The 2021 Ram 1500 TRX boasts a factory-quoted 702 hp and 650 lb-ft of torque, but which is as measured at the crank, not the wheels. Hennessey Functionality Engineering experimented with to measure how a lot electrical power the TRX helps make at the wheels by strapping 1 to a dyno, but only ran numbers for the rear wheels.

The dyno check showed 538 hp and 570 lb-ft of torque at the rear wheels. That represents close to 17% driveline reduction, which is not unusal for a pickup truck. Hennessey previously recorded twenty% driveline reduction at the rear wheels when it examined a 2019 Ford F-150 Raptor.

The TRX is complete-time 4-wheel drive, so you may possibly be questioning how Hennessey received dyno final results for the rear wheels only. Organization founder John Hennessey advised Motor Authority that 4-wheel drive was temporarily disabled by disconnecting the front driveshaft.

Whilst the TRX was developed for off-roading, the sum of electrical power made by its six.two-liter supercharged Hellcat V-eight helps make this truck fairly rapid on pavement. Ram says it will do -60 mph in four.five seconds.

Inevitably, that was not ample for Hennessey. The business has produced much more effective versions of each Hellcat-powered automobile, and it truly is performing the exact same with the TRX. Dubbed the Mammoth one thousand, Hennessey claims its consider on the TRX will boast one,000 hp, will do -60 mph in three.two seconds, and run the quarter mile in eleven.four seconds.

To obtain individuals numbers, Hennessey programs to equip the Mammoth one thousand with an upgraded supercharger, pulley, and air consumption, stainless-steel headers, higher-movement exhaust piping (retaining the catalytic converter), and new engine mapping. The price tag for the full truck is $135,350, and Hennessey only programs to construct 200 this 12 months.
