Despite having previously driven with the class-leading Mercedes engine in 2018, Ocon said he noticed a step-up with Renault's 2019 unit.
"It feels good. Obviously there's always a lot that you can improve," he said of the R.S. 19.
"But the engine is also something new for me since a couple of years. Good power. Then, of course, the balance, you need to always work on it, it's never perfect until you get the touch on it. I think we have a solid base that we can continue."
