Report: BMW M-Tuned 5 Series Diesel Could Pack a 516 lb-ft Punch

If you’re a fan of tire-shredding torque and Karl Diesel, perk up your ears: an attendant at a Dutch BMW dealer presentation has leaked some info from the meeting, confirming that BMW will make a hopped-up diesel 5 Series and that it’ll make quite a lot of power.

The car will apparently be called the M550dX. To make sense of that alphabet soup, it means that the 5 Series will have an M-tuned diesel engine and BMW’s xDrive all-wheel drive system. We’ve been told that the engine will be a variant of the 3.0-liter twin-turbocharged diesel engine used in the 530d and 535d, but will get three–yes, three–turbochargers. Final power output is allegedly close to 381 horsepower and at least 516 pound-feet of torque.

Take a closer look at the shots and you’ll find that the M550dX is filed under F10 and F11 model designations. Roughly translated from BMW-speak, it means that the torque-tastic 5-Series will be available in both sedan and wagon versions.

Production of the M550dX will begin in March 2012. Although BMW hasn’t confirmed if any version of the car (coupe or wagon) will come to our shores, it’s a safe bet that the wagon is a definite no, given the entire 5 Series range was replaced by the 5 Series GranTurismo in North America. That said, those seeking an uber-diesel with extra cargo space may not be out of luck: the M550dX’s engine may be offered in the likes of the X5 and X6 crossovers.

In the meantime, what do you think: does an M-tuned all-wheel-drive diesel signal another blasphemous move for BMW, or are you loving the thought of tire-shredding torque and respectable fuel economy? Let us know in the comments below.
