e36 328i vs e46 330i vs e90 330i

IMHO an auto e46 330i will humble a manual e36 328i. The 330i's power & torque deliver on take off makes the 328i look sluggish....

Ok, so i have been looking around and testing things with friends.

I have found that my stock e36 328i put out ~140kw on the fly, and ~118kw on the wheels. A friends stock e46 330i puts out 170kw on the fly, and on a dyno he put down 113kw (i have seen other 330i's with similar figures). Another friend has an e90 330i, which is 200kw on the fly, but only put down ~121kw to the dyno. I checked the Rob Green site and they have some dyno sheets there that correlate to these findings.

Can anyone explain why there is such a high loss of energy in the later BMWs?
