BMW is starting to explain itself with the development of its Progressive Activity Sedan (PAS), which is good because we've been having a little trouble placing the car in the lineup. We know it will be 5-Series->ke317 based, but we're still trying to figure out the need for the car. It seems like we're not the only ones, so BMW put together a little fun animation as a preview to what we presume is a Mercedes R-Class competitor.

One of the biggest mysteries that still remain is what will BMW call it? PAS? P6? 5-Series GT?
