The Gladiator is the only pickup truck that Jeep carries. It can be powered by the 3.6L Pentastar V6 gas engine (285 hp and 260 lb. ft.) or the 3.0L EcoDiesel V6 (260 hp and 442 lb. ft.). An eight-speed automatic transmission is available with either engine. However, the six-speed manual transmission can only be paired with the gas engine.
