Mar.25 (GMM) A third major team has joined the crusade against Mercedes' so-nicknamed 'W-duct' innovation.
Until now, only Red Bull and Lotus were pushing hard for the FIA to ban the drag-reducing system that Britain's Sky television is calling 'Super-dooper DRS'.
Auto Motor und Sport reports that Ferrari has now joined the anti W-duct group, providing a new argument about why a driver is not permitted to activate a separate system by pressing the 'DRS' button on the steering wheel.
"So far I have heard nothing that convinces us that it is illegal," the FIA's Charlie Whiting is quoted as saying.
He is not, however, ruling out an eventual change of heart.
"As we understood more about how the mass damper worked and as more arguments came onto the table, eventually we could no longer turn a blind eye," said the Briton.
Still, Whiting is not expecting a post-race protest in Malaysia.
"I think everyone understands that that is not good for the sport," he said.
So far, McLaren is staying out of the fight, with Auto Motor und Sport believing that Martin Whitmarsh "will not wage war against his engine supplier".
Nonetheless, Mercedes boss Ross Brawn is more than unimpressed with the warring trio.
"There are a massive amount of things we do with DRS, so to pick on one thing and say 'We don't like that very much as we haven't thought about it', is wrong," the Briton charged.
