Aston Martin and Honda have reported "good progress" on finding solutions for the power unit vibrations that have plagued their 2026 season so far ahead of this weekend's Miami GP. Battery vibrations on the Honda-supplied engine have limited Aston Martin's race participation so far, with only one full race distance covered in the AMR26 thanks to
Fernando Alonso's P18 finish last time out at Suzuka.
The team in green find themselves dead-last in the Constructors', hardly a surprise given legendary designer-turned-team principal Adrian Newey warned of
'permanent nerve damage' for drivers Alonso and
Lance Stroll at the season-opener in Melbourne.
However, after a five-week break enforced due to the US-Iran conflict, Honda's Trackside General Manager and Chief Engineer Shintaro Orihara, and Aston Martin's Chief Trackside Officer
Mike Krack, appear more optimistic coming into this weekend's Miami race.
Aston Martin Honda report 'good progress' after dyno testing in Japan
Speaking to media, including GPblog, Krack examined the progress made during the break: "We had a couple of weeks due to the cancellation of the two Middle East events and we have used the time together with Honda to do some further improvement to our package.
Krack also explained that the AMR26 had been kept in Sakura, Japan, to work on the vibration issues.
"We left one car in Sakura after the race in Japan to continue working on the issues we have and I think we have come here with another package of countermeasures to improve our reliability, to improve the package simply. So I think collaboration went really well over the last weeks."
Orihara detailed further what sort of results the dyno testing have yielded coming into Miami, with "countermeasures" set to be implemented at the weekend that should help both the battery and the drivers in terms of comfort during the on-track action.
"So, as Mike mentioned, we brought the race car to the Sakura, then we did some testing, static testing, to measure the vibration of the actual car. And then we have applied some countermeasures on the car and checked the vibration situation on the car.
"And also we gathered a lot of data from the car because in the factory, we can put a lot of sensor and also we gather all knowledge of HRC engineers. And then we found some good progress on vibration.
"We’ve introduced the countermeasure into this event. So we found good progress on vibration of the engine's battery side, and also we can see some good progress on vibration for driver. So we are interested to see how that works at track here.''
