The 41-year-old endured a difficult 2025 as he went through a whole season without standing on the podium for the first time in his Formula 1 career.
Hamilton is back on form this season and could become a serious threat to Kimi Antonelli in the title race at just 41 points adrift of the teenager after seven rounds. So what has caused this recent Hamilton resurgence, which has been over a year in the making?

The previous ground effect F1 cars from 2022 to 2025 may be seen as an outlier in Hamilton's career as he struggled to fully get to grips with a car that the drivers could not hustle and move around to be fast, instead a smoother driving style was needed.
In his final season at Mercedes in 2024, Hamilton was largely outperformed by team-mate George Russell, although he did take two wins at the British and Belgian Grands Prix, and it was a similar story at Ferrari in 2025 against Charles Leclerc where the deficit was often even bigger.
But, the more nimble and narrower 2026 cars are a return to previous technical regulations where a more aggressive driving approach is rewarded and it seems to be helping Hamilton.
Immediately, he was able to visibly hustle the car more during pre-season testing and was a match for Leclerc in terms of pace at the season-opening Australian Grand Prix.
"From the word go in the Barcelona Shakedown, he said, 'this thing actually talks to me, I can get a read on what it's going to do, I like the way it moves around' and he responds well to that," said Sky Sports F1's Anthony Davidson.
He claimed his first Ferrari podium at the second round in China before two off weekends in Japan and Miami which led to a few questions, perhaps even from Hamilton himself, about whether he still had "it" - "it" primarily being raw speed.
There was pressure going into May's Canadian Grand Prix, an event Hamilton has enjoyed huge success at, and he delivered with his best Ferrari result of second, overtaking Max Verstappen late on.
Another second place followed in Monaco, which was more impressive given he outperformed Leclerc in the Monegasque driver's home event, before his masterful drive on Sunday in Barcelona to cap off a genuine return to form which has been 18 months in the making at Maranello.
"They [the team] have been so kind. You come back to the garage after a difficult race and they just say like, 'Don't worry, next time', they're just so supportive through it all," said Hamilton.
"But for sure, results like this change everything and for sure reinstate, if there is a lack of confidence, reinstates it all. And I hope that this was a convincing gap and race, but I think it's been happening over the last few races.
"The changes that I've asked for and pushed for all last year have been made and I now have the right team around me, I now have the right car around me, and now I can start doing what I do best."
Input on 2026 car
Hamilton described 2025 as a "building year" and believes one reason for his struggles was arriving at a new outfit which has a completely different culture to his previous Mercedes and McLaren teams.
The British driver also had no say on last year's Ferrari whereas he's been able to point the Scuderia in a direction he wants with their 2026 machine.
"The team have really listened and really worked hard to add performance and be innovative," said Hamilton, who has spent less time on the simulator in the last two months.
"This year is all about innovation. We came out with the bit on the rear exhaust. We came out with, what else was it, the rear wing, the Macarena. This is what I was asking for last year.
"It was like, this team has to be the leaders in that, and they've shown that they can and they will."
Hamilton joined Ferrari just three months after Loic Serra joined the team as chassis technical director. Similarly to Hamilton, Serra did not have full control of the 2025 car's chassis but has led the development of the current SF-26.
The Frenchman was at Mercedes during Hamilton's championship-winning years and was performance director for the 2020 Silver Arrows, one of the most dominant cars in F1 history.
That technical prowess has translated into a 2026 Ferrari F1 car that is the benchmark in the corners and suits Hamilton's driving style too.
The Italian Bono
In a key change made ahead of his second season at Ferrari, Hamilton's engineering team is now led by Italian race engineer Carlo Santi, who replaced Riccardo Adami in the role.
Hamilton famously worked with Peter 'Bono' Bonnington throughout his time at Mercedes, with the pair forging the most successful driver-engineer combination in the sport's history. By contrast, the Hamilton-Adami dynamic appeared far less smooth, particularly in team radio discussions, last season.
This year, the communication between Hamilton and Santi has been much smoother and clear, with the seven-time world champion rarely frustrated on the team radio, even during difficult sessions.
The Hamilton-Santi combination was originally an interim appointment but Sky Sports News learned earlier this month there are no plans to make any changes to Hamilton's engineer, who he calls "the Italian Bono".
"We didn't know each other, we'd never spoken and I didn't really know anything about him. We met and I think got on straight away," said Hamilton.
"It's great to be able to connect with an engineer other than what I used to have. I had it for such a long time and then you kind of lose that feeling because Bono's now doing it with Kimi [Antonelli].
"He's very, very quiet. You could tell it's hard for him to express his emotions. He's just smiley and, I'm giving him these big hugs and pulling him in, saying 'thank you'. I like to think that this [win] has probably reignited the love that he has as being an engineer as he has done for me as a driver."
Happy Hamilton off the track
Hamilton revealed he carried an injury for much of 2025, after a big crash during pre-season testing, and "unplugged from the matrix" after the season to reset himself.
He said: "I spent lots of time with family, lots of time with friends, real people that know me, that have never doubted me, have stuck to and by me my whole life.
"I just went on the mission from Christmas Day. The training that I put in was harder than I've ever experienced, to keep myself in good shape, because at the beginning of last year I got injured and carried that for months.
"I know to never second-guess yourself, never doubt yourself. You've got to continue to believe in yourself at the core. And those are the things that I've managed to reimplement into my mentality. I've rebuilt my mind to this point, to get myself back to where I was."
Hamilton has also admitted "I'm happier in my life as well", which partly must be down to his relationship with Kim Kardashian.
Mercedes team principal Toto Wolff was Hamilton's boss for over a decade and thinks it is having a positive impact.
"I saw him on the podium, on the telly, that face shows me that he's very happy. Maybe the girlfriend helps!" he said.
"[It] helped me to have a partner that you have a stable family life, and they seem to be getting on really well.
"I think it's all of those factors that put together the emotional and the personal and professional perspective. If they are in a good place, you win."
