Renault have not made the podium in 11 races this season

Renault are fourth in the constructors' standings with just 33 points, compared to championship leaders McLaren on 138.

And with no realistic hope of a win in the remaining six races, technical director Bob Bell is now looking ahead.

Bell said: "The moment has come for us to focus on design and development and we're already focused intently on '08."

We have been exploring some very interesting new development paths Renault technical chief Bob Bell

The team's target for the rest of 2007 will be to beat third-placed BMW Sauber in the remaining races, starting with Sunday's Turkish Grand Prix.

But Bell insisted: "We will be working hard to extract more performance at the track from our most recent developments.

"We have always said that our problems this year would not compromise next year's programme, and that remains the case.

"We will have some minor aerodynamic upgrades in Turkey, and a new aero package (at the Italian Grand Prix) in Monza, adapted to the very low drag set-up we require there.

"The project is on time, and we have been exploring some very interesting new development paths."

606: DEBATE How will Renault fare in Turkey?

Renault, who lost double world champion Fernando Alonso to McLaren for this season, have yet to confirm whether their current drivers - Italian Giancarlo Fisichella and Finland's Heikki Kovalainen - will be driving for them again in 2008.
