Wednesday we saw the first glimpse of the Vision EfficientDynamics concept car destined for Frankfurt. Today BMW ‘s Frankfurt IAA Motorshow blog has released another teaser of the concept revealing a few more visual details. It is obvious that this is a design study and display vehicle for future drivetrains and use of materials, as the rear light displayed here would never make it to a production vehicle.

This is an official image from the same people that operate BMW-web.tv, expect more information and images to be released this Sunday.
