Overview
- Williams has committed to a full 'B‑spec' chassis and related parts planned to debut around the Azerbaijan Grand Prix as part of a staged midseason development programme.
- Team boss James Vowles says the Baku package will be a near‑complete car update that includes targeted weight reduction and follow‑on upgrades at Zandvoort.
- Carlos Sainz publicly questioned the plan Tuesday, saying prior updates at Spa, Budapest and Silverstone failed to produce expected lap‑time gains and that the Baku changes may not be enough.
- Sainz urged a factory‑level diagnosis of aerodynamic and flow‑dynamic problems after noting an overweight car was closer to the front in Suzuka than lighter, upgraded cars were at Silverstone.
- Williams sits on 11 points with no result since Monaco, rivals such as Audi are closing the midfield, and the team now faces reputational and personnel risk if the costly B‑spec step does not reverse the slump.
