We've seen this exact BMW "M1" and its disguised carbon roof and huge fenders before, but we haven't seen it in motion on video. Bridge to Gantry spied it testing on the Nurburgring. Insert scalded pregnant cat metaphor here.

According to 1addicts, this is the BMW M1 expected to use a juiced-up version of the 3.0-liter twin-turbo straight-six. We're told power's reigned in just enough so it won't rival the M3 — except in weight gain. [1addicts]
