Since the F01 has been around for a few years, C&D has plenty of 0-60 test data:

4.3s - 2011 B7 (4710lbs)
4.3s - 2011 B7x (4886lbs)
4.4s - 2010 760Li (5150lbs)
4.5s - 2011 7AH (4807lbs)
5.1s - 2011 740i (4381lbs)
5.1s - 2010 750Lxi (4980lbs)
5.2s - 2009 750i (4760lbs)
5.2s - 2009 750Li (4475lbs)
5.3s - 2011 750Li (4602lbs)


Road & Track didn't do as many tests, but they were faster:

4.3s - 2011 B7 (4795lbs)
4.3s - 2011 760Li (5000lbs)
4.9s - 2010 750i (4600lbs)
4.9s - 2009 750Li (4735lbs)


Now none of these acceleration numbers are guarunteed for any particular car. There are a few of us over in the F10 forum that have taken our Dinan cars to the dragstrip and our results have varied quite a bit. Track run #2: 1/4 mile times w/ Stage III

I suspect if we had taken our cars to the track while they were still stock we still would have seen variations in results.
Stock m5 has been tested at 4.2 - 4.4, GRIP tests them here @ nordschleife first hand. Documented, approved by M rep.
Obviously even a simple tune can get this car down to under 4s, but that is NOT stock.

And you're forgetting the major weight difference on the s8 - deliberately?I won't even mention the torque trustability.
