It is permanent in the sense that the system is always on, not in the sense that it permanently sends a significant fraction of the power to all four wheels.
VW said:[...]is based on an electrohydraulic multi-plate clutch (Haldex)
Does anyone even bother to read the text beneath the pictures?
As far as I know permanent all-wheel drive != Haldex system.
If they were going to put the RS moniker on one of their SUVs I'd rather it be the Q7. If you're going to make a stupid silly performance SUV may as well go all-out crazy. BMW didn't throw an M badge on the X3.
