BMW to introduce diesel into their 'M' line

[Wretched]

Rumors of the diesel M have been circulating for several weeks, but TheDetroitBureau.com has confirmed details with a variety of BMW sources who say the maker wants to prove out the potential of the high-mileage technology – taking advantage of a variety of new technologies, including the unusual triple-turbocharging system meant to eliminate even the most minor turbo lag.

The new model is likely to get the unusual designation of either BMW 550dM or 550dXM, the latter referring to its all-wheel-drive system. With rare exception, most models produced by the Bavarian maker’s performance sub-brand flash the vaunted “M” first and foremost. But the alternative nomenclature would reflect the unusual powertrain under the hood of the 5-Series BMW.
