The Jeep Gladiator was all-new for the 2020 model year, so don’t expect any huge and sweeping changes to Jeep’s only pickup truck for 2021. There are a few additions of note, however, and they are as follows:
Jeep added the 3.0-liter V-6 EcoDiesel to the Wrangler for 2020, so you knew it was only a matter of time before it made its way to Gladiator as well.
This engine will deliver 260 horsepower and 442 pound-feet of torque. The only transmission available will be the TorqueFlite 8HP75 8-speed automatic. Jeep says this is to handle the greater torque loads.

The only trim that doesn’t get the diesel: the Mojave.
One interesting thing to note: While you’re fuel economy goes up, your tank capacity goes down if you opt for diesel over gasoline. EPA estimates for the EcoDiesel are 24/28/22 mpg in city/highway/combined driving, compared to 17/22/19 mpg. But whereas the gas model has a 22-gallon fuel tank, the diesel only gets an 18.3-gallon tank.

For 2020, Gladiator was only available with the standard Sport, Sport S, Overland, Mojave and Rubicon models. For 2020, Jeep adds the 80th Anniversary and Willys models to the lineup, but they haven’t really given us too much information (or photos) from either model. Jeep officials say the reveal of both these models will be in the next month or so.
What we do know: The anniversary edition will feature 18-inch wheels with a Granite Crystal finish, Neutral Grey Metallic exterior accents, the up-level 8.4-inch touchscreen, Berber floor mats and commemorative exterior badging.
We assume the Willys model will be similar to the Wrangler Willys and we know it will feature a limited slip rear differential, rock rails and 32-inch mud-terrain tires.
Though Jeep hasn’t provided us with any pricing info for either model, we assume the Wyllis will slot in between the Sport S and Overland, and the 80th Anniversary model will be just below Rubicon and Mojave.

Previously, the Sport, Sport S and Mojave models only came equipped a part-time 4WD system. Now for 2021, all models will have full-time 4WD available. This Selec-Trac two-speed transfer case will deliver a 2.72:1 low-gear ratio. To differentiate, the Rock-Trac two-speed transfer case on the Rubicon provides a 4:1 low-range gear ratio.
The above items are the biggies, but there is also a smattering of updates and new features that will be included on the 2021 model. The two most notable changes: Overland models now offer the forward-facing off-road TrailCam camera, and Sport models now offer LED headlights and fog lights as optional equipment.

How is 2020 Jeep Gladiator reliability so far? Early reports suggest a consistent issue
That’s really odd that the diesel tank is so much smaller. To the best of my knowledge, that might be the smallest fuel tank of any truck on the market. I wonder if FCA had to make the tank smaller to accommodate a DEF tank too?
Fair point about the DEF tank. I wonder if other diesel tanks are similarly smaller. ? #RabbitHole
Just did a quick look at Silverado, and the tank is smaller, but not in the teens. Regular Cab has a 28.3-gallon fuel tank, Double & Crew have a 24-gallon tank. Diesel is a 22-gallon tank. ??♀️
That’s really interesting. I guess with the smaller diesel engines you don’t necessarily get the significantly longer range that you would expect given the fuel economy. The gladiator gas gets 484 miles to a tank highway while the diesel gets 512.4. Glad you pointed out the fuel tank size, I would have assumed that they would use the same size for diesel and gas
