The Jeep Gladiator is a unique midsize pickup truck that stands out for its off-road skills, rugged design, and connection to the legendary Jeep Wrangler. One of the big questions many buyers and fans ask is: What diesel engine is in the Jeep Gladiator?
Understanding the engine choice is important if you want a truck with power, efficiency, and towing strength. Let’s break down the details, performance, and how the Gladiator’s diesel compares to other options.
Diesel Engine In The Jeep Gladiator
The Jeep Gladiator offers a 3.0-liter EcoDiesel V6 engine. This engine is well-known across the Jeep and Ram lineup for its balance of power and fuel efficiency. Here are the key specs:
- Displacement: 3.0 liters
- Configuration: V6, turbocharged
- Horsepower: 260 hp @ 3,600 rpm
- Torque: 442 lb-ft @ 1,400 rpm
- Transmission: 8-speed automatic
This engine was available on the Gladiator from the 2021 model year, giving buyers a strong alternative to the gas V6. It is not available on all trims; mainly, it is offered on the Sport, Overland, and Rubicon models.
Why Choose The Diesel?
The EcoDiesel V6 is popular with buyers who need extra torque for towing, hauling, or off-road adventures. Diesel engines typically deliver their peak torque at low RPMs, making them ideal for tough tasks.
Another reason to choose the diesel is its improved fuel economy. Owners often see better mileage than with the standard gasoline engine, especially when carrying heavy loads or driving long distances.
Performance And Efficiency
Let’s compare how the diesel stacks up against the gasoline engine commonly found in the Gladiator. Here is a simple data table for quick comparison:
| Engine | Horsepower | Torque | Towing Capacity | EPA MPG (city/hwy) |
|---|---|---|---|---|
| 3.0L EcoDiesel V6 | 260 hp | 442 lb-ft | 6,500 lbs | 22/28 |
| 3.6L Gas V6 | 285 hp | 260 lb-ft | 7,650 lbs | 17/22 |
As you can see, the diesel gives up a bit of towing capacity compared to the gas V6 but gains a lot of torque and much better fuel economy, especially on the highway.
Real-world Usage
Drivers who spend a lot of time on the highway or use their Gladiator for towing tend to favor the EcoDiesel. The extra torque makes pulling trailers or boats easier and smoother. For off-road fans, the low-end power helps on rocky trails or steep climbs.
A non-obvious point: Diesel engines like the EcoDiesel can be noisier at idle, but they are often quieter and smoother once moving. Also, owners should be aware that diesel engines require diesel exhaust fluid (DEF) and regular maintenance for the emissions system.
Trim Levels And Diesel Availability
Not every Gladiator trim comes with the diesel option. Here’s a quick overview:
| Trim | Diesel Available? | Key Features |
|---|---|---|
| Sport | Yes | Entry-level, manual option |
| Overland | Yes | Comfort-focused, tech upgrades |
| Rubicon | Yes | Off-road hardware |
| Mojave | No | Desert-rated, gas only |
| High Altitude | No | Luxury features, gas only |
If you want the diesel, focus on Sport, Overland, or Rubicon trims. The Mojave and High Altitude trims only come with the gas engine.
Comparing The Gladiator Diesel To Other Trucks
The Jeep Gladiator EcoDiesel competes with other midsize trucks like the Chevrolet Colorado and GMC Canyon, which also have diesel options. However, some rivals, like the Toyota Tacoma or Ford Ranger, do not offer diesel engines in the US.
Here’s how the Gladiator’s diesel compares with the Colorado’s diesel:
| Truck | Diesel Engine | Horsepower | Torque | Max Towing |
|---|---|---|---|---|
| Jeep Gladiator | 3.0L V6 | 260 hp | 442 lb-ft | 6,500 lbs |
| Chevrolet Colorado | 2.8L I4 | 181 hp | 369 lb-ft | 7,700 lbs |
The Gladiator’s diesel is stronger in horsepower and torque, but the Colorado can tow a bit more. If torque for off-roading is your priority, the Jeep has an edge. For pure towing, Colorado leads.
Common Buyer Considerations
If you’re thinking about the diesel Gladiator, here are a few things you should keep in mind:
- Price: The diesel engine costs extra, usually around $4,000 more than the gas V6.
- Maintenance: Diesel engines need special oil and DEF, which can add to service costs.
- Fueling: Diesel fuel is sometimes more expensive, and not every gas station has it.
- Emissions: Modern diesels have systems that need periodic cleaning or service.
- Resale Value: Diesel trucks often hold their value better, especially if you take good care of them.
A tip many new buyers miss: Test-drive both engines if you can. The feel of a diesel is different, especially the way it delivers power. Also, ask about warranty coverage for the diesel engine, as it sometimes differs from the gas version.
The Future Of Diesel In The Gladiator
As of 2023, Jeep has not announced plans to update or expand the diesel offering in the Gladiator. Diesel engines face tougher emission rules, and some automakers are moving to hybrid or electric powertrains.
If you want a diesel Gladiator, it may be wise to buy sooner rather than later, as future models may not offer this option.
