To do this, it combines the best of both mechanical and electronic tuning to deliver maximum launch grip while still maintaining precision directional control.

The Bilstein Adaptive Damping shocks have been tuned for drag racing, shifting as much weight as possible on the rear tires at launch for maximum traction. The weight transfer improves rear tire grip by 11 percent.

Mechanically, weight shift in the Challenger SRT Demon is aided by softening up some key suspension components. Those changes, compared with the Challenger SRT Hellcat, include:
  • Softer springs: 35 percent lower rate front/28 percent lower rate rear
  • Softer, lighter, hollow sway bars: 75 percent lower rate front/44 percent lower rate rear
When Drag Mode is activated, the front Bilstein shocks are set for firm compression and soft rebound damping, while the rear Bilstein shocks are set for firm compression and firm rebound damping.

That configuration is maintained as long as the car runs at wide open throttle. When the driver backs off the gas pedal, the system switches to firm compression and firm rebound front and rear for improved handling.

Also during Drag Mode, the traction control system is disabled to enable the rear wheels to spin for a burnout, but the electronic stability control system remains engaged to help the driver with straight-line performance.

In pursuit for every tenth of a second, engineers looked to cut as much weight as possible. The result: Equipment removed from the Challenger SRT Demon weighs more than 200 pounds.

How the weight was lost:
  • 58 pounds: Removed front passenger seat and belt
  • 55 pounds: Removed rear seat, restraints and floor mats
  • 24 pounds: Removed 16 audio speakers, amplifier and associated wiring
  • 20 pounds: Removed trunk deck cover trim, carpeting, spare tire cover
  • 19 pounds: Used smaller, hollow sway bars
  • 18 pounds: Removed mastic, body deadeners, insulators and foam
  • 16 pounds: Used lightweight all-aluminum four-piston brake caliper and smaller, 360-mm two-piece rotor
  • 16 pounds: Switched to lightweight wheels and open-end lug nuts
  • 4 pounds: Switched to manual tilt/telescope steering column
  • 2 pounds: Removed park sensors and module
Buyers have the option to add back the front passenger seat, rear seats and trunk carpeting kit for $1 each. Other options include the Harman Kardon 19-speaker, 900-watt audio system, power sunroof, heated and ventilated leather front seats with heated steering wheel, painted Satin Black hood, or new painted Satin Black hood, roof and decklid package.

The 2018 Dodge Challenger SRT Demon gives the driver the capability to set up the car for on-road precision, maximum drag strip performance or anything in between.

The nerve center for those personalities is SRT Performance Pages and Drive Modes, displayed on the Uconnect 8.4-inch touchscreen.

Performance Pages arm the driver with real-time data, including a graphic display of engine horsepower and torque with gear changes plotted; supercharger coolant temperature; timers for reaction time, 0-60 miles per hour (mph), 0-100 mph, eighth-mile and quarter-mile elapsed time and vehicle speed; instantaneous and peak longitudinal and lateral g-forces; and gauge readouts for engine oil temperature and pressure, coolant temperature, transmission fluid temperature, intake air temperature, air-fuel ratio; intercooler coolant temperature, boost pressure and battery voltage.

The Drive Modes include the Challenger SRT Demon-exclusive Drag Mode. Drive Mode settings include Auto (Street) Mode, which sets the Bilstein Adaptive Damping Suspension (ADS) for comfortable ride with compliant handling, and Custom Mode, which lets the driver select between Auto and Drag Mode configurations for the transmission, paddle shifters, traction, suspension and steering.

Auto (Street) Mode options:
  • Engine output level is set based on which Demon key is in the vehicle
  • If red key is present, the power level can be set per customer preference
  • Transmission, suspension and steering default to Auto Mode (Street)
  • Customers can set suspension and steering preference
  • Electronic Stability Control defaults to full on
  • Paddle shifters can be turned on or off per customer preference
  • Eco mode is available only in Auto Mode
Drag Mode options:
  • TorqueFlite eight-speed transmission runs a calibration optimized for acceleration
  • Electronic Stability Control is optimized for straight-line acceleration
  • Suspension calibration changes to full firm in rear and firm compression/soft rebound in front
  • Paddle shifters are turned on
  • Steering is set to Drag Mode for high-speed stability
  • Cabin cooling diverted to SRT Power Chiller
  • Torque converter lockup point is raised in Drag Mode
  • TransBrake is available in Drag Mode only
Custom Mode options:
  • Nearly every combination of options available in Auto (Street) or Drag can be configured in the Custom Mode. For example, a driver could select the elements of Drag Mode related to engine and transmission performance, but could select Sport Mode for the suspension and steering, providing the on-road driving dynamics of a Challenger SRT Hellcat
When equipped with the Direction Connection Performance Parts powertrain control module, the driver can use 100+ high-octane unleaded fuel in any drive mode.

Drivers can also select line lock, which engages the front brakes to hold the Challenger SRT Demon stationary but leaves the rear wheels free for a burnout to heat up and clean the rear tires. The system will also let the driver perform a controlled rolling burnout. The system engages for up to 400 rear wheel revolutions.

Performance Pages also includes rpm-adjustable launch control and by-individual-gear-adjustable shift light displayed in the instrument cluster. A new data recorder feature lets the Challenger SRT Demon driver build an archive of data to help optimize the car for track and weather conditions, while helping to improve driving techniques.

Eco and Valet Modes are accessed in the Performance Pages. When Valet Mode is activated, engine horsepower is reduced and rpm is limited to 4,000. Also, certain performance features, such as steering wheel paddle shifters and Launch Control, are disabled. The driver can activate and de-activate Valet Mode with a four-digit PIN code they create.

The 2018 Dodge Challenger SRT Demon is the widest Challenger ever and first-ever, factory-production muscle car with wide-body fender flares.

The wide body flares are designed to amplify the Challenger SRT Demon's menacing stance, while making room for wider tires with concealed attachments. The fender flares, which cover the lightweight 18x11-inch wheels with exclusive, specifically designed Demon-branded 315/40R18 Nitto NT05R drag radial tires front and rear; add 3.5 inches to the Challenger SRT Demon's overall width. The front side marker lights are styled to flow with the shape of the fender flares.

The entire chassis is e-coated for durability before final assembly.

Additional defining exterior features include the wide Air-Grabber hood scoop - the largest functional hood scoop (45.2 square inches) of any production car - and new Demon logos flanking each fender.

The driver is the focus in the interior of the Challenger SRT Demon, as it is for every model in the Challenger lineup.

Both the front passenger seat and rear seat, along with their corresponding seat belts, are deleted in the standard configuration of the Challenger SRT Demon.

Customers have the option of adding seats into the car, as well as adding leather coverings, when it is ordered. The front seat (s) have the Demon head logo stitched or embossed into the seat back.

Seating configurations:
  • Driver seat only, premium cloth covered
  • Driver and front passenger seat, premium cloth covered
  • Driver and front passenger seat, Laguna leather and Alcantara suede covered
  • Driver, front passenger and rear seats, Laguna leather and Alcantara suede covered
Facing the driver is a flat-bottom SRT Performance steering wheel wrapped in Alcantara with paddle shifters. The SRT white-face gauges include a 200-mph speedometer and flank the 7-inch thin-film transistor (TFT) cluster display screen. A custom carbon fiber instrument panel badge with "Demon" script is located on the outboard vent and signifies the build sequence number.

A new four-point harness bar, available through Speedlogix, is available for use at the track. Mounting points for the bar are accessible, making it easy for customers to install without cutting or drilling anything.

Standard cloth seats include Ballistic II inserts with silver embroidered Demon head logo in the seat backs. An optional Laguna Leather Package includes leather covered seats and trim with embossed Demon head logo.
