Renault evaluating rear wing system

With the French car manufacturer adopting an aggressive development programme this year, the team has been pushing hard in bringing upgrades to its cars at every race.

And although Renault has opted against using an F-Duct concept for a straight-line speed boost, the team is working on a similar idea to help stall the rear wing.

Team principal Eric Boullier told AUTOSPORT: "We definitely don't want to copy McLaren, but the idea could be good. However, until we have proved ourselves that there is a gain, then we will not do anything about it.

"We are looking at the idea, but that is because we are looking at many, many different ideas and many things. But we will not copy McLaren.

"We will not do a copy as that will be a waste of time, but we are looking something with a similar concept - like a blown wing."

McLaren and BMW Sauber are the only teams to have raced fully-functional F-Ducts so far, while Ferrari, Mercedes GP and Williams all began evaluation of 'blown wing' concepts in China this weekend.
