As good of news as this is, I wont believe until I see it. I hate to be skeptical, but BMWNA has be on again - off again about bringing diesels to our market. Until these models are actually on the showroom floor I wont waste any of my time.
If they do bring them, I would bet they would only with the 8 speed transmission. It would be a perfect match for an engine that creates a vary narrow power band.
