Hennessey Pays Tribute to Hellcat Legacy with 1,000-hp Challenger and Charger Special Editions

Hennessey Hellcat 1000-hp upgrade

As the curtain begins to close on Dodge’s reign of the Challenger and Charger SRT Hellcat, which dramatically altered the landscape of attainable muscle car performance upon their arrival nearly ten years ago, their production is drawing to a finale.

The terminus of the 2023 model year will mark the cessation of production for these high-powered icons, as the parent entity Stellantis has announced it will halt the manufacturing of their formidable supercharged 6.2-liter V-8 engines when the year concludes.

For a number of years, Hennessey has been engineering 1,000-hp incarnations of these vehicles, and to commemorate the conclusion of this era, the Texas-based high-performance manufacturer is unveiling a terminal-edition upgrade, dubbed the H1000 Last Stand package.

This final salute is applicable to the 2021-2023 models of the Challenger and Charger SRT Hellcat, with production constricted to a mere 50 units. This powerhouse upgrade harnesses a robust 1,000 hp, narrowly trailing by just 25 hp behind the formidable Challenger SRT Demon 170’s prowess. Notably, the Hennessey variants attain this monumental power utilizing standard pump gasoline, in contrast to the Demon 170 which necessitates E85 fuel to reach its peak performance—otherwise, its output declines to 900 hp.

The performance metrics quoted for the Hennessey modifications are remarkable, promising a sprint from 0 to 60 mph in a swift 2.8 seconds, and completing a quarter-mile dash in just 9.9 seconds, clocking in at a speed of 141 mph.

The principal enhancements constituting this package include an upsized supercharger (exclusively for non-Redeye editions), an enhanced pulley system, a freshly designed throttle body, extensive headers, catalysts engineered for optimal flow, superior fuel injectors, and an advanced intake system. Each component is meticulously calibrated on a chassis dynamometer to ensure symbiotic operation, supplemented by rigorous testing on both road and track. Hennessey guarantees the reliability of these modifications with a three-year, 36,000-mile warranty.

The aesthetic differentiation of these vehicles is achieved through exclusive carbon fiber elements such as a bespoke rear spoiler, diffuser, front splitter, and side skirts. Complementing these features is a unique Last Stand graphics suite, along with distinct 20-inch rims available in either gloss black or gray finishes. A serialized commemorative plaque denotes each unit’s unique sequence within the limited production run.

The starting price for this exclusive enhancement is pegged at $64,950. For those presenting a Redeye model as the base vehicle, the package price is reduced to $54,950 due to the supercharger already meeting the requisite specifications.

In a parallel gesture, Hennessey is also orchestrating a 1,000-hp farewell tribute for the Chevrolet Camaro, which is set to make its exit after the 2024 model year.

While Chevrolet has yet to unveil plans for the Camaro’s successor, Dodge has already taken steps towards an electrified future, having showcased a prospective heir with the Charger Daytona SRT concept last year.
