Sealy, Texas (March 12, 2024) Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has announced a special edition ‘Last Stand’ Mammoth 1000 TRX to send off the world’s favorite hypertruck in style. The Texas team will offer the special edition V8-powered Ram TRX exclusively on 2024 model year trucks, which feature new colors and distinctive ‘Last Stand’ graphics.

December 2023 saw Ram produce the final 702 hp Dodge Ram 1500 TRX. The model was transformed in 2021 with the Hennessey team comprehensively upgrading the truck with high-performance focused enhancements. Hennessey cut the 0-60 mph time to just 3.2 seconds – the quickest in the world – while torque reached 969 lb-ft thanks to modifications including a high-flow 2.65L supercharger, and performance-boosting calibration, resulting in a hypertruck capable of an 11.4-second quarter mile at over 120 mph.

John Hennessey, company founder and CEO: “Our MAMMOTH 1000 TRX is a celebration of big, powerful, V8 combustion! Our customers love these trucks, their power, the sound of the V8, and the performance they’re capable of. So, it’s only right that we recognize the significance of the final models with our ‘Last Stand’ special edition. The MAMMOTH 1000 is already the world’s quickest and most exclusive production truck, now our limited run takes that exclusivity to a whole new level.”

The special edition ‘Last Stand’ model is available in three new colors – Harvest Sunrise Orange, Delmonico Red, and Night Edge Blue – as well as returning factory colors, including Pitch Black, Granite Grey, Billet Silver and Bright White. The Hennessey team further enhances the exclusivity of these special trucks by adding distinctive ‘Last Stand’ graphics to the rear fenders. Running the length of the truck’s load bed, the ‘Hennessey’ script leads into a black graphic that contours around the rear light cluster, which features a ‘Last Stand’ medallion.

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 engine, enhanced with Hennessey’s high-flow 2.65L supercharger, 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.

On top of Hennessey’s MAMMOTH 1000 performance upgrades, customers can opt for the Off-Road package, which adds custom bumpers, LED lights, 20-inch Hennessey 10-spoke wheels, 35- or 37-inch off-road tires, a front and rear leveling kit, plus electronic fold-out steps. Customers wanting to create the ultimate performance hypertruck can also opt for larger Wilwood performance brakes and an upgraded transmission. Every MAMMOTH 1000 TRX complete turnkey truck also comes with an industry-best three-year / 36,000-mile limited warranty.

Hennessey will ensure exclusivity for its customers by limiting production volumes of the MAMMOTH 1000 with each truck fitted with a special chassis plate recording its build number. To retain exclusivity, no more than 200 of the ‘Last Stand’ models will be produced for customers across the US and around the world. Orders can be placed through authorized Ram retailers or Hennessey directly by calling +1.979.885.1300 or visiting HennesseyPerformance.com.
