That stint was the longest he did so far and it was relatively consistent. We can go to the same source for some comparisons

Notably, everyone ran on the hard tires. If we pick the first 15 laps from that tally for Vettel, Hamilton and Verstappen and compare the averages, we get:

1:22.284, 1:22.199, and 1:22.818 respectively. That comparison would assume that Sebastian Vettel started with a full tank. With more or less empty tanks, the last laps of Hamilton and Verstappen give a 1:20.354, and a 1:21.322.

Now we do have some caveats here and should be careful to jump to conclusions:

• We obviously do not know whether Seb had some fuel in his tanks.
• We do not know about any engine modes.
• The track might have changed between the runs (but Seb and Lewis should be relatively comparable, except maybe for temperature).
