Kimi Antonelli, 20, was crowned Formula One world champion on Sunday after finishing third in the Mexico City Grand Prix, securing a title that makes him the youngest champion in the sport's history and the first Italian to win the championship since Alberto Ascari in 1953.

The Mercedes driver claimed the championship with six race victories from his second season on the grid, dominating teammate George Russell despite a competitive field reshuffled by new regulations. Antonelli's victory came after a remarkable season that began with immediate promise and featured a five-race winning streak in May and June, including maiden wins in China and on the legendary Monaco street circuit.

Antonelli's path to the title was not without challenges. He started the season struggling to match Russell, who won the Australian season opener, but responded with remarkable consistency and adaptability. A rare qualifying error in Baku and a second-place finish behind Max Verstappen in Malaysia kept the championship battle alive briefly, but a dominant drive from 19th on the grid at Monza effectively ended Russell's hopes with six races remaining.

The new power unit and aerodynamic regulations introduced for 2026 reshuffled the competitive order, and while Mercedes had the strongest package, Russell struggled to adapt to the new demands. Antonelli, however, responded quickly, demonstrating racecraft and speed that his experienced teammate could not match. His consistency was the deciding factor — Antonelli finished 84 points clear of Russell in the standings.

The significance of Antonelli's achievement was underscored by the company he kept on the podium at Mexico City. Joining him were Max Verstappen, who won the race, and Lewis Hamilton, who finished second — the two drivers who have defined Formula One for the last 15 years. Their presence on the rostrum symbolized the changing of the guard, a moment Antonelli's race engineer Peter 'Bono' Bonnington described as "just the first chapter."

Antonelli, recruited into the Mercedes junior programme at age 11 with Hamilton as his mentor, has been groomed for this moment. His journey from karting dominance through F2 and into F1 has been rapid, but his performance against Russell — having the same car and same team philosophy — proves he earned the championship on merit. The young Italian's adaptability, racecraft, and composure under pressure suggest he is already a complete driver, and his championship will be referenced as a benchmark for young driver development in the sport going forward.

With the title secured, all eyes now turn to next season. But Sunday's result stands as a testament to a remarkable rookie campaign and the arrival of a new era in Formula One.
