SEALY, Texas (November 7, 2023) – Hennessey, the Texas-based hypercar manufacturer, and high-performance vehicle creator, celebrates the nine-year run of the supercharged 6.2-liter Hellcat HEMI V8 with limited edition ‘Last Stand’ models of the popular Dodge SRT Challenger and Charger models. 

Dodge’s admired supercharged 6.2-liter Hellcat HEMI V8 is offered in both its Challenger coupe and Charger sedan models in a variety of trims – Hellcat, Jailbreak, Redeye, and Super Stock – with outputs of up to 807 horsepower. Hennessey’s expert technicians, who have been ‘making fast cars faster’ for more than 32 years, fit the engine with a larger supercharger (non-Redeye models only), upgraded fuel injectors, a high-flow induction system, pulley upgrade, stainless-steel long tube headers, high-flow catalytic converters, and a crankcase ventilation system.

New engine calibration raises the output to an astonishing 1,000 horsepower and 948 lb-ft of torque. That’s only 25 horsepower shy of the automaker’s flagship SRT Demon 170 – and the Hennessey H1000 ‘Last Stand’ editions run on pump-unleaded gasoline. The Hennessey upgrades enable both models to sprint to 60 mph in just 2.8 seconds, while a quarter mile is dispensed in 9.9 seconds at 141 mph.

The Hennessey H1000 ‘Last Stand’ editions are differentiated by their lightweight carbon-fiber appointments – new rear spoiler, front splitter, side skirts, and rear diffuser. All boast distinctive 20-inch alloy wheels that can be optioned with either a gloss black or graphite-colored finish, special heritage ‘Last Stand’ graphics, and a plaque denoting the serial number for each of the 50 limited edition Challenger and Charger models.

“The Challenger and Charger are two of our most popular models, with monstrous horsepower in a comfortable and capable chassis. While it’s sad to see the 6.2-liter HEMI go, I’m pleased to commemorate its near-decade run with our unique ‘Last Stand’ models that pair the 1,000-horsepower output with the sleek look of carbon fiber and other exterior performance upfits.”

John Hennessey, company founder and CEO
