As we just hit published on our BMW M3 tri-turbo engine story, another related report comes forward from our sister magazine BimmerToday and Motor-Talk. According to them, a label for brake pads received by a parts supplier indicates that the new 5 Series family may get a new member,  M550d model with the xDrive system.

The “550” badge seems to point to the use of the new Tri-Turbo diesel engine that will power the 2012 X6 xDrive50d and 750d limousine. The new power unit retains its inline-six architecture with 3.0 liter displacement and three turbochargers. The power of this engine will peak around the 400 horsepower mark.

The diesel powerplant can be positioned in a way as an alternative to the top 550i model and its 407 horsepower. The M Sport package featured in models possibly sports slightly different design cues to further distinguish the M550d from the “regular” 5er M Sport.

BMW M550d xDrive Etikett Motor Talk 655x435We expect the new tri-turbo diesel engine to debut next month at the Frankfurt Auto Show in all variants we reported on before: X6, 6 and 7 Series. It remains unknown at the moment whether the new engine can be homologated for the US, but European customers will get to enjoy them starting in Spring 2012.

  1. The word “impossible” does not exist in BMW…

    Or could it actually be an M5 all wheel drive diesel?

    Yes, BMW registered a trademark “M 50d” quite some time ago. For top-end performance diesel models.
    So, yes, M_50d models are coming (eg. 5er, 6er, 7er, X5, X6 etc) in the next months. With 6-cyl engins, not 8!
    And as you can see: 523i (I guess with some 218PS?) & a hybrid version of 5er are also coming. :)

      Thanks Tine, always appreciate the input.

      We did break the news on the tri-turbo diesels, so doesn’t surprise me at all. At IAA, we will see at least 2 of these models.

    Are we going to end up with more turbos than cylinders?

    Right, after the FWD cars, the turbo and AWD Ms, BMW proudly keeps destroying its image : a M Diesel car…
    beside, If BMW doesn’t or can’t sell this version in the US and China, it’s going to be a failure.
    Unlike US drivers, EU owners are not keen at all of big size luxury muscle cars, maybe because they realised long time ago that this kind of cars are irrelevant – a M3 will always beat a M5 of the same generation.
    Worse, it wouldn’t even be a show case or an image car : if BMW releases such an engine, it would certainly be made available in the X5/X6.

      Actually BMW customers like to keep up with innovation and like to be ahead of the rest.
      Customers might be having second thoughts regarding V8’s etc , want to downsize but still want Performance of a V8 but not necessary the fuel bills that accompany it.
      So with Performance and efficiency being it’s greatest strengths. It provides a platform for the customer who wants to downsize without complete sacrifice.

      We certainly noticed this with the Six Cylinder , Petrol and Diesel. That customers were coming from larger V8 models both from BMW and major competitors. 
      The Tri-turbo Diesel will generate a grand following – It is everything that is great about a BMW engine.

      Its not ///M, its M-Package, like 535i with M-Sport package.
      If this diesel comes into market in 2012 with mentioned ~400hp, I`ll start to doubt that BMW is a company from this planet.
