With the arrival of the third-generation X6, BMW is rolling out a new range-topping X6 M Competition model that offers more performance and special styling touches.
Compared to the 600-horsepower X6 M, the Competition version features 617 horses from the 4.4-liter twin-turbocharged V8. Torque for both models rings in at 553 pound-feet.
The X6 M Competition has a top speed of 155 mph, but increases to 177 with an available M Driver's Package that also includes a day at the M Driving School located in California or South Carolina.
