Max Verstappen and Pierre Gasly only just made it out of the Barcelona pitlane before it closed 30 minutes before the start of the race because the two Honda-powered teams were waiting for the fuel to rise to the legal minimum temperature.
The limit is 10C below ambient temperature as declared to the nearest round number by the FIA from the official timing screens two hours before the start. That coincides with the time when the fuel has to go into the cars.
