The R.S.19 was launched online on Tuesday, with the 2019 livery also unveiled on a largely old auto at the team's factory.
Renault finished fourth past year, still a long way behind reigning champions Mercedes, Ferrari and Red Bull, but with its engines winning four races in the back of the latter team's cars.
Renault believes that they have made "substantial" progress with their engine for the 2019 season and believe that they are on track to start winning races by 2021.
Ricciardo has joined Renault from pit-lane neighbours Red Bull ahead of what is set to be another enthralling F1 campaign.
"It's the most productive winter we have ever had in terms of engine performance".
"On the engine side, yes we've had some issues and one issue is too many", he said. So I think to a certain degree when when you are in such a situation you are a bit more complacent with milestone and internal planning.
Abiteboul added: "We have the drivers".
Staff levels at Enstone have reached 750, including contractors, with a further 450 in France working on power units at Viry-Chatillon.
"On the chassis side, the Enstone side, we have the structure but it is going to take a bit of time before the structure can turn into a race winning auto". "And therefore being able to react quicker than before", Abiteboul said.
That roadmap should see the team fighting for podiums next season, but Abiteboul is hoping Renault can offer a glimpse of its ambitions to its front-running rivals in the next ten months.
'Last year a lot happened and it was a big decision for me, ' said Ricciardo. So we know that there is a direct connection between how short you can reduce your lead time and your competitiveness those are the sort of things that we need to do.
