Hennessey Performance Engineering (HPE), the Texas-based hypercar manufacturer and high-performance vehicle builder, has started production of the world’s most powerful pickup truck, the Hennessey MAMMOTH 1000 TRX with its upgraded 6.2-liter supercharged Hellcat V8 boasting 1,012 hp.

Based on the 702 hp Dodge Ram 1500 TRX pick-up truck, the high-performance-focused enhancements by Hennessey cut the 0-60 mph time to just 3.2 seconds – the quickest in the world – while torque grows to 969 lb-ft. With modifications including a high-flow 2.65L supercharger, fuel injectors and high-flow induction system alongside performance-boosting calibration, the 6.2-liter V8 truck can achieve an 11.4-second quarter mile at over 120 mph.

John Hennessey, company founder and CEO: “The new MAMMOTH 1000 TRX is the most powerful pickup truck that Hennessey Performance has ever offered. The Ram TRX already boasts the highest horsepower of any vehicle manufacturer’s pickup, so our performance, styling and off-road enhancements make this the most formidable new truck you can buy. We’ve already sold more than 100 trucks, with each answering one big question – why have a 1,000-horsepower pickup truck? Because we can!”

Measuring 228.9 inches (5.81 meters) long, 82.1 inches (2.09 meters) wide and 77.6 inches (1.97 meters) high, the imposing hypertruck makes an enormous statement on the road. Capable of carrying six adults in comfort, carrying a payload exceeding 2,300 lbs and towing more than 7,700 lbs, the Mammoth is the most comprehensive and capable performance truck on the market.

Including buying the stock TRX, owners opting for the Mammoth 1000 will typically pay in the region of $150,000 for their build. The majority of owners will take a highly-specified stock model, and add the Mammoth 1000 package and the Stage 2 off-road enhancements. The popular Stage 2 package adds custom bumpers, LED lights, a front levelling kit, 37-inch off road tires and upgraded electronic fold-out steps. The Mammoth 1000 TRX complete turnkey package also comes with a 2 year / 24,000-mile warranty.
