The Miami-spec upgrade, intended for Race 1 but delayed by winter build issues and a missed Barcelona shakedown, finally debuted in Miami and began cutting weight. Williams expects a clearer turnaround in the final third of the season.

Miami produced Williams’ first double-points weekend of the year as Carlos Sainz finished ninth and Alex Albon tenth, lifting the team to eighth in the constructors’ standings and clear of Audi. Reports differ on the championship arithmetic: some outlets say Miami gave Williams its first points of the season, others say it added three points to an existing two, a shortfall traced to an overweight FW48 early in the year. Williams was sixth-fastest across the weekend.

Sainz said the package reached the competitive baseline Williams had targeted but remained well short of the team’s long-term goal, and he said Alpine was roughly 20 seconds clear. He warned a full recovery could take months, said there was no single silver bullet and noted more parts and small updates are due over the next rounds. Team principal James Vowles described Miami as a better weekend and said the team brought around 30 performance projects to the car, including a new floor, new bodywork, front-wing changes, modified rear suspension and exhaust-blowing work. He said further development is planned through the Canadian round and beyond and the team hopes to use the Miami breakthrough to build momentum into the latter part of the season while acknowledging rival development paths remain an unknown.
