Williams F1 Still Struggles with Outdated Infrastructure

Williams F1 faces a critical race against time, rebuilding infrastructure and culture before Formula 1’s 2026 revolution arrives.

For Williams F1, catching up is proving to be more about fixing deep structural issues than dealing with temporary setbacks.

One of the most telling signs of Williams’ decline over the past decade was the way the team managed the complex process of building a Formula 1 car. Everything was tracked through a single Excel spreadsheet. Thousands of parts, one file. It was more artisanal than Formula 1-level precision.

That outdated spreadsheet was just the tip of the iceberg. Behind it lay years of structural and industrial decline that new team principal James Vowles and owners Dorilton Capital are now working hard to reverse. But turning things around takes time.

To help speed up the recovery, Williams has pushed for changes to the budget cap rules. They argued that allowing underdeveloped teams to invest more would avoid creating a locked-in gap with the front runners. Without that flexibility, the system could have frozen the midfield where it stood.

Despite these efforts, Williams remains behind in several key areas. With the major regulation changes coming in 2026, that is a worrying sign.

“We still have some fundamental characteristics in the car that are not where they need to be,” James Vowles admitted.

“I don’t think we currently have the perfect balance for the drivers, and we are still a bit limited by the tools we have available. Some of these issues can be fixed this year, but others will need a longer-term shift in how we work.”

Vowles said the team’s progress is roughly where he expected it to be, given the depth of the problems they are tackling.

“In truth, the real secret is getting people to communicate better and setting up basic infrastructure that allows us to work more efficiently,” he explained. “What gives me confidence is that we are moving in the right direction and should see extra gains by 2026.”

At the heart of the rebuild is the production department, historically one of Williams’ weakest links.

“It can be hard for fans to understand why these changes matter so much, but everything we are doing is about bringing in better infrastructure, technology, internal systems, and performance indicators,” Vowles said. “We now track things like how long it takes to build a front wing, how much it costs, how much is made in-house versus outsourced, how many design iterations we go through, and how many wind tunnel hours are needed to find performance gains.”

“These KPIs are what really push a team to championship levels. The results you see on the track are just a reflection of all this work behind the scenes. That’s why my focus is not purely on track results yet. In 2025 and even 2026, we will still be in a phase of steady improvement.”

Vowles emphasized that their entire strategy is built around data. “If you keep improving these underlying variables, you will naturally build a faster and faster car year after year until you overtake your rivals.”

The transformation is not just technical. It is also cultural. Vowles has reshaped the way people work together at Grove.

“The cultural change has been massive. You have to work with a very different group of people, and that can paralyze an organization if it’s not managed well,” he said. “The scale of the change would have been huge for any company anywhere in the world.”

“But here is how you find those extra milliseconds. You set clear KPIs. You ask yourself every week how many milliseconds you gained, whether in aerodynamics, vehicle dynamics, or simulation.”

“These KPIs are what drive progress. The difference between a midfield team and a title contender is the intensity of that target. Instead of aiming for 10 milliseconds a week, you aim for 15.”

“Once you have the right data, the right tools, and good communication, you can push harder and work smarter without burning people out.”
