The star of the Aussie F1, Daniel Ricciardo, began his adventure at Renault was not the ideal with the first day of opening of Monaco.
But team boss Cyril Abiteboul revealed he was confident that Ricciardo and team-mate Nico Hulkenberg are ready to shoot a corner.
The Renault boss revealed that a connecting rod problem that reduced power for Hulkenberg's return to Bahrain in the second round was finally resolved.
It was a horrendous start for Renault with Ricciardo and Hulkenberg who reported only a seventh place apiece.
We saw Renault, who was trying to be the best of the others behind the big three of the sport, languishing again in eighth place in the constructors' championship, very far from Red Bull in third position.
Ricciardo and Hulkenberg are 12th and 13th in the drivers' championship respectively.
And Monaco didn't start well with Ricciardo finishing 11th and a disastrous 17th, while Hulkenberg went only slightly better at 7th and 16th place.
But Abiteboul said the team was forced to drive their cars to reduced power in China and Azerbaijan after Hulkenberg's withdrawal in Bahrain.
Abiteboul admitted that the team kept the problem of the rod at the bottom of the horror season of the season while the team was quick to solve the problem.
"This winter we have been given the opportunity to focus properly on power gain and competitiveness gains," said Abiteboul. "This meant that we have consciously decided to focus on performance, to the detriment of reliability.
"It means that a number of engines that should have been used on the test bench to ensure reliability were actually used to develop the performance, so what it meant was a great start in terms of engine power, but less than standard reliability.
"Two reasons, one that you know is the MGU-K, and one you don't know, which is that the failure of Nico in Bahrain was actually a failure of the connecting rod, so generally a part you don't want to break, because it's a part in the lower part of the engine and a fundamental part. "
The team then proceeded to upgrade the Ricciardo and Hulkenberg engines before the last round in Spain.
While Abiteboul said the team retained power in reserve for the Spanish Grand Prix, Renault hopes to unleash the beast in Monaco, where Ricciardo is the title holder.
"It was a problem that we did not identify ourselves during the winter, we did not have a back-up plan, but at the same time I can say that it was a blow to the organization that meant some containment measures after the race that was massively reducing the power that was delivered for subsequent races, "explained Abiteboul.
"I can tell you that it was also an incredible reaction from all those involved, and in five weeks we were able to identify the problem, understand the problem, invent a new design, create new parts, test the parts, sign the parts on completing cycles and building new engines in sufficient quantities for ourselves and McLaren in time for Spain. "
Ricciardo, after the less important first day for Renault in Monaco, admitted that the team was far from the pace in the second free practice session.
"I felt quite comfortable in the morning and I was happy to be able to speed up quite quickly," Ricciardo said at the end of the day.
"However, we didn't take the step we needed in the afternoon. We made some changes, but maybe they didn't help as we wanted. After the afternoon session, we still have a few tasks to do to really find that touch more.
"As always in Monaco, it's great to return to driving a Formula 1 car on these roads. It's always special."
