Thanks south. I guess that second-to-last pic showing "xDrive50i" removes all doubt (if there were any left) as to whether the 4.4L N63 will replace the 4.8L N62.
And with that the N62 can officially be put into the history books, at least as far as OEM BMW vehicles are concerned. Edit: I take that back. One more year in the 650i. Then its done.
