BMWBLOG learned from our sources that the new and first M diesel, the BMW X6 M50d, will run from 0 to 62 mph (100 km/h) in 4.9 seconds. Furthermore, we learned that the car will output 381 horsepower and 545 lb-ft of torque (740Nm).

The X6 M50d will come equipped with an innovative and unique engine, a tri-turbo six-cylinder diesel. The internal code for the BMW X6 M50d is FH81 and production will begin in April 2012.

The M division will offer the M50d with a revised front hood, included as option number 348.

But this is not all. We also learned that the “step-brother”, FBMW M550d xDrive will also be equipped with the same powerplant, running to 62 mph in 4.7 seconds. Thanks to the innovative diesel technology, BMW expects a fuel consumption of 6.3 liter per 100 km, or nearly 38 MPG. CO2 levels are 165 g/km.

The FV71 M550d will go in production in March 2012 and will be offered as an European only model.

Stay tuned for more exclusive BMW X6 M50d news in the upcoming weeks!
