Honda Confident Vibration Fix Ready for Aston Martin at Miami GP

Honda says it has tackled the engine vibration problem that forced Aston Martin to run a limited package in Japan, and will bring a revised power unit to the Miami Grand Prix. After a five‑week development window opened by the cancelled Bahrain and Saudi Arabian rounds, static testing shows a clear drop in harmful oscillations. The real test now is how the fixes behave under race conditions.

Why it matters:

• Driver safety – excessive vibration can cause fatigue and long‑term health issues for the driver.
• Reliability & performance – reduced vibration eases stress on the engine and battery, allowing the car to stay on the pace without unexpected failures.

The details:

• The vibration was severe enough in Japan to be flagged as a potential health risk for Fernando Alonso.
• Aston Martin left a spare chassis at Suzuka after the Japanese GP so Honda could run targeted bench tests.
• Engineers added extra sensors on the power unit and hybrid system, feeding a richer data set back to the factory.
• Static testing confirmed that new counter‑measures lowered vibration amplitude on both the combustion side and the battery pack.
• Trackside GM Shintaro Orihara said the team “saw good progress on vibration for the driver” after applying the fixes to the Miami‑spec car.

What's next:

• Miami will be the first race where the updated package is run under full race load; telemetry will be scrutinised for any remaining hot‑spots.
• If the data matches the bench results, the solution will be rolled out to the remaining Aston Martin chassis for the rest of the season, with further tweaks planned for the upcoming European swing.
