X5 engine history

[m j b]

**** I've got enough info now, no need to reply. Thanks! *****

You know, I had such an awesome response to my request for pictures that I'm going to mine this vast source of knowledge yet again. I'm doing a piece for the Roundel on the history of the X5, and I'm not having much luck getting any information from BMW NA. What I'm looking for is a timeline on the progression of engines offered in the American market for the E53. I'll post the same query in the E70 forum. And if there are any other noteworthy changes during the life of the E53, that would be good to know as well. I am shockingly, annoyingly ignorant about the X5 and all of its permutations.

Can you guys and gals help me out with this? I will be forever grateful and I'll try to throw in a plug for the forum as well.

Thanks!
Michael
