A 2023 Dodge Challenger SRT Demon 170 finished in Plum Crazy is being presented as a highly preserved example of Dodge’s most extreme factory-built muscle car. Designated as Demon 170 No. 2505 and carrying just 25 original miles, the vehicle remains in essentially as-delivered condition, complete with factory protective coverings still in place on the seats and interior trim.
The car represents the final evolution of the Challenger lineup and stands as the most powerful production muscle car built by the brand. At its core is a 6.2-liter supercharged D170 HEMI V8 engine featuring upgraded internal components, a larger 3.0-liter supercharger, a high-flow fuel system and flex-fuel capability. When operating on E85 fuel, the engine is rated at 1,025 horsepower and 945 lb-ft of torque.
Power is managed through a heavy-duty TorqueFlite 8HP90 eight-speed automatic transmission equipped with TransBrake 2.0, torque reserve and launch assist technology designed for consistent, forceful acceleration. A strengthened 240mm rear differential with a 3.09 gear ratio has been engineered to endure repeated drag-strip launches, reinforcing the car’s focus on straight-line performance.
The suspension system has been specifically calibrated to maximize traction and weight transfer. Adaptive Bilstein dampers, softer-rate springs and sway bars, and Demon-specific suspension geometry work together to optimize grip under hard acceleration. The vehicle rides on factory drag radials and features a raised rear ride height with revised camber settings to enhance contact with the pavement.
Combined with its widebody stance and drag-focused engineering, the Demon 170 delivers factory-rated quarter-mile performance comparable to dedicated race cars. Presented in near-delivery condition with exceptionally low mileage, this example underscores the closing chapter of Dodge’s modern muscle car legacy and is positioned as a significant collectible from the final run of high-horsepower Challengers.
