Aston Martin drivers completed both the sprint and the main race at the Miami Grand Prix for the first time this season after fixes addressed vibration issues in the Honda power unit. The team had struggled with reliability problems earlier in the year but showed clear improvement in Florida. Fernando Alonso and Lance Stroll both finished the weekend without major incidents.
The switch to Honda engines created unexpected challenges for Aston Martin at the start of the 2026 season. Vibrations repeatedly damaged batteries and affected the drivers during the first three grands prix, resulting in just one official finish and multiple retirements. One car stayed in Japan after the Suzuka round so engineers could study the problems during the five-week break in April.
