Williams sits ninth in the constructors' championship with 11 points at the summer break, and its team principal has now put a name to the reason: the money it should be spending on the car is going into the building instead.
Speaking on The Vowles Verdict after the Hungarian Grand Prix, James Vowles said the cost cap has left Grove trapped between fixing its foundations and racing.
"We are in a strange position where we got very exposed this winter. We have many, many years where we haven't been able to build up our facilities to the level it needs to be. And what the cost cap does is it constrains you," Vowles said.
The trade-off is explicit, and he did not dress it up.
"So we are dedicating a lot of resources to making sure we are fixing those problems behind the scenes rather than bringing performance to the car in the current year," he continued. "Clearly, this winter showed that we have a long way to go. There's a lot more that we need to address and fix. And it's not the work of moments."
Talking to Formula 1's official website a few days earlier, Vowles was blunter about what the audit found. He arrived in 2023 to discover Williams tracking car production on spreadsheets rather than proper ERP software. Three years on, he says the deeper problem has not gone away.
"We're not driven by Excel sheets anymore, which is great, but we're still antiquated in terms of systems, processes, and ways of working," he told the site. "Sometimes you need these smacks in the face [...] to make sure that you're doing enough change quickly enough."
"The cost cap is the best thing that ever came in, I maintain that, but it also baked in some of these inefficiencies, and we're having to dig hard to get them back out while still producing a car that goes on track and updating it," Vowles said. "The amount we fell back is a surprise to me."
The drivers are living with the consequence. Albon and Carlos Sainz finished 17th and 18th in Hungary, two laps down, and neither has scored since Monaco. Watching Aston Martin's Hungary package leapfrog them into second-slowest was the moment the gap became visible.
"The kind of upgrade the Aston had we can only dream of that," Albon said in Hungary. "Fair play to them, yeah, we're going to be fighting with them on some races because of the straight-line speed we've got, [but] it's eye-opening for us, we know what our Baku upgrade is, it's not that."
Vowles has already pre-emptively lowered expectations for that September package. "What I can say is the Baku upgrade will not be enough to put us in the points scoring positions regularly," he said. "Mainly for me it's about understanding what went wrong this winter, we have some pretty nasty characteristics in these cars, what can't happen is we go into next year still carrying the burden that was 2026."
Sainz, who chose Williams over Audi and delivered two podiums in his first season, has recalibrated rather than walked back.
"I think there's no secret that my expectations, or let's say my timeline for how long it would take me to win a race again and for Williams to be the place to do that, have been delayed by a year or two," the Spaniard said. "Having said that, I see what the team is investing in the future. I still see the vision of the team being pretty clear."
The verdicts from outside differ mainly on how much credit Vowles has left. Autoweek's Phillip Horton called it "a deeply disappointing opening salvo to the new regulatory cycle" and noted this is the second time in three years Williams has had a delayed car build, but argued the team principal "has built up credit during his leadership" and has time on his side.
Motorsport.com's Filip Cleeren was harder on the drop and kinder on the response, pointing out that Williams has at least identified the flaws and hired against them: Piers Thynne from McLaren, Dan Milner and Claire Simpson from Mercedes. His conclusion was that 2026 is likely beyond saving and every eye in the factory should already be on 2027.
That is roughly where Vowles ended up too, with one addition — the rebuild is happening mid-flight.
"Effectively, the equivalency of flying the plane and rebuilding it at the same time," he said. "I know what efficient organisations look like. And even today, we are struggling to do a lot of what the others can do at this point, and that is on us to fix."
