At a glance, one might wonder what the intents of the X6M are. It’s too tall to be a sports car, yet its performance is undeniably exciting . The answer lies in the last letter of its designation, “M,” and one drive on most any surface will prove its heritage lies within. This twin- turbo V8-powered version with all-wheel-drive and an eight-speed automatic takes off from the line with the muster of cars half its weight. And, despite it being over 5,000 lbs, it will carve a turn and brake like you expect from any M-class BMW.
