Three F1 Teams to Skip Final Day of Barcelona Pre-Season Test

Eight of the eleven Formula 1 teams are running on the fifth and final day of the 2026 pre-season shakedown in Barcelona, while Williams, Mercedes, and Racing Bulls are absent. Williams opted out of the test entirely, while Mercedes and Racing Bulls have already used their maximum allotted three days of track time.

Why it matters:

Pre-season testing days are a precious and limited commodity for teams to gather initial data on their new cars. A team's decision on how to allocate these days reveals early strategic priorities and resource management, offering the first hints of their preparation level and confidence heading into a crucial new regulatory era in 2026.

The details:

• Williams' Strategic Absence: The Grove-based team announced last week it would not participate in the Barcelona test at all. Team Principal James Vowles confirmed the team will be ready for the official first test in Bahrain in February and will complete a filming day beforehand to shake down its new car.
• Mercedes and Racing Bulls Maxed Out: Mercedes and Racing Bulls are not running on the final day because they have already utilized the maximum three days permitted at the Circuit de Barcelona-Catalunya. Both teams ran on Monday, skipped Tuesday, and completed further sessions on Wednesday and Thursday.
• Teams in Action: The eight teams continuing to run on the final day are Red Bull, Ferrari, McLaren, Audi, Cadillac, Aston Martin, Haas, and Alpine, gathering valuable last-minute mileage and data.

What's next:

The focus now shifts to the official pre-season test in Bahrain next month, which will provide the first true comparative picture of the 2026 grid. All eyes will be on Williams to see if its alternative preparation strategy pays off, while Mercedes and Racing Bulls will analyze their three days of Barcelona data to refine their packages before the next critical track session.
