Williams boss Vowles dismisses speculation about 2026 car's weight

Williams team principal James Vowles has dismissed media speculation about the weight of the team's 2026 car, stating that not even the team itself knows the exact figure until it is fully assembled and measured in Bahrain. This comes after the team cleared delayed FIA crash tests, with its new challenger absent from the recent Barcelona shakedown.

Why it matters:

For a team like Williams, which is in the midst of a multi-year rebuilding project, starting the season with a significant weight disadvantage could be a major setback. In modern Formula 1, where margins are incredibly tight, being overweight directly compromises lap time and forces teams into a costly and time-consuming weight-reduction program, diverting resources from performance upgrades.

The details:

• Vowles directly addressed the swirling rumors, telling media including RacingNews365 that “there's no knowledge of the weight until we get to Bahrain.”
• He explained the practical challenge: the true weight can only be known once the car is fully built without its sensor packs installed, a state that does not yet exist.
• On the Aggressive Target: Vowles admitted the team set a “very aggressive weight target” for the FW48. He stated that if the car is over that target, the team will launch an “aggressive program to get it off.”
• Clearing the Air on Crash Tests: The team principal confirmed that earlier issues with FIA crash tests, specifically concerning the front nose box, have now been resolved. The car is on track to appear at the official pre-season test in Bahrain.

What's next:

All eyes will be on the scales in Bahrain. Vowles has promised transparency, stating, “I’ll come out and explain to everyone at the point where we know that.” His final hint—that the potential overage is not “miles over”—suggests that while weight may be a concern, it is unlikely to be a season-crippling issue. The true performance of Williams's 2026 package will begin to reveal itself on track in Sakhir.
