Aston Martin explains deliberate delay in F1 car upgrades: "Little bit more careful"

Mike Krack, chief trackside officer of Aston Martin, has admitted that the team won't be rushing its upgrade packages this season as it balances the development of the 2026 car with resource constraints due to the change in regulations. 

The AMR25 was considered to be one of the slower cars during pre-season testing in Bahrain. But despite this, Krack has admitted that they will be more restrained on their rollout of upgrades, citing "more constraints financially and also resource-wise" as the main reason behind this. 

"I think what we have this year, you know, considering there is a big rule change, you have more constraints financially and also resource-wise, and that is why I think you need to be a bit more careful," Krack explained to Motorsport.com and other media on the Friday of the race weekend.

"I think last year we upgraded the car much earlier and you have just more potential to upgrade your car. I think this year because of resource and because of money, you have to be a little bit more careful and that is what we have decided to do."

When asked if the team wants to ensure upgrades actually work before bringing them to the track, Krack confirmed: "Yeah, I mean that, but that is something that you... you always try to use all the tools you have to make them as predictable as possible, so that's not any different than before."

After three race weekends so far this season, the Silverstone-based team sits seventh in the constructors' standings with 10 points thanks to impressive performances so far from driver Lance Stroll. Two-time champion and team-mate to the Canadian Fernando Alonso has had a difficult start to the season with two DNFs and a finish outside the points in Japan.

Krack has admitted that while the car has improved over last year's troublesome AMR24, it still lacks competitiveness in a grid that is constantly improving.

"I think you know when you see the whole field is going faster, going substantially faster than previous years.

"Now some are going more faster or less faster, but everybody goes faster, so that answer is quickly given. I think we can see it also here now."

Bahrain will be a good litmus test for the team who are keen to get more of an understanding of where their machinery sits in the grid hierarchy. 

"I think there's the least change here in terms of weather and wind compared to last year, so I think we will get a good idea here how the cars are compared to last year.

"But all in all, our car is easier to drive. Our car is faster, but now we have to make it faster in terms of competitiveness."
