When James Vowles took charge as the Williams F1 team principal in January 2023, the once-dominant outfit was struggling, having finished 10th in the Constructors’ Championship for the fourth time in five years. The former Mercedes strategist faced a monumental task — turning the team’s fortunes around, something he compared to steering an oil tanker, a process that was bound to take time.

Vowles immediately began implementing structural changes, moving away from outdated methods and bringing in key personnel. His biggest success came in mid-2024 when he convinced Carlos Sainz to join the team, selling him on his long-term vision. The decision proved fruitful, as the team secured fifth place in the 2025 World Championship, with Sainz exceeding expectations and claiming a couple of podium finishes along the way.

The 2026 season, however, has been much more challenging. The FW48 car arrived late, missing the first pre-season test in Barcelona, and was significantly overweight. Despite some gradual improvements as the season progressed — allowing Sainz and his teammate Alex Albon to occasionally score points in chaotic races — the car continued to suffer from fundamental performance issues.

To address these shortcomings, Williams has decided to undertake a complete redesign, similar to the approach taken by Aston Martin. A major upgrade package, substantial enough for Vowles to describe it as a “B-spec” version, is scheduled for introduction at the Azerbaijan Grand Prix in September. Provided the two planned Middle East races remain on the calendar, Sainz and Albon will have eight races left to improve results and lift the team from its current eighth position in the Constructors’ standings. Such a mid-season reset is an enormous challenge and serves as an acknowledgment that the original concept of the FW48 fell short of expectations.

Vowles views the situation as an opportunity for the team to prove its mettle. “In terms of our direction of travel, we have to, as a business, demonstrate that we can achieve the right engineering quality and build a competitive car during the season,” he explained. “It’s like trying to fly a plane while rebuilding it at the same time. But we need to prove to ourselves that we’ve evolved from where we were three years ago, and that we now have the capability to do this. At the moment, we’re on track to make it happen.”

He also drew parallels with Aston Martin’s current efforts under Adrian Newey, as that team too is working to develop a substantially revised car mid-season. “We didn’t have the right process systems or structural foundations in place,” Vowles said. “I know what efficient organizations look like, and even today, we’re still struggling to do many of the things that others can. It’s our responsibility to fix that — and we have to do it while continuing to move forward on track.”

The Williams story underlines how demanding Formula 1 can be, especially for midfield teams trying to compete with the sport’s leading quartet — Mercedes, Ferrari, Red Bull, and McLaren. Although Williams made notable progress over the past few years, transforming the team’s core operations takes time, and doing so while developing a new car to comply with the 2026 regulations has been a massive undertaking.

The 2026 season has seen the top four teams widen the gap once again, after several years of closer competition under the previous rules. Entering this campaign, those teams were fully prepared to focus their resources on building the most competitive cars possible, while Williams still had to invest heavily in improving internal processes. Vowles was aware the year would be challenging, but the extent of the difficulties exceeded his expectations. “I thought we’d manage to produce a car that was slightly overweight but broadly on schedule,” he admitted. “We never claimed to be the benchmark this year — it just needed to function properly. Unfortunately, we didn’t achieve that; we fell short of our own targets.”

Williams’s biggest issue during the winter was falling behind schedule. Designing and manufacturing a Formula 1 car involves coordinating thousands of new components, each needing to be designed, produced, and delivered on time to fit into the overall assembly. Attempting that while simultaneously refining the underlying processes was like playing three-dimensional chess — when one element slipped, the entire schedule unraveled.

“The first time the data flagged an issue, it was already too late in the process to make corrections,” Vowles explained. “And the strange part — which took me a while to fully understand — is that when you fall three weeks behind, as we did, it’s unrecoverable. There’s simply no way to make that time back because every subsequent step in the system is tied to those dates. Once one part falls behind, the entire sequence collapses. The effort needed to catch up is immense, and the only way through it is to compromise — which is exactly what you’re seeing now.”

Despite the setbacks, Vowles remains optimistic. He believes that the tough 2026 season will serve as a valuable learning experience for the team as it seeks to close the gap to the top contenders, including his former employer, Mercedes. “Understanding the throughput capacity of your operations facility is knowledge that Mercedes built up over at least ten years — probably from 2010 to 2026,” he said. “We’ve had to accumulate that same understanding in just one year, over this past winter. It’s not just about process systems; it’s about ways of working and the expertise that comes with it.”

Ultimately, Vowles prefers to see the glass as half full. “You should never waste a good crisis,” he reflected. “The number of changes we’ve implemented has set us up very well for the future, and I don’t think we would have made them if we’d achieved partial success this winter. As painful as it’s been, I believe it was a necessary step in our journey.”
