Vitaly Petrov says he is hopeful that a series of major updates will allow Renault to return to the kind of form that saw the team secure podium finishes in the opening two races of the 2011 F1 season.
Petrov took a podium finish himself in the season opener in Australia before Nick Heidfeld secured a top three finish himself in only his second race with the team in Malaysia.
However, since then, Petrov has only scored on three occasions with a best finish of fifth, while Heidfeld has an additional four top ten finishes but none better than seventh.
It means that the team has scored 31 points from the past six races, having picked up 30 from the opening two rounds of the campaign alone, and is now only three points clear of Mercedes in the fight for fourth in the standings.
Many believe that ban on off-throttle diffusers from this weekend's British Grand Prix will hit Renault hard given the unique exhaust on the R31, but Petrov said he was hopeful that the performance of the car wouldn't suffer too much and that upgrades planned would allow the team to once again challenge for top three finishes.
"I hope it will still be a strong car because you never know how it will affect you or how it will affect other people," the Russian told ESPNF1
. "I hope other people will be more affected than us because otherwise we won't be so quick. So we're trying to work to be able to do something.
"At the beginning of the season we were really quite strong but then I think we lost some performance, maybe some other teams were improving better than us. But we're working on this; we know exactly where we lose time so we'll locate it for the next event so at the next race we should have a few big updates and we'll try and fight with them."
