An eight speed transmission will be faster 0-60 than a 6 speed. Check out the actual torque multiplication in first gear, ie the first gear ratio times the final drive ratio. It is quite accurate to do these calculations to do a COMPARATIVE analysis. It would not make sense to try to derive the actual 0-60 time from analyzing these variables. That's why I said you have to compare only those numbers from the same publication. C&D is almost always at least 0.3 seconds faster than the BMW published time. You also have to look for differences in the cars tested, eg tire size. But all things being equal this analysis almost always works.
