Ricciardo: Renault planning new F1 development philosophy for 2019

Renault accomplished its goal of finishing top of F1's midfield last year, but questions were raised over the rate of its in-season development compared to nearest rivals Haas and Racing Point.

Nico Hulkenberg conceded towards the end of 2018 that Renault had "lost out" over the course of the season, having started with what was convincingly the fourth-best car.

Ricciardo, who has arrived from Red Bull to partner Hulkenberg in 2019, said he "expects good things" from the French outfit in this year's development race.

"I think the philosophy this year will be quite different as far as the upgrades we get," he claimed.

"I think the plan and the structuring is going to change, and their philosophy on what to bring and when to bring it. I believe that is going to change [as well].

"I will be part of that and trust that process, and hope we are staying ahead of the curve."

F1's midfield teams appear closely-matched again on the evidence of pre-season testing at Barcelona, so in-season development will likely be key to how that battle pans out.

Renault is known to have bolstered its factory in Enstone in preparation for 2019 to avoid further development struggles.

Its technical director Nick Chester said the scope afforded by the new regulations also gave the team more confidence about making progress with the RS19.

"It's partly because of the regulations we've got this year, the 2019 regs, that open up quite a lot of avenues," Chester explained.

"So there is a lot to be developed this year, in terms front wings, brake drums, bargeboards, sidepods vanes - there's a whole big area available for development.

"We put a lot of effort into our tunnel and aero programmes, so we'll be trying to get things through as quick as we can and put those gains on the car."

Ricciardo believes Renault's in-season progress will also come from continuous work on its engine, although the French manufacturer claimed it has already made a "substantial" step over the off-season.

"The exciting thing for Renault is that the last few years it is no secret that we have always been playing catch-up with the power unit, so the positive with that is we always feel there is more to gain than the others," said Ricciardo.

"So from that I will obviously always stay optimistic and feel that in that development we can find a bit more in the season and keep closing the gap."
