What happened: Mercedes officially clinched the 2026 Formula 1 World Constructors' Championship at the São Paulo Grand Prix on Sunday. George Russell and Kimi Antonelli finished fourth and fifth at Interlagos to secure the points needed to lock up the team crown. Lando Norris won the race from pole position ahead of Max Verstappen.
Why it matters: The triumph marks Mercedes' first constructors' title in five years and their ninth overall in Formula 1 history. It also completes a 2026 title sweep for the team after Antonelli secured the drivers' championship the previous weekend in Mexico. Ferrari entered Sunday trailing by 126 points and could not generate the massive swing required to extend the fight.
By the numbers: Interlagos top five: P1 Norris, P2 Verstappen, P3 Hadjar, P4 Russell, P5 Antonelli. Mercedes entered Sunday holding a 126-point advantage over Ferrari in the constructors' standings.
What to watch: Formula 1 heads into the final rounds of the 2026 season with both world championships now settled.
