Sealy, Texas (November 17, 2022) – Hennessey, the Texas-based hypercar manufacturer, and high-performance vehicle creator, has introduced an overlanding upgrade for its MAMMOTH TRX truck. The comprehensive package enables the world’s most powerful pickup truck to take adventure-oriented owners further into the wild than ever before.

Overlanding is vehicle-based, on-road and off-road adventure travel with a focus on self-reliance, resilience, and enjoyment of the journey – getting there is half the fun. With that in mind, the Hennessey MAMMOTH 1000 TRX offers adventurers 1,012-horsepower of 4×4 go-anywhere performance combined with everything needed to be comfortable in the remote backwoods.

The tailored Overland Edition includes a wide range of user-friendly equipment for truck-based living. The modular system utilizes a robust TRX bed rack as its foundation, topped by a convenient hard-shell rooftop tent that takes mere minutes to set up. A retractable 55-inch awning provides shade and shelter, while auxiliary fuel tanks and a pressurized water reservoir are also mounted on the rack to increase range and utility. Other accessories include a 28-inch splitting axe, shovel, and LED perimeter illumination. Grab handles, and a retractable ladder improve accessibility to the tent and equipment. 

The new Overland Edition is available on the company’s ‘MAMMOTH 900’ or ‘MAMMOTH 1000’ versions of the RAM TRX. Professionally installed by Hennessey Performance technicians, the comprehensive upgrade can be added to any MAMMOTH build for $19,950.

The MAMMOTH 1000 TRX is celebrated as the world’s fastest and most powerful truck. This performance comes courtesy of its 6.2-liter supercharged ‘Hellcat’ V8 enhanced with Hennessey’s high-flow 2.65L supercharger, larger fuel injectors, and high-flow induction system alongside performance-boosting calibration modifications. The upgrades result in a go-anywhere truck with 1,012 bhp @ 6,500 rpm and mountainous torque of 969 lb-ft @ 4,200 rpm.

John Hennessey, company Founder, and CEO: “Our new MAMMOTH 1000 TRX Overland Edition is the ultimate adventure-oriented vehicle as it adds off-the-grid capability to the world’s most powerful pickup. Thanks to the modular convenience of the system and its seamless integration, explorers may travel to remote areas and effortlessly set up camp without compromising performance or 4×4 capability. There’s nothing else like it!”

Measuring 228.9 inches (5.81 meters) long, 82.1 inches (2.09 meters) wide, and 77.6 inches (1.97 meters) high, the imposing Hennessey supertruck makes an enormous statement on- or off-road. Capable of carrying five adults in first-class comfort and towing more than three tons, the MAMMOTH is the most comprehensive and capable performance overlanding truck on the market.

Overlanding customers will typically specify Hennessey’s Stage 2 off-road enhancement package for their TRX. This package adds robust custom bumpers, vision-boosting LED lights, a front leveling kit, gnarly 37-inch off-road tires, and upgraded electronic fold-out steps. The MAMMOTH 1000 TRX Overland with Stage 2 upgrades also benefits from Hennessey’s comprehensive three-year / 36,000-mile warranty.
