Renault has confirmed that it intends to bring its upgraded power unit to next weekend's Monaco Grand Prix.
The manufacturer debuted its B-spec power unit during in-season testing at the Circuit de Barcelona-Catalunya, with drivers from both Renault and Red Bull noting a step forwards.
Renault originally planned to bring the upgrades to Canada but has now decided to introduce the update at the upcoming round in Monaco.
"The current power unit used since Australia has had several smaller upgrades and all the drivers were very happy with the standard in Spain," said Renault engine chief Remi Taffin.
"In parallel, we’ve been working on the new spec since the start of the season but needed to sign off all the parts for reliability and mileage before using on track.
"The tests were very positive and showed it to be more powerful and driveable.
"We had originally planned to use the new version in Canada when the current units are scheduled to be removed from the cycle, but if we can get the units together and completely validated by Monaco we will use the ones available at this race."
