The team at Hennessey Performance Engineering (HPE) has done it again. This Texas-based hypercar manufacturer and high-performance vehicle building just started production on the world’s fast and most powerful pickup truck. 

Get ready to see the Hennessey Mammoth 1000 TRX blast off. It’s based on the 2021 Ram 1500 TRX and has been enhanced to be a lot faster and a lot stronger. The Ram 1500 TRX provides 702 hp and 650 lb-ft of torque, by the way. 

How much power does the Mammoth 1000 TRX have? 

The Hennessey Mammoth 1000 TRX is powered by a 6.2-liter supercharged Hellcat V8 with 1,012 hp and 969 lb-ft of torque. That’s an incredible amount of extra power compared to the Ram 1500 TRX

Plus, the truck also received modifications such as a high-flow 2.65-liter supercharger, fuel injectors, a high flow induction system, and performance-boosting calibration. This Mammoth can accelerate from 0 to 60 mph in 3.2 seconds and achieve a quarter-mile in 11.4 seconds while going over 120 mph. 

Ancient mammoths that are now extinct creatures were thought to be slow, not super fast! But like the prehistoric beasts, the 1000 TRX is massive. It’s about 22.9-inches long, 82.1-inches wide, and about 77.6-inches tall. 

This massive hypertruck is hard to miss on the road. It has enough space for six adults to sit comfortably. It can tow up to 7,700 lbs and carry a payload of up to 2,300 lbs. It’s the largest and most capable performance truck available.

John Hennessey, company founder, and CEO sharted that the new Mammoth TRX is the most powerful truck that Hennessey Performance has ever offered. He’s pretty excited about it because the Ram 1500 TRX already boasts having the highest horsepower out of any vehicle manufacturer’s pickup. 

So the Hennessey performance, styling, and off-road enhancements make the Mammoth 1000 TRX the most formidable pickup truck you can buy. That’s why it’s already sold over 100 units. You better act fast. Only 200 units are being manufactured for 2021. 

You can place your order through authorized Ram retailers or Hennessey directly by calling 979-855-1300 or by visiting The Mammoth starts at about $150,000. That’s a lot more than the 2021 Ram 1500 TRX that has an MSRP of $70,325. 

You begin with a highly specified stock model, then add the Mammoth 1000 package. Some buyers may opt for the Stand 2 off-road enhancements, including custom bumpers, LED lights, a front leveling kit, 37-inch off-road tires, and upgraded electronic fold-out steps. The Mammoth 1000 TRX complete turnkey package adds a two-year/24,000-mile warranty. 

The Ram 1500 TRX already serves as an incredible off-roading truck, but you can make it even better by upgrading to the Hennessey Mammoth 1000 TRX. But hurry, these beasts are flying off the shelves.
