Nico Hulkenberg has said that Renault must make another “big step” to start closing in on the top three teams.
The Enstone outfit finished best of the rest in the 2018 season to continue their positive momentum since returning as a works team.
But Hulkenberg is far from settled and wants to see even more progression, but that will be difficult to judge with new aerodynamic regulations on the way.
“We have to [keep progressing],” Hulkenberg said.
“But it’s always really hard – it’s all speculation. We know what we do and I know it sounds not bad, but we’re in the darkness as to what the others find.
“Obviously the new front wing is kind of a soft reset for next year, as it’s quite different for the cars. So it’s really hard to gauge, but of course that’s where need to go, what we need to aim at.
“We need to eat a lot of the gap away and eat into it. As a factory team, we need to aim at making a big step.”
That is not to say that Hulkenberg has not been impressed with some of the development been made, but there is still room for improvement.
“I think we’ve made a lot of good progress in a lot of areas, especially in team structure and putting the team in the right place to grow and to build in the next two years,” Hulkenberg added.
“But on the technical side, development side – just on the car – this year was not quite to our ambitions and what we were looking for. So that’s something we have to work on and get better at next year.
“But I think overall: last year P6, now P4 – I think that’s a healthy and good development.”
