FP1 at Interlagos under 2026 regulations remains one of the most open sessions of the year, with teams prioritizing data collection, new aerodynamic packages, and tire evaluations over outright pace. Recent championship form shows Mercedes drivers Kimi Antonelli and George Russell leading the standings ahead of Ferrari’s Lewis Hamilton and Charles Leclerc, while McLaren’s Lando Norris and Oscar Piastri plus Red Bull’s Max Verstappen sit close behind, yet practice timing sheets frequently feature midfield runners such as Pierre Gasly, Esteban Ocon, or Gabriel Bortoleto when programs align favorably. Variable track conditions, elevation changes, and the possibility of rain further scatter results, producing the tight clustering of implied probabilities across the full field.
