Hennessey starts build of its biggest and most exclusive six-wheel-drive truck
6.2-liter supercharged Hellcat V8 | 1,012 bhp | 969 lb-ft torque | 283-inches (719 cm) long

  • Mammoth 6x6 is biggest truck ever created in Hennessey's 30-year history
  • Just 12 Hennessey Mammoth 1000 6x6 TRX trucks will be built each year, priced in excess of $449,950
  • Everything is bigger in Texas – New Hennessey 6x6 is terrifyingly imposing, monstrously capable, and unthinkably fast

SEALY, Texas, April 19, 2022 /PRNewswire/ -- Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has started building its biggest ever truck, the 1,012 bhp, 283-inch (719 cm) long Hennessey Mammoth 1000 6x6 TRX.

At almost seven feet high and 88 inches wide, the enormous 6x6 pickup truck dwarfs ordinary cars and trucks. It has the power to match its presence, with Hennessey's engineers boosting performance of the stock Dodge Ram TRX engine by more than 300 horsepower to 1,012 bhp. The torque needed to propel the monster truck is enhanced similarly, totaling 969 lb-ft (1,314 Nm) after a 319 lb-ft (433 Nm) uplift by Hennessey.

Alongside performance upgrades, the new truck features a mountain of off-road kit from locking rear axles and Bilstein suspension, to 20-inch wheels clad in 37-inch off-road tires. The 6x6 Mammoth builds on the base Ram TRX adding a third axle, extending the truck's length by more than four feet and creating a cavernous load-space.

John Hennessey, company founder and CEO: "Everything we do at Hennessey Performance is turned up to 11, but the Mammoth 1000 6x6 is definitely turned up to 12! Everything on the Mammoth 6x6 is bigger, badder, and more imposing – plus, it's still super-fast, while being a total powerhouse off-road. It's the undisputed king of the road."

Priced from $449,950 – inclusive of the base Ram TRX – the four-door Mammoth 6x6 features uprated front and rear bumpers and a dazzling array of LED lights alongside a bespoke interior, which adds to the exclusivity of this special vehicle. Under the chest-height hood, the truck features a mighty 6.2-liter Hellcat V8 engine – a beast even in stock form. The Hennessey team builds on this foundation adding a high-flow 2.65L supercharger, fuel injectors and high-flow induction system alongside performance-boosting calibration.

Hennessey has a track record of success when it comes to gigantic and exclusive 6x6 trucks. The company has built and delivered more than 20 VelociRaptor 6x6 and Goliath 6x6 Silverado trucks to clients all around the world. This solid performance in the three-axle world has its foundation in the highest standards of customer satisfaction, with Hennessey priding itself on the quality of its vehicles and workmanship. Underscoring this dedication to quality and customer car, all Hennessey models are offered with extensive warranties. The Mammoth is no different, benefitting from comprehensive 2-year / 24,000-mile cover.

Available for global shipping, the new Hennessey Mammoth 1000 6x6 TRX can be ordered now through authorized Ram retailers or directly with Hennessey, by calling +1 979.885.1300 or visiting HennesseyPerformance.com.

About John Hennessey
As the company founder and CEO, John Hennessey lives and breathes fast, fun cars. John developed a passion for performance while competing at world-renowned motorsport events including Pikes Peak, the Silver State Classic, and the Bonneville Salt Flats (where he set a class world record).
