Honda brings "countermeasures" to Miami after horror start to F1 2026 with Aston Martin

Honda is confident that the hardware changes it has brought to Miami this weekend will improve Aston Martin's F1 campaign

Honda is confident it has improved the situation that has so far plagued Aston Martin’s start to the 2026 Formula 1 campaign ahead of this weekend’s Miami Grand Prix.

The Silverstone outfit is bottom of the championship after its first three races with Honda as its power unit supplier, with the partnership plagued by vast problems that stem from excessive vibrations in the engine.

This has led to extreme discomfort for Fernando Alonso and Lance Stroll inside the cockpit, often limiting their mileage as the issue caused the two-time F1 champion to retire in China.

But last time out in Japan, Alonso became the first Aston Martin driver to complete a race distance this year ahead of the series' five-week break due to the cancellations of the Saudi Arabia and Bahrain rounds.

To take advantage of the enforced break, Aston Martin kept the AMR26 in Japan to test Honda vibration fixes on dyno bench, which essentially allowed it to reproduce the action on track.

Honda’s trackside general manager Shintaro Orihara said in Miami: “We brought the exact race car to Sakura, then we did some testing, static testing, to measure the vibration of the actual car.

“Then we 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 sensors.

“We gathered all the knowledge of HRC engineers and then we found some good progress on the vibration. Then we introduced the countermeasure into this event.

“So, we found good progress on vibration on the engine's battery side and also we can see some good progress on vibration for the driver. So we are interested to see how that works at the track here.”

Orihara revealed that the changes were ‘hardware related’ and he is “confident” in what Honda has brought to Miami, but refused to enter specific details about the “countermeasures”.

Aston Martin’s chief trackside officer Mike Krack also wouldn’t go into details about the power unit, but was more forthcoming regarding the chassis as it also has various problems.

The weight of the AMR26 is one concern, with the 2026 car understood to be at least 10kg over the regulated minimum weight of 768kg, which many teams have not hit following the significant drop from 800kg.

“There will be changes on the car,” said Krack in Miami. “We have worked on several items. Mainly reliability, but then also car weight, driveability was one big aspect and then in terms of external changes, they will come race by race.”

All in all, he also shares Orihara’s view that these changes should improve Aston Martin’s situation going forward, as it has so far failed to score a point and is approximately two seconds off the pace in qualifying.

“The work that we did together collaboratively over the last weeks, it will lead to a step forward,” said Krack.

“I think we will have less and less restrictions going forward. If you look back where we were, Melbourne and Shanghai, we went through all the details already of how these races went and how these events went.

“We can clearly see progress on the reliability side, on the collaboration side. I expect another step here. We also spoke in Suzuka that as soon as your reliability issues are mitigated, the spotlight is on performance.

“We have to acknowledge that we have to do some steps there as well. I also said that we cannot expect miracles coming to Miami, and this is the case. We are improving step by step, both reliability and performance, but we must not forget that the same applies to our competitors.

“It's a development race as soon as the season is on, and it's very tough to catch up.”
