Another Grand Prix will pass this weekend without Renault having an F-duct on its 2010 car.
It was rumoured two weeks ago that the Enstone based team was on the verge of debuting the downforce-stalling concept, and team boss Eric Boullier confirmed it will appear "very soon".
Renault fell behind with the F-duct - pioneered by McLaren and now also run by Ferrari, Sauber, Red Bull, Williams, Force India and Mercedes - when it initially decided earlier this year that it would not waste resources on the innovation.
France's Auto Hebdo reveals that the R30s are not fitted with F-ducts in the Silverstone garages.
Boullier confirmed the news, adding that the concept is still being worked on and should make its debut appearance "very soon".
