Ultimately, that piece is from "autoblog" and they do not cite any particular documents, or source, by name, within Dodge, nor any sort of pre relase design work on such an animal. In court they would call that hear-say and make it inadmissable.
I still think of it as a ratings type of hype that writers will delve in to from time to time and will believe it with some pre-release photos or pre produciton testing documentation.
