The Dodge Challenger 392 Scat Pack Shaker screams American muscle like no other car on the road. This beauty is sure to put a stupid grin on your face as you row through the gears listening to the pristine exhaust note of the 6.4 liter Hemi V8 engine that makes 485 horsepower and 475 pound feet of torque. That's enough to throw you back in your seat with even the slightest pressure on the gas pedal. The beast can certainly be tamed though, when it's not in sport mode the car behaves itself very well. The newly redesigned interior makes for quite the comfortable cabin for even the longest of road trips.
