The Australian Grand Prix weekend is turning into a nightmare for Aston Martin. After just one free practice session, the team led by Adrian Newey already finds itself facing a major reliability crisis.

The launch of the 2026 Formula 1 season could not have started more difficultly for Aston Martin. During the first free practice session of the Australian Grand Prix, the British team was almost absent from the track.
The problem appeared at the start of the day when Fernando Alonso could not even take to the track. The Spaniard’s car remained stationary in the garage due to a technical issue related to the Honda power unit.
His teammate Lance Stroll did manage to leave the pits, but his running was extremely limited. The Canadian completed only three laps, all very slow, before he too had to interrupt his program and return prematurely to the pits.
Result: Aston Martin finds itself with a colossal mileage deficit from the first day of a crucial weekend to understand its new car. A situation already worrying, but which is in reality only the visible part of a much deeper problem.
A battery problem worrying Adrian Newey
The team’s director, Adrian Newey, quickly clarified the origin of these difficulties. Contrary to what some imagined, the cars’ stoppage is not directly linked to the Honda engine vibrations observed during winter testing.
According to the British engineer, the issue this time stems from a failure in communication between the battery and its electronic management system.
“We are short on batteries. We only have two batteries left, the ones currently in the cars. If we lose one, it will obviously be a big problem. So we have to be extremely careful in how we use them” he explained.
The team had however arrived in Melbourne with four batteries available. But two of them were rendered unusable due to packaging issues, leaving Aston Martin in a very fragile position for the rest of the weekend.
Newey does not hide his concern about this situation: “Given our rate of damage on the batteries, it’s a pretty scary situation. We obviously hope to get through the weekend, complete enough laps and field two cars at the start, but for the moment it’s very difficult to be categorical.”
A withdrawal in Melbourne is no longer ruled out
Faced with this critical shortage of components, an extreme scenario is even beginning to be considered within the team.
A team spokesperson acknowledges that Aston Martin’s participation in the rest of the weekend is not fully guaranteed.
“It’s a possibility. We will try to run in FP2 and resolve what we can” he confides.
If another battery were to fail, the team could find itself unable to field its two cars for the rest of the weekend. A particularly embarrassing prospect for a structure that harbors great ambitions for the future.

Honda must urgently resolve the vibration problem
Beyond the immediate concerns, Newey admits that the situation is even more complex. Even when the engine is working correctly, it suffers from a significant performance deficit.
According to him, absolute priority must now be given to reducing vibrations coming from the power unit developed by Honda.
“For now, this vibration problem is absorbing a huge amount of energy in all areas. It’s something we absolutely must get under control as quickly as possible” he explains.
The engineer believes that this project will require fundamental work on the engine’s balancing and damping, which makes a quick solution unlikely.
“Once this problem is resolved, they can really start focusing on performance.”
A 2026 season primarily dedicated to stabilizing the project
For Newey, the realistic goal for this season now seems clear: first find a reliable base before seeking performance gains.
“Realistically, this season is first about mastering this vibration problem so we can run reliably, and then seeing how much performance we can add, especially at the level of the internal combustion engine.”
At the same time, Honda will already have to prepare for the future: “In parallel, Honda must start working on the 2027 engine. It is obvious that a big step forward will be necessary in terms of internal combustion engine power.”
Toto Wolff looks back on the end of the partnership with Aston Martin
Present at the press conference, Toto Wolff was also asked about the former collaboration between Aston Martin and Mercedes F1, which previously supplied the team’s engines.
The Mercedes boss was keen to clarify that the end of the partnership was not a decision by his team.
“Aston Martin has been a customer and partner of Mercedes for many years, and we still provide engines and other components for our road cars” he recalls.
“It was not a Mercedes decision to stop working with them. I think it was a deliberate choice to become a factory team with Honda and Aramco.”
A strategic decision that, for now, seems to plunge the British team into one of the most delicate situations on the grid at the start of this 2026 F1 season.
