It is a strange thing to win a Grand Prix from pole, win three of the first four rounds of the season, lead the championship by 20 points, and then immediately tell the world's media what you are doing wrong. But that is precisely what Kimi Antonelli did in Miami.
The 19-year-old Mercedes driver has identified the one weakness he is not yet ready to forgive in his own performance: the race start. Specifically, the clutch drop. Antonelli lost two positions at the lights on Sunday in Miami, and six in the Saturday Sprint. He converted pole into victory anyway, on a strategy call that overhauled Lando Norris's McLaren, but he was unwilling to file the lights problem under "good enough."
"I still don't have that confidence, being consistent with that," Antonelli said. "I still have a bit of uncertainty, so it's a big point that needs to be improved."
The self-assessment was unusually direct.
"I think also with the team, but for sure mainly from me," Antonelli added, "because I'm still a little bit inconsistent, especially on clutch drop."
The Sprint was particularly painful. Antonelli's grip simply was not what the team had expected, by his own admission, but he refused to use that as a deflection.
"But still, no, it's not acceptable," he said. "I think especially in a weekend like this, that the gaps are a lot closer, it can really change the race."
The technical context is the new 2026 regulations. F1's reset to a 50/50 hybrid split has made the first 100 metres of every grand prix a different proposition than the late V6-hybrid era. Drivers are now managing clutch bite and energy deployment in the same opening seconds, and several teams have publicly conceded they are still finding the right window. Toto Wolff used the word "mediocre" to describe Mercedes' starts over the Miami weekend, and admitted rivals have cracked the new energy code at the lights faster than his team has.
That is the part of the equation Antonelli is willing to share with the team. The clutch-drop muscle memory is the part he is keeping for himself.
"It's not acceptable," Antonelli repeated. "It's a big point that needs to be improved."
The context that flatters him is that the Mercedes is fast enough at one corner of the equation — qualifying — to mask the other. In Miami the field bunched, the storm-shortened Sunday brought the tyre window down, and Antonelli still had enough margin to win on pace. In a closer race, on a track where overtaking is harder, two positions off the line is the difference between leading lap one and surrendering the championship momentum.
The schedule helps him. The next round is Canada, then Imola and Monaco — circuits where the start matters far less than at almost any other venue. If Antonelli brings his start performance into line with his qualifying form by the time the championship reaches its decisive European leg, his 20-point cushion turns from a comfort blanket into a strategic weapon.
For a rookie leading the world championship, the most telling thing about Antonelli's Miami debrief was not the win, the pole, or the third straight victory. It was that, asked what he wanted to fix, he picked the one thing the leaderboard does not yet show.
