Of course we know times mean little at this point. But if the teams finished in that order at the first race, it would not be hugely surprising would it.

In contrast to last year, McLaren have completed a healthy number of laps. But Mercedes have put everyone else in the shade on lap count.

Manor also got some decent laps in after a slow start, and clocked a faster time than Haas. However Haas suffered a front wing failure and had to run the rest of the day at reduced speed.
