Dodge has officially unveiled all the details on the 2018 Challenger Demon drag car. The car has 840 hp and 770 lb-ft of torque from its supercharged 6.2L HEMI V8 engine. 
Dodge says this is the highest horsepower V8 production car engine ever made. Dodge also says that this is the first production car ever able to lift its front tires 2.92-feet into the air at launch and is certified by the Guinness World Records folks.


Compared to the Hellcat’s engine, the Demon uses a 2.7-litre supercharger rather than 2.4-litre one, has a higher rev limit of 6500 rpm, has two dual-stage fuel pumps instead of one, has increased boost pressure (up from 11.6psi to 14.5psi), and is capable of running on both 91- and 100-octane fuel.

The car can run the quarter mile in 9.65 seconds at 140 mph stock and is certified by the NHRA. The Demon’s engine also has a larger induction air box sucking in air from the Air-Grabber bonnet scoop, the Air-Catcher headlight on the driver’s side, and an unnamed inlet near the wheel liner.


There’s also the Power Chiller, which diverts air-conditioning refrigerant to a chiller unit for coolant heading to the supercharger’s heat exchangers. The After-Run Chiller keeps the coolant pump and engine cooling fan running even after the car has been turned off, and can inform the driver of when the supercharger is back to its optimum temperature.

Drive is delivered to the rear wheels via an upgraded eight-speed automatic transmission. The new TransBrake system aims to aid the driver with standing starts by locking the transmission shaft, allowing the engine to hit 2350 rpm without overwhelming the brakes.


The car can run on 100+ octane race fuel or normal fuel. It also has a production car first TransBrake for launches. The car can run 0-60 mph in 2.3 seconds and has a 1.8g acceleration force. It’s hard to believe that sort of performance can come from a car with a factory 3/36k bumper to bumper warranty and a 5/60k powertrain warranty.

The Demon rides on Bilstein Adaptive Damping shocks and 18-inch wheels with 315/40 Nitto NT05R street-legal drag racing tyres. The suspension setup include softer springs, and lighter, hollow sway bays.


Dodge has stripped over 90 kg from the Hellcat to create the Demon. Items junked include the front passenger’s seat, rear seats, audio system, boot trim, parking sensors, and electronic steering adjustment.

Buyers can opt to reinstate the front passenger’s seat, rear seats, and boot carpets for a dollar each. Other options include a 900W 19-speaker Harmon Kardon sound system, sunroof, heated and ventilated leather front seats, and a satin black bonnet, roof and boot lid.


All of these upgrades are good enough to send the coupe from 0-60 mph in 2.3 seconds, which Dodge claims makes it the world’s fastest production by that metric.

Demon owners have three driving modes — Street, Drag and Custom — to select from, and these settings can alter the amount of power and torque available, transmission calibration, suspension tune, paddle shifter usage, stability control setup, and the availability of certain features, including the Power Chiller and TransBrake.


The Uconnect infotainment system can also be setup to display pages of performance and vehicle information, including power and torque graphs, instantaneous and peak g-force figures, various temperature and pressure gauges, current boost pressure, and 0-60 mph, 0-100 mph, quarter mile and vehicle timings.

The Demon will be produced only for the 2018 model year, with output limited to 3000 cars for the USA, and 300 for Canada. Deliveries of the Challenger SRT Demon begin in the third quarter of 2017.
