how old are you again? Think in ways of budget, say a township or city counsel has the option to purchase two 25k$ charger's or 2 22k$ crown vics for their officer's. One of which is a new product and has yet to be proven in the line of duty the other has been used for years, proven, reliable and cheap to repair/rebuild/replace. Not only that but with the money 6k they save on NOT purchasing the "cool" new charger they could then invest it into safety equipment for their officers, OverTime pay, possibly start another salary for a PT officer or invest it into other areas that are equally important to the maintenance of a small township/city.
And should the rumor prove to be true that Ford is actually trying to put the 3v into newer Crown Vic's, even if their HP number's are lower they will still have a superior product.
NOTE: These monetary figures are strictly for example purpose's and are not exact figures as far as i know.
