• The Hennessey Mammoth 1000 SUV - The Ram Charger We Deserve With Supercar-Slaying Performance

The Ram TRX isn’t available in SUV guise, but Hennessey just made one

LISTEN 02:18

Hennessey just finished concocting the Mammoth SUV, which is essentially a Ram 1500 TRX turned into a seven-seater that packs 1,012 horsepower and can go from zero to 60 mph in 3.2 seconds. It just doesn’t get more Hennessey than that.

It’s hard to want more than what the stock Ram 1500 TRX pickup truck is already offering. 702 horsepower coming from a fire-breathing 6.2-liter supercharged Hellcat V-8 with 650 pound-feet of torque. All of that dispatched to all four corners sounds like the stuff off-roading dreams are made of, but not to Hennessey.

The Hennessey Mammoth doesn’t have a bed anymore. Instead, it was given a full body overhaul, but instead it doubles down on luxury and exclusiveness. Or at least that’s what Hennessey tells us. In any case, if you want to talk numbers, here’s the deal.

The Mammoth is now a five-door SUV but that’s not necessarily the only talking point.

It also has a $375,000 price tag and a heavily tuned engine that now makes 1,012 horsepower and 969 pound-feet of torque, which accounts for a 310-horesepower and a 319-pound-feet jump from the standard Ram TRX.

If that’s not enough to justify the asking price, know that the Mammoth needs just 3.2 seconds to zap from naught to sixty and just 11.4 seconds to destroy the quarter-mile at 120 mph. Hennessey also says you’ll be able to smoke out supercars in full comfort thanks to front and middle row captain’s chairs. The rear bench seat can be folded if you don’t plan to haul your kids arounds.

Speaking of which, kids is what inspired Hennessey to design the Mammoth, with John Hennessey admitting that “I have a big family with five kids and have always enjoyed owning big, powerful SUVs.”

In any case, Hennessey plans to build just 20 units of the Mammoth. Each will sit on 35-inch off-road tires and 20-inch Hennessey wheels. There’s also a front suspension leveling kit and custom bumpers, along with a three-year/36,000-mile warranty.

Tudor’s first encounter with cars took place when he was only a child. Back then, his father brought home a Trabant 601 Kombi and a few years later, a Wartburg 353. At that time, he was too young to know how they worked and way too young to drive them, but he could see one thing – each of them had a different ethos and their own unique personality. As time went on, he started seeing that in other cars as well, and his love for the automobile was born.  Read full bio
