Just the other day a very interesting spy shot of an orange mystery BMW model covered in a large grey tarp rolling out the back of a transport truck surfaced online. At the time it was believed to be the highly anticipated Z Vision Concept that was supposed to be unveiled at the upcoming Frankfurt Motor Show. After a bit of internet speculation the suspicions were denied by an official BMW spokesperson. According to the automaker, what we all saw was nothing more than a five year old design study that was being moved from the studio to a storage facility.

BMW said that they will indeed bring a concept car to the Frankfurt Motor Show, but it won't be the one from the photos. The concept that will be revealed at the German show will be called EfficientDynamics Vision, and will be on display next to the new 5-series GT and the X1 compact SUV. This new concept will combine the automaker's driving enthusiast feel with a much more efficient power train resulting in a low emissions fun to drive vehicle.
