SMG/Manual in 6er = 3.23; in 545 = 2.93
Auto: 6er = 3.46; 545 = 3.38
I am not so convinced that the ECU maps or SMG software are different but could be wrong.? I think performance differences are weight & gearing related for the minor differences reported.

[/quote]Digging around on BMW NA, I found the following:550i0--CD = .29, and lbs. = 3,814
650i-CD = .30, and lbs. = 3,814
I thought that earlier figures gave the 650i a slight weight advantage. And, I thought that the same for the 545i and 645i. Maybe the rear-end ratios are slightly different for the 2 45s and the 2 50s--thus, expaining the very small performance differences. But, CD gives a tiny advantage to the 5 series cars.

[/quote]Edit: BMW Germany shows:
Rear end--650i steptronic coupe--3.38
Rear end--650i steptronic cabrio--3.46.
I am beginning to think that the publicized performance difference is bogus--designed to make the more expensive and sportier car appear slightly faster. Or, more innocently, the difference could actually have been produced in a test, and BMW did not think about how odd the difference would appear on paper.
