Word on the street is that when the 2018 Dodge Challenger SRT Demon is released it will be the most powerful, fastest, and quickest off the line production American muscle car of all time. And, the numbers this beautiful Dodge muscle car boasts sure suggest that this is true since its supercharged 6.2-liter HEMI Demon V8 engine pumps out 840 horsepower along with 770 lb-ft of torque. And, as the video above shows you, this dang production drag racing muscle car leaps off the ground when it launches from the drag racing strip starting line! Though final pricing figures have not yet been officially released, we do know that this beast of a muscle car comes with just a driver’s seat. You can get the optional passenger seat and rear seats for $1.
