A disqualification was what greeted Alex Albon and Carlos Sainz after Saturday night at Marina Bay for a technical infringement on the rear wing’s DRS slot gap.
The FIA’s F1 Technical Delegate, Jo Bauer, noted: “The uppermost rear wing element adjustable positions were checked on car numbers 23 (Albon) and 55 (Sainz). Both cars exceeded the maximum limit of 85mm on both sides of the rear wing outer area.”
That runs headlong into Article 3.10.10 (g) of the Technical Regulations, which governs the Drag Reduction System: when DRS is deployed, the gap between the two rear-wing profiles must be between 9.4mm and 85mm along the span.
As per protocol, the stewards confirmed disqualification for both drivers. Their summary was blunt:
- The DRS gap exceeded 85mm on both sides when measured by FIA officials.
- Williams admitted their own pre-qualifying checks had shown the assembly within tolerance, but did not challenge the FIA’s procedure, methodology, or equipment.
- With the part non-compliant, the standard penalty for a technical infringement applies.
“Bitterly disappointing”: Williams’ response
Team Principal James Vowles cut to the chase: “During FIA scrutineering after Qualifying, the rear wings on both our cars failed DRS slot gap checks. As a result, Alex and Carlos have been disqualified from Qualifying for tomorrow’s Singapore Grand Prix. This is bitterly disappointing for the team, and we are urgently investigating how this happened. At no point were we seeking a performance advantage, and the rear wings had passed our own checks earlier in the day, but there is only one measurement that matters, and we fully accept the FIA ruling. We have a car capable of scoring points here this weekend and will do everything we can to fight from the back of the grid tomorrow, and will immediately review our processes to make sure this doesn’t happen again.”
Why is an extra millimetre or two such a fuss? With DRS open, a wider slot gap can reduce drag more than allowed, buying a little extra top speed. The rules cap that gap at 85mm so everyone’s “push-to-pass” stays within the same aerodynamic envelope.
What it means for Sunday
Both Williams will be relegated to the back, which scrambles undercut maths and punctures a few strategy decks. Can Williams still nick points? On a track where track position is king and the Safety Car is a frequent guest star, anything can happen.
