Alonso's Mexico City Qualifying Ruined by ERS Issue: 'Frustration Beyond Imagination'

Fernando Alonso's Mexico City Grand Prix qualifying ended early when a suspected ERS-related water-pressure issue forced him to stop in the stadium section, turning a promising weekend into another painful chapter for Aston Martin. He will start 18th.

Why it matters:

Aston Martin had a rare chance to fight near the front. Alonso was only 0.7s off the pace in FP2 and looked competitive in Q1, while Mexico's layout masked the team's Honda power deficit. Losing that opportunity hurts morale in a season already defined by struggle.

The details:

• Alonso protested the call to park; onboard footage showed him gesturing angrily.
• Aston Martin confirmed a suspected water-pressure problem linked to the ERS system.
• His F1 TV interview was eight words: "Engine." "It was." "Correct." "Not from the back."
• He wanted to return to the garage but accepted stopping was safer for everyone.
• "Frustration is beyond imagination," he said, "but this is the story of the year."
• Mexico's two main straights and low-grip corners made it less power-sensitive.

What's next:

Alonso starts 18th, with recovery difficult but not impossible. The bigger question is how quickly Aston Martin can fix the ERS issue and find form in a car still far from the front in 2026.
