The Dodge Challenger SRT Demon is a limited-production, high-performance muscle car produced by the American manufacturer Dodge. Introduced in 2017 for the 2018 model year, it was developed as an extreme, drag-focused variant of the Dodge Challenger lineup. The SRT Demon was engineered to deliver maximum straight-line acceleration and track performance.

The vehicle is powered by a supercharged 6.2-liter HEMI V8 engine, specially tuned to produce higher output than the standard Hellcat variant. It features numerous performance modifications, including reinforced drivetrain components, upgraded suspension, lightweight body elements, and specialized drag radial tires. The Demon was also notable for offering factory-supported drag racing equipment and configurations.

Produced in limited numbers, the Dodge Challenger SRT Demon set records for production-car acceleration at the time of its release. It represents a highly specialized interpretation of the modern American muscle car, emphasizing extreme power and drag-strip capability.
