As the 2026 Formula 1 season opens in Melbourne, Aston Martin has arrived at the Australian Grand Prix facing a serious crisis with its new Honda power unit.
Two-time champion Fernando Alonso has admitted he feels disappointed with the situation as the team tries simply to complete the event.
The team entered the year with high hopes after signing designer Adrian Newey and forming a works engine partnership with Honda.
But severe vibration issues have caused repeated battery failures, leaving the team without spare batteries for the race weekend. Only two working batteries remain available for the weekend.
If one fails, one Aston Martin car would have to stop running. The team must now limit mileage to protect the remaining units while still meeting Formula 1’s qualifying rules.
A weekend already on the brink
The problems began before the cars even reached the track for the season-opening race at Albert Park. Aston Martin discovered heavy vibrations from the engine during preparations for the new 2026 power-unit rules.
Those vibrations damaged battery systems linked to the hybrid engine. The repeated failures quickly drained the team’s spare supply.
The situation has forced engineers to carefully manage every lap. Even qualifying runs must be planned with caution. If the car fails to reach the 107% rule in qualifying, the FIA could still allow it to start the race, but the risk remains.
On Friday, Fernando Alonso commented about the tension inside the garage due to the lack of running in Free Practice.
Speaking on Sky Sports and F1 TV, the 44-year-old said: “We are okay to do it. It’s more a question for Honda if they have a stock. Obviously, I feel disappointed to not have a stock, [with Honda] only supplying one team, but this is the situation.”
The team expected a fresh start with Honda under the new rules, not a shortage of critical parts at the first race.
A damaging Friday in Melbourne
The scale of the issue became clear during Friday’s practice. Alonso skipped the first session entirely because of power-unit concerns.
He completed only 18 laps in the second session and finished 4.933 seconds off the fastest time. Aston Martin appeared to be the slowest team on the grid.
His teammate, Lance Stroll, managed just 16 laps across both sessions. Both drivers spent much of the day in the garage while engineers checked the power unit.
Alonso later admitted that the limited running hurt the team’s understanding of the car.
“Not much learning, to be honest,” the Spaniard noted. “Unfortunately, the Honda issue in FP1 and some Honda issues as well in FP2 limited our number of laps today. That was not needed again because we need to recover a little bit in terms of understanding the car as well and the window of where this car operates.”
The situation also raised concerns about driver safety. Newey had revealed earlier that Alonso could complete no more than 25 laps in the car, while Stroll was limited to 15, because of the strong vibrations coming through the chassis. Engineers worry that longer runs could cause nerve damage in the drivers’ hands.
Newey: “I feel a bit powerless”
Team principal and chief technical officer Adrian Newey spoke openly about the problem during the FIA press conference in Melbourne.
“I think there’s a very clear action on Honda to try to reduce the vibration,” Newey said via Autosport. “They are working on that. It’s not going to be a quick fix because it involves fundamental balancing and damping projects that they will need to conduct.”
The vibration problem affects more than reliability. Because the engine lacks enough power, Honda must rely more on electric energy during parts of the lap.
That extra electrical energy use drains the battery earlier on straights. Drivers then lose speed at the point when they need power most.
Newey believes the Aston Martin chassis itself may not be as far behind as the lap times suggest. He estimated the car could be the fifth fastest on the grid, roughly three-quarters of a second to a full second off the leaders.
But he said the team lacks the data needed to improve the car.
“I kind of feel a bit powerless because we’ve clearly got a very significant PU problem,” Newey added. “Our information on the car itself is very limited because we’ve done so little running.”
To reduce strain on the batteries, Honda asked the team to run heavier fuel loads during practice. That choice prevented Aston Martin from completing the low-fuel runs engineers need to measure the car’s true pace.
Brundle warns Aston Martin of six months of pain
Former Formula 1 driver and Sky Sports analyst Martin Brundle believes the team could face a long recovery.
“Clearly, it doesn’t have reliability, doesn’t have speed,” Brundle said, according to GPFans. “It’ll take them six months to begin to really turn that around.”
Brundle also pointed to another disadvantage. Aston Martin is currently the only team using Honda engines, which means it lacks the shared testing data other manufacturers receive from multiple teams.
Despite the problems, Alonso has tried to keep a steady tone. He warned that outside criticism may exaggerate the situation.
“We are much less negative than media and people around,” he said. “We have a big challenge in front of us, but everyone in the team is embracing the challenge.”
The Spaniard’s relationship with Honda has been tense before, especially during the difficult McLaren-Honda years between 2015 and 2017. This time, however, he has expressed trust in the company’s ability to recover.
“I have 100 per cent faith that Honda will fix the problems because they did it already in the past,” Alonso said.
For now, Aston Martin faces the start of the 2026 season with serious uncertainty. The team must first solve its engine vibrations and battery failures before it can begin chasing the pace it hoped to show under Formula 1’s new rules.
