Mistakes of Past Still Haunts Williams as Vowles Can’t Guarantee All Will be Well

James Vowles goes in-depth to explain the problems of Williams F1 as he says 20 years of underinvestment cannot be solved in 12 months, as he says no team can assure smooth running.

The horrors of past continues haunting Williams till date. Even after the takeover from Dorilton Capital and hiring of Vowles as F1 team principal, it has been a tiresome project to put the British heritage team back on the map at the front of the field, challenging their old rivals.

Vowles has tried his best to bring in the changes, which he has succeeded in, but there are continuous roadblocks along the way. After some hope in F1 2025, they hit another at the onset of 2026 when the project was delayed due to trying to achieve targets that were impossible.

Williams were already delayed at onset of F1 2026

As a result they suffered. The car they brought in Miami was supposed to be the car in Melbourne. The weight problem only added to the chaos. They are still in the recovery process, with Baku pinned as the next step towards a better future in latter F1 2026 and beyond.

The one shining light that emerged from all this was retention of both Alexander Albon and Carlos Sainz in fresh deals before the Dutch GP – especially the latter inking a multi-year deal. But Vowles had questions to answer, even to the media, leave alone his drivers and F1 team.

Vowles simply laid it out that they cannot solve 20 years of underinvestment in 12 months. Not to add, the cost cap has a negative impact as well. Even with the cost cap in place, it doesn’t drown the effort put in by the big teams all these years to build the best base possible.

Vowles is blunt to state ‘not going to fix Williams in 12 months’

“So, we’re not going to fix Williams in 12 months,” asserted Vowles to media. “It’s not going to happen. It’s 20 years’ worth of underinvestment that, with a cost cap, that’s one of the best rules we’ve made, what I’m doing right now is paying a lot of cost cap dollars in fixing problems that other teams don’t have.

“So it’s no surprise to me, and it shouldn’t be a surprise to any of you, that the top four teams pull away from everyone else when you get a regulation change, because that stresses the system entirely. I think that you’re seeing the negative side of a cost cap as well, you bulk in what of what’s happened 20 years before that.

“We’re not going to dig out every single problem that’s happened in one year, it’s just not going to happen. We will, however, make sure that every decision we’re doing is the right one for our long-term success. If I made all the decisions that were right for next year just to save myself or save a driver, it would mean you get a small spike and then you go backwards again.

“Every decision we’re making are the right decisions for this team for the next five years, not for one year. And that may mean that we’re not getting the success rate we want to across ’27, but it will mean that across the next five years, we’re moving forward,” summed up Vowles. Having said, the Williams F1 chief cautioned that this doesn’t guarantee anything for the future still.

What went wrong in the winter of F1 2025/26

It is because no F1 team can guarantee that they will get everything correct and that nothing will go wrong in the winter period before a new F1 season starts. He also explained what happened to Williams in the winter of 2025 when the technology only came alive once most part of 2026 work was done.

This certainly set them back at the onset of F1 2026. “There’s no team on the grid that will ever give you an assurance you won’t screw it up, because the facts are, probably misunderstood in the outside world, you’re making a thousand decisions in the winter, and you don’t need many of them to be wrong before you start putting yourself into the wrong path,” explained Vowles.

“And that’ll be the difference between a few tenths, but a few tenths these days is the difference between winning a championship or not. So you don’t go to the level of, using your terminology, screw up. You go to the level of what are the big building blocks you’re putting in place, which is a combination of people, which is different to what we had before, a combination of strength in the team that was different to what we had before.

“And for us, it’s we had a lack last year at the beginning of 2025 of simulation technology, that actually only came online in November last year. The car’s already pretty much done by that point in time. So what we were doing was using educated guessing, and we got some of it wrong,” summed up Vowles. To further explain how they got it wrong with the educated guess, he noted about the ride height.

Delayed system resulted in mistakes, no one can guarantee that it will not happen again

Vowles admits that the development they undertook in the winter was with the wrong ride height like Aston Martin. But the latter has corrected it, while Williams is in the process of doing it. This is a type of error, he says, can happen with any team and has happened in the past, will happen in the future.

It is how you fight back after getting it wrong is the key step. “If you look at our rear ride height, we developed at the wrong rear ride height, as did Aston for that matter and corrected it,” continued Vowles. “But that doesn’t seem like a huge amount.

“But you’re aerodynamically developing in completely wrong space, and it’s not driven by anything more than simulation telling you that’s a good direction for whatever characteristic you’re after, and it goes wrong. That error can still be made across any winter because you’re in a theoretical space against an actual space.

“That’s why you have these lovely seasons where you turn up and a team has dropped backwards or a team has moved forwards. So, not for a second am I going to promise anyone, because there’s no championship team that would. What you’re more trying to do is show that there’s enough depth that didn’t exist previously in the ways of working, systems, tools, processes, and people that allow you to catch as many of those as possible,” summed up Vowles.
