The Hennessey Mammoth 1000 TRX is this. ‘Mammoth’ is used because, well, it’s a gigantic, hairy beast; ‘1000’ is used because it has 1000 horsepower and nearly 1000 pound-feet of torque; and ‘TRX’ because it is built on Dodge’s fastest Ram TRX 1500 pickup with a Hellcat engine.
The most recent monster to leave Hennessey’s facilities is the Mammoth 1000. With 1012 horsepower and 969 pound-feet of torque, this 3-ton truck has outputs that can compete with a Bugatti Veyron. These figures support Hennessey’s claim that it has created the world’s most potent and swiftest-accelerating pickup.
Mammoth also means powerful, exactly as how truly powerful DRX was. Here’s another justification why DRX is a better moniker for the Hennessey Mammoth 1000. The only pickup in the entire world that can finish the quarter-mile run in 11.4 seconds is this one. At a speed of almost 120 mph, it did that vrooming. A 6.2L supercharged Hellcat V8 engine with 1,012 horsepower replaces the RAM 1500’s powertrain in the truck.
It goes without saying that Americans adore pickup trucks. The 2024 Dodge Hornet R/T boasts a powerful plug-in hybrid trim that combines an electric motor with a smaller engine. As the name implies, Ford’s 450 horsepower F150 Raptor is like a Scooby Snack to Dodge’s 702 horsepower, standard Hemi-powered TRX.
The 700-horsepower Raptor R could change that, but Hennessey seems to have it covered. The Mammoth’s 0-60 mph time decreases by half compared to normal TRX’s, resulting in a 3.7 second time and a standing quarter mile time of 11.4 seconds. The top speed has been increased from the standard model’s 118mph to 130mph.


John Hennessey, CEO of Hennessey Performance Engineering, has unveiled a larger version of their flagship product, the Mammoth 1000 6×6. It is also still incredibly quick while being an absolute force off-road. It is without a doubt the road’s monarch.
The incredibly potent Hennessey Mammoth 1000 is best described as the uncontested king of the road. The limited edition TRX was initially mentioned by HPE in 2020, and production began the following year. Given that HPE intended to build the monster based on the Dodge RAM TRX, we practically heard the Ford Raptor, Roush Ford F150 Nitemare, or even the Hennessey Ford F150 Venom 775 and Hennessey Jeep Gladiator Maximus let out a collective sigh of dread.
The Hennessey Mammoth 1000 is a pickup truck that significantly enhances its capabilities both on and off-road, based on the 2021 Ram 1500 TRX.
Since the RAM 1500’s terrifyingly potent 6.2L Hemi V8 Hellcat engine could crank out 702 horsepower and 650 pound-force feet of torque, enabling it to tow and haul like no one’s business, it made fitting that Chrysler called the truck after the Tyrannosaurus Rex (TRX). That’s impressive, just like how impressive T-Rex was as a creature. However, the Mammoth 1000 is bigger and better than the Indominus Rex, to use John Hennessey’s phrase.
The undisputed ruler of the road is a monstrous 228.9 inches long, 82.1 inches wide, and 77.6 inches tall, giving him a frightening presence.

Performance, Engine, and Others

Thus, the Mammoth 1000 is essentially a TRX RAM that focuses on performance.

An 8-speed automatic transmission is mated to the engine to provide constant 4-wheel-drive power. The TRX truck boasts a faster acceleration time of 3.2 seconds, surpassing its predecessor’s 4.5 seconds in Sports Mode. With 969 pound-force feet of torque, the Hennessey Mammoth 1000 is not only quicker than its mother but also the quickest pickup truck ever built.
The Hennessey Mammoth, equipped with a high-flow 2.6L supercharger, fuel injectors, and induction system, effectively turns competitors into prey through performance-enhancing tuning.

Hennessey Mammoth 1000: Interior

This is “the most potent pickup truck that Hennessey Performance has ever offered,” to paraphrase John once more. The Ram TRX, a powerful new truck, boasts the highest horsepower of any pickup by a car manufacturer. Over 100 trucks have been sold, each highlighting the advantages of owning a pickup truck with 1,000 horsepower. Since we can!”
Sure, “Mammoth” gives off an optimistic, “yes, we can” vibe. The spacious interior, accommodating six comfortably and carrying over 1,310 lbs, demonstrates significant confidence. The Indominus Rex, a powerful vehicle, boasts a maximum trailer weight of 5,000 lbs and an impressive towing capacity of 8,100 lbs.
HPE’s vehicle boasts a 2.5-inch lift kit, 20-inch ten-spoke wheels, 35-inch off-road tires, retractable electronic bed cover, LED lighting, and front suspension leveling system.
Hennessey has not confirmed any interior changes for the tuning house, but customers can expect its distinctive badging to make it stand out. The RAM 1500 TRX, a powerful and exciting system, is a must-have for those seeking remarkable performance in their TRX. The MAMMOTH 1000 modifications have transformed this pickup into a unique, powerful, visually stunning, and captivating object.

Hennessey Mammoth 1000: Price

If you want to purchase one of the 200 Hennessey Mammoth 1000s planned for manufacturing, you need to budget $375,000. The business advised that most owners should start with a highly specified stock vehicle and then add the Stage 1 and Stage 2 packages of the Hennessey performance package.

The Stage 2 package includes custom bumpers, LED lighting, a front leveling kit, 37-inch off-road tires, and enhanced electronic fold-out steps. All are covered by a 2-year (or 24,000-mile) warranty. If you go this route, the Hennessey Mammoth 1000 turnkey pricing will cost you $135,350.


The Mammoth is a ridiculous machine in every way, but it’s also an enormously fun counterbalance to the relatively stuffy European and British fast car scene. This is the biggest driving thrill there is.
