Lando has been going on for quite a lot of laps after setting that 30.4
The times he went in the pits, he just had a front wing adjustment, so no refuelling. Considering how heavy the car might have been when setting that fastest lap, it’s safe to assume the MCL39 will blow the Bahrain-spec MCL38 out of the water when we come back to this track for qualifying. (For reference, the best McLaren managed in qualifying here last season was a 29.6)
