I think the consensus is that it was an EPA/CAFE thing. The N54 is a less efficient/higher polluting engine than the N55, so there was no reason to call it a 2012 when calling it a 2011 would allow the car to be held to lower CAFE standards. (Any car produced up till December 31, 2011 can be labeled a MY 2011 for CAFE purposes.)
