Listen to the Hennessey Performance Hellcat V8 in the 2020 Jeep Gladiator Maximus. This video demonstrates what a 1,000 horsepower sounds like in this limited-edition. The tuned Gladiator more than triples the output of factory settings.
The purpose of the video is to attempt to measure the difference between the engine output and what’s measured at the rear wheels. This video examines multiple angles of the Maximus and the engine hitting 692 horsepower at 6,200 rpm and nearly 693 pound per feet of torque at 3,500 rpm on a dyno. Hennessey estimates a 30% driveline loss from the net published horsepower figure. Driveline loss is the difference between the manufacture standard of horsepower and the output measured at the wheels. It’s determined by the design of the transmission and other driveline components, and it grows the more with more friction, drag, intertidal and other factors.
The upgrades include larger, 20-inch wheels with big, all-terrain tires, heavy-duty off-road axles, custom front and rear differentials, plus the supercharged 6.2-liter Hellcat V8 upgraded to get 1,000 hop and 933 pound per feet of torque at the crank. The lifted the Maximus six inches, plus an upgraded fuel system, custom tuned stainless steel exhaust, an upgraded radiator and a Hellcat eight-speed automatic.
This upgrade will cost a pretty penny, Hennessey is charging $225,000 for the Maximus and limiting production to just 24 examples.
