Renault's teams will race a modified engine this weekend in Spain, which the French manufacturer hopes will deliver "improved reliability and driveability."
Earlier this year Renault came in for a barrage of criticism, especially from Red Bull Racing, who felt their engine was once again lacking in performance and reliability.
The lack of the latter means Daniel Ricciardo will arrive in Spain set to use his fourth of four engines allocated for the season.
There is, however, some good news as Renault's director of operations Remi Taffin has revealed both Red Bull and Toro Rosso will race updates units this weekend.
"The three week gap has given us an opportunity to look at all the information from the start of the season," he revealed.
"We have been flat out to counter the issues encountered early on and we will have a modified spec of engine for this race that should give improved reliability and driveability."
