When I talked with the Freightliner dealer I mentioned that Detroit Diesel (parent company or somehow affliated with Mercedes) lists the MBE 926 with 330 HP and 1000 lb-ft on their web site. The dealer indicated that this engine should be available in the M2 for the 2005 model year -- in fact, he said it was on his order sheets now.
More info on this engine is here:

Has anyone heard anything about this engine in the M2? Any recommendations?
