BMW Launches First Video Tease for Vision EfficientDynamics Sports Car

The BMW Vision EfficientDynamics is a new "green" sports car concept that will be officially revealed in a few weeks time at the Frankfurt Motor Show. Until then, the Bavarian automaker is happy to tease us with this video that contains some driving footage of the concept without actually showing the car itself.

However, towards the end of the film, there's a vague shot of the concept and our guess is that it shows part of the car's rear-end design.

Allow us to remind you that earlier this month, a set of spy shots, allegedly depicting the Vision EfficientDynamics concept, made their way into the net. That particular vehicle, which appears to be a four-door coupe, may very well be a entirely different model than the one teased in this official video.
