but some times cruise control will save you gas so it may give you a boost over what the EPA says..... As for targeting panthers it is probally because after the caprice was ended and there is not many of them so really crown vics were the only replacement that was avalible with a V8 and a four door but with out the panthers the cops would be sitting ducks with their V6 taurus or V6 impalas or malibus look at what they were used as and how many were made they have panthers as cop cars, Taxis, every day daily drives, executive cars or hearses but if ford desides to keep the panther it needs some major redesigning since the crown vics had have the same look since 1998.
