Honda has officially turned the page on its early-season reliability struggles, signaling a major performance push for the rest of the 2026 Formula 1 season. The breakthrough came at the Miami Grand Prix, where the Honda-powered Aston Martin team finally delivered on its potential.

For the first time this year, both Fernando Alonso and Lance Stroll crossed the finish line in the same race—a milestone that had eluded the Silverstone-based squad through a brutal opening stretch. After just one classified finish across the first three Grands Prix, Miami marked a turning point.

The root of the problem? Severe vibrations originating from Honda's power unit, which had been hammering the AMR26 chassis and raising health concerns for the drivers' hands and arms. Multiple batteries were knocked out in the process, forcing Honda to take an aggressive, source-first approach rather than just treating symptoms.

Instead of shipping the car straight back to Aston Martin's factory after the Japanese Grand Prix, Honda kept one of the AMR26s at its Sakura facility for extensive dyno bench testing. The move paid off. When asked in Miami whether the vibrations were gone, Alonso's response was emphatic: "Gone. I would say gone."

Honda's trackside general manager and chief engineer, Shintaro Orihara, welcomed the progress. "After the Japanese Grand Prix, I mentioned that HRC and Aston Martin had worked very hard to bring countermeasures to Miami," he said. "We have confirmed that they are working well, and the drivers have given us positive feedback."

With both cars completing full race distance and the sprint without any major reliability issues, the focus is now shifting. "The vibrations originated from the engine but were reproduced in the chassis," Orihara explained. "Now we can concentrate on optimizing our settings for energy management and handling."

For fans and teams alike, this signals that Honda is ready to unlock the true performance of its 2026 power unit—and Aston Martin might finally be ready to compete where it matters most.
