Alonso's 'frustration beyond imagination' after Mexico Q1 power unit failure

Fernando Alonso called his frustration "beyond imagination" after a power unit problem ended his Mexico City Grand Prix qualifying in Q1. Aston Martin suspected a water pressure issue linked to the ERS system, forcing the Spaniard to stop just short of the pit lane entrance.

Why it matters:

Alonso had shown genuine midfield pace at a track that suited the AMR26 better than expected. Losing a potential Q2 spot — and perhaps a points fight — hurts an Aston Martin team already enduring a difficult 2026 season. It also underlined how reliability can still decide weekends.

The details:

• Alonso was 12th in FP2, just 0.769s off Charles Leclerc's Ferrari, suggesting he was firmly in the midfield battle.
• He topped the early Q1 times before Aston Martin called him in. The team said the problem was likely bigger than the garage could fix.
• Alonso believed P12 or P13 was realistic, not Q3, but still a valuable result.
• Mexico's layout helped Aston Martin: only two major straights and low grip mean less power sensitivity. "You hardly can go full throttle," he said.
• Starting P18 makes progress difficult. He expects huge temperature problems in traffic: "There is no way you can follow cars closely."

What's next:

Alonso was blunt about the cost: "We lost a big opportunity. Frustration is beyond imagination. But this is the story of the year." Aston Martin must now salvage what it can in the race, while Alonso faces a long afternoon from the back.
