"...rely on the FIA..." well that would be a mistake then. Just how many times in the recent past have the FIA given a decision, only to reverse it not long after?

Mercedes are openly saying that from the sound of the engine (analyses) they believe Red Bull might be breaking the rules.
Sauber says mclaren exhaust is borderline.
And as everybody knows both Red Bull and Lotus say that Mercedes rear wing F duct is illegal.

As long as the last 100mm of the exhaust tail pipe is positioned within the FIA designated aria and as long as the diameter of the pipe and it's angle are within the rules the exhaust will be passed ok by the FIA, whatever they manage to blow is immaterial.
The rear wing F duct system is a different matter altogether, is it acceptable for the driver operated DRS mechanism to have a secondary function?

sunny. the drs button rule says that the buttons PRIMARY purpose is to open the flap. thus merc say that it can have a secondary or even tertiary purpose, and is thus legal. protesters say that a driver operated aid, other than direct drs operation, is banned. who is right?

re mclaren exhaust. as discussed before, any exhaust that has a direct effect on aero is supposedly illegal. it seems that mclaren exhaust may have more effect than ferrari or bulls. not quite sure how, but merc and lotus believe that it is illegal. again, who knows?

Richard, “any exhaust that have an effect on aero is supposedly illegal” I don't think so, what was banned was the exhaust blown diffuser and the off throttle engine mapping.
All the exhaust systems we've seen so far comply with the new regulations, we are not in a position to be able to say how much aerodynamic influence each individual system has, nor is it anything that interests us, as long as they comply with the rules. “Charlie Withing”
Re the rear wing F duct, in my opinion it is triggered by the driver via the DRS.
The Lotus front ride height was also going to be triggered by the driver via the brakes.
The off throttle engine mapping was also been triggered by the driver via the accelerator pedal.

sunny. mea culpa. looking at the regs, there is no reference to a specific ban. i am not sure where i picked up the info from, but the issue has been raised by various teams. maybe it was a verbal intention that the exhaust could not be used to affect aero. so i dont know why merc could be claiming that mclaren exhaust is illegal?

The top teams while having to comply with the FIA limits as to the position of the exhaust tail pipe are all trying to direct the exhaust gasses to the diffuser but now mostly to seal it, they are doing this by the shape of the bodywork, high speed air coming from on top the bodywork will force the exhaust gasses downwards, the exhaust gasses will stick and follow the bodywork as the high speed air will also do.

I would like to ask/invite the person who disagreed with Richard “by pressing the disagree button” to feel free and join in this discussion, his opinion/contribution will be most welcomed.
