The current issue of Roundel reports that BMW will, in a year or so, be offering a 3.0 liter petrol engine with bi-turbos similar to the 3.0 diesel. Not the twin turbo one, but the bi-turbo with dissimilar sized spinners. At the moment I don't remember horsepower figure accurately but 352 sticks out in my mind.
Am I behind the curve and you guys have already known about it, because I don't believe I have read anything about a turbo gas engine for new BMWs so it kind of surprised me.
