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.

Rumors are now spreading rampantly since BMW released its teaser video of the first-ever BMW M Diesel in the form of their X6 crossover. It is now widely believed that the X6 M50d will come with a tri-turbo, six-cylinder diesel powerplant pushing out 381-hp with a healthy 545 lb-ft of torque.
The folks over at BMWBlog are also reporting that the X6 M50d will go 0-62 mph in 4.9-seconds and that production of the model will begin April of 2012. An option for the X6 M50d also leaked out; the M division will also offer a revised front hood.
Perhaps even more interesting is that BMW’s M550d xDrive will feature the same powerplant, making it go 0-62 mph in just 4.7-seconds and could get 38-mpg. The M550d is expected to go into production in March 2012 but will only be offered in Europe. Whether or not the X6 M50d shares the same fate is unknown, but given how slowly diesels are being embraced in America, we shouldn’t hold our breath.
