X6 M

As the more fashionable mid-size SUV brother of the BMW X5M, the X6M provides performance comparable to sports cars and features a slip-back shape that complements its high-energy personality. Hidden under the raised hood of the X6M lies a 617-horsepower twin-turbocharged V8 engine, tuned for extreme attacks. The astonishing acceleration is just one of the highlights of this super SUV; thanks to its precisely tuned suspension and near-perfect chassis balance, it also achieves handling that violates the laws of physics. Although the X6M's smooth silhouette is more eye-catching than its square-backed X5M brothers, it does pay a price in terms of rear headroom, cargo space and price.
