New video animation shows the coordination and interplay between the three turbochargers on the BMW M550d and X5/X6 M50d’s N57S tri-turbo inline 6 cylinder diesel engine.
We’ve posted the full tech specs of the BMW M550d sedan and touring, along with some more details, specs, and power output dyno graph of their TwinPower tri-turbo diesel inline 6-cylinder engines. Check it out inside at our official M550d info thread.
The first test drives of the all new BMW M550d xDrive model [official info/specs] are underway and here is the first video footage courtesy of Sport Auto. The M550d represents one of BMW’s new lineup of M Performance Vehicles (together with the X5 and X6 M50d and upcoming M135i), which bridge the gap between standard series cars and M cars.
The M550d xDrive features an inline 6 cylinder diesel engine good for 381hp and 546lb-ft torque.
Its official factory quoted performance stats puts it at 4.7 sec 0-62mph and a top speed of 155mph, and fuel economy of 44.8mpg (imp) / 35.84 MPG (US gallon). Unfortunately, the M550d will not be making it stateside.

BMW has released its second X6 M50d teaser. The company tries to raise the anticipation with this video dubbed “Step 2″. There’s no new information or new details shown, but BMW promises that the X6 M50d will “feel like a race car” and “deserve the M badge”. Guess we’ll have to wait and see if it actually can live up to these promises.
It’s teaser time again! Hot off the press here’s part 1 of “a new chapter: powered by BMW M”.
When you listen to the engine carefully you can hear it’s a diesel engine. At this point we can only speculate what this is about exactly, but if we were forced to do so we’d say it’s a promotion for the long-rumored M Performance Diesel models called X6 M50d ( and M550d for the F10) powered by a 3.0l inline 6 Diesel engine with no less than 3 turbochargers.
If rumors coming from a dealer presentation in the Netherlands prove true, this engine will make 381 hp and over 516 lb-ft torque. Complimenting the power plant is a dedicated M Sport Package and some other goodies. In other words, … CONTINUED
The rumor coming out of a BMW dealer presentation held in the Netherlands last week is that the previously rumored M550d will officially come in with 381 HP from its tri-turbo inline-6 cylinder diesel motor, far lower than the initial speculations of 500+ HP. But it will make over 516 lb-ft torque! Finally, it will be AWD-only, as speculated earlier.
This new tri-turbo diesel F10 5 series was previously confirmed to be coming, but a power figure was not yet known. That set off a round of high horsepower estimates because this model was supposed to have been tuned by BMW M.
Production of the M550d will begin next March, but it’s not yet known whether this model will be available in North America. Future applications for … CONTINUED
