Video: BMW X5M and X6M Hit the Track and the Road

Time to get a taste of BMW's new X5M and X6M in action with the first official video clips of the sporty crossovers that are powered by a new 4.4-liter twin-turbocharged V8 engine producing a maximum output of 555 horsepower from 5,750–6,000 rpm. The X5M and X6M videos include driving footage on the road and on the track as well as beauty -well, at least not in the literal sense of the word...- shots of the vehicles' interior and exterior.
