The 2021 Jeep® Gladiator – the most capable Jeep truck ever – offers the most torque and best driving range with the introduction of the 3.0-liter EcoDiesel V-6 engine.

The expected fuel economy ratings will deliver the highest driving range on one tank of fuel ever for Gladiator.

The new 3.0-liter EcoDiesel V-6 engine, rated at 260 horsepower and 442 lb.-ft. of torque, with engine stop-start (ESS) technology standard, is available on Gladiator Sport, Overland and Rubicon models.

To handle greater torque loads, the EcoDiesel V-6 connects to a newly added TorqueFlite 8HP75 eight-speed automatic transmission, calibrated for low RPM shifts and the on- and off-road rigors of Jeep Gladiator duty.

There are more than 40 individual shift maps to optimize shift points for fuel economy, performance and 4×4 capability.

Jeep Gladiator EcoDiesel Sport, Overland, and Rubicon models feature third-generation Dana 44 front and rear heavy-duty axles.

Additionally, all Gladiator EcoDiesel models feature a 3.73 axle ratio. The Rock-Trac two-speed transfer case with a 4.0:1 low-range gear ratio is standard on Rubicon models and the Command-Trac part-time two-speed transfer case with a 2.72:1 low-range gear ratio on Sport and Overland models.
