That's like saying the N55 is "working its ass off" because the old E46 328 2.8L is also an inline 6 but makes less power. The comparison has no merit in terms of longevity conclusions - they are different engines with different designs and different builds.

No offence, but you didn't study engineering did you?
I have.
Edit: If a N20 rates at 275HP at the crankshaft, then a N55 could do 275:2(litres)=137.5 x 3(litres)= 412.5 HP.
That's a lot.
