The BMW X6 M is one hot piece of German engineering. This $100,000 performance SUV has an absolutely monstrous 4.4-liter twin turbo V-8 capable of producing an astounding 567 horsepower and an insane 553 lb-ft of torque. In other words, this baby hauls ass and we would drive one in a heartbeat. Also, if we were lucky enough to own one of these mean machines, we certainly wouldn’t feel the need to add any extra modifications. The car is already perfect as it comes.
