Williams seeks reported F1 cost-cap review

Motorsport.com reports Williams is pushing for an F1 cost-cap review, with James Vowles arguing current spending rules still favour top teams.

Williams is reported to be pushing for a review of Formula 1’s cost-cap rules, with team principal James Vowles lobbying for changes to the financial regulations. Motorsport.com reported that Vowles wants the framework revisited and said rules around capital expenditure still protect an advantage for the leading teams.

The same outlet reported that Vowles has spent recent weeks trying to build support in the paddock for a broader overhaul. Motorsport.com also said the current structure combines a $215 million CapEx/OpEx limit, which Vowles believes has contributed to a two-tier field rather than helping rivals close the gap.

RaceFans separately reported that Carlos Sainz said Williams’ difficult 2026 season was not caused by Vowles’ recent criticism of the cost cap. No formal rule change was confirmed in the supplied reports, so any revision remains at the reported-discussion stage.
