Alonso points to Honda power unit for Zandvoort Sprint qualifying nightmare

Fernando Alonso’s Dutch Grand Prix weekend unraveled almost immediately when Aston Martin’s new Honda power unit turned a promising practice into a Sprint qualifying nightmare. The two-time champion was left dead last on the grid after wrestling with engine drivability issues, just one race after the team had finally shown genuine progress in Hungary.

Why it matters:

Aston Martin appeared to be turning a corner in Budapest, where Alonso escaped Q1 for the first time all season. The Honda upgrade was expected to build on that chassis progress, but its introduction has instead created fresh headaches. If the Japanese manufacturer cannot quickly stabilize the package, the team risks squandering its first real momentum.

The details:

• Alonso explained the new Honda PU suffered from severe drivability problems in qualifying, with the engine "pushing under braking" and overdelivering power, making the car difficult to stop through Zandvoort’s tight corners.
• The Spaniard also lost straight-line speed when his SLM (straight line mode) failed to open the rear wing, removing a crucial aerodynamic advantage on the banking and main straight.
• Alonso stressed the upgrade remains immature and needs calibration time that a sprint weekend simply does not provide. He noted free practice had felt encouraging before the issues surfaced.
• With only one practice session before Sprint qualifying, Aston Martin’s engineers had virtually no window to iron out the new power unit’s behavior or diagnose the rear-wing fault.

What's next:

Saturday’s Sprint will serve primarily as a data-gathering exercise for Aston Martin. The team must fix the engine controls and verify the SLM mapping before Sunday’s main event, or it risks wasting another race weekend despite the underlying promise of its latest package.
