Dodge Challenger SRT Demon
The street-legal Dodge Challenger SRT Demon is outfitted with a modified version of the 6.2-liter supercharged and intercooled Hellcat engine that produces 840 hp, or 133 hp more than the standard 707-hp Hellcat Challenger.
The engine is mated to an eight-speed automatic transmission with a torque converter capable of sending the Demon's 770 pounds-feet of torque to the rear wheels.
