BMW explains how witchcraft works

Jeremy Clarkson once explained turbocharging by saying: “Exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.”

BMW has taken a slightly more technical approach to explain how their soon-to-be-universally-acknowledged-as-awesome tri-turbo diesel engine works. That’s the donk from the M550d/X5 M50d and so on.

In typical teutonic fashion the explanation is all fancy animation and clinical; there’s not even any sound. Just words and pictures. Come to think of it, and going back to Clarkson’s original theory, maybe the video below makes more sense in the second half. See what you think.
