Enthusiasts might love useful wagons, sporty coupes, open-air convertibles, and capable off-roaders, but sedans are still the go-to choice for buyers in the U.S. Make no mistake though, not all four-doors are doomed to grocery toting and commuting.

These top ten most powerful sedans you can buy here in the States can do it all, from laying down hot laps at the track to picking up the kids from school. Dive in and you'll see the ten most powerful four doors in their standard condition--that means no special tunings or performance packages that are added on at a premium.
