permanent number remains his. But in any season where a champion chooses the number 1, that is the number on his car. Antonelli has declined that trade.

Reason one: Ayrton Senna and an emotional inheritance

The first reason Antonelli gave is emotional. The number 12 is not just a number to him. It is tied to the driver he considers his idol — Ayrton Senna. In 2026, Senna won his first world championship in a McLaren carrying the number 12. Antonelli knows the historical parallel. He is the first driver since Senna to win the world championship with the number 12. That fact is not hollow to him; it is part of his identity.

He explained that the number 12 dates back to Formula 4. When he entered junior formulae, he picked it for the first time, and it has stayed with him since. It is a link to the early days of his career — the period when nobody knew him and every race was a fight. To drop that number would mean leaving behind part of the journey that brought him here.

The Senna connection is not merely sentimental. It is also a historical coincidence that Antonelli keeps underlining. Not since 2026 had a car carrying the number 12 won the world championship. That coincidence gives his decision the shape of a story — and in sport, stories often matter more than statistics.

Reason two: Staying grounded

The second reason is about temperament. Antonelli said he wants to keep himself grounded and humble. In his words, every season is a fresh start, and the number 1 makes that start heavier. When your car carries a 1, you have to prove in every race that you deserve it. That pressure is not easy for any driver.

Antonelli stressed that even after winning the title he has to do the same work he did before. Changing the number does not change the competition. For him, humility is not a performance — it is his way of working. On several occasions this season that humility served him well, when he chose to reduce risk and collect points rather than chase a bigger lead.

That temperament is notable given his age. Becoming the youngest world champion at around 20 is no small thing — breaking Sebastian Vettel's record, set in 2026 at 23 years and 134 days. Antonelli took that record by roughly three years. Yet there was no arrogance in his delivery.

Reason three: A private superstition

The third reason is the most distinctive — and perhaps the most human. Antonelli said, laughing, that the number 1 has never been a good number for him. It is not a logical argument, and he does not present it as one. It is a private superstition, visible across his behaviour throughout the season.

In Mexico City he explained that all week he had stopped himself from thinking about the title. Whenever the thought came, he pushed it down. That is why, even when the championship was mathematically secured, he did not fully accept it for a few moments. Sports psychology would call this a coping mechanism for pressure — but Antonelli calls it plainly superstition.

The superstition is not limited to the number. It shows in his entire race-week pattern. He repeats the same routine, goes out on track in the same order, and avoids talking about the championship. Asked whether it actually helps, he did not give a straight answer — he simply laughed. That laugh is a signal that he knows it is not rational, but does not want to change it either.

Wolff's interpretation: one sentence that needs care

There is a nuance here worth noting. Antonelli said he kept hearing the same thing over and over again. He did not directly explain what that sentence meant. According to this report, Mercedes team principal Toto Wolff offered an interpretation: that Antonelli spent the whole week being told repeatedly not to think about the title and to focus only on the next race.

That interpretation matters because it links Antonelli's superstition to a collective discipline. But it should not be read as Wolff's direct statement — it is an interpretation attributed to him and carried forward by the report. There are three layers here: Antonelli's sentence, Wolff's interpretation, and the report's rendering of that interpretation. Meaning can shift at each layer.

Comparison with contemporaries: the Norris and Verstappen path

Antonelli's decision is as different from his contemporaries as it is revealing of diversity within his generation. Lando Norris did not hesitate to take the number 1 after winning the 2026 title. Max Verstappen did the same. For them, the number 1 was an honour to display.

Antonelli sees it differently. He treats the number as part of identity, not decoration. The distinction matters. It does not mean Norris or Verstappen chose wrongly; it simply means each driver handles success differently. Some change their identity; some keep it.

The future of number 12: a question still open

As for the number 12, it is his permanent number and remains his under the rules. It is registered to his name, and winning the world championship does not take it away. So when he says he will keep 12, it means he will not put 1 on next season's car.

But one question remains open: will that number actually appear on the 2027 entry list? The answer will come from the FIA's official entry list, not from a press conference. Antonelli's intention is clear, but formal confirmation is still pending. This report should not be read as confirming that 12 is locked in for the 2027 grid — it is only the driver's stated intent.

Celebration plans: the human side of a champion

After winning the title, Antonelli also spoke openly about his celebration plans, and this part brings him down from the summit. He said he will celebrate with friends after the Brazil race. In his words, he probably will not be in the best state going into Las Vegas.

That sentence changes the tone of the whole report. On one side, the youngest world champion; on the other, a 20-year-old who wants to enjoy a win and knows it may affect the next race. This is not calculated humility — it is honesty, and that honesty makes him the most credible figure in the entire piece.

Three races, three cities: the final stretch

Mexico City, São Paulo and Las Vegas — this triple header is significant for him. In Mexico he secured the title. In São Paulo he will celebrate. In Las Vegas he will have to get back on track. The sequence turns the end of his season into a narrative — victory, celebration, and then a return.

It will be interesting to see how he performs in Las Vegas after the celebrations. But this report should not be used to predict whether his performance will drop. It is simply the honest admission of a young athlete, something the sports world often hides.

One decision, three layers

Read as a whole, Antonelli's decision appears in three layers. The first is emotional — the Senna inheritance and the number 12 carried over from Formula 4. The second is psychological — the effort to stay grounded and to treat a new season as a fresh start. The third is superstition — a private belief that 1 has never been lucky for him.

These three layers should be kept separate, because the report itself does not rank them. Antonelli gave all three together and left it to the reader to decide which weighs most. Anyone who merges them into one reason will simplify his story — and probably lose its real complexity.

In the end

Antonelli's decision is a reminder of a basic truth about the sport: numbers are just numbers, but the person who wears them gives them meaning. For some, 1 is an honour; for others, a burden; for others still, just a digit. Antonelli did not change his digit — because for him it is part of the journey that brought him here.

Next year, when a car bearing the number 12 appears on the grid, it will belong to the youngest world champion in history — but it will not carry a 1. That small detail is no less significant than any grand statement.
