There doesn´t exist any possibility that there would be an electric supercharger ... this is only an misunderstanding of the patented BMW eTurbo-system, in which the regular turbos could be driven by an electric engine over an clutch at low rpm were the engine doesn´t produce enough exhaust pressure to drive the turbos good enough or to reduce the turbo lag.
