HRT is apparently no longer pushing so hard to have exhaust blown diffusers banned in 2011.
At recent races, the Spanish team has been threatening to protest the results after the FIA vowed to crack down on the technology that has moved into the realm of outlawed ‘moveable aerodynamic devices’.

But ahead of this weekend’s Canadian grand prix, Hispania announced that one of their developments is a “new exhaust system”.

It emerged during morning practice in Montreal that, in collaboration with engine supplier Cosworth, the system is indeed a blown exhaust.

That means that the only team not running a blown exhaust of any type at present is HRT’s nearest competitor, Virgin, who according to Auto Motor und Sport will not be ready to re-introduce a similar layout until Silverstone.

The FIA still intends to push on with the ban, however, with talks scheduled for the technical working group meeting next Thursday.

Asked on Friday about speculation of a ban, HRT’s technical director Geoff Willis told the BBC: “It’s going to be very tricky.

“There may be a solution for 2012, but what we do for 2011 is going to be very difficult in terms of what’s fair for everybody.”
