Hennessey is known for making some pretty insane rides, including augmentations to popular American machines, such as the Ford Mustang, Chevrolet Camaro and Corvette, and, of course, the Dodge Challenger and Charger.

As you may already know, Dodge is officially ending the Challenger and Charger after the 2023 model year. Now, Mopar has gone ahead and given their own special send-off to these modern muscle machines a la unique “Last Call” appointments and special edition trims, like the Challenger ‘Black Ghost’ we tested earlier this year. But in their own unique twist, Hennessey has upped the ante.

The Texas-based performance house has debuted the Hennessey H1000 ‘Last Stand’ Challenger and Charger. You can probably guess– they’ve managed to soup up the supercharged 6.2-liter HEMI V8 to a staggering 1,000 horsepower. Along with 948 lb-ft of torque, these ‘Last Stand’ models are anticipated to run 0-60 mph sprints in about 2.8 seconds, completing the quarter mile in 9.9 seconds at 141 mph. And that’s on unleaded pump gas.

Hennessey Honors Dodge Challenger and Charger with their own “Last Call” Twist 1

This is a big jump from the 6.2’s max output of 807 horsepower, and comes pretty close to Dodge’s SRT Demon 170, dispensing up to 1,025 HP from its built-up 6.2-liter. Here in the Hennessey, the engine has been outfitted with a larger supercharger on non-Redeye models, upgraded fuel injectors, a high-flow induction system, a pulley upgrade, stainless steel long tube headers, high-flow catalytic converters, and a crankcase ventilation system. Performance gains are also made possible by new engine calibrations.

We say “non-Redeye models” because this is an upgrade kit made available for all 2021-23 Dodge SRT Challenger and Charger models. Once built, it’s backed by a 3-year/36,000 miles warranty.

Not just an engine overhaul, the ‘Last Stands’ are modified with their own unique aesthetics. Carbon fiber is used extensively, comprising the rear spoiler, front splitter, side skirts and rear diffuser. The 20-inch wheels are new, finished in either gloss black or graphite, and are joined by heritage-themed ‘Last Stand’ graphics and a unique serial plaque.

Speaking of, this run is limited to just 50 units, so prospective buyers will want to place their orders soon.
