Williams has had both cars disqualified from Singapore Grand Prix qualifying following a DRS infringement.
After taking 12th and 13th on the grid, the FW47 machines of Alex Albon and Carlos Sainz underwent rountine post-session checks by the FIA, where an irregularity was found with the DRS slot gaps.
The technical regulations, specifically Article 3.10.10g state that the maximum limit of the adjustable position of the DRS flap is 85mm on both sides, with Williams explaining that its own measurements prior to qualifying showed the wings to be within the allowed tolerance.
Ultimately, Williams did not contest the FIA's measurement procedure or the accuracy of the results, and acknowledged the wing was outside of the technical regulations.
As such, both cars were formally disqualified, with the stewards' verdict and reasoning in full below.

During post-qualifying scrutineering, the rear wing of the car was found to be non-compliant with the Technical Regulations.
The uppermost rear wing element adjustable positions were checked. The DRS in the state of deployment exceeded the maximum limit of 85 mm on both sides of the rear wing outer area.
At the hearing, the Competitor admitted that, although their own measurement prior to the qualifying had shown the component to be within tolerance, the measurement subsequently conducted by the appointed FIA Officials revealed a larger gap than permitted and therefore the rear wing did not conform with the required dimension.
The Competitor did not contest the measurement procedure, the methodology, or the accuracy of the measuring equipment used by FIA.
The Competitor fully accepted the results of the FIA measurement and acknowledged that the rear wing fitted to the car did not comply with the requirements of the Technical Regulations.
Accordingly, the standard penalty applicable to technical infringements is imposed.
