The Renault team is confident of taking another step toward the front in this weekend's European Grand Prix, thanks to updates the French squad will take to Valencia.
"We've got quite a nice upgrade coming, with a new front wing and a new floor, which we believe will take us another step forward," said Renault's chief engineer Alan Permane in a team preview.
Robert Kubica is also optimistic the upgrades will allow him to fight closer to the top of the field.
"The gap to the front of the field is not so big, but we still have to gain a lot of ground, and we can only do that if we keep pushing and keep working," he said. "We will have a new package on the car this weekend, and we hope that will bring us another step forward. But every team will be bringing updates, so it will depend how much they bring and how much they improve.
"In Valencia, anything could happen, and we need to wait and see if the order is shuffled and how we will perform compared to Mercedes."
Permane also praised the team's work so far this year, stating: "We have certainly seen an incredible rate of development this year. If we take the gap to pole position as a measure of how much we've improved, we've seen the gap steadily reduce race by race as we've developed quicker than some of our competitors," he added.
"With the updates we have planned for this weekend, that trend will hopefully continue."
