18 MPG combined from the 2018 Ford Expedition MAX 4WD with the 3.5L EcoBoost V6 isn’t going to win any awards, but it’s what you get for needing its capabilities. This isn’t a vehicle for fuel savers; it’s for large families hauling kids and cargo, or for those towing boats, campers, and trailers. Efficiency comes second to size and power.

City and highway performance

The EPA estimates the 2018 Expedition MAX 4WD at 16 MPG in the city and 21 MPG on the highway. The difference between city and highway numbers shows how stop-and-go traffic affects this heavy SUV. The 10-speed automatic transmission, called “S10” in the EPA data, makes the most of the EcoBoost engine’s power, but physics matter. Acceleration is strong, even at lower RPMs, but each stop and start requires energy to overcome the vehicle’s mass. On the open road, the Expedition MAX settles into a more efficient cruise thanks to its aerodynamic shape and the transmission’s ability to select the best gear. Expect the highway MPG to drop when loaded with passengers and cargo, or when towing.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2018 Ford Expedition MAX 4WD at $2,450. This is based on driving 15,000 miles per year using the EPA’s combined MPG estimate and national average fuel prices at the time of calculation. Your actual fuel costs will vary based on your driving habits, local fuel prices, and the type of fuel you use. Using premium fuel, even though it’s not required, could change this figure, and longer road trips will as well.

Real-world expectations

The EPA figures provide a standard, but real-world fuel economy often differs. Many 2018 Ford Expedition MAX 4WD owners report numbers slightly below the EPA estimates, especially in mixed driving conditions. Aggressive driving, frequent short trips, and consistent heavy loads will reduce fuel economy. On the other hand, careful driving on long highway stretches may allow drivers to meet or even slightly exceed the EPA highway number. Don’t expect Prius-like efficiency, but there’s a reasonable range of change around that 18 MPG combined figure.

How it compares

Compared to its rivals, the 2018 Ford Expedition MAX 4WD is about average. A Chevrolet Suburban 4WD, for example, typically achieves around 17 MPG combined with its V8 engine. The Nissan Armada 4WD, another competitor in the full-size SUV segment, delivers approximately 15 MPG combined. Even the smaller Jeep Grand Cherokee 4×4 with its V6 engine sees only about 21 MPG combined in Trailhawk trim. For those who want less gas above all else, a minivan like the Honda Odyssey (22 MPG combined) or the Chrysler Pacifica (22 MPG combined) offers significantly better mileage, but less towing capacity and off-road capability. Buyers considering all Ford fuel economy data often weigh these trade-offs based on what they need. Also, compare the EXPEDITION MPG across all years to see how this compares to models from other years.

Tips to maximize efficiency

Aggressive acceleration and hard braking reduce fuel economy. The Expedition MAX responds well to a smooth, controlled driving style. Watch traffic and avoid sudden changes in speed to save fuel. Every time you step hard on the accelerator, the EcoBoost engine uses a lot of fuel, so be gentle with the right pedal.

Proper tire inflation is important for fuel efficiency. Check your tires regularly and keep the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which makes the engine work harder and burn more fuel. Proper tire inflation also helps tires wear evenly.

Reduce weight if you can. The Expedition MAX is already a large vehicle, so don’t carry extra cargo that you don’t need. Removing unused items from the cargo area and passenger seats can improve fuel economy, especially during city driving. Also consider removing roof racks when not in use, as they can increase drag.

Avoid idling. Letting the engine idle for a long time uses fuel without going anywhere. If you expect to stop for more than a minute, turn off the engine. Modern engines start quickly, so restarting the engine uses less fuel than idling.

Use cruise control on the highway. Keeping a constant speed minimizes acceleration and deceleration, which can improve fuel economy on long trips. Cruise control helps you keep a steady pace, reducing driver fatigue and helping you use fuel more efficiently. Remember to turn it off in heavy traffic or bad weather.
