McLaren team principal Andreas Seidl is in no rush to use Renault's upgraded engine, as he tries to plot a course through the remainder of the season that features as few grid penalties as possible. Only Daniel Ricciardo used the new Renault engine in France last time out.
Nico Hulkenberg was not fitted with the new, more powerful engine as Renault sought to avoid grid penalties in their home race.
While Lando Norris can currently take a new engine without sanction, doing so too early could open up the possibility of penalties later in the year. Carlos Sainz will incur a penalty if he takes the new engine, having lost one to a fire in the Australian Grand Prix.
Ricciardo outperformed Hulkenberg with use of the new engine at Paul Ricard, only finishing behind his team-mate by dint of a pair of post-race time penalties.
With McLaren fourth in the championship, and Renault their main competition, McLaren will not rush into using the upgrade.
