Both McLaren's and Daniel Ricciardo have taken upgraded engine parts for this weekend's Spanish Grand Prix.
According to the latest component usage revealed on Friday, the three cars have taken a new turbocharger and MGU-H in Barcelona, while Nico Hulkenberg remains on the same unit used in Baku.
Renault has struggled for reliability this season with four power unit-related retirements in the first four races alone.
And the upgrade is aimed at resolving some of the issues while also allowing the drivers to use higher modes for longer.

“I don’t know how much detail they’ve gone into, or what parts have changed," Ricciardo commented on Thursday.
“Some materials have changed to help reliability. So, for now, that’s the target.
“Obviously we’ll see if that is more reliable, then we can start again pushing the power curve and all those other things that everyone does in qualifying and all that.”
For now, all three drivers remain within the permitted allocations of engine components for the season, so no penalties are applicable.
