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

I read somewhere that the EffEyeAye plan to ban interactions between brain cells after Canada. During the Turkish GP, it was pointed out to M. Toot that a brain cell interaction ban was the only way the EffEyeAye rules writers could stay ahead of the designers. Look for an announcement from Pair Ree next week. :)

You'll find red bull are still quickest at 50-60% of the tracks, the McLaren special brake, Renault Mass damper etc etc still didn't slow these teams down enough to lose races generally.

RBR will win the WDC and CC.

Who last year ran the off throttle mapping? I know McLaren did after Silverstone. I don't recall RBR or Ferrari having that horrid off throttle sound. But that was many moons ago and I could very well be wrong.

Routing the exhaust outlets to boost the diffuser has been a standard item for a long time.
Sometime ago a new trend was set by FERRARI when they introduced the short top exit exhaust.
Last year possibly even the year before RBR started playing with engine off throttle mapping to boost the diffuser.
The off throttle engine mapping has been used in rallying for some time now.

"although such an appeal which was likely to come from Hispania wasnt forthcoming"

This is the same Hispania team who often have to go grovelling to the other teams to be allowed to race if they do not hit the 107 cut...so, unlikely to rock the boat too much then.

Also, how well will Vettel hold up against DiResta next year ?

I wonder how well Vettel will do in Q3 without his special boost ?
