Slap a twin turbo charged 4.4L V8 into any vehicle and you have our attention but inside the BMW X6 M it becomes a show stopper. This completely uniquely styled SUV produces 617 HP and 553 lb-ft of torque. There is no doubt you will be the envy of the block in this incredible vehicle. With blistering acceleration and sporty feel, the X6 M puts the Porsche Cayenne Coupe and Mercedes-AMG GLE-class in the rearview mirror.
