Thanks for the reference. In additon to the additional weight of the 750i over the 550i, the 7 was tested with the 6-speed transmission. The 550i has an eight speed. This should cut even more time from the 550i. So, the estimated 550i times should be around 4.6-4.7 seconds which is just about what my E39 M5 was, ie 4.7 seconds. The 550i xDrive should be around 0.2 seconds faster.
