2020 Hennessey Maximus 1000 Jeep Gladiator

Published By

Starting with a 2020 Jeep Gladiator, Hennessey Performance Engineering (HPE) created a monster. The 2020 Hennessey Maximus 1000 Jeep Gladiator is exactly what Hennessey company founder and chief horsepower evangelist, John Hennessey, says it is; “Badassery on 4-wheels”.

Unveiled at the 2019 SEMA show in Las Vegas, the Hennessey Jeep Gladiator Maximus has 1000 HP. The 6.2L supercharged V8 Hellcat engine, paired with an 8-speed automatic transmission, is capable of generating 933 lb-ft of torque. To go along with the increased performance, HPE also upgraded the ECU, wiring harnesses, radiator and fuel system. All these modifications lead to this Jeep pickup truck being capable of going 0-60 in 3.9 seconds. 

The Jeep exterior features MAXIMUS front and rear bumpers with LED lights. Continuing the aggressive styling are the Hennessey aluminum wheels and stainless steel exhaust system. This blacked out truck looks downright angry.


The Jeep Gladiator Hennessey Maximus 1000 features heavy-duty off-road axles with a KING off-road suspension system on a 6-inch lift. Equipped with BFG off-road tires and a 3-year/36,000 mile warranty, this beast of a truck is begging to be put to the test. The Maximus 1000 will pass the test with confidence. Any test.

For $225,000, this incredibly rare 2020 Hennessey Jeep Gladiator can be all yours. Unfortunately, production of the Maximus 1000 is limited to 24 units. John Hennessey said, “We wanted to create the ultimate Jeep Gladiator”. Congratulations John, you nailed it.
