When Dodge pulled the sheets on the utterly insane Challenger SRT Demon back in April at the 2017 New York International Auto Show, months of speculation finally collided with reality, and the result was one of the most badass factory drag racers ever unleashed. The headline specs on the Demon beg belief, with nearly 850 horsepower and 770 pound-feet of torque sent to the rear axle thanks to a supercharged 6.2-liter V-8. Stuffing the engine is a 2.7-liter supercharger producing 14.5 psi of boost, which prompts at 2.3-second sprint in the 60-mph benchmark. Keep your foot down, and you’ll see the quarter mile blitzed in 9.65 seconds at 140 mph. Insanity. Now, Dodge has a full rundown on hard numbers to document that craziness with the release of the Demon’s powertrain spec sheet.
