Before we go any further in depth into the BMW M550d, X5 M50d or X6 M50d, just know that all three models will not be coming to North America.

Rumors of a tri-turbo diesel I6 from BMW sounded like a fanboy’s wet dream being propagated as truth, but apparently it’s real. The new 3.0L mill makes 376 horsepower at 4,000 rpm and 545 lb-ft of torque from 2,000 to 3,000 rpm. An 8-speed automatic and xDrive AWD put the power down, and the 550d can hit 60 mph in 4.6 seconds. A wagon version of the M550d will be available alongside the X5 and X6 variants. BMW quotes fuel economy figures as high as 36.7 MPG (in US gallons) but didn’t specify if it was city, highway or combined consumption. Check out the press release below for more information.

The BMW M Performance Automobiles.

    It’s torquetastic!

    I’m glad to see BMW introduce performance diesel models. 3 turbos is over the top but that is BMW. Perhaps this is a precursor to challenging Audi’s success with diesel Le Mans prototypes.

    Now I’m waiting for even more ridiculous model names along the lines of Z4 sDriveM35dis.

    While the power and torque are good, diesel engines tend to make cars nose heavy which will mean that these “M” cars are for straight line drag racing only.

    BMW is also risking diluting the M brand by slapping the M logo on any overpowered SUV or diesel sedan.

      Re: brand dilution

      They are trying to expand the M-brand. We will all know what the real M cars are. Unfortunately we will have to deal with the douchebags who will be fooled by body kits, M badges and long model numbers.

      6 cyl. diesel is nose heavy but petrol V8 isn’t? Are you sure about that nose heavyness theory? I think all the alu/carbon/alloy/plastic parts BMW puts into front part of it’s new cars esp. to reduce weight and balance cars better should take care of any such problems.
      I don’t remember seen any comments that old v10 or new V8 M5 are nose heavy.

        Diesels typically require an iron block, and iron is almost 3x heavier than aluminum. (MB developed an aluminum block diesel engine in 2005, but I don’t know if BMW is going the same route.)

        All BMW diesel engines introduced since 2007 use an aluminum block. The N57S used here is no exception. (The N57 3.0L I6 was introduced in 2008… this is just a high performance tri-turbo version)
        The American-market 335d and X5 35d use an old-school iron-block M57 – European X5s are available with 258PS single turbo (30d) and 313PS twin-turbo (40d) versions of the N57.
        The 335d soldiered on with the old M57 engine in Europe too, while 5/6/7/X3/X5/X6 all already had their N57s – I guess the F3X is going to change that…

      I know a guy who’d love to glue a M550d nameplate to the back of his tuned Dodge Cummins pick up…

      In the American Le Mans Series, the BMW M3 GT cars (front engine V8) got a special exemption to move the transmission from the front (just behind the engine) to the rear (as a unit with the differential). This also allowed the V8 engine to be moved back in the chassis about 3 inches. So, for those cars, before being prepped for racing, nose heavy was indeed a problem.

    The original owners of these M-series TTT-diesels will only buy them for the novelty. When that wears off, it’ll be the next owners who live the nightmare of maintaining and repairing them.

      Hasn’t that been increasingly true of German cars in general?

      I doubt they will be any more expensive to maintain than the other current M cars. And they will probably use 1/2 the fuel. Which at $10/gal is significant, even for someone who can afford the price of entry. Plus the possible CO2 tax savings cannot be dismissed in Europe.

        +1 on the tax savings. Them gummiments prefer soot to soda bubbles over there.

        I do wonder though, how much more carbon a maximally efficient 375 hp gas engine would use, if it’s price was no more of an object than in these Bimmers. That’s power waayy short of the ancient small block in the ‘Vette.

        And as far as torque go, us simpleminded ‘mericuns do get to spec gearboxes on our cars, and some of us even know how to use them.

    alloy block does save weights, is more for a good time but not long time.

    Sadly they’re not coming to this side of the Atlantic!

    There are a lot of misconceptions & noise here about BMW diesel block. This particular block is an evolution from N57 which is is a family of aluminium, turbocharged straight-6 common rail diesel engines.

    Do any of you even know what “nose heavy” means? (Try Audi)

    Do you know both 335d & x5 xdrive 35d are 49/51?

    Instead of pulling crap out of your rear end, some of you shall know BMW describes those”heavy engine block” as : … inline 24-valve 6-cylinder Advanced Diesel engine with aluminum engine block…

      “Do you know both 335d & x5 xdrive 35d are 49/51?”
      You just quoted the last two current BMW diesels that still have the iron block M57 – and still these are 51/49.

        Mirko,

        I thought those were iron block. According to BMW’s own spec:

        3.0-liter, 265-horsepower, 24-valve inline 6-cylinder dual overhead cam (DOHC) Advanced Diesel, TwinPower Turbo engine with aluminum engine block and third-generation piezo common rail direct injection.

        That is really weird. The North American BMW diesels use a M57Y – the last M57-family engine. When they came out with the M57 in 1998, BMW’s own technical literature stated:

        M57-specific features:
        •In-line 6-cylinder engine with cast-iron crankcase
        •High-pressure fuel pump
        •Plastic cylinder head cover
        •Plastic manifold based on two-shell weld technology

        http://www.scribd.com/doc/56011951/BMW-Common-Rail

        So either BMW completely changed the block for the M57Y compared to all other M57-family engines, or the BMW USA website is wrong.

    What type of model name is POSSW & why did they mount the badge upside down?

    M badge, diesel, automatic only, AWD? Bleh. That is not an M car.

      AWD is necessary for putting all that power down, though it seems the UK will get an optional RWD M550d.

      An automatic transmission is necessary because most drivers won’t be able to launch and drive the car properly with so much excessive torque available. Also, I don’t think BMW has a manual transmission available that is capable of handling that much torque. And developing one for this car is a waste of resources (most M5s will be sold with the DCT).

    I prefer this torque beast to M5 for daily driving. This beast will probably never reach the shores of NA.

    “376 horsepower at 4,000 rpm and 545 lb-ft of torque from 2,000 to 3,000 rpm”

    I am pretty sure that there are peterbilt’s without that much spec.
