GPBeat reports that the FIA has set a speed-dependent MGU-K power limit for three sections of the Singapore GP Sprint and race. At 300 km/h, the alternative curve permits no MGU-K DC output.

The FIA has set a speed-dependent cap on electrical power from the MGU-K, a component of the power unit, in three sections of the 2026 Singapore Grand Prix Sprint and race. The permitted maximum falls at higher speeds. The FIA Race Director issued the power-unit information to all teams and officials on 8 October, ahead of the 9–11 October Singapore weekend.

The FIA labels the alternative curve Alt 2. It applies across three stretches of a lap: turns 1–5 (400–900 metres), turns 7–9 (1,750–2,150 metres) and turns 10–13 (2,600–3,000 metres). The Alt 2 ceiling on the MGU-K’s direct-current (DC) output is 250 kW at 220 km/h, then falls to 205 kW at 240 km/h, 150 kW at 260 km/h and 95 kW at 280 km/h. Those are maximums, not amounts the cars are required to use; at 300 km/h, Alt 2 allows no MGU-K DC output in those sections.
