Aston Martin‘s 2026 season took off to a devastating start with the Honda power unit limiting the mileage in preseason and forcing retirement at the Australian GP. Amid the reported vibrations causing a plethora of issues to the AMR26, Honda has now come out and revealed the timeline to fix the issues in time for the Japanese GP.
Aston Martin and Honda’s partnership began this season, with the Silverstone-based team parting ways as Mercedes’ customer team. Honda arguably had the best engine in the later stages of the previous engine regulations, and we’re expected to deliver going into the 2026 regulations.
Unfortunately, the partnership began with the Honda engine not revving as high as the rivals, overheating issues, as well as vibrations from the Internal combustion engine, causing significant damage to the battery pack. Ahead of the Australian GP, Adrian Newey claimed that the vibrations from the Honda ICE risked causing permanent nerve damage to the drivers.
Ahead of the Australian GP, Honda brought a temporary fix to isolate the battery from the vibrations, but reliability continued to remain an issue with both Fernando Alonso and Lance Stroll retiring from the race at Albert Park. Amid the poor start to the partnership with Aston Martin, Honda Racing President Koji Watanabe came out and revealed the timeline to resolve the power unit issues, suggesting a fix will be available in time for the Japanese GP.
“I want to ensure that vibration mitigation measures are in place before Suzuka and that we can use the power unit without any issues . Of course, Sakura will do its part to achieve this, but I believe it will also be important to further deepen our collaboration with Silverstone. To that end, as managing director, I will work to strengthen the organization,” said Koji Watanabe (via AS-Japan)
Honda President highlights strengthening the F1 project following Aston Martin Team Principal’s “30 percent of their original team” comments
Adrian Newey, ahead of the Australian GP, detailed how the majority of Honda Racing’s senior management for the F1 project had either joined Red Bull PowerTrains following the team’s decision to exit F1 or had been redirected to other projects within Honda.
“When they reformed a lot of the original group had, it now transpires, disbanded, gone to work on solar panels or whatever. So a lot of the group that reformed are actually fresh to Formula 1, they didn’t bring the experience that they had had previously,” said Adrian Newey
“They re-entered with let’s say only, I’m guessing, 30 per cent of their original team and now in a budget cap era. So they started very much on the back foot and unfortunately they’ve struggled to to catch back up,” he added
Koji Watanabe came out and claimed that HRC has strengthened the staff. , as he said,
“I believe that, overall, we have strengthened the staff sufficiently. I think we now need to consider the areas and authority that need strengthening, as well as our collaboration with Aston Martin,” he added.
Former Aston Martin Team Principal Andy Cowell was one of the key members of Mercedes’ High Performance PowerTrains, and was crucial to the Turbo-hybrid V6 dominance of the Silver Arrows. Cowell has reportedly taken to the Honda factory in Japan amid the 2026 engine crisis.
