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.

A second video has now been unleashed on the Internet, with the same blurring of the headlights, taillights and rear badging of the upcoming X6 M Diesel. By now no one believes it’s anything else other than that, and now it’s just a matter of time before the clear picture comes into focus and whether or not this X6 M will be breathing through a tri-turbo, six-cylinder diesel powerplant.
Check out the new video after the break teasing the upcoming BMW X6 M Diesel.
