Renault are optimistic that they can force their way ahead of Merc GP in the battle for fourth spot in the constructor's championship.
The French outfit are currently 27 points adrift of Mercedes, but with Robert Kubica continuing to perform well above expectations and Vitaly Petrov improving with every race, the team are confident they can match the Brackley-based team.
"Our performance in Turkey suggests that our race pace is better than Mercedes, but they are just ahead of us on qualifying pace, and the same was true in Barcelona," said chief engineer Alan Permane.
"When I spoke to Robert after the race he felt that Rosberg was holding him up and that he could have gone quite a bit quicker. So it's down to us to make sure we do a better job in qualifying so that we can get ahead of them and exploit the full potential of our car," he added.
Permane believes that key to Renault success this season has been the consistency of their upgrades, with new parts implemented in Turkey and others ready for the upcoming Canadian GP.
"Our strategy of bringing updates to every race so far this season has been one of our strengths and is a testament to all the effort that is going on back at the factory," explained Permane.
"In fact we already have another version of the front wing in the pipeline, which will be available in a few races time and should give us another step forward on downforce.
"We expect to continue our current level of competitiveness in Canada where we will have further upgrades to the car. We also have good upgrade packages planned for Valencia and Silverstone, which will hopefully allow us to move ahead of Mercedes," he concluded.
