Fuel economy numbers for the Jeep Grand Cherokee vary significantly based on engine choice and drivetrain configuration. If you are wondering how many mpg does a jeep grand cherokee get, the answer depends on which model year and engine you choose.
This article breaks down the real-world MPG ratings for every major Grand Cherokee engine option. We cover the V6, V8, diesel, and the new 4xe plug-in hybrid. You will also learn how driving habits and terrain affect fuel economy.
How Many Mpg Does A Jeep Grand Cherokee Get
The short answer is that a modern Jeep Grand Cherokee gets between 19 and 24 miles per gallon combined. However, the exact number changes with the engine. The most fuel-efficient version is the 4xe plug-in hybrid, which offers up to 57 MPGe in electric mode. The least efficient is the 6.4-liter V8, which averages around 15 MPG combined.
Below, we break down the MPG ratings for each engine option from the 2021 to 2024 model years. These numbers come from official EPA testing and real-world owner reports.
3.6-Liter Pentastar V6 Engine
This is the most common engine in the Grand Cherokee. It produces 293 horsepower and is paired with an eight-speed automatic transmission.
- Rear-wheel drive (RWD): 19 city / 26 highway / 22 combined
- Four-wheel drive (4WD): 18 city / 25 highway / 21 combined
In real-world driving, most owners report around 20 to 23 MPG combined. Highway cruising at 65 mph can yield 26 MPG or slightly higher.
5.7-Liter HEMI V8 Engine
The V8 offers more power (360 horsepower) but lower fuel economy. It comes standard with cylinder deactivation to save gas during light load.
- RWD: 14 city / 22 highway / 17 combined
- 4WD: 14 city / 21 highway / 16 combined
Real-world numbers are often lower, especially in stop-and-go traffic. Many owners report 14 to 16 MPG combined. Towing a trailer can drop this to 10 MPG or less.
6.4-Liter HEMI V8 Engine (SRT And Trackhawk)
This high-performance engine is found in the SRT and Trackhawk models. It produces 475 to 707 horsepower. Fuel economy is not a priority here.
- SRT (475 hp): 13 city / 19 highway / 15 combined
- Trackhawk (707 hp): 11 city / 17 highway / 13 combined
Expect single-digit MPG under hard acceleration. Even gentle driving rarely exceeds 16 MPG.
3.0-Liter EcoDiesel V6 Engine
The diesel option was available from 2014 to 2020. It offers excellent highway fuel economy for a large SUV.
- 4WD: 21 city / 28 highway / 24 combined
Many owners report 26 to 30 MPG on long highway trips. The diesel engine also provides strong low-end torque for towing.
4Xe Plug-In Hybrid (2022 And Newer)
The 4xe combines a 2.0-liter turbocharged four-cylinder engine with an electric motor. It offers up to 26 miles of all-electric range.
- Combined MPGe (electric + gas): 57 MPGe
- Gas-only mode: 23 MPG combined
- Electric-only range: 26 miles
If you charge regularly and drive short distances, you can achieve over 50 MPGe. Without charging, it operates as a conventional hybrid and gets about 23 MPG.
Factors That Affect Your Real-World MPG
EPA ratings are a guideline, not a guarantee. Several factors can lower your actual fuel economy.
Driving Habits
Aggressive acceleration and high-speed driving reduce MPG significantly. The Grand Cherokee is heavy, so smooth throttle inputs help.
- Avoid rapid acceleration from stops
- Use cruise control on highways
- Maintain steady speeds between 55 and 65 mph
Tire Pressure And Maintenance
Underinflated tires increase rolling resistance. Check your tire pressure monthly. Also, replace air filters and use the recommended oil viscosity.
Weight And Cargo
Extra weight reduces MPG. Remove roof racks when not in use. Avoid carrying unnecessary items in the cargo area.
Weather And Terrain
Cold weather reduces fuel economy by 10 to 20 percent. Hilly terrain also lowers MPG compared to flat roads.
How To Improve Your Jeep Grand Cherokee MPG
You can take simple steps to maximize fuel economy without changing your driving style drastically.
- Use the correct octane fuel. Most engines run fine on regular 87 octane. Check your owner’s manual.
- Keep up with maintenance. Oil changes, spark plugs, and air filters all affect MPG.
- Lighten the load. Remove heavy items from the trunk or cargo area.
- Check tire pressure weekly. Inflate to the pressure listed on the driver’s door jamb.
- Use the stop/start system. The Grand Cherokee has an auto stop/start feature that saves fuel at idle.
- Plan your route. Avoid heavy traffic and stop-and-go conditions when possible.
Comparing Grand Cherokee MPG To Competitors
How does the Grand Cherokee stack up against other midsize SUVs?
- Ford Explorer: 20-24 MPG combined (2.3L EcoBoost)
- Honda Pilot: 19-22 MPG combined (3.5L V6)
- Toyota 4Runner: 16-17 MPG combined (4.0L V6)
- Chevrolet Tahoe: 15-20 MPG combined (5.3L V8)
The Grand Cherokee’s V6 is competitive with the Explorer and Pilot. The diesel version was one of the most efficient options in its class. The 4xe plug-in hybrid leads the segment in fuel economy when charged regularly.
Real-World Owner Reports
We collected data from Jeep forums and owner surveys to give you a realistic picture.
- 2018 Grand Cherokee Limited (V6, 4WD): Owner reports 21 MPG combined over 40,000 miles.
- 2020 Grand Cherokee Trailhawk (V6, 4WD): Owner averages 19 MPG with off-road tires.
- 2021 Grand Cherokee L (V6, 4WD): Owner gets 20 MPG combined with three rows.
- 2022 Grand Cherokee 4xe: Owner reports 45 MPGe with daily charging, 22 MPG on long trips.
These numbers align closely with EPA estimates. The biggest variable is driving style and terrain.
