For the muscle car aficionados, Dodge recently released a few numbers that ought to fill in the informational cracks regarding the 2018 Challenger Demon. The company revealed the newest incarnation of the car in April, at the New York Auto Show, but had been tight-lipped on certain details regarding the stout vehicle.

Apparently, the 2018 Challenger Demon will be the recipient of an engine related less closely to the Hellcat. The Demon’s powerplant—a 6.2L V8 that can produce 808 horsepower, providing 717 foot-pounds of torque—got a virtual revision with, among other components, a new precision CNC-machined engine block unique to the model. Dodge tells us that the engine represents a 62% revision.

Also featured on the 2018: new pistons and rods engineered to better handle the substantial power produced by the engine, and a newly designed supercharger keeps up with the increased pressure from the fuel injector on the 2018 model; gas flow to the engine tops out at over one and one-third gallons per minute, and an improved cooling system sheds the heat produced by all that combustion. It’s not a terribly efficient car, but who buys a muscle car for efficiency? Burn, baby, burn.

Especially when that V8 Hemi can produce an additional 30 horsepower by setting the optional Direct Connection powertrain Controller, and using gasoline a little nearer to rocket fuel—100-octane gas brings the engine’s rating up to 840 horses. The torque provided at launch will supposedly produce nearly two G’s from a stop, and take the car to 60 in 2.1 seconds. Heavy, as the kids who drove GTOs used to say.
