In this latest BMW video in the i8 series, the German automaker zeroes in on the aerodynamic qualities of the i8.

"With this BMW TV series you can get a closer look at the BMW i8. This time you can get more information about the Aerodynamics of the BMW i8."

One of the i8's most unique features is out back where the rear fender doesn't quite meet the rear glass, thus creating a sizable gap.  It's an unusual form that we've never seen before.  The reason for this design element is explained in the video above.
