Hennessey’s H1000 package transforms the Dodge Hellcat into a 1,000-hp, 948 lb-ft muscle car monster built for speed and dominance.
The Dodge Challenger Hellcat is already a titan in the muscle car world—but Hennessey Performance Engineering has just raised the stakes. Introducing the H1000, a comprehensive performance upgrade that pumps the Hellcat’s output to a jaw-dropping 1,000 horsepower and 948 lb-ft of torque, redefining what’s possible from America’s iconic supercharged coupe.
Built specifically for non-Redeye Challenger Hellcats, the H1000 package brings together an arsenal of high-performance components, including a high-capacity supercharger, upgraded fuel injectors, a redesigned air induction system, and a custom-tuned ECU calibrated for maximum output and reliability.
These enhancements don’t just increase power—they sharpen throttle response, improve boost efficiency, and enhance overall drivability, making the H1000 as responsive in a straight line as it is on winding roads or drag strips.
Hennessey’s signature blend of engineering precision and track-tested performance ensures that each H1000 build maintains factory-level refinement with extreme, race-grade capabilities. Every H1000 car includes a limited warranty, providing rare peace of mind in the world of high-horsepower upgrades.
Externally, the H1000 doesn’t stray far from the classic Hellcat design but adds a deeper, more aggressive exhaust tone and subtle tweaks that hint at the beast within. The result is a muscle car that commands attention even before it hits the gas—and pure intimidation once it does.
With the H1000 Challenger, Hennessey reaffirms its status at the forefront of American performance tuning. It’s not just an upgrade—it’s a statement, and a ferocious one at that.
