Why This Car Is Special

The 2018 Dodge Challenger SRT Demon was not a limited edition in the marketing sense. It was a limited production car in the engineering sense — built for one model year only, with a specific mission: to be the fastest production car in the quarter mile ever certified by the NHRA at the time of its release. Dodge held nothing back. The Demon ran the quarter mile in 9.65 seconds at 140 mph on its factory Nitto NT05R Demon Drag Radial tires — numbers that, when announced in 2017, made headlines across every automotive publication on earth. The car was so fast that the NHRA required it to run with a roll cage or a parachute at sanctioned events above a certain speed. That's not marketing copy. That's a technical ruling from the governing body of drag racing in North America.

Dodge produced just 3,300 Demon units for the United States market for the 2018 model year. That number was set in advance and was not expanded. Each car came with a numbered certificate and a Demon Crate — a separate shipment containing the items removed from the car to reduce weight for drag racing, including the passenger seat, rear seats, and spare tire. The production figure was low enough and the demand high enough that many examples were marked up significantly over MSRP at the time of sale. Today, well-preserved examples like this one command serious collector money because the Demon was a single-year model that will never be made again.

This specific 2018 Dodge Challenger SRT Demon is finished in Go-Mango orange, one of the more visually assertive colors available on the Demon and one that connects directly to Dodge's muscle car heritage — the same name was used on factory Mopar cars in the early 1970s. The matte black hood provides contrast and serves a functional purpose, reducing glare for the driver and visually separating the performance-focused hood scoop area from the body color. This car wears the full Widebody package, which added 3.5 inches of total width to the Challenger's stance to accommodate the wider drag-focused track and tires.

Mechanical

The heart of the 2018 Dodge Challenger SRT Demon is the supercharged 6.2-liter HEMI V8, internally known as the Hellephant-adjacent "Demon" version of the supercharged 6.2. To be precise, this engine used a larger 2.7-liter supercharger than the Hellcat's 2.4-liter unit, along with revised fuel injectors, a higher-flow fuel pump, and revised engine management calibration. The result was 840 horsepower and 770 lb-ft of torque when running on 100-octane fuel. On 91-octane pump gas, the rating dropped to 808 hp — still the highest output of any production V8 in the world at the time of its launch, a record it held over the Hellcat, the Shelby GT500, and the Corvette Z06 of that era.

The Demon's supercharger swap alone would have been a significant upgrade over the Hellcat, but Dodge went further. The TransBrake feature — a function normally associated with purpose-built race cars — was included from the factory. It allowed the driver to build boost at the line while holding the car stationary, then release everything at once for an optimized launch. The 8-Speed TorqueFlite automatic transmission was tuned specifically for drag launches, and the car's torque converter was revised to transfer power more efficiently under hard acceleration.

This car has been fitted with a K&N cold air intake, which complements the factory Air Grabber Hood Intake system. The Air Grabber is a functional ram-air hood that opens automatically under wide-open throttle, drawing cooler, denser outside air directly into the supercharger inlet. This feature was a deliberate nod to the 1971 Dodge Demon and Plymouth 'Cuda's functional hood scoops of the classic muscle car era, and it works on the same basic principle — more air in means more power out.

The red Brembo brake calipers are factory equipment on the SRT Demon, paired with large vented rotors front and rear. Given the car's capability in a straight line, the braking system is not an afterthought. Brembo supplied high-performance compound brake pads as well, appropriate for the forces involved when bringing 4,200-plus pounds of car down from 140 mph.

Interior

The 2018 Dodge Challenger SRT Demon's interior is trimmed in black leather with the front bucket seats designed to hold the driver firmly in place under hard acceleration. The Demon, by design, deleted the rear seat and the front passenger seat from the car at the factory to reduce curb weight. Some owners opted to retain or reinstall those components — this listing should be confirmed with our sales team regarding current seat configuration.

The center console houses the transmission controls and provides the driver-focused layout that SRT intended. Power windows and power door locks are standard, keeping the car usable as a daily driver despite its track-oriented engineering. The Demon's instrument cluster included a dedicated Performance Pages display, which gave the driver access to real-time data including 0-60 times, quarter mile results, g-forces, and torque output — all factory-integrated tools for a car that was designed to go to the drag strip and come back home the same afternoon.

SRT badging appears throughout the cabin, reinforcing that this is not a base or mid-level trim. The Demon was always the top of the SRT hierarchy, positioned above the Hellcat and the Hellcat Widebody in the Challenger lineup.

Exterior

Go-Mango orange is one of the standout color choices from the 2018 Dodge Challenger SRT Demon's option sheet, and it suits the widebody silhouette well. The extra width added by the factory Widebody fender flares gives the car a proportionally wider, lower visual stance, and the contrast of the matte black hood against the bright orange body is a factory-engineered design decision, not an aftermarket modification.

The Demon Front Splitter is a functional aerodynamic component designed to reduce front-end lift at speed, which becomes relevant quickly when a car runs 140 mph in the quarter mile. It sits low to the ground and is a known wear item on cars that are driven regularly — the condition of this splitter should be noted by prospective buyers during inspection.

The Nitto NT05R Demon Drag Radial tires are a critical piece of the Demon's performance equation. These are not summer performance tires or high-performance all-season tires. They are drag radials — a category of tire that provides significantly more mechanical grip off the line than a standard street tire, which is a large part of why the car ran the quarter mile numbers it did. They are approved for street use but optimized for the drag strip. The black Widebody fenders clear these tires cleanly and give the car the visual stance to match the mechanical purpose.

The red mirror caps, visible in the photos, and the SRT badging on the exterior confirm the build specification and trim level at a glance to anyone familiar with the Challenger lineup.

Conclusion

The 2018 Dodge Challenger SRT Demon is the kind of car that gets discussed in automotive history books because it did something no production car had done before it — cleared a sub-10-second quarter mile from the factory, with a warranty, on street tires, driven by anyone who bought a ticket at the drag strip. Dodge built 3,300 of them for the United States, sold them for one year, and moved on. There is no follow-up Demon of the same generation. The Hellcat carried on, the Redeye came later, and eventually the SRT nameplate on the Challenger came to an end with the last of the HEMI-powered cars in 2023. But the Demon occupies a specific place in that history that nothing else in the lineup touches.

This example, in Go-Mango orange with the full Widebody package, the Air Grabber intake, Brembo brakes, Demon Drag Radials, and the supercharged 6.2L HEMI producing 840 horsepower, is the real article — not a replica, not a clone, and not a base car with cosmetic upgrades. If you are looking for a documented, collectible performance car from the modern era with genuine drag racing capability and a production story that will not be repeated, the 2018 Dodge Challenger SRT Demon is worth a serious look.
