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.
