Well Jenson's car lasted 1.1 laps then the engine stopped, session quite likely to be over. Though the engine stopped incredibly quickly and totally, no Verstappen style hearing the engine literally killing itself. SO maybe electrical, get into the pits and reset it but doesn't look great.
36c air and 54c track temps, which will likely increase, well the track temp, through this session but later in the evening air will come down but track temp will likely come down loads. Even so 54c is a mile away from the 65c that made Malaysia actually cause issues and this looks a bang on two stop race anyway. The biggest difference in Malaysia was that the tire life was pushing Merc(and almost everyone) towards a 3 stop while Ferrari could just get into two stop, if Malaysia was a nailed on 2 or 3 stop for everyone Ferrari wouldn't have gotten close.
