So the September factory changeover is not necessarily a factor in what BMW NA calls the car and what the VIN reads. Just as important to note is the fact that BMW often makes major changes during the February/March timeframe as well.

More and more, it seems most likely to me that all X1 28i built from March on will have the T4 rather than the N52 I6. In other words, I don't think they'll overlap T4 and I6 production. And in turn, my feeling is that any X1 with a turbo 4 in it will be called a MY2012 in North America.

Exactly!
