Apart from a car’s appearance, Lumma also likes to play with its engine. The X6 R package bumps up the 4.4-liter twin-turbo V8’s horsepower output from 575 horses and 553 lb-ft of torque to a whooping 750 horses and 723 lb-ft of torque. This combination of power and torque allows the BMW X6M to reach way over 186mph. All of this power leaves the rear in a set of four centrally mounted tail pipes; the outer two measure at 3.9 inches and the inner two measure at 2.75 inches. You will definitely give your competition something to look at as you pass them by with that unmistakeable rear.
