This factoid will tell you a little bit about why the X5 M is so special: it has the largest front brakes BMW has ever fitted to any of their vehicles, ever. Those huge binders, 15.5” in diameter, are there to reign in the exorbitant velocities this newest addition to the BMW Motorsport family can achieve by tapping into the gargantuan power available from the twin-turbocharged 4.4-liter V8 under the hood. Even though no one would claim the X5 is a small vehicle, the 547 horsepower on tap mitigates any weight penalty the X5 may have by propelling it to 62 mph in an astonishing 4.7 seconds. While the forward progress the X5 M makes is easy to admire, it’s the agility of the big “Sport Activity Vehicle” that really sets the X5 M apart from the competition, with a laundry list of innovative M division suspension upgrades and driver assists to bring BMW’s signature sportscar dynamics to the X5. Whether it’s driving the X5 M or admiring its aggressively tweaked lines, the X5 M is a SUV that thinks it’s a sportscar, and has the moves to match.
