Next spring, BMW will expand the vaunted M division with the addition of a new high-performance diesel-powered 5-Series model, according to a report by TheDetroitBureau.
This triple-turbo V-8 oil-burner set will be used in various other BMW vehicles such as the X-series sport-activity models. Sources confirmed plans of a diesel M to TheDetroitBureau.com and gave details of how BMW plans to tap into the potential of the high-mileage technology.
BMW aims to utilize different new technologies, including the triple-turbocharging system that’s designed to eliminate turbo lag.
It’s likely that the new model will receive the uncommon designation of either BMW 550dM or 550dXM, which refers to its all-wheel-drive system.
This is a rare occurrence as most models that are built by BMW’s sub-brand bear the vaunted “M”. The alternative nomenclature would be for this unusual powertrain to be reflected under the hood of the 5-Series BMW.
A small turbo will be used by the 3.0-liter straight-six diesel to immediately increase boost for launch as two larger twin-scroll turbochargers will then spool up for a better speed performance.
The basic engine is similar to the existing BMW 3.0-liter diesel but it will receive major tweaks, such as a new cylinder head. It will use various advanced technologies such as direct injection and BMW’s Valvetronic system that are meant to maximize the function of intake and exhaust engine valves.
Sources say that the 550dM will have lower output than the 560hp new gas-powered BMW M5. It’s expected to range from 500 to 550 hp. Torque is expected to surpass the new M5’s 500 lb-ft and may be even higher than 650 lb-ft. A senior BMW official said that the model will have to be all-wheel-drive “otherwise you’ll be spinning your tires all day.”
