Williams is preparing a major overhaul for the second half of the 2026 Formula 1 season. The Grove team will bring an almost new car to the Azerbaijan GP, a decisive bet to regain competitiveness and strengthen Carlos Sainz’s confidence in their project.

The team’s performance has dropped drastically compared to the same period last year. With only eleven points scored so far, Williams currently occupies the lower part of the pack, ahead only of Cadillac and Aston Martin, a very different scenario from the one experienced at the beginning of 2025.
James Vowles, team principal, admitted that internal problems and unsuccessful impact tests compromised the development of the FW48. To meet deadlines, Williams opted for materials that were simpler to manufacture but increased the car’s weight during the construction process.
Although some updates have already been introduced, including a new wing at Silverstone, the main innovations are reserved for after the August break. According to Vowles, small components will arrive at the Belgium and Hungary rounds, but the big leap is reserved for the following races.
“Slightly more important components will arrive in Zandvoort, including a weight reduction. And then, practically, we will have an almost completely new car for Baku. This is the period we are really waiting for,” the manager told Motorsport.com.

The overhaul includes a significant weight reduction and the homologation of a second chassis, measures considered essential to improve the car’s behavior. Additionally, a lighter model allows for more setup options and reduces tire wear, especially in fast corners, one of Williams’ weak points this season.
However, the British team’s concern goes beyond the scales. Carlos Sainz recently expressed his dissatisfaction with other car limitations, mainly in the aerodynamic aspect, while rumors point to the Spaniard’s interest in a future seat at Audi.
Therefore, the package planned for Baku has gained strategic importance within Williams. More than recovering positions on track, the team needs to demonstrate that it is capable of evolving its project consistently and dispel, at least partially, Sainz’s doubts about his future at the Grove team.
