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.

John Hennessey, company founder and CEO: "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."

The H1000 'Last Stand' upgrade is available on 2021-2023 Dodge SRT Challenger and Charger models. All upgrades are backed by Hennessey's comprehensive 3-year / 36,000-mile warranty. Already in build at Hennessey's Sealy, Texas manufacturing facility, the Last Stand is available for global shipping.
