SINGAPORE, March 20, 2026 — For the second time in two weekends, the 2026 hybrid rules have changed the shape of a competitive session before the racing has truly begun. Friday’s sprint qualifying at Marina Bay was skewed when Overtake Mode was left unarmed at a restart, then armed late and held for 27 seconds. The FIA admitted the cause was human error in Race Control.
The latest failure came at the end of SQ1, after Sergio Pérez’s Cadillac clipped the wall and lost its front wing. That red flag automatically disabled Overtake Mode, which is the 2026 successor to DRS. When the green flag was shown at 20:46 local time, Race Control should have re-enabled the mode from a manual menu. It did not. Seven minutes later, an operator noticed the oversight and activated the mode, almost exactly one second before the chequered flag. Race director Rui Marques then judged the situation unfair and turned it off after 27 seconds. By then, the damage to the session’s competitive integrity had been done.
To understand why those 27 seconds mattered, it helps to look at the rules. Overtake Mode is a proximity tool in a race and a full extra-power setting in qualifying. It gives a driver a separate half-megajoule on top of the standard 8.5 MJ allowance, raising the usable electrical energy to 9 MJ. At Marina Bay, the normal electrical power ramp-down starts at 200 km/h. In Overtake Mode, that taper is delayed, so the car keeps more of the MGU-K’s roughly 350 kW for longer. If that half-megajoule is used with perfect efficiency, it is equivalent to about 1.43 seconds of 350 kW — before the straight-line boost is even counted.
The lottery came down to track position. Lewis Hamilton, Ollie Bearman, Fernando Alonso and Arvid Lindblad had already completed their laps when the late activation happened; they received nothing. Valtteri Bottas, George Russell and Charles Leclerc were arriving on straights and took a substantial bite of the extra power. Oscar Piastri gained part of it, while Lance Stroll is estimated to have had the mode active for only 10 or 15 metres.
Carlos Sainz was the highest-profile victim. Eliminated in SQ1 and last on the sprint grid, he said roughly half of the field had effectively run its lap with an engine half a second faster than the other half. His side, he noted, was on the wrong end. Arvid Lindblad also missed the cut to SQ2 by a tiny margin, but he had already made a mistake at Turn 13, meaning Overtake Mode is not a clean alibi for anyone who went out.
The FIA later described the sequence as human error, separate from a timing-system fault that delayed SQ2. It also acknowledged that the 27-second window changed the performance of cars depending on where they were. SQ2 and SQ3 were unaffected.
Teams were not prepared to let it pass quietly. Single-seater director Nicholas Tombazis was seen working the paddock, and team representatives went to Race Control. Aston Martin pressed the point in the gap before SQ2 while Formula One Management worked on the timing glitch. A protest was available, but wiping the session would have reverted everything to practice order — and the cars at the bottom were broadly where they had been expected to be. The sport dodged a bullet in the same way it did at Sepang a week earlier. This error hit the opening segment of a sprint weekend, not a title-deciding Q3, and it did not eliminate a Mercedes, Red Bull, Ferrari or McLaren.
The failures in Malaysia and Singapore are different versions of the same problem. At Sepang, a wet-weather software map reduced the sector cap from 350 kW to 250 kW, took more power than intended at low rpm and then failed to give it back. Cars were effectively trapped in an offset mode during the formation lap. In Singapore, nobody was stranded, but somebody simply failed to press the button that arms a mode a driver cannot arm himself — then pressed it late, then unpressed it.
Max Verstappen had already asked after Sepang why the cars cannot just have a brake pedal and an accelerator. The 2026 rule set has instead produced power limits, megajoule accounts, offsets, Overtake modes, boost maps, turbo settings and start procedures, all imposed so the electrical half of a heavily constrained hybrid can be made to work. A forgotten prompt in Race Control can hand one car half a second and leave another empty-handed.
That is not technical development. It is the operating cost of an engine formula so heavily parameterised that part of the competitive order now sits outside the cockpit. The obvious fix is to make re-enabling Overtake Mode a checklist procedure with a second confirmation, or to automate it with a manual override only in clearly hazardous conditions. For now, Friday showed that a single missed menu in Race Control is enough to distort a weekend.
