Next spring, BMW will expand the vaunted M lineup with the addition of a new high-performance diesel-powered 5-Series model, according to a report by The Detroit Bureau.
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 560-hp new gas-powered BMW M5. It is expected to have a power range of between 500 hp and 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.”
BMW Motorsport GmbH was founded in 1972 mainly to focus on the carmaker’s racing program. BMW Motorsport’s first racing project was the BMW 3.0 CSL. Thanks to the overwhelming success of the BMW 3.0 CSL and other vehicles in racing events as well as thanks to the growing market for high performance sports cars, BMW Motorsport eventually decided to make such cars available to the public.
The first of these official M-badged cars was the M1, which was revealed to the global public at the 1978 Paris Motor Show in 1978. Since 1978, the M division has sold more than 300,000 vehicles globally. BMW Motorsport changed its name to BMW M in 1993.
