Virgin might introduce a so-called ’blown diffuser’ to its 2010 car later this season.
Previously, the new British team ruled out diverting resources for the development of an F-duct.
But driver Timo Glock told Auto Motor und Sport: "The (blown) diffuser is a possibility."
He explained that not working on the F-duct, which has been banned for 2011, is a "financial issue".
"It is not worth doing it for just a few races," Glock told the German publication.
Blown diffusers, the Red Bull-pioneered concept that was subsequently copied by other top teams, is now being seen even on the cars of smaller teams.
Williams debuted its version at Silverstone, Sauber at Hockenheim, and Force India’s version will be tested on Friday at the Hungaroring.
"We will analyse the findings and any data will be fed back into the programme for the second half of the year," said team boss Vijay Mallya.
The diffuser is credited for Ferrari’s improved pace in Germany, while McLaren is still getting the most from its version.
Auto Motor und Sport reports that the team is waiting on a supply of special anti-heat material to arrive from France.
"Only at Spa can we use our diffuser’s full potential," boss Martin Whitmarsh is quoted as saying.
