Jeep Wrangler MPG [by Engine Size & Year]

The Jeep Wrangler is an iconic off-road SUV known for its rugged capability and open-air freedom. However, when it comes to fuel efficiency, Wranglers have historically lagged behind other SUVs.

In recent years, Jeep has made efforts to improve the Wrangler’s MPG through new engine options and technologies. Read on for an overview of Jeep Wrangler fuel economy across different models and engine configurations.

In general, most Jeep Wrangler models achieve an EPA-estimated fuel economy of around 17-22 mpg city and 21-29 mpg highway, depending on configuration. These numbers are on the lower end for SUVs, where the class average is closer to 22 mpg city and 28 mpg highway. However, the Wrangler makes up for mediocre fuel economy with excellent off-road performance.

One factor that significantly impacts Wrangler MPG is the engine. Jeep offers three main engine options: a 3.6L V6, a 2.0L turbocharged 4-cylinder, and a 3.0L turbodiesel V6. The diesel achieves the best fuel economy, followed by the 2.0L turbo 4-cylinder. The V6 has the lowest MPG ratings.

Jeep has also developed a plug-in Wrangler 4xe model, which uses a hybrid powertrain to achieve a fuel economy rating of 49 MPGe (miles per gallon equivalent) from the EPA. This makes it the most efficient Wrangler yet in terms of MPG, although it comes at a higher price.

In recent model years, Jeep has implemented other enhancements to boost Wrangler fuel economy across the lineup. These include an improved 8-speed automatic transmission, start-stop technology to prevent idling, and weight reduction measures through increased use of aluminum. As a result, even V6 models have shown small MPG gains compared to older Wranglers.

Keep reading for a detailed breakdown of Jeep Wrangler MPG figures by engine type and model year. Fuel economy can vary significantly depending on configuration, so this guide will help you understand what to expect.

Jeep Wrangler MPG by Engine Type

One of the biggest factors determining Jeep Wrangler fuel economy is the engine under the hood. Let’s take a closer look at MPG for each of the Wrangler’s engine offerings.

2.0L Turbocharged 4-Cylinder

The 2.0L turbocharged 4-cylinder engine became available for the 2018 Wrangler JL generation. This engine replaces the older 3.2L V6 and 2.4L 4-cylinder options. Rated at 270 horsepower and 295 lb-ft of torque, the 2.0L turbo delivers a good balance of power and efficiency.

EPA fuel economy estimates for Wranglers equipped with the 2.0L turbo engine are:

1. City driving: 22 mpg
2.  Highway driving: 24 mpg
3.  Combined average: 22 mpg

These numbers apply across JL Wrangler Unlimited and 2-door models from 2018 to 2023 equipped with the 2.0L turbo engine and 8-speed automatic transmission. The turbo 4-cylinder gives a nice bump in MPG compared to the V6, while still providing capable acceleration and torque for off-road driving.

3.6L Pentastar V6

The 3.6L Pentastar V6 is Jeep’s workhorse engine, offered in Wranglers from 2012 through current 2023 models. It provides an optimal blend of power, torque, and affordability. Rated at 285 horsepower and 260 lb-ft of torque, this engine performs well both on-road and off.

EPA estimates for the 3.6L V6 depend slightly on Wrangler configuration:

1. 2-door with 6-speed manual: 17 mpg city / 23 mpg highway
2. Unlimited with 8-speed automatic: 18 mpg city / 24 mpg highway
3. Combined average ranges from 19-21 mpg

While not as efficient as the turbo 4-cylinder, the V6 delivers strong acceleration and can handle tough off-road terrain. The addition of the 8-speed automatic transmission in recent years has helped improve highway mpg.

3.0L EcoDiesel V6

Seeking maximum fuel economy in a Wrangler? Look no further than the 3.0L EcoDiesel V6, introduced for the 2020 model year. This turbocharged diesel generates 260 horsepower and a hefty 442 lb-ft of torque – the most torque of any Wrangler engine.

The EcoDiesel achieves EPA ratings of:

1. City: 22 mpg
2. Highway: 29 mpg
3. Combined: 25 mpg

These are the best MPG figures of any Wrangler configuration. The diesel’s higher compression and turbocharging translate to increased efficiency with lower RPMs compared to a gas engine. The added torque also improves trail performance. The diesel does add more upfront cost over a gas V6 or 4-cylinder.

4xe Hybrid System

New for 2021, the Wrangler 4xe models represent Jeep’s first foray into hybrid powertrains. 4xe Wranglers use a 2.0L turbo 4-cylinder engine paired with two electric motors and a 17 kWh battery pack. Total system output is 375 horsepower with max torque of 470 lb-ft.

In electric-only mode, the 4xe can travel up to 21 miles with zero emissions. EPA fuel economy estimates for gas and electric operation combined are:

1. MPGe: 49 (miles per gallon equivalent)
2.  Electricity consumption: 74 MPGe
3.  Gasoline fuel economy: 20 mpg combined

The 4xe achieves the best MPG of any Wrangler when factoring in electric operation. However, it comes at a higher purchase price. 4xe models also retain the same off-road capability as conventional Wranglers thanks to sophisticated 4×4 systems.

Jeep Wrangler MPG by Model Year

In addition to engine configuration, fuel economy for the Jeep Wrangler has improved slightly in recent model years through transmission upgrades, reduced weight, and other enhancements. Here is an overview of MPG by model year:

Early Jeep Wrangler MPG

In the 2000s, Jeep Wrangler fuel economy was quite poor, generally ranging from 15-19 mpg combined. These models were equipped with a variety of engine options, including:

1. 2.4L 4-cylinder – 152 hp / 165 lb-ft
2.  2.8L diesel I4 – 115 hp / 229 lb-ft
3.  4.0L PowerTech I6 – 190 hp / 235 lb-ft
4. 3.8L V6 – 202 hp / 237 lb-ft

All engines were paired exclusively with a 4-speed automatic transmission, except the 4.0L which had a 6-speed manual option. This contributed to low MPG along with the boxy shape and heavy off-road components.

2012-2018 Jeep Wrangler MPG

The introduction of the Pentastar 3.6L V6 in 2012 helped increase Wrangler fuel economy to EPA estimates of 16 mpg city / 20 mpg highway – respectable numbers for an old-school, body-on-frame 4×4. These figures applied for both 2-door and Unlimited models through 2018.

Other engines offered during this period:

1. 3.6L V6 with 6-speed manual: 17 mpg combined
2. 3.8L V6 with automatic: 16 mpg combined
3. 2.8L diesel with automatic (export only): 19-21 mpg combined

So while the 3.6L brought a welcome improvement, there was still room for progress in Wrangler fuel efficiency.

2018+ Jeep Wrangler JL MPG

The fully redesigned 2018 Jeep Wrangler JL generation brought several enhancements targeting better fuel economy:

1. Addition of 2.0L turbo 4-cylinder with 8-speed auto achieving 22 mpg combined
2.  Upgraded 8-speed auto for 3.6L V6 improving highway mpg
3.  Reduced weight via increased use of aluminum
4. Improved aerodynamics with removable top and windshield
5. Start-stop technology to prevent idling

As a result, even the V6 saw a mild bump with EPA estimates up to 19 mpg city and 24 mpg highway for Unlimited models. These small but meaningful MPG gains have continued across 2019 to 2023 JL models.

Future Jeep Wrangler MPG

We can expect further fuel economy improvements in future Wrangler generations. The 4xe plug-in hybrid model points the way forward, achieving 49 MPGe when factoring in electric operation.

As battery costs decrease, more advanced hybrid systems will likely make their way to the Wrangler platform. However, future Wranglers will always prioritize off-road prowess over efficiency. Diesel and turbo engines should also continue improving the MPG of gas-powered models.

Real-World vs EPA Estimated MPG

The EPA fuel economy figures discussed provide a useful baseline for comparing vehicles. But how does Jeep Wrangler MPG hold up in actual on-road driving conditions?

Generally, most drivers report achieving real-world gas mileage within 2-3 mpg of EPA combined estimates. However, driving style, terrain, payload, and other factors can cause actual results to vary widely.

Based on user-submitted data to sites like Fuelly.com, current model year Wranglers average 1-2 mpg lower in city driving compared to EPA ratings. However, highway mpg is often closer or even slightly better than estimated – especially with the V6 and diesel engines.

Off-road and towing situations take an inevitable toll on Wrangler fuel economy. Even casual off-roading can reduce MPG noticeably depending on the difficulty of the terrain. Towing heavy loads also cuts into fuel efficiency significantly.

On the positive side, there are steps owners can take to maximize real-world Wrangler MPG:
