Hennessey Mammoth 6x6 RAM TRX Truck
Hennessey Performance Engineering (HPE) has unveiled the most powerful truck in the company’s 29-year history, or to be more specific, a 6X6 conversion of the 2021 Ram TRX truck. The factory 702 bhp Hellcat supercharged V8 will be replaced by a specially tuned 7.0L Hellephant engine generating over 1200 bhp. The Mammoth 6X6 will be limited to 3-units worldwide, and priced at a hefty $500,000 which includes the base Ram TRX. Read more for a video of their 800hp 6×6 Goliath and additional information.



Aside from the 6-wheel drive and all new truck bed conversion, this beastly truck will have a fully upgraded off-road suspension, custom interior, upgraded front / rear bumpers with upgraded LED lights and lots more.

We are very excited about the Ram TRX. MAMMOTH 6X6 powered by a 1200 HP Hellephant motor is just a completely ridiculous idea, which is exactly why we are doing this. We are only going to build three examples which will likely make this the most exclusive and most expensive truck we’ve ever built,” said company founder and CEO, John Hennessey.
