What happened: Williams team principal James Vowles says an "almost entirely new car" will arrive by the Formula 1 Azerbaijan Grand Prix in late September. The Grove-based squad has struggled through the opening stretch of F1's new era after pouring much of last year's effort into 2026 preparation. Its FW48 was completed late and ran overweight, hampering the early campaign.

Why it matters: A mid-season overhaul of this scale is a major commitment for a team trying to climb the constructors' order after a slow start. Shedding weight and reworking the package could reshape Williams' trajectory for the back half of the season. It also signals where Vowles is placing the team's development resources as it fights for position.

What to watch: Watch whether the revised package appears on schedule at Baku in late September and how much of the FW48's weight deficit it recovers.
