It's pretty awesome this truck exists, even if there aren't going to be many of them

Hennessey’s 1,200 horsepower Mammouth 6X6 is insane, and you know you want one.

The Mammoth does away with the pedestrian 702 horsepower factory Hellcat V8 and replaces it with a specially-tuned 7.0-liter “Hellephant” crate engine. But that’s not all — this one’s been tuned to make over 1200 horsepower. Like the Ford VelociRaptor 6X6, this vehicle will be produced in limited numbers for a huge mountain of cash. In fact, only three of these trucks will be produced.

If you want one, you may have to fight a variety of celebrities who will order one this September. Keep in mind: Post Malone owns one of the VelociRaptors and he’s not about to say his Goodbyes to it anytime soon.

Here’s what CEO John Hennessey has to say about his company’s latest insane creation: “It will also be the most expensive with a cost of $500,000 which includes the base Ram TRX. The Mammoth 6X6 powered by a 1,200 horsepower Hellephant motor is just a completely ridiculous idea, which is exactly why we are doing this.” On top of the six-wheel drive conversion and the bespoke bed, the Mammoth 6×6 will have upgraded suspension, unique bumpers and a bespoke interior.

Hennessey will begin accepting the grand total of three orders starting on Sept 4, 2020 at noon Central Time. So, if you’re feeling flush, you can call (800) 897-0426 to place your order. Or, if you can’t get one, at least you can get one of the firm’s other ludicrous conversions.

Speaking of absolutely ridiculous vehicles built by Hennessey, check out their GM-powered Goliath. Then, take a breath and realize that the new Mammoth has double the horsepower.
