This 2023 Dodge Challenger SRT Demon 170 is a 31-mile example that was delivered new to DropTop Customs of High Springs, Florida, where a convertible conversion was carried out. Power is provided by a supercharged 6.2-liter Hemi High-Output V8 producing up to 1,025 horsepower and 945 lb-ft of torque, which is sent to the rear wheels via a TorqueFlite eight-speed automatic transmission and a limited-slip differential. Finished in TorRed (PR3) over Black Alcantara and Laguna leather, the car is equipped with Air-Catcher HID headlights, an Air-Grabber hood, a front splitter, an SRT Performance rear spoiler, flared quarter panels, a “Last Call” underhood plaque, a rear parachute, four-piston Brembo brake calipers, 18″ front and 17″ rear forged aluminum wheels, heated and ventilated front seats, a heated steering wheel, dual-zone climate control, a trunk dress-up kit, a Harman Kardon sound system, and UConnect infotainment with navigation. Acquired by the selling dealer in 2023, this SRT Demon 170 convertible is now offered with a Droptop Customs owner’s manual, three keys, and a Florida title.
Dodge released seven different Last Call special editions for the 2023 model year to celebrate the end of production of the Charger and Challenger, and the Demon 170 was the final special edition variant. This example is finished in TorRed (PR3) and it was fitted with a power-operated black soft top as part of the convertible conversion. Exterior details include an Air-Grabber hood with a satin black graphic and “Alcohol Injected” lettering on the hood-scoop bezel. Other exterior details include a front splitter, Air-Catcher HID headlights, flared rear quarter panels, a rear parachute, dual exhaust outlets, and an SRT Performance rear spoiler with an integrated rearview camera.
The car rides on black-finished 18″ front and 17″ rear forged aluminum wheels, and stopping power is provided by black four-piston Brembo calipers with yellow SRT lettering over ventilated discs. The Demon 170 is equipped with an edition-specific Drag Mode suspension with adaptive-damping shocks as well as launch control, a line lock, and a revised transbrake.
The heated and ventilated front seats and the rear bench are upholstered in Black Alcantara and Laguna leather. A trunk dress-up kit was optioned from the factory, and carbon-fiber trim accents the dashboard and center console. Other amenities include remote start, dual-zone climate control, a Harman Kardon sound system, and UConnect infotainment with navigation and Android Auto and Apple CarPlay capability. Demon 170 models left the factory with a reduced amount of sound-deadening materials compared to the standard Challenger.
A plaque below the passenger air vent identifies this Demon 170 as #2891.
Shift paddles are affixed to the rear of the heated Alcantara-wrapped multifunction steering wheel, which frames a red 220-mph speedometer, a 7k-rpm tachometer, and a 7″ configurable digital display. The digital odometer indicates 31 miles.
The 6.2-liter Hemi High-Output V8 is equipped with a 3.0-liter supercharger with a 3.02″ pulley and a 105mm throttle body in addition to revised fueling system components, Nitride-coated intake valves, copper-lead bearings, and upgraded cylinder head studs when compared to the previous Demon model. The horsepower rating adjusts automatically based on the ethanol percentage in the fuel, and output ranges from 900 horsepower and 810 lb-ft of torque with conventional E10 fuel to 1,025 horsepower and 945 lb-ft of torque when using E85. The engine is also equipped with an SRT Power Chiller, which utilizes the air conditioning refrigerant to cool the air entering the intake ports. The battery and spark plugs were replaced in February 2026.
Power is routed to the rear wheels via a TorqueFlite eight-speed automatic transmission and a 3.09:1 limited-slip differential with a strengthened housing and a 240mm ring gear. The Demon 170 also features an improved rear prop shaft and 43-spline rear half shafts.
