What happened: Mercedes enters Sunday's São Paulo Grand Prix positioned to secure the 2026 Constructors' Championship after George Russell qualified second and Kimi Antonelli third. Both Ferrari entries face 10-place grid penalties for engine changes, leaving the Italian outfit starting deeper in the field at Interlagos.

Why it matters: Mercedes enters Brazil seeking its ninth Constructors' title with a 126-point cushion over Ferrari. A strong double-points finish from Russell and Antonelli would mathematically seal the team championship with rounds to spare.

What to watch: The São Paulo Grand Prix starts Sunday at the Autódromo José Carlos Pace. Mercedes will clinch the title if it maintains its points margin over Ferrari through the checkered flag.
