Williams FW48 completes first on-track run at Silverstone after production delays

Williams finally got its 2026 challenger, the FW48, on track at Silverstone for a promotional filming day after missing the Barcelona group shakedown due to production delays. Both Alex Albon and Carlos Sainz completed initial laps, providing crucial first feedback and data ahead of the official pre-season test in Bahrain.

Why it matters:

For a team rebuilding its foundations, getting the new car on track—even briefly—is a critical morale and operational milestone. After being the only team to miss the Barcelona running, this shakedown proves the car is built and functional, allowing the team to transition from simulation to real-world testing and address any last-minute issues before the intense Bahrain test schedule begins.

The details:

• The running took place at Silverstone under a temporary testing livery, serving as a promotional filming day and a functional shakedown.
• Team Principal James Vowles acknowledged the team had been under significant pressure due to an "unprecedented workload" that caused the Barcelona delay.
• Prior to the track run, the team relied on an intensive "Virtual Track Test," a hybrid simulator and mechanical rig system, to develop the car.
• Drivers Albon and Sainz reported a generally smooth day, noting typical British winter conditions, and confirmed the run helped identify minor issues to resolve before Bahrain.

What's next:

All focus now shifts to the official pre-season test in Bahrain, which begins next week. The data and driver feedback from Silverstone will be analyzed to finalize the run plans and car setup for the critical three-day test, the final rehearsal before the season opener in Melbourne.
