What happened: Track activity continues under sunny southern conditions in Texas as the paddock transitions into the afternoon session. The MSC Cruises United States Grand Prix marks a late-October stop on the 2026 Formula 1 regular-season calendar.

Why it matters: Second practice gives teams a critical afternoon window at Circuit of the Americas to dial in car setups for the rest of the weekend. Warm track temperatures in Austin shape tire degradation and race-pace preparation.

What to watch: On-track running continues at Circuit of the Americas through qualifying and Sunday's Grand Prix.
