It has been over 30 years since we have had a diesel Jeep truck, and I wouldn’t call the French diesel-powered engine in the Comanche anything but completely horrendous. Although the mighty Jeep Comanche was the robust small pickup version of the beloved Cherokee XJ with a partial frame and bed, it has become a classic. Ever since then, Jeep enthusiasts have been begging for a truck and a diesel engine option – finally, their prayers have been answered. Jeep released the all-new Jeep Gladiator (JT) in late 2019, built on the all-new refined road-friendly Wrangler (JL) platform utilizing the 3.6 Pentastar V6 with the eight-speed automatic transmission available with a manual transmission. This year, they offer an EcoDiesel variant for the Gladiator available in the Rubicon trim, and people are excited. Could this be the answer to the enthusiast’s prayers, and is it any good off-road?
