Carlos Sainz Voices Worry Over ‘Serious’ Problem Williams Needs to Solve
Highlights
- Carlos Sainz worries over Williams’ overweight FW48 car issue.
- Major upgrade package planned for Azerbaijan Grand Prix in September.
- Williams scored 11 points, last points at Monaco with Sainz eighth.
- Audi gaining, Gabriel Bortoleto finished eighth at Silverstone.
- Sainz notes upgrades failed to deliver expected lap time improvements.
- Williams focuses on aerodynamic flow understanding to recover lost ground.
Carlos Sainz warns Williams faces a serious, weight-related problem after a subdued start to 2026. The overweight FW48 limits performance and undermines confidence heading into the summer phase.
Despite weight-saving efforts and a major upgrade aimed at Azerbaijan in September, returns remain limited. The new British GP front wing failed to move either car into points.
Sainz also received a rare one-lap penalty after a Safety Car mix-up, while Alex Albon retired. Williams stays on 11 points since Monaco, where Sainz finished eighth.
Rival Audi gains ground. Gabriel Bortoleto’s eighth at Silverstone lifts Audi to six points, five behind Williams. Audi’s chassis shows promise, but its first in-house power unit lags.
Sainz says recent upgrades have not delivered the expected lap time. He suspects an aerodynamic understanding gap under current rules, a theme he has addressed in recent rule change discussions.
Upgrades have not translated into lap time, despite the FW48 shedding weight.
The Silverstone race reinforced that view. Early clean air flattered pace, but once settled, Alpine and Audi pulled clear, leaving Sainz frustrated about sliding backward through stints.
He contrasts Japan and Britain. At Suzuka, the overweight car was 1.6 seconds off; at Silverstone, lighter and updated, it trailed by around two seconds, signalling a deeper correlation issue.
Williams readies further updates to arrest the slide. The Azerbaijan package becomes a reference point for recovery, and the next rounds will test whether understanding finally converts to pace.
Williams holds 11 points; Audi trails by five after Silverstone.
The campaign has also carried costly setbacks, including a recent Sainz DNF, which compounds the struggle for momentum in the midfield fight.
September’s Baku upgrade looms as a season-defining step for Williams.
