On a YouTube channel with only this one upload, with the simple explanation "Found online. Sharing here.", we find this video titled "Investor Clip".  And at the 2:50 mark, we find the Brammo Side by Side Utility Vehicle.  What with all the drama with Brammo and all, this seems like it's a tease that links Polaris tightly. Of course, it could just be a fake, or a school project.  Like the Tesla Motorcycle video, we tend to see what we want to see.  See for yourself:

In case the video gets pulled in the future, here are a few shots from the clip.

Here, just for giggles, is the Polaris Ranger ETX:
