Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has started building its biggest ever truck, the 1,012 bhp, 719 cm long Hennessey Mammoth 1000 6×6 TRX.
At almost seven feet high and 88 inches wide, the enormous 6×6 pick-up truck dwarfs ordinary cars and open back 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, totalling 1,314 Nm after a 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 tyres. The 6×6 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.
To explain John Hennessey, company founder and CEO said: “Everything we do at Hennessey Performance is turned up, but the Mammoth 1000 6×6 is definitely turned up to max! Everything on the Mammoth 6×6 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 6×6 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 6×6 trucks. The company has built and delivered more than 20 VelociRaptor 6×6 and Goliath 6×6 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.
