F1: Teams make power unit and aero updates galore in Baku

–by Mark Cipolloni–

17 out of 20 Formula 1 drivers have taken new power unit parts for this weekend’s Azerbaijan Grand Prix after the rule limiting how many components they may use was relaxed as part of the negotiations for the new Sprint Weekend format.

There are also a host of performance upgrades teams have brought – most aero in nature.
