Tech boss hopeful of overhauling Toyota
While still eyeing fourth place in the Constructors' Championship, Renault have made it clear that their focus has already shifted to their 2009 car.
The Anglo-French constructor are currently five points behind fourth-placed Toyota in the standings with five races remaining this season.
Nevertheless, with Renault outperforming their closest rivals in Sunday's Belgian Grand Prix - Fernando Alonso finishing fourth at Spa-Francorchamps - technical director Bob Bell says he is confident they can overtake the Japanese manufacturer.
"McLaren and Ferrari are clearly in front of us and so, if they have a good day, there are not many points left to go around," Bell said.
"So it's hard to close a gap of even five points, but I'm confident that we can do it and finish ahead of Toyota in the remaining five races to take that fourth spot."
However, Bell also confirmed that if Renault are to finish fourth at season's end, they will do so with so with only minimal further development of their 2008 car.
He added: "At this stage of the season, we are pretty much fully focused on the 2009 car, but we still have developments for the R28, which we will take to Singapore.
"After that we will examine whether there are any more chances to develop the R28, but we are very mindful that we need to concentrate the vast majority of our energy on the R29."
