Mercedes captured the 2026 Formula 1 constructors' championship at the Sao Paulo Grand Prix, sealing a full sweep of both driver and team crowns following a dominant campaign under the sport's revised engine and aerodynamic regulations.

The Silver Arrows secured their first constructors' title since 2021 after George Russell finished fourth and newly minted world champion Kimi Antonelli took fifth at Interlagos. Antonelli had clinched the drivers' title at the preceding Mexico City Grand Prix, becoming F1's youngest-ever champion.
