Spy: Strange BMW

BMW currently tests a strange prototype in Germany that even the spies/photographers were confused of what they are seeing. From a distance it looks like BMW 2-Series Coupe, but from closer view it appears to be a model with a lowered roof, shorter wheelbase and smaller widescreen. Also some photos show a carbon fiber roof, hood and rear spoiler. 
All these modifications and especially the shorter wheelbase suggest a sports model and more likely to be the highly-anticipated Z5 which will be jointly developed with Toyota.
