Renault boss Cyril Abiteboul believes the team's commitments to returning to the front of the grid is clear in the changes it has been making to every level of its operation.
Renault finished fourth previous 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.
Abiteboul said progress on the engine over the European winter had been "substantial". We don't want to stop here, it's not enough, we want to fight for more.
Former Red Bull driver Daniel Ricciardo joins Nico Hulkenberg for 2019.
"On the engine side, yes we've had some issues and one issue is too many", he said. "We are aiming for zero DNFs (non finishes) related to either the chassis or the engine".
"If we made a decision to get all of you here today it's really because we feel ready", Abiteboul said.
Meanwhile new recruit Ricciardo stated that his goal was to bring some "positive energy" to Renault to help motivate them to greater things.
"We have worked hard on the ERS [energy recovery system] and worked a lot on the ICE [internal combustion engine]". We know that it will take a bit of time, so what will happen next?
"We have confidence that we have a good platform".
The Enstone roll-out did not feature Renault's 2019 R.S.19, as the presentation - as Haas and Williams - showcased the team's relatively unchanged livery on last year's auto, although the modified R.S.18 displayed a 2019-spec front wing.
"We are now becoming a big team", the Frenchman said.
But Renault's solid line-up will be sparing no effort to reduce the yellow squad's gap with Formula 1's trio of front-runners, Mercedes, Ferrari and Red Bull.
