"Atlassian Williams F1 Team has taken the decision not to participate in next week’s shakedown test in Barcelona following delays in the FW48 programme as we continue to push for maximum car performance.

The team will instead conduct a series of tests including a VTT programme next week with the 2026 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. "
