The whole "police interceptor" package was bs anyway. Stiffer springs for carrying more weight, re-enforced floorpans, keyed alike doors and ignition, and no engine upgrades for the crown vic or the mustang, as both came stock with dual exhaust. It just made the cops feel extra cool
(a small number of the crown vics did come with a hand brake as opposed to the pedal park brake)
The charger's a little faster than the rest, but not by much.
The cops also feel cooler peelin out after you in a rwd car
Bottom line, you're either gonna stop or you're not, no matter what's chasing you.
