Probably because it has xDrive. In high torque vehicles the ability to transfer the torque to the pavement though all four tires instead of just the rear two creates the ability to generate more acceleration and less tire spin resulting in lower 0-60 times. At higher speeds and in higher gears this is not a consideration because there is less torque and less torque multiplication and all the torque can be transferred to the pavement easily through just the rear tires. So, at higher speeds the most important factors in rate of acceleration are weight, hp, and drag coefficient, not low end torque or the presence of AWD. So, the 550i xDrive will definitely be faster 0-60 than the X5 5.0 and also faster than the rear drive 550i.
