Challenges presented by the revamped Formula 1 rules have forced Williams to skip first 2026 F1 pre-season test at Barcelona-Catalunya scheduled for next week.
The Grove-based outfit revealed it’s currently facing substantial delays in the development and production of its new FW48, including failures in the FIA’s mandatory crash tests and challenges meeting the revised minimum weight requirements under the radically overhauled 2026 technical regulations.
The private Barcelona shakedown will allow all 11 teams a maximum of three days each on track to iron out initial gremlins in their new machinery before the official Bahrain tests in February, leaving Williams drivers Alex Albon and Carlos Sainz with limited running time ahead of the March opener in Melbourne.
In an official statement, the team explained that it has opted out to prioritize “maximum car performance,” choosing instead to run a Virtual Test Track (VTT) programme and other in-house evaluations at its Grove factory.
“Williams F1 Team has taken the decision not to participate in next week’s shakedown test in Barcelona following delays in the Williams FW48 programme as we continue to push for maximum car performance,” read their statement.
“We will instead conduct a series of tests including a VTT [Virtual Test Track] programme next week with the Williams 2026 F1 car to prepare for the first official test in Bahrain and the first race of the season in Melbourne.
“We are looking forward to getting on track in the coming weeks and want to thank all our fans for your continued support – there is a lot to look forward to together in 2026.”
Williams’ strategic pivot underscores the severity of the setbacks, as sources indicate the team has been grappling with a chassis that exceeds the new 768kg minimum weight limit (excluding fuel) and persistent issues in passing stringent frontal, side, and rear impact assessments required by the FIA.

Team principal James Vowles, who has overseen a remarkable turnaround since taking the helm in 2023—guiding Williams from the rear of the grid to a fifth-place finish in the 2025 constructors’ standings—faces his sternest test yet, especially after publicly committing significant resources to the 2026 project at the expense of last year’s car.
Echoes of the team’s troubled past reverberate through this episode, most notably the 2019 pre-season debacle when the FW42 failed to materialize for the first two days of Barcelona testing due to similar build and design flaws.
Then-deputy team principal Claire Williams labeled it “embarrassing,” a humiliation that precipitated technical director Paddy Lowe’s exit and contributed to the family’s sale of the team to Dorilton Capital.
Fast forward to today, and while Vowles’ leadership has restored competitiveness—scoring podiums in 2025 and securing lucrative sponsorships like Atlassian—the Williams FW48’s woes risk undoing that momentum.
Analysts note that sacrificing 2025 development for 2026 was a calculated gamble, but crash test failures signal deeper integration issues between chassis and the new powertrain demands.
The Barcelona shakedown, structured as two four-hour sessions daily with a midday break, offered a low-pressure environment for teams to validate systems like the manual override mode—a DRS successor providing electrical power boosts when within one second of the car ahead.
Without this data, Williams will enter the second Bahrain test (February 11-13 and 18-20) at a disadvantage, where every lap counts toward setup optimization and reliability baselines before the season opener in Australia.
