Renault will bring an upgraded power unit to the Canadian Grand Prix however they remain undecided as to which drivers will be getting the upgrade, both within the factory team and their customer teams also.

Cyril Abiteboul told Motorsport.com that the new power unit was ready to be introduced however decisions were still yet to be made on who will be getting the upgrade for next weekend.
"We have a new spec engine. We have yet to confirm the introduction, because the mileage is not the same across all cars, so we will see where and when exactly we will introduce that new spec.
"I think we have six engines available, subject to the last event on procurement in the supply chain.
"That's the plan, but not sure it's actually the best to introduce it in all six cars, in particular Red Bull.
"We need to look into that. We always work in partnership with teams, trying to do the best for the overall season result."
Abiteboul commented further on what specifically the upgraded power unit improved, as well as the possibility that Renault were already looking at next years regulations already.
"It's a small gain in power, although we know we won't be the only one," he added.
"It's mainly in the ICE that we can expect more power. This has to be the focus, and it will be the focus for all of this year, and maybe next year."
