FIA goes ahead with diffuser ban

The FIA goes ahead with moves to ban off-throttle blown diffusers
The FIA is to move ahead with its ban on off-throttle blown diffusers from the British Grand Prix at Silverstone next month.

According to the BBC, the teams were informed of the FIA's decision in a letter on Saturday morning in Montreal informing them that the part would be banned from the British race onwards.

The FIA has initially planned to ban the part at the Spanish Grand Prix only to give a stay of execution to teams that had argued that there was insufficient time to revise cars before the Catalunya race.

That in turn led to suggestions that teams without the part could launch an appeal in Monaco, although such an appeal – which was likely to come from Hispania – wasn't forthcoming.

As well as telling teams that the off-throttle diffusers will be banned from next month, technical delegate Charlie Whiting's letter is also reported to have told teams that stricter restrictions will be placed on teams next year – which could see blown diffusers banned altogether.

While the issues will be discussed at a meeting of F1's technical group next week, Mercedes team boss Ross Brawn suggested that the decision had already been taken and that nothing could be done to change Whiting's mind.

“Unless the teams can show a definite major problem with the approach that means it's not feasible, it will go ahead,” he said of the plans.

Read a Newey interview somewhere where he said the idea came initially from creative fix to a Renault engine problem that comes from the longer headers, off throttle exhaust blowing kept flow through the tubes eliminating stagnate hot air cooking the exhaust valves supposedly or something like that. If he can prove that, this could become flex wing part II as no one else seems to have mentioned or had this problem. Couldgo the opposite direction. That being said, I doubt RBR is that scared even if they do have to give it up given that all their nearest rivals are using the same 5cm loophole in the floor to blow the diffuser, fanboys will grasp at whatever straws they can to feel good though, as if the Rb7 was a giant turd otherwise, makes me laugh
