Mercedes has a simple theory for why Kimi Antonelli’s rookie season zigged and zagged the way it did: the kid tried too hard when he thought he already knew the way.
Andrew Shovlin, Mercedes’ head of trackside engineering, reckons Antonelli’s mid‑season dip owed plenty to “unrealistic expectations” at the European rounds — the very places he’d grown up racing. The result was a classic rookie trap: overreach, frustration, then a reset that ultimately unlocked the speed everyone suspected was there.
Antonelli arrived with the biggest spotlight imaginable as Lewis Hamilton’s successor and promptly looked at home. Fourth in a chaotic, weather-ruined Australian Grand Prix. Five points finishes in the first six Sundays. A splash of star power in Miami with top spot in Sprint Qualifying. Then, suddenly, the grind: back to Europe, back to familiar venues, and back into his own head.
“He thought he knew the circuits, the results were going to come, and they didn’t,” Shovlin explained in Abu Dhabi. “On tracks he doesn’t know, he doesn’t have that expectation going in, and those weekends flowed much more smoothly.”
The Canadian Grand Prix briefly interrupted the slide — a maiden F1 podium as Mercedes banked a 1–3 — but the points dried up again until Hungary. Antonelli spoke openly about “overdriving,” the telltale rookie urge to manufacture lap time. After the summer break, the picture sharpened: calmer execution, a few weekends with a clear edge on George Russell, and two more podiums in Brazil and Las Vegas as Mercedes’ form ticked up.
Shovlin says the team now has a much better read on how to work with him. Antonelli’s feel for the car has never been in doubt — “Kimi can tell Bono exactly what the car is doing, and Bono knows what to do with it” — but the fine print of F1 weekends took time. Tyres, preparation, and qualifying risk levels were the big lessons.
The tyres are a story in themselves. Antonelli spent 2024 pounding around in Mercedes’ Testing Previous Cars program, running “academy” rubber that behaves differently. “Those tyres have quite a weak front,” said Shovlin. “You never end up with the same balance you actually have on the race car.” It meant some of the habits he built up before his debut didn’t translate cleanly.
Qualifying, too, was streaky for reasons both human and procedural. Melbourne set the tone early when a slow release from the garage trapped him in traffic and bounced him out. Through the summer, he oscillated between under‑committing on cold tyres and overstepping on the big laps. Budapest? “He got a snap in Turns 1 and 2, put too much energy into the rears, and you can’t get rid of that temperature around the lap,” Shovlin said. Suzuka’s fresh tarmac was another case study: “You need a lot of temperature at Turn 1, it’s a confidence corner. It took him almost all weekend to trust the grip would come.”
Counterintuitively, Mercedes expected the opposite learning curve. “We always thought the long run would take longest,” Shovlin admitted. “Actually, Kimi was really good on the long run straight away. It was the single lap that took work. If you qualify out of position, you don’t get to show the race pace because you’re stuck.”
To help, Mercedes cut back off‑track commitments, dialled up the simulator hours and simplified his working week. And once the results returned, they didn’t drift. “The nice thing with Kimi is, when he learns things, they become embedded,” said Shovlin. “He’s not making the same mistakes time and time again.” Crucially, he kept making Q3 and finishing races, which maximised the learning pile.
There’s also the dynamic you can’t coach: speed versus judgement under pressure. Across the final flyaways, Antonelli found a better balance. On a few Sundays, he had the legs on Russell — not an easy teammate to put away — and the podiums in São Paulo and Las Vegas confirmed the ceiling is high.
Mercedes has already locked him in with a contract extension, and 2026’s upheaval looms like an invitation. New power units, new aero, new everything. That could punish the established muscle memory of the field — and favour those who adapt fastest.
“Because he’s a youngster, Kimi can sit in the sim and drive it all day,” Shovlin said with a grin. “That gaming generation can talk, think, manage energy, strategy, while driving. It frees up the brain for the rest of the job. He enjoys it, and he’ll do as many hours as required.”
Strip the season back and it reads like the right kind of rookie year: some bruises, plenty of data, and flashes of the good stuff when the noise dropped away. If Antonelli’s end‑of‑year composure sticks, the internal bar at Brackley gets higher — and the 2026 reset might just suit the kid who learns fast and forgets his mistakes.
