The FIA issued a further Technical Directive this morning that in effect brings us back to where we were earlier this weekend, with teams restricted to 10% throttle opening under braking.
Renault and Red Bull have thus lost the advantage that rivals claimed they had been given yesterday.
After the letter was sent out this morning Adrian Newey and Christian Horner went down to visit race control to discuss it further. In fact this blog told Charlie Whiting that they were waiting for him…
Today’s TD26 says that from today the FIA will revert to the already issued TD22 and TD25, and states that any evidence on the matter that has arisen since Thursday is not admissible in terms of influencing the FIA’s decision.
The directive says: “In line with the requirements to provide acceptable SECU configurations to the FIA before the start of the British GP, ie before the start of the Event at 10am on Thursday, we consider any information provided after that time to be inadmissible for this Event.”
The directive adds that there is “an exception (of which every manufacturer was aware before the event) fired overrun will be permitted in FC04.”
The significance of that is that as Horner made clear yesterday Renault cannot take advantage of that for reliability reasons, whereas Mercedes can.
Update: During the lunchbreak today there was a hurriedly organised meeting of the Technical Working Group, chaired by Whiting, to discuss the issue.

All I know is what I read from yesterdays press conference transcript (ie nothing at all) but
If Renault genuinely needed to do (whatever the hell it is) in aid of reliability is it remotely believable that they would wait until theyd arrived at the track before submitting a request to Charlie Whiting/the FIA?
Exactly.
This is nothing more than teams playing games with the FIA now. They are so desperate to keep the advantages they have they are coming up with reasons as to why this shouldn’t happen.
As you say if this was such an issue to start with, why wasn’t it raised earlier? This ban has been known since at least the Spanish Grand Prix, these issues should have been raised a long time ago…
nice one from the FIA , 🙂
Um, no – RBR have been arguing their point with the FIA about cold exhaust blowng for reliablity of the Renault engine since as long ago as May.

It’s the FIA who can’t make a decision and/or keep their story straight.
