Hi Gary,
In my XF (2011, XF-S Portfolio) they are def for real!
I enjoy the "theatre" of the startup as the vents rotate and the gear selector emerges.
All four vents blow cold (or hot) as desired, normally cold on my side, hotter on the boss's side. (Boss has her seat set to heat, mine to chill, mostly).
Have to say as well, that I love the way the demisting/de-icing just works in the winter, and have now got over the annoyance of the heating elements in the screen
Cheers
Jon
