The FIA updated on Thursday the power unit component use for each team and driver ahead of this weekend's Spanish Grand Prix.
Under Formula 1's current regulations, drivers incur grid penalties if they use more than four of certain power unit components during the course of the season.
Needless to say, after four rounds, McLaren has already maxed out its component use for 2017.
