In exchange for a very slight decrease in PEAK torque, BMW has INCREASED the torque at higher (and lower)engine speeds. Greater torque at engine speeds above (and below) the speed for peak torque means HIGHER power at those engine speeds. What has been accomplished is a more flexible engine reponse has been created with a broader band torque curve. In principle this is an improvement and should produce a quicker, more responsive car. I do not know, however if one can really feel much difference between a 323 and a 325 because the increase in torque is not enormous, it is merelely incremental. The main point is that simply stating a peak torque/rpm and peak power/rpm only tells a small part of the whole story regarding engine flexibility.


Can someone with some knowledge of this subject explain. Can you re-tune the torque electronically? Why would BMW raise HP by air intake gains and lower torque?

Thanks
