BMW is prepping the i3 and i8 concept vehicles for a full-on introduction at the Frankfurt show next month

We thought that was Vancouver in a video released by BMW a couple of weeks back showing the i3 and i8 concepts in motion in a cityscape.

It seems BMW has at least one set of functional i3 and i8 prototypes running around North America for promotional filming.

This time, the i3 and i8 have been spied live in the flesh on a photoshoot in Chicago. The windy city, indeed, you can hear it on the video.

Check out the second vid below too.
