Every road test shows the X5M beating out the Porsche in almost every category. I even saw a motortrend video that showed the x5 m do better in everything but 60-0 braking (x5m took 3 feet more to stop) yet at the end of the video they say the Porsche won by a hair. Still don't see how they arrived at that conclusion since their own tests show the BMW performing better.
