The 2023 Jeep Grand Wagoneer 4WD with the 3.0L Hurricane engine gets 17 MPG combined. No one buys a Grand Wagoneer expecting Prius-like efficiency. It’s a full-size, body-on-frame SUV with serious towing capacity and the kind of presence that makes other SUVs shrink. The target demographic prioritizes space, luxury, and capability, and they recognize that those qualities come at a price at the pump.

City and highway performance

The EPA estimates the Grand Wagoneer at 14 MPG in the city and 20 MPG on the highway. The 14 MPG city figure reflects hauling over 6,000 pounds through stop-and-go traffic. The turbocharged inline-six has to work hard to get the Grand Wagoneer moving. The 20 MPG highway figure is more respectable, aided by the eight-speed automatic transmission’s ability to settle into a fuel-efficient cruising gear. However, if you load it up with passengers and cargo, expect that highway number to dip considerably.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Jeep Grand Wagoneer 4WD at $3,400. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Your actual fuel expenses will vary depending on your driving habits, local fuel prices, and the specific blend of city and highway driving you do. Drivers with long commutes or those who frequently tow will likely exceed this estimate, while those who primarily use the Grand Wagoneer for shorter trips might find their annual fuel costs slightly lower.

Real-world expectations

While the EPA provides a standardized measure, what you experience can deviate. Grand Wagoneer owners report figures slightly below the EPA estimates, particularly in mixed driving. Aggressive driving, frequent short trips (where the engine never fully warms up), and using accessories like four-wheel-drive can all negatively impact fuel economy. Consistent highway driving at moderate speeds can often bring you closer to the 20 MPG highway rating.

How it compares

The Jeep Grand Wagoneer’s figures put it squarely in line with other full-size luxury SUVs. The Cadillac Escalade, for example, typically achieves similar fuel economy with its V8 engine, around 14 MPG city and 19 MPG highway. The Lincoln Navigator posts similar numbers. Even the more modern Range Rover, known for its focus on luxury, isn’t drastically more efficient, hovering around 18 MPG combined in its six-cylinder mild-hybrid variants. For buyers in this segment, the slight MPG differences are often less of a deciding factor than features, comfort, and brand cachet. Potential buyers can explore all Jeep fuel economy data to understand where the Grand Wagoneer sits within the broader Jeep lineup.

Tips to maximize efficiency

The 3.0L Hurricane engine benefits from smooth and consistent acceleration. Avoid aggressive starts and hard braking, as these actions waste fuel. Gradual acceleration allows the turbocharger to spool up efficiently and reduces the demand on the engine.

Tire pressure plays an important role in fuel economy. Ensure your tires are inflated to the pressure specified on the door jamb sticker. Underinflated tires create more rolling resistance, which forces the engine to work harder and consume more fuel. Check tire pressure regularly, especially in colder weather.

Minimize idling. The Grand Wagoneer’s engine consumes fuel even when stationary. If you anticipate being stopped for more than a minute or two, it’s more efficient to turn off the engine, especially in city driving. Restarting the engine consumes less fuel than prolonged idling.

Careful route planning can optimize fuel consumption. Combining errands into a single trip minimizes cold starts, which are less fuel-efficient. Avoiding congested routes and opting for highway driving over stop-and-go city streets can also improve your overall MPG.

Consider the driving mode. While the Grand Wagoneer excels in off-road situations, using four-wheel drive on paved roads increases fuel consumption. Ensure that the vehicle is in two-wheel drive mode when optimal traction isn’t needed, especially during dry conditions.
