The Hennessey Mammoth is a 6×6 truck with prehistoric performance that has just started production.
Hennessey is known for performance trucks, SUVs, and sometimes for adding an extra set of wheels to the back of certain vehicles. However, the new Hennessey 6×6 Mammoth shows them turning a Ram truck into an entirely different animal. Adding an axle to the truck was just the beginning of what Hennessey did to make the Mammoth the truck that it is. It’s nearly 7 feet high, over 7 feet wide, and nearly 24 feet long. And similarly large, under the hood sits a 6.2-liter Hellcat V8, with upgrades that make it simply unbelievable.
Adding a 2.65-liter supercharger, the Hellcat engine has been brought up in performance to make a total of 1,012 horsepower, and 969 lb/ft of torque. All of this fearsome power goes to all six wheels for a truck that is both massive and fast, both on and off the road. The best part about all of this is the fact that Hennessey’s expertise and experience in 6×6 trucks make them confident in the reliability of the Mammoth to the point of offering a 2-year/24,000-mile cover on every Mammoth that is sold, which are able to be ordered now through Ram retailers or directly with Hennessey. Starting at just under $450,000, the Mammoth might be one of the most expensive trucks ever, but it’s one of the most incredible trucks just the same.
