I found this article interesting. It does not add much that isn't on this forum except that it does discuss the good
touring feel of the
non-SRT Xfire. After two years of owning both a roadster(6 speed) and a coupe (automatic) I found the discussion of the 2000 to 3000 rpm feel to be critical to the sweet spot for the Xfires I own.
