Its the one behind the spolier, is it some type of a VG?

most of the time thats a GPS / XM etc antenta. they mount the antena on alll cars but if u want XM for ex then it gets hooked up to the XM box. otherwise it's not conected.

just a fancy looking antenna.... probably low drag but no benefit adding it if you don't need it imho.

If you look closely at it, you might notice that the shape is a perfect Vortex Generator.
It functions as an antenna, but I'll bet that it also helps as a VG.
