We are currently living in an era of unrivaled automotive performance. The fact that you can buy several different vehicles with 700+ horsepower on tap from your local Stellantis dealer is outrageous by any metric. The fact that one of those vehicles comes in the shape of an off-road conquering pickup truck almost seems like an impossibility. And yet the Ram 1500 TRX is quite real, with 702 horsepower and 650 lb-ft of torque on tap from its supercharged 6.2L Hellcat V8. Most buyers will be more than satisfied with this level of performance, but John Hennessey isn’t a normal customer. That is why Hennessey Performance Engineering has just announced their new Hennessey Mammoth 1000.

As is normal when dealing with the tuner Texans at HPE, the Hennessey Mammoth 1000 takes the Ram 1500 TRX and cranks the knob up to 11. The rending may only be a concept at this point, but HPE has been quite clear about their intentions for the upcoming package. Output is slated to be raised to 1,012 horsepower and 969 lb-ft of torque thanks to an upgraded supercharged, a downsized pulley, a new engine tune, and a high-flow exhaust with stainless-steel headers. This will allow the Hennessey Mammoth 1000 to do 0-60 mph in just 3.2 seconds, making it the quickest Ram product Hennessey Performance Engineering has ever built. For comparison, a stock Ram 1500 TRX takes 4.5 seconds to complete a 0-60 mph dash.

The build doesn’t stop under the hood either. This particular concept has been fit with what HPE is calling their Off-Road Stage 1 package, and features a 2.5-inch suspension lift and leveling kit, 20-inch HPE wheels, as well as a new bull bar and LED light bar setup. Hennessey Performance Engineering badging has also been added to the windshield, the door panels, and the bulging hood. As the name might suggest, it is expected that HPE will roll out a few more packages above this Stage 1 offering down the line.

According to Hennessey, the total cost of getting into their new mega-Ram is $135,350 not including delivery. That is quite a bit of cash, but a TRX itself carries an MSRP of $71,690 from the factory. That investment does come with some added peace of mind thanks to a  2-year / 24,000-mile warranty from HPE. Would you spend that much extra cash for 300 extra horsepower? Let us know down below.
