Hennessey Mammoth Is a Crazy 1,000hp Pickup-Based Luxury SUV

If you need 1,000hp in your pickup, and you want your truck converted into a luxury SUV, then the Hennessey Mammoth 1000 is just the model for you.

Built around the Ram 1500 TRX, an American-market pickup truck that already packs an eye-catching 702hp under the bonnet, Hennessey engineers upgrade the supercharger system and recalibrate the 6.2-litre V8 petrol engine to boost power by 310hp, taking it up to 1,012hp. Torque is boosted from an already impressive 881Nm to an earth-shattering 1,314Nm.

That power results in remarkable performance, with the Mammoth accelerating to 60mph more quickly than many supercars, taking just 3.2 seconds.

Surprisingly, off-road capabilities haven’t been forgotten, with the Mammoth receiving an off-road package that includes a 63mm lift, a custom front bumper with LED lights, 20-inch 10-spoke wheels, 35-inch off-road tires, and a front suspension levelling kit.

More significant changes to the Ram TRX include bespoke bodywork to extend the roofline to meet a new C-pillar that sits above the rear taillights, turning the full-size pickup into a seven-seat SUV. The conversion incorporates a sizable rear-side window and adds a rear screen while retaining excellent luggage space behind the third row of seats.

“I have a big family with five kids and have always enjoyed owning big, powerful SUVs,” explained John Hennessey, company founder and CEO. “In 2012 we converted the first-generation Ford Raptor into our VelociRaptor SUV – I still own one today and love it. Now, we are excited to offer something very similar, but with a lot more horsepower, using the new Ram TRX truck as our base vehicle. Creating this king of SUVs offers our customers the ultimate combination of space, power and exclusivity.”
