Williams Formula 1 team missed the Barcelona shakedown for its 2026 car due to production delays but has passed all necessary crash tests and plans to test in Bahrain. Team principal James Vowles described the decision as incredibly painful yet necessary to avoid risks to spare parts and early-season preparations. He dismissed rumors of a significantly overweight chassis as mere media murmurings.
Williams Formula 1 team opted out of the behind-closed-doors Barcelona shakedown this week, the first testing opportunity for the 2026 pre-season, citing delays in its FW48 programme. The Grove-based squad lost three days of running at the Circuit de Catalunya, where other teams gathered initial data starting Monday. Speculation arose that Williams had failed crash tests and faced an overweight chassis, potentially 20-30kg over the 768kg limit, but team principal James Vowles refuted significant issues.
Speaking to select media on January 28, 2026, Vowles confirmed the team has passed all mandatory homologation and crash tests. "I'm pleased to say that we've passed all necessary tests and we're ready to run in Bahrain," he said. The team will conduct a promotional filming day, limited to 200km, before the official Bahrain tests begin on February 11. Vowles emphasized that attending Barcelona would have compromised spares, components, and updates for Bahrain and the season opener in Melbourne on March 6-8.
The FW48's development proved three times more complicated than previous cars, overwhelming the production system and causing parts to fall behind schedule. "We have absolutely pushed the boundaries of what we're doing in certain areas, and one of those is in certain corresponding tests that go with it. But those were only a blip in the grand scheme of things," Vowles explained. To mitigate the absence, Williams ran an advanced Virtual Track Testing (VTT) programme, simulating systems like brakes and cooling with the car, engine, and gearbox integrated.
On weight concerns, Vowles noted uncertainty until the second Bahrain test, when sensors are removed. "It's impossible to know it because you need the car together without sensors in the right form, and that doesn't exist today," he said. "The numbers we're talking about are probably small enough... It's not miles over." While most teams struggle with the 30kg lighter 2026 regulations despite heavier power units, Vowles remains confident, leveraging Mercedes' learnings from Barcelona. Williams, fifth in last season's standings, aims to transform aggressively under the new rules.
