However, Renault has found sizeable improvements to its power unit, with the French-works team bringing a new engine upgrade to the French Grand Prix not so long ago, and have reaped the rewards of the new PU ever since.
Renault is currently sixth in the constructors' standings, with McLaren 31 points above its rivals in the race for "Best of the Rest" supremacy.
The French team boss Cyril Abiteboul said that Renault needed to make "substantial changes" to its car to improve its performance: "It is funny because in my years at Red Bull, it was probably the opposite.
"The chassis would develop fairly quickly, but then the powerunit was behind. This year (with) the Renault, from the powerunit side, I've been really happy with the updates and progress.
"But hopefully (to improve the chassis), the next batch of upgrades we get is a bit more significant."
Ricciardo added: "I feel I would still be in the same position at Red Bull. Even though on paper, the results are better, whether I am getting podiums or whatever, it is still getting what I was getting the last few years.
"From a personal level, I know I have got more out of myself this year than I would have at Red Bull where I guess I would have kept doing the same thing with the same people."
