Engines (power package) may be more of a factor in the early part of the season until they get them fully sorted.
Ferrari
Main team - 1, 2
Client team - 5, 6, 10, 11 (Alfa Romeo, Haas)
Mercedes
Main team - 3, 4
Client team - 12, 13, 14, 15, 16, 17 (Aston Martin, McLaren, Williams)
Redbull (ex Honda)
Main team - DNF, DNF
Client team - DNF, 8 (AlphaTauri)
Renault
Main team - 7, 9
So the non-factory Mercedes powered teams finished last, and all but one Redbull car died.
At least the Redbull cars were running strong, so they should be ok if they can sort the reliability issue.
The Merc powered cars though look to be in a world of hurt.
