BMW has published a teaser video with the X6 M50d that show’s the M division’s new crossover being put through its paces on twisty public roads. 
Although the automaker did not specify the badging for this model, nor did it give any hint regarding its powertrain, various sources are saying that we’re talking about a diesel version backed by a 3.0-litre unit rated at 380 horsepower and 700 Nm of torque.
BMW has intentionally blurred the front and rear sections of the new X6 M50d but as you will see, it is still possible to notice the fact that this new performance crossover will feature tweaked headlights and taillights.
