For many drivers, the word “Jeep” brings to mind adventure, ruggedness, and the freedom to explore. But for those who want powerful torque and better fuel economy, one question often comes up: Does Jeep make a diesel engine?
The answer is more interesting than you might think. While diesel engines are common in trucks and some SUVs, their story within the Jeep brand is unique, filled with both innovation and recent changes.
Let’s dig into Jeep’s relationship with diesel power, what models have offered it, and what you should know if you’re thinking about a diesel Jeep.
Jeep’s Diesel Engine History
Jeep has a long history of experimenting with diesel engines. The company first tried diesel in the 1980s, mostly for export markets where diesel was more popular. In the United States, diesel Jeeps have always been rare but have become more popular in recent years due to growing interest in off-road towing and efficiency.
In the modern era, Jeep introduced its EcoDiesel engine in the Grand Cherokee in 2011 (outside the US) and later brought it to the US market in 2014. The real breakthrough came when Jeep added diesel to the Wrangler and the full-size Gladiator pickup.
Jeep Models With Diesel Engines
Not every Jeep has had a diesel option. The main models with diesel power are:
- Jeep Grand Cherokee EcoDiesel: First available in the US for the 2014 model year.
- Jeep Wrangler EcoDiesel: Launched for the 2020 model year.
- Jeep Gladiator EcoDiesel: Introduced in 2021.
These diesel engines offered strong towing power and better fuel economy compared to their gasoline versions.
Here’s how some key specs compare:
| Model | Diesel Engine | Horsepower | Torque (lb-ft) | Towing Capacity (lbs) |
|---|---|---|---|---|
| Grand Cherokee | 3.0L EcoDiesel V6 | 240-260 | 420 | 7,200 |
| Wrangler | 3.0L EcoDiesel V6 | 260 | 442 | 3,500 |
| Gladiator | 3.0L EcoDiesel V6 | 260 | 442 | 6,500 |
Key Benefits Of Diesel Jeeps
Diesel-powered Jeeps have some clear advantages over their gasoline counterparts:
- Higher torque: Diesel engines produce more torque at lower RPMs, which helps for towing and off-road climbs.
- Better fuel economy: Diesel Jeeps can travel farther on a tank of fuel, especially on highways.
- Longer engine life: Diesel engines are built strong and are known for lasting many miles.
- Towing power: The extra torque is ideal for pulling trailers, boats, or heavy gear.
However, there are some trade-offs, which we’ll explain next.
Diesel Vs Gasoline: Pros And Cons
Choosing between a diesel and a gasoline Jeep depends on your needs. Here’s a comparison to help you decide:
| Aspect | Diesel | Gasoline |
|---|---|---|
| Torque | High (good for towing) | Lower |
| Fuel Economy | Better (especially highway) | Good (city driving) |
| Engine Noise | Louder | Quieter |
| Maintenance | May be higher cost | Usually lower |
| Purchase Price | Higher | Lower |
| Availability | Limited models | All models |
One insight many new buyers miss: Diesel engines can have more expensive repairs if something goes wrong. The savings on fuel may be offset if you drive only a few miles per year or keep the vehicle for a short time.
Why Diesel Jeeps Are Becoming Rare
Jeep’s diesel offerings have been shrinking. In 2023, Jeep announced the end of the EcoDiesel engine for both the Wrangler and Gladiator in the US. The Grand Cherokee dropped its diesel option a few years earlier. This shift is mostly due to:
- Stricter emissions standards: Diesel engines face tough rules, making them expensive to upgrade.
- Focus on electrification: Jeep is moving toward hybrid and fully electric vehicles.
- Changing customer demand: More buyers now prefer gasoline or hybrid for smoother driving and lower emissions.
As of 2024, you can no longer buy a new Jeep with a diesel engine in the US. However, used diesel Jeeps are still available, and diesel options may still be offered in some international markets.
What To Consider Before Buying A Diesel Jeep
If you’re thinking about a diesel Jeep, here are some key points:
- Fuel availability: Diesel is common at most US gas stations but not as widespread as gasoline.
- Cold weather: Diesel engines can be harder to start in freezing temperatures, though modern models are much better than older ones.
- Resale value: Used diesel Jeeps often hold their value well because they are rare and in demand by towing or off-road fans.
- Emission equipment: Diesel engines have extra systems like DEF (diesel exhaust fluid) tanks, which require regular refills and maintenance.
A tip many buyers overlook: Test-drive both diesel and gasoline versions if you can. Some drivers prefer the smoother, quieter ride of gasoline, while others love the torque and fuel savings of diesel.
The Future Of Diesel In Jeep Vehicles
Jeep’s parent company, Stellantis, is investing heavily in plug-in hybrids and electric vehicles. The popular Jeep Wrangler 4xe is a plug-in hybrid, combining electric power with a turbocharged gasoline engine. This trend means we are unlikely to see new diesel Jeeps in the US for the foreseeable future.
Still, Jeep’s history with diesel engines has left a mark. In many countries, diesel-powered Jeeps are valued for their range, power, and efficiency. For those who need to tow heavy loads or travel long distances between fill-ups, a used diesel Jeep can still be a smart choice.

Frequently Asked Questions
Does Jeep Still Make Diesel Engines In 2024?
No, as of 2024, Jeep does not offer any new vehicles with diesel engines in the United States. The last models with diesel—the Wrangler and Gladiator—ended production in 2023.
Which Jeep Models Had Diesel Engines In The Us?
The main models were the Jeep Grand Cherokee EcoDiesel, Wrangler EcoDiesel, and Gladiator EcoDiesel. Some older Jeep Libertys also had diesel options for a short time.
Are Diesel Jeeps Good For Off-roading?
Yes. Diesel Jeeps offer more torque at low speeds, which is great for climbing and tricky trails. Many off-road fans choose diesel for this reason.

The Jeep Wrangler EcoDiesel can get up to 29 miles per gallon (mpg) on the highway, according to EPA estimates. This is much better than the gasoline V6 or V8 options.
Can I Buy A Used Diesel Jeep?
Yes, used diesel Jeeps are available. They often have higher resale value due to their towing power and rarity.
Always check the maintenance history, especially for emission systems and DEF usage.
Whether you’re looking for rugged off-road ability or strong towing for your next adventure, understanding Jeep’s diesel history helps you make the best choice. While new diesel Jeeps are no longer available in the US, their legacy continues for fans who value power, efficiency, and durability.
