21 MPG combined is a reasonable, if unremarkable, figure for the 2022 Jeep Grand Cherokee L 4WD with the 3.6L V6. It represents the compromise buyers make when they need three rows of seating, available off-road capability, and the inherent toughness that defines the Jeep brand. This isn’t a vehicle primarily chosen for its efficiency, it’s selected for its blend of utility, comfort, and a certain go-anywhere confidence that appeals to families who live active lifestyles and aren’t afraid of venturing beyond paved roads.

City and highway performance

The EPA estimates that the 2022 Grand Cherokee L 4WD achieves 18 MPG in the city and 25 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where a larger vehicle with a naturally aspirated V6 and four-wheel drive will inevitably consume more fuel. The highway number is more respectable. The eight-speed automatic transmission allows the engine to cruise at lower RPMs, along with active fuel management technologies, but it still lags some competitors due to the Grand Cherokee L’s weight and less aerodynamic profile. Drivers should also remember that the 4WD system, while delivering unmatched versatility, adds weight and some drivetrain friction compared to its 2WD counterparts.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 Jeep Grand Cherokee L 4WD 3.6L V6 is $2,100. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Individual spending on gasoline will vary depending on local fuel costs, driving habits, and the actual number of miles driven. Drivers who primarily use their Grand Cherokee L for short trips around town will likely exceed this figure, while those who do mostly highway driving might see slightly lower costs.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy often deviates. Factors like aggressive acceleration, carrying heavy loads, or frequently using the four-wheel-drive system will negatively impact fuel consumption. Weather conditions, such as driving in snow or extreme heat, can also play a role. Owners of the Grand Cherokee L 4WD should expect to see figures within a few MPG of the EPA estimates, but consistent adherence to efficient driving practices is critical to achieving optimal mileage. Many drivers also keep a close eye on tire pressures, as properly inflated tires reduce rolling resistance and contribute to improved fuel economy.

How it compares

The fuel economy of the 2022 Jeep Grand Cherokee L 4WD 3.6L V6 is competitive within its class, but there are certainly more efficient options available. For example, the Toyota Highlander Hybrid achieves up to 36 MPG combined, though it sacrifices some of the Jeep’s strong off-road capabilities. A comparable Ford Explorer with its 2.3L EcoBoost engine manages around 23 MPG combined, offering a slight improvement in efficiency. The Nissan Pathfinder, with its V6 engine, is similarly rated to the Grand Cherokee L. Buyers prioritizing fuel economy above all else might consider alternatives, but those who need the Jeep’s blend of capabilities are likely willing to accept the trade-off. For those just looking for GRAND MPG across all years, a look at older generations could also prove beneficial.

Tips to maximize efficiency

Smooth and steady acceleration is critical for maximizing fuel economy. Avoid sudden bursts of speed and try to maintain a consistent pace, especially in city driving. The Grand Cherokee L’s eight-speed transmission is designed to shift smoothly and efficiently, and gentle acceleration allows it to do its job effectively.

Minimize idling whenever possible. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and the fuel saved by avoiding idling can add up over time. For Jeep fuel economy data compared with the competition, do some research.

Keep your tires properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which leads to decreased fuel economy. Check your tire pressure regularly and inflate them as needed. Consult the sticker on the driver’s side doorjamb for the recommended pressure.

Reduce unnecessary weight in the vehicle. Carrying extra cargo adds strain on the engine and reduces fuel efficiency. Remove any items you don’t need, such as sports equipment or tools, to lighten the load.

Use the Grand Cherokee L’s available efficiency settings, if equipped. Some models offer an “Eco” mode that adjusts the engine and transmission settings to prioritize fuel economy. Experiment with these settings to see if they can improve your mileage without sacrificing performance.
