At the center of attention on all the M Performance Diesel vehicles (M550d, X5 M50d, and X6 M50d) is the fact that they’re equipped with a high-performance engine featuring three turbochargers. Twin-turbo setups are becoming increasingly common, but a tri-turbo? Thankfully the German automaker has released a video detailing the technology behind their new 381-hp, 546 lb-ft of torque engine.
The system basically consists of two relatively small turbochargers and one larger one. The smaller pair of turbos helps maximize acceleration and response-time, while pairing them up with the larger turbo ensures there’s plenty of additional power when it’s required. What’s especially interesting about such complicated forced-induction is how it virtually eliminates turbo lag because of the varying sized-technology.
Unfortunately for now, BMW has no plans on bringing this high-performance diesel engine to America, but one can hope that this tri-turbo technology finds its way into other BMWs.
Watch the video after the break.

It’s no surprise that BMW is extremely excited about the introduction of its four new M Performance Diesel models; so excited in fact that they’ve forgot to check the spelling of the word “precision.” We’ll overlook the irony of a spelling error on that particular word, and instead enjoy the epic sounds of BMW’s new, tri-turbo diesel models showing off just how sporty and powerful they are.
Unfortunately we won’t be seeing these M Performance Diesel models on U.S. roads anytime soon, but we can continue to hope that BMW might bring their 3.0L inline-six, tri-turbo setup sometime over to the States. With 376-hp and 545 lb-ft of torque with an eight-speed automatic, the M550d xDrive sedan and touring, the X5 M50d and the X6 M50d may be our wishes for years to come.
But for now, you’ll just have to settle with the video below. Even if it means wondering what the word “precison” is.
After months of rumors and speculation, BMW has made its new 3.0L six-cylinder, inline diesel engine official, packing what they’re calling M Performance TwinPower Turbo technology, which is a misnomer since it sports three turbochargers. The system works by using two smaller turbos to deliver more responsive power down low in the rpm range, with a large turbo to add top-end thrust.
The new diesel powerplant will put out 381-hp and 546 lb-ft of torque, exactly the same specs that have been rumored for months now. It also features BMW EfficientDynamics technology, including Auto Start-Stop function and ECO PRO mode.
The M Performance diesel models announced are the M550d xDrive sedan, M550d xDrive Touring, X5 M50d and X6 M50d. And as we stated in the title, none of these models will be making their way to America. All models will come with an eight-speed automatic transmission.
Performance figures for the M Performance diesel models are impressive across the board, with the M550d xDrive Sedan reporting a 0-62 mph time of just 4.7-seconds while the Touring model comes in at 4.9-seconds. The X5 M50d will hit 62-mph in just 5.4-seconds while the X6 M50d is a tad quicker at 5.3-seconds. What is even more impressive is that the M550d will average around 44-mpg while the X5 M50d will do 37.7-mpg and the X6 M50d will do 36.7-mpg.
And of course, with all these vehicles now sporting an M Performance badge on them, owners will get M-specific tuning of suspension, bodyshell mounting, engine and transmission mounting, springs and dampers, all standard and optional chassis control systems, and the Servotronic mapping for the hydraulic steering.
No pricing was announced for these European-only M Performance diesel models, but AutoGuide will be sure to check them out in person when they make their official debt at the 2012 Geneva Motor Show.

BMW held a dealer presentation in the Netherlands and a leak has rumors stirring that the upcoming M550d will officially come with 381-hp and 516 lb-ft of torque from its tri-turbo, inline-six diesel powerplant.
Even though the horsepower figure comes in lower than the early speculations of over 500-hp, the torque is pretty impressive. It also appears that the M550d will be AWD only with production beginning next March. It is not yet known if this F10-generation M550d will make its way to North America, but we could be seeing the tri-turbo diesel in other BMW models including the X5 and X6.
