It probably does make a lot less power than peak, but is more efficient at converting any fuel given to it into power, look at a typical bsfc chart:

Peak power for an engine is where torque*rpm is at a peak, probably up in the 5000 rpm range, but peak efficiency is where fuel consumption/power is at a minimum, around the 2500rpm range and 3/4 available torque.





Edit, also could use better understanding of the gearing change implementation too please.
