What happened: Aston Martin arrived at the Marina Bay Street Circuit expecting the track layout to suit the AMR26 on paper. Instead, the weekend fell short of expectations as power unit problems limited the car's competitiveness over the race distance.

Why it matters: The performance dip interrupted the momentum Aston Martin sought to build after a second ADUO turbo upgrade debuted in Spain and a September engine leadership handover. Smoother power delivery remains central to extracting consistent results from the AMR26 package across the remaining rounds of the 2026 calendar.

What to watch: On-track running at the United States Grand Prix in Austin, where the partnership marks Honda's 500th Formula 1 race, will test whether calibration changes address the Marina Bay setback.
