A human error in FIA race control sparked widespread frustration among Formula 1 teams on Friday during Sprint Qualifying at the Singapore Grand Prix. A technical blunder at the Marina Bay Street Circuit left several cars without full power in the opening segment of the session (SQ1), compromising the timing sheets and triggering premature eliminations.
The incident stemmed from a red flag stoppage in SQ1 to clear front wing debris from Sergio Perez's car. When the session resumed, race control officials failed to reactivate Overtake Mode—the supplementary electrical boost typically available in qualifying sessions. Realising the oversight, an official briefly switched the system back on for 27 seconds before turning it off again, creating confusion out on track.
With several drivers having already logged flying laps using full power before the stoppage, those attempting to improve their times after the restart were left at a distinct disadvantage. Among the worst affected by the power deficit were Arvid Lindblad, Lance Stroll, and both Williams drivers, all of whom were knocked out in SQ1 after missing the top-16 cut-off.
In light of the mishap, Williams formally requested that race control allow all 22 cars to advance to SQ2 to restore sporting fairness. However, the stewards rejected the appeal, citing regulatory constraints. Rerunning SQ1 was also ruled out due to tyre set limitations.
Following a meeting led by Nikolas Tombazis, the FIA's single-seater director, Williams and Racing Bulls expressed deep dissatisfaction with the events, though both indicated they do not plan to formally protest the sprint qualifying results. Aston Martin revealed they are keeping all options open while awaiting potential rectifications from the governing body, demanding a fair grid for Saturday morning's Sprint race. Nevertheless, the SQ1 classification will remain unchanged.
Compounding the chaos, Formula 1 management suffered a parallel issue with its timing system, independent of the FIA, which failed to record several SQ1 lap times and left drivers in the dark regarding their progression. This marks the second consecutive race weekend plagued by significant technical disruptions, after the start of the Bahrain GP—held in Malaysia due to Middle East security concerns—faced delays caused by a software glitch in power unit control systems.
In an official statement accompanied by an apology, motorsport's governing body clarified the situation:
"During the first period of Sprint Qualifying, a human error occurred in Race Control, unrelated to the timing issue also encountered during SQ1. This caused Overtake Mode not to be available following the red flag period in SQ1. Once it became apparent that Overtake Mode was not active after the restart, it was enabled for a period of 27 seconds before being turned off again. The FIA acknowledges that this unfortunate human error had an impact on the performance of certain cars, depending on their run timing and track position on their lap. The second and third periods of Sprint Qualifying were unaffected."
