Williams introduces lighter chassis and minor aerodynamic updates at Azerbaijan Grand Prix.

Williams has brought a significant weight reduction package to the Azerbaijan Grand Prix, featuring new lighter chassis alongside small aerodynamic developments. The team spent much of 2026 struggling with an overweight car that compromised competitiveness.

The aerodynamic changes include removing a stay from the bargeboard footplate assembly and revising details around the rear wheel contact patch to improve underfloor sealing. Minor modifications were made to front and rear brake ducts and suspension cladding.

Williams has talked about implementing a revolutionary chassis construction method, though technical observers question whether revolution is needed when the team should focus on executing basics efficiently rather than reinventing established approaches.

The weight reduction represents the team's most important development, as excess weight has been a fundamental limitation throughout the season. Performance gains will depend primarily on the chassis changes rather than the modest aerodynamic updates.
