Kubica hopeful of keeping momentum

The Pole finished on the podium in Belgium a fortnight ago - and the whole team acknowledged that that result was helped by the introduction of its F-duct for the first time this season.

And although the team is unsure yet if it can run it in Monza, Kubica is still hopeful that the outfit can deliver another strong race.

"I think this will be a very interesting weekend to judge the performance of the cars," he said. "Spa was a good example of how powerful the F-duct can be and we were immediately more competitive and closer to the front when we fitted it.

"The effect will be less powerful in Monza because the cars run with less drag, but there will be still be an advantage, so we need to see which teams use it and if we are able to as well. This circuit can sometimes throw up some surprises, so I prefer to stay cautious when it comes to predictions.

"But if the car feels as good as it did in Spa, then there's no reason why we won't be competitive in Monza."

Although most of Renault's effort is being focused on its 2011 car, the team is still hoping to bring further updates to its R30 over the remainder of the year.

Technical director James Allison said: "By this stage of the season any sensible team will be spending most of its time working on next year's car, and we are no exception. However, we've still got a few more upgrades to come before the end of the season, although it's fair to say they will not be as significant as those we were bringing to the car at the start of the year."
