Depends on what year it is
Not really They're fast enough :)
That depends what year it is the the average speed is 150 mph
The SE has a 24 valve 2.7L V6 that makes 178 horsepower, the SXT charger has a 3.5L V6 high out put 24 valve engine that produces 250 hp, they make an AWD SXT that has the same numbers as the normal...
The new ones are electronically limited to about 120, but are capable of a bit faster :)
