If you’re looking for Jeep Gladiator diesel information, you’re not alone. Many truck fans want a pickup that combines Jeep’s rugged style with the fuel-saving power of diesel. But does Jeep actually make a diesel Gladiator? Here’s everything you need to know, including specs, comparisons, and practical tips.
Jeep Gladiator Diesel: Fact Or Fiction?
Yes, Jeep does offer a diesel-powered Gladiator. The model is called the Jeep Gladiator EcoDiesel, and it was first introduced for the 2021 model year. This truck is built for those who want strong torque, good towing, and better fuel economy compared to gasoline engines. Not every trim has the diesel option, but popular ones like the Sport, Overland, and Rubicon do.
Ecodiesel Engine Details
The Gladiator’s diesel engine is a 3.0-liter V6 EcoDiesel. It is designed by Fiat Chrysler Automobiles (FCA) and is used in other vehicles like the Ram 1500 and Jeep Wrangler. Here’s a quick look at what this engine offers:
| Feature | EcoDiesel V6 | Gas V6 |
|---|---|---|
| Horsepower | 260 hp | 285 hp |
| Torque | 442 lb-ft | 260 lb-ft |
| Transmission | 8-speed automatic | 6-speed manual or 8-speed automatic |
| Towing Capacity | 6,500 lbs | 7,650 lbs |
| Fuel Economy (Combined) | 24 mpg | 19 mpg |
Compared to the gas engine, the EcoDiesel offers more torque and better fuel economy, making it ideal for towing and off-road driving.

Performance And Real-world Benefits
The EcoDiesel Gladiator is known for its low-end torque, which means strong pulling power at lower speeds. This is great for:
- Towing trailers or boats
- Climbing steep hills
- Driving off-road
Drivers often report that the diesel feels smoother and more powerful when hauling heavy loads. It’s also quieter than many expect, with less engine noise on the highway.
One practical insight: the EcoDiesel is heavier than the gas version. This can make handling feel different, especially in off-road situations. Also, the diesel engine costs more up front, but may save money in the long run if you drive a lot.
Trim Levels And Features
You can get the diesel Gladiator in these trims:
- Sport
- Overland
- Rubicon
Each trim has its own features, but the diesel option adds about $4,000 to the price. Here’s a quick comparison:
| Trim | Diesel Option | Key Features |
|---|---|---|
| Sport | Yes | Basic off-road, cloth seats, manual windows |
| Overland | Yes | More comfort, touchscreen, advanced tech |
| Rubicon | Yes | Extreme off-road, locking differentials, heavy-duty suspension |
Some trims may have restrictions or require extra packages for the diesel engine, so check with your dealer.

Comparing Diesel Vs. Gas Gladiator
Why would you choose diesel? Here are the main differences:
- Diesel engine gives better fuel economy and more torque, but costs more to buy and maintain.
- Gas engine is cheaper, offers more horsepower, and has higher towing capacity in some trims.
For drivers who tow often or drive long distances, diesel can be a smart choice. For city driving and occasional off-road trips, gas may make more sense.
Let’s compare real-world usage:
| Scenario | Diesel Gladiator | Gas Gladiator |
|---|---|---|
| Daily Commute | Lower fuel costs, smooth ride | Lower initial cost, quicker acceleration |
| Towing | Strong torque, easy hauling | Higher tow rating, but less torque |
| Off-Road | Better control, more torque | Lighter, easier handling |
Practical Tips And Common Mistakes
If you’re thinking about buying a diesel Gladiator, keep these points in mind:
- Diesel engines require DEF fluid (diesel exhaust fluid), which needs regular refilling.
- Maintenance can be more expensive, especially for oil changes and repairs.
- Not every gas station sells diesel, so plan your routes.
- Some buyers forget to factor in the higher upfront price versus possible long-term savings.
One non-obvious insight: diesel Gladiators hold their value well, but resale can depend on regional demand. In states with strict emissions, diesel trucks may face extra rules or fees.
Is The Diesel Gladiator Still Available?
As of 2024, Jeep still offers the diesel Gladiator, but rumors suggest it may be discontinued soon. The push for electric and hybrid vehicles is changing the market.
If you want a diesel Gladiator, it’s smart to act quickly, as future models may drop the option.
