1000 HP Hellcat-Powered Jeep Gladiator to be Unveiled at the SEMA Show in Las Vegas

Sealy, Texas (October 30, 2019) — Hennessey Performance Engineering (HPE) has created the ultimate Jeep Gladiator: MAXIMUS. The Texas tuning powerhouse has taken the new Jeep Gladiator truck and installed the 6.2L supercharged V8 Hellcat engine and turned the power up to 11. Hennessey will unveil the company’s first production MAXIMUS, powered by PENNZOIL, on Wednesday, November 6, 2019 at the 2019 SEMA Show in Las Vegas at the Shell “Pioneering Performance” Experience (booth #60003).

“We wanted to create the ultimate Jeep Gladiator,” said company founder and chief horsepower evangelist, John Hennessey. “MAXIMUS 1000 – the name says exactly what it is: Badassery on 4-wheels. We are excited to unveil our first production MAXIMUS with the Shell Pennzoil team at the SEMA Show in Las Vegas.”
