Crown Victorias aren\'t meant to be quick. They are meant to be durable and strong. Where I\'m from is irrelevant. Assuming you aren\'t from the USA, you wouldn\'t know that most police forces have cars designated for high speed pursuit other than the crown vic. You also wouldn\'t know that it\'s a police officer\'s job to stay within a safe distance of a high speed assailant and have a chopper follow overhead. One lunatic at 150+mph is more than enough. Police officers depend on their radio and road blocks to stop high speed chases. Actually, some states and counties have no chase policies entirely, to avoid possible innocent casualties.
Let\'s compare two similar cars from the same year. The 1994 Cadillac and 1994 E50 sedan.
As you can see, both cars have a V8 but the Cadillac weighs less despite the fact that it\'s significantly larger.
Make no mistake, I\'d sooner own the E50 over the POS SLS, but it shows that American doesn\'t necessarily mean heavier.
