The new 2026 technical regulations, featuring substantially higher electric power output and active aerodynamics without traditional DRS, have narrowed performance gaps across the field and introduced greater setup sensitivity. At the high-altitude Autódromo Hermanos Rodríguez, where thinner air reduces downforce and cooling efficiency, teams must balance grip and thermal management in ways that reward precise adaptation during FP2. Mercedes leads the championship with strong recent form from Kimi Antonelli and George Russell, yet Ferrari’s Charles Leclerc and Lewis Hamilton, McLaren’s Lando Norris and Oscar Piastri, and Red Bull’s Max Verstappen remain closely matched on single-lap pace. These dynamics produce a tightly bunched field where small differences in setup or track evolution can determine the fastest lap.
