Antonelli becomes F1's youngest world champion at 20

Kimi Antonelli is Formula 1’s youngest world champion after finishing third at the Mexico Grand Prix, clinching the 2026 title with four rounds to spare. The Mercedes driver, aged 20 years and 68 days, takes the record from Sebastian Vettel, who was 23 when he won in 2010.

Why it matters:

Antonelli’s rise reshapes Mercedes’ post-Hamilton era and marks one of the most dominant sophomore seasons in recent memory. Nine wins, 16 podiums and seven poles turned pre-season promise into a title run few expected to be this one-sided.

The details:

• Youngest champions: Antonelli (20y68d), Vettel (23y134d), Lewis Hamilton (23y300d), Fernando Alonso (24y58d) and Max Verstappen (24y73d).
• Antonelli is only the third driver to win the title in his second F1 season, after Jacques Villeneuve and Hamilton.
• His season was built on a five-race win streak from China to Monaco and calm recovery drives when Mercedes’ edge shrank, including fifth from 16th in Baku and a win from 19th at Monza.
• George Russell won the opener in Melbourne, but Antonelli took control from Shanghai and absorbed pressure as Ferrari, McLaren and Red Bull closed in.

What’s next:

The remaining four rounds now serve as a victory lap, but Mercedes cannot relax. Rivals are closing, and Antonelli’s ability to sustain this level will define whether 2026 is a one-off or the start of a long reign.
