The Challengers are big cars. Whether that is an asset or not depends on your perspective.
I've actually had 2 grown adults in the back seat, comfortably for more than 20 minutes. Granted they're vegetarians, but still, I don't think that can happen in a GT or SS. Also, The trunk is positively cavernous. Which comes in handy when hauling groceries or the occasional dead hooker.
Some people like big. Khufu wasn't concerned with weight, and his project turned out OK.
For me, I can sleep soundly knowing Mopar now looks down from atop Mount Muscle Car Olympus.
