Since the original conception of the M-Series, finding new ways to expand the boundaries of the existing BMW models has been the singal main purpose of the BMW M designers and engineers. Now the BMW X5 M and the BMW X6 M are the first all-wheel-drive models in the M-series family to offer remarkable performance, dynamic driving experience, athletic design, and premium quality. Both models are powered by a newly-developed 4.4-liter V8 M engine delivering 555 hp at 6,000 rpm and 500 lb-ft of torque from 1500 to 5,650 rpm. This new M engine is the world's first with a pulse-tuned exhaust manifold encompassing both rows of cylinders combined with high-performance twin-scroll twin turbo technology.For the X5 M and X6 M, engineers pushed the capabilities of BMW's intelligent xDrive all-wheel-drive system and the Dynamic Performance Control system to manage the power and performance potential of these two new vehicles. The special M suspension includes Adaptive Drive and the newly-developed Servotronic power steering. These features combine to push the limits of what was previously possible with a sports-oriented vehicle, and guarantee driving behavior characteristics of a BMW M product: incredible stability, precisely controlled steering qualities, and optimal powerful performance.
