Alonso: Aston Martin Honda Failure Is 'Frustration Beyond Imagination'

Fernando Alonso called his latest Aston Martin setback “frustration beyond imagination” after a Honda power unit failure ended his Mexico City Grand Prix qualifying in Q1. A water pressure problem linked to the energy recovery system forced him to stop immediately, leaving him 18th and facing a likely grid penalty once Honda changes PU components.

Why it matters:

Aston Martin’s 2026 season has been defined by reliability pain and a car that only occasionally finds its window. Alonso’s Q1 exit removes the team’s most experienced driver from a points chance at a circuit where the AMR26 had looked more competitive.

The details:

• Alonso had shown power-loss signs in final practice. Stopping about 100 metres from the garage was the safest call because the problem was likely too big to fix in time.
• He received a reprimand for failing to refit the steering wheel before climbing out.
• He believed Q2 was realistic, estimating Aston Martin was in the P11-P13 range rather than Q3.
• Mexico’s layout helped mask the car’s weaknesses: only two real straights, low grip and limited full-throttle running make it less power-sensitive.
• Starting at the back is costly in Mexico’s heat and altitude, where following closely causes temperature problems.

What’s next:

Honda has confirmed component changes on Alonso’s power unit, so a penalty is certain. With cooling and altitude already punishing Aston Martin, Alonso was blunt about moving forward: there is “not much we can do.”
