Renault's performance this season has taken a few steps up compared to 2016, but Nico Hulkenberg still has a 'big list' of things he doesn't like about his RS17.
The German driver brought the French manufacturer its first points of the year last Sunday in Bahrain when he finished the race ninth.
While the result and the team's performance in qualifying validate its step forward, Hulkenberg is convinced there are many areas which can see improvement.
"I mean it's all relative," Hulkenberg explained
" People that are 15th or something, it's probably much worse, but I don't care.
"I'm in the car and obviously I have to point out to the team where the problems are and where we need to focus on and develop.
"It's good that we have that pace but we still have a lot of areas to work on. It shows that there is good potential in this car and that the base package is pretty good."
As a manufacturer's works driver, Hulkenberg enjoys his current working environment and the potential for success it embodies.
But the 2015 Le Mans winner says it's still early days as Renault hopefully returns to its past F1 glory.
"I think there is a good structure in place," he says.
"No big deficits anywhere. I think there is always room for improvement everywhere, it's all in the detail. So many different areas teams nowadays look on and are working on.
"It's just so much work, and effort that goes into it. It's really hard to catch up and get there."
