Less than two-weeks after Ram unleashed its Raptor-eating TRX 1500 super-truck in August of 2020, Hennessey Performance Engineering unveiled a 1,200hp 7.0L Hellephant-engined 6×6 version of the mighty TRX. Fast forward to today and HPE has returned to the TRX to deliver its latest ultra-high-performance pickup, the 2021 Hennessey MAMMOTH 1000 Supercharged.
Thanks to an upgraded 2.65L supercharger, pulley system, a high-flow exhaust system with stainless steel headers, and new HPE calibration, the HPE-built TRX offers a 310hp (and 319ft-lbs) bump in power, resulting in an output of 1,012hp and 969ft-lbs of torque. And, on top of being one of the most exclusive Hennessey-built Ram trucks, the MAMMOTH 1000 is also the quickest, with the ability to fire off standing quarter-mile runs in under 11.5 seconds and 0-60mph stints in just 3.2-seconds. Costing over $65K more than the regular TRX 1500, the new super-truck has also been gifted a STAGE 1 off-road package with a 2.5” lift kit and a front suspension leveling kit, a custom front bumper with integrated LED lights, 20” Hennessey ten-spoke wheels wrapped in 35” all-terrain tires, a retractable electronic bed cover, electronic fold-out steps, and HPE and MAMMOTH 1000 badging inside and out. Limited to 200 units, the 2021 Hennessey MAMMOTH 1000 Supercharged RAM TRX Super Truck is available for preorder now, with pricing starting from $135,350.
