Williams to Skip First 2026 Test, but Season Still Within Reach

Williams confirmed it will miss the opening pre‑season test for the 2026 season in Barcelona, citing chassis‑development delays. The decision follows a strong 2025 campaign where Carlos Sainz helped the team finish fifth in the constructors’ standings. Sainz’s earlier warning that the new Mercedes engine must be paired with a flawless chassis now feels prescient.

Why it matters:

The 2026 rule package introduces a new power‑unit formula, and Williams will run the same Mercedes engine as McLaren, Alpine and the factory team. With engine performance largely equalised, a competitive chassis is the only differentiator that can turn that power into points and re‑establish Williams in the midfield.

The details:

• Barcelona test: Five‑day window Jan 26‑30, teams limited to three days of running – Williams will sit out the first of three winter tests.
• Sainz’s warning: “We have a great engine, but we must get everything right with the chassis to stand out,” he said to El Partidazo de COPE.
• Leadership hiccups: Team principal James Vowles, former Mercedes strategist, has already dealt with setbacks—from withdrawing Logan Sargeant in Melbourne 2024 to floor‑measurement errors in 2025.
• Upcoming schedule: FW48 launch set for Feb 3, followed by a Bahrain test (Feb 11‑13) and a final Bahrain session (Feb 18‑20) before the season opener in Melbourne on Mar 8.
• Engine advantage: The Mercedes power unit is widely expected to be the benchmark under the new rules, giving Williams a solid base if the chassis can match it.

What's next:

Williams will focus on the February launch and the Bahrain tests to validate aerodynamics, cooling and DRS compliance. A smooth run there could keep the team in contention for points and signal that missing the first test is a setback, not a season‑defining blow.
