What Size Engine Does The Jeep Gladiator Have: Complete Guide

The Jeep Gladiator stands out as a unique vehicle in today’s truck market. It combines the rugged spirit of a Jeep with the utility of a pickup.

For buyers, one of the first questions is simple: What size engine does the Jeep Gladiator have? The answer depends on the model year and trim.

Understanding the engine options will help you pick the right Gladiator for your needs, whether you plan to tow, off-road, or use it as a daily driver.

Engine Options In The Jeep Gladiator

Since its launch in 2019, the Jeep Gladiator has offered two main engine choices. Both engines are well-known in the Jeep lineup, but each brings different strengths.

3.6l Pentastar V6 Gas Engine

Most Gladiator models come standard with the 3.6-liter Pentastar V6. This engine is a workhorse in many Jeep and Chrysler vehicles. It produces:

• 285 horsepower
• 260 lb-ft of torque

The Pentastar V6 uses regular gasoline and features variable valve timing for better efficiency. It is available with either a 6-speed manual or an 8-speed automatic transmission. For most buyers, this engine provides a good balance of power and efficiency. It’s strong enough for towing and daily driving, and it keeps costs reasonable.

3.0l Ecodiesel V6 Engine

Jeep introduced the 3.0-liter EcoDiesel V6 in the Gladiator lineup starting in 2021. This engine is ideal for drivers who want more torque, especially for towing or off-roading. The key specs:

• 260 horsepower
• 442 lb-ft of torque

That torque number is much higher than the gas V6. This means the EcoDiesel can handle tough jobs, like pulling a trailer or climbing steep trails, with less effort.

The diesel engine is only available with the 8-speed automatic transmission.

Engine Comparison Overview

To make the differences clear, here is a comparison of both engines:

Which Engine Is Right For You?

Choosing between the Gladiator’s engines depends on what you need your truck to do. Here are some important factors to consider:

Power And Performance

If you want a classic Jeep feel with a strong V6, the 3.6L Pentastar is a solid choice. It’s responsive, has plenty of power for highway driving, and is available with a manual transmission. This engine is also less expensive and easier to maintain.

The 3.0L EcoDiesel shines if you need extra torque. High torque is useful for towing heavy loads or crawling over rocks. The diesel engine is also quieter on the highway and offers better fuel efficiency, especially for long trips.

Towing And Payload

The Gladiator is designed for work and play. Both engines offer strong capability, but there are differences:

• Maximum towing with 3.6L V6: Up to 7,700 lbs (when properly equipped)
• Maximum towing with 3.0L Diesel: Up to 6,500 lbs

Although the diesel has more torque, the gas V6 actually has a higher max towing rating, mainly due to how the truck is set up for each engine. However, the diesel’s high torque makes towing smoother and easier, especially at low speeds.

Fuel Economy

Fuel efficiency is a big consideration, especially for frequent drivers. The diesel engine is the clear winner here. According to the EPA:

• 3.6L Pentastar V6 (automatic): 17 mpg city / 22 mpg highway
• 3.0L EcoDiesel V6: 22 mpg city / 28 mpg highway

That’s a significant difference, especially on long trips or for daily commutes.

Off-roading

Both engines are strong off-road. However, the diesel’s high torque at low RPMs makes it excellent for rock crawling and steep climbs.

The Pentastar is lighter, which can help with balance and maneuverability.

Special Editions And Future Engine Options

Jeep sometimes releases special Gladiator editions with unique features, but the engine choices remain the same. There are rumors about future powertrains, such as a plug-in hybrid or even a turbocharged four-cylinder, but as of now, the V6 engines are the only options.

Some buyers hope for a Hemi V8 or a hybrid, but these are not available yet. If you want a V8 in a Jeep pickup, you must look at aftermarket conversions, which can be costly and affect your warranty.

Common Misconceptions

Many people assume that all trucks have a V8, but the Gladiator only offers V6 engines. Some also believe the diesel engine offers the highest towing, but in the Gladiator, the gas V6 actually leads in this area. Another surprise: the manual transmission is only available with the gas engine, not the diesel.

Real-world Example: Which Engine Do Owners Prefer?

Owner surveys and forums show a split. Most Gladiator buyers pick the gas V6 because it is cheaper, easier to find, and offers more transmission choices.

However, drivers who tow often or drive long distances appreciate the diesel for its torque and fuel savings.
