Fuel Economy
In addition to the torque story, the diesel engine also delivers improved fuel economy. The 2021 Jeep Gladiator Rubicon Diesel has U.S. EPA fuel-economy ratings of 20 mpg city / 25 mpg hwy / 22 mpg combined. These numbers are an improvement of about 3 mpg vs. the 3.6-liter V6 gas engine, giving the Gladiator Rubicon Diesel a range of more than 450 miles. During our drive — a combination of on- and off-pavement adventuring — the Gladiator computer displayed around 24 mpg.
