Overview
- On Saturday Lewis Hamilton produced a late Q3 lap to claim pole at the Mexico City Grand Prix by 0.009 seconds over George Russell, extending his career total to 105 poles and making him the oldest polesitter since 1982.
- FIA steward actions altered the grid after qualifying, with Max Verstappen given a one‑place grid penalty for a Friday practice collision and several outlets reporting that Liam Lawson was disqualified from the qualifying classification for an alleged MGU‑K power breach though accounts of that ruling vary.
- Kimi Antonelli was moved up to fourth on the grid and only needs to finish ninth or higher on Sunday to clinch the 2026 drivers' championship regardless of his rivals' results.
- The weekend has been hit by reliability and personnel disruptions, including Hamilton stopping with a power‑unit failure in Friday practice, Fernando Alonso being told to stop in Q1 because of a suspected water‑pressure issue, and Haas drafting in Ryo Hirakawa to replace Esteban Ocon for the weekend.
- Mexico City's high altitude and the long run to Turn 1 amplify slipstream and tyre‑management effects, increasing the tactical value of starting positions and shaping how teams will defend or attack in Sunday's race.
