Vowles admits Williams' Barcelona flaws won't be fixed soon but maps out upgrade path

Williams team principal James Vowles has acknowledged that the car problems laid bare at the Barcelona-Catalunya Grand Prix will not be resolved quickly, while insisting the Grove outfit retains enough of the season to mount a recovery. The admission came via Vowles’ own ‘Vowles Verdict’ video series following a difficult weekend in Spain.

The team arrived at 2025 pre-season testing in Bahrain already at a disadvantage, having missed private running in Barcelona and carrying an overweight car. Upgrades introduced for the Miami Grand Prix did yield points in Miami, Montreal, and Monaco, but Barcelona stripped away that progress and exposed underlying weaknesses in the FW47’s characteristics.

“My expectation is that we won’t be as exposed as badly as Barcelona, but some of those issues won’t be rectified in the short term,” Vowles said. He described the Spanish result as “more of a blip relating to some of these characteristics of the track and elements that are not right in the car,” adding that the team has identified the specific problem areas and has a structured plan to address them.

That plan is spread across several rounds. Vowles pointed to upgrades arriving around Silverstone, potentially extending into Spa, with further developments targeting the period leading up to the summer shutdown. The most significant package — which he described as “really quite a new car” — is scheduled to arrive after the August break.

“That feels like a long way off, and it feels like it’s late in the season,” Vowles conceded. “The reality is we’re only one-third of the way through the season now. And even post-August break, when I’m talking about, you’ll still have nine races or so left to go out of 22 or 23.”

He framed the timeline as manageable rather than alarming, arguing that nine races represents a substantial window in which upgraded machinery can accumulate meaningful points. “We have time to remedy this and fix it, but we need to make sure we bring that performance in a timely fashion to the car,” he said.

Carlos Sainz, who joined Williams for 2025, has been central to the team’s scoring runs in recent weeks, and the pressure will be on the engineering group to deliver the promised upgrades on schedule if the team is to consolidate its position in the constructors’ standings before the season’s final third.
