What happens when the already boundary breaking Ram TRX falls into the hands of legendary automotive tuner, John Hennessey? A beast of mammoth proportions is born. The Ram TRX 1500 Hennessey Mammoth 1000 is the official apex predator of the truck world. Jurassic Park fans will understand when I say Hennessey brilliantly took a truck named after the mighty Tyrannosaurus Rex and mutated it into Abdominus Rex proportions.

For those unfamiliar with Hennessey Performance Engineering, they are an American tuning house that specializes in modifying sports cars, pick-up trucks and sports utility vehicles from a variety manufacturers. Established in 1991, their headquarters in Sealy, Texas has produced some amazingly powerful vehicles.  Their first build, the Hennessey Venom 650R, a package upgrade for the 1996 Dodge Viper, made it one of the fastest legal cars in the world with a top speed of over 215mph!  Every monstrous creation released by Hennessey has become bigger and badder than the one before.

From CEO and Founder John Hennessy’s interview with The Speed Journal, “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!”

The Mammoth 1000 easily leaves Hennessey’s Velociraptor 600 Ford Raptor begging for mercy.  The undisputed tyrant of trucks is the world’s fastest and most powerful producing 1,012 horsepower from its supercharged 6.2L Hemi V8 HELLCAT engine. The fuel injectors and high-flow induction system add performance-boosting calibration which breathes life into this on-road/off-road beast. 

If you need to outrun a velociraptor, or secure bragging rights from the truck lords, you need to own the  only pick-up truck in the world that can complete a quarter mile run in 11.4 seconds.  Roaring to life, the Mammoth 1000 boasts 969 pound-force feet of torque to go from 0 to 60 mph in just 3.2 seconds. Clearly, Hennessey created a game changer with the TRX Mammoth making it the fastest and most powerful pick-up truck in the world.
