Sources close to BMW have told us the maker is working on a new M1 supercar, perhaps with the styling cues of the Vision EfficientDynamics concept car from Frankfurt, but probably not its diesel-electric powertrain.

Now what are we to make of this, evidently an original BMW M1 skinned in psychodelic-camo-top-secret-prototype livery and parked along a Munich city street? Serious viral marketing campaign or half-witted YouTube video shoot?
