Fernando Alonso and Aston Martin showed a promising start to the 2026 Mexico City Grand Prix weekend by managing the circuit's challenging high altitude better than expected during Friday's practice sessions. The AMR26 demonstrated solid performance despite the well-known difficulties posed by the thin air, which affects engine power and cooling systems.
In the first practice session, Alonso posted the seventh fastest time, while in the second session he was twelfth, with a notably smaller gap to the leader Charles Leclerc compared to earlier races this season. Aston Martin's car ranked as the seventh fastest overall on the day, indicating a competitive pace in a demanding environment. However, Lance Stroll faced some technical issues that required further checks before Saturday's sessions.
The Mexico City circuit presents unique challenges due to its altitude, which impacts turbocharger speed, brake temperatures, and the effectiveness of aerodynamic downforce. Alonso reported no major concerns with these factors, highlighting the car's adaptability. Aston Martin's power unit partner Honda received praise for their work in reducing turbo lag, which is crucial in such conditions. Pedro de la Rosa, an Aston Martin advisor, emphasized the car's strength in low-speed corners, an advantage on this particular track.
The circuit’s characteristics, combined with lower downforce settings, tend to favour experienced drivers who can quickly adapt to the handling nuances. Alonso’s feedback reflected this, as he was able to extract good performance despite the demanding conditions. Engine and brake cooling remain critical areas for all teams, given the reduced air density at altitude, which can affect reliability and performance.
While Aston Martin’s Friday performance in Mexico City exceeded initial expectations, the team remains cautious as they prepare for the rest of the weekend. Technical checks on Stroll’s car and ongoing adjustments will be important to maintain the positive momentum. Alonso’s measured optimism reflects the balance between the encouraging pace shown and the inherent challenges of this venue.
This assessment of Aston Martin’s handling of Mexico City’s altitude highlights the technical and driving demands of the circuit, as well as the importance of power unit efficiency and cooling strategies. The team’s progress on Friday provides a clear indication of their approach to managing these factors in the current Formula 1® season.
