Dodge Challenger SRT Demon
If, for any reason, 707 HP from the Hellcat package is not enough for you and you want the ultimate modern muscle car and the most potent street Hemi engine ever made, then the Demon package is just the thing. Standard fuel will deliver an insane 8an 08 HP, but using high thigh-octane will pump out almost 840 HP. The rest of the Demon package is equally insane, from special transmission, suspension, and brake to widebody stance and exterior details.
