The facelift 3.0i (with detuned n52b30 engine) has 215hp.
That was probably introduced around beginning 2005. Facelifts have a different front&rear bumper and different rear lights, so easy to recognise. The 225hp engine (actually 228hp) is the m54b30 engine and was only fitted in the pre facelift models.

Does anyone know why they did this? I'd guess reliability or something along those lines, but I can't remember BMW every dropping power from an engine for a facelift. Usually they find and extra 10 or 15 hp somewhere in the higher end and make it rev a touch higher. Strange.

According to Realoem the facelifts already started production as early as october 2004, probably taken deliverance somewhere in 2005. That is probably a production run for 'introduction purposes'.
The bulk of the production started in april 2005. If models like that take deliverance after the summer (like in october or so) they are sometimes designated as '2006 model'. Quote:
Europe got the 2.5si (no 3.0i) with similar power, but probably in the US a lower cost (detuned) 3.0i (so a 3 litre engine) was more sellable.

Yep, I should've clarified this information is for US models only. I made sure the OP was American before I chimed in because Europe got different engines and I'm not familiar w/those. |

They did it to provide separation in the models. The 3.0si comes with more standard features. BMW forces the customer to buy the extra features to get the added power. You can swap intake manifolds and achieve 3.0si power on the 3.0i.
FWIW, the prefacelift 3.0i (M54B30) was arguably overbuilt with its forged crank and 10.2 static compression ratio. The 3.0si (N52B30) makes more power out of the box, but has less ultimate potential.

Mercedes does that too..
the 63amg's also arent 6,3liter anymore... But bmw already did this in the 90's on some models (the very low end ones, not sold in the US, but some got a lower designation than their capacity and it was a detuned base model). Oh wait a minute... that's the other way round
