The EPA estimates the 2018 Ford Expedition 4WD with the 3.5L EcoBoost engine gets 19 MPG combined. This figure, while seemingly modest, is actually quite respectable when you consider the Expedition’s purpose: to haul up to eight passengers and tow substantial loads with confidence. Owners of this vehicle aren’t primarily focused on squeezing every last mile out of a gallon; they need space, power, and capability, and the Expedition delivers those.

City and highway performance

The EPA breaks down the Expedition’s fuel economy further, estimating 17 MPG in city driving and 22 MPG on the highway. The city figure reflects the expected penalties of stop-and-go traffic and the vehicle’s weight. The highway number demonstrates the efficiency of the 3.5L EcoBoost V6 and 10-speed automatic transmission once it settles into a cruising gear. Unlike some older large SUVs, the Expedition doesn’t suffer as dramatically when taken out of its ideal environment. The 10-speed transmission constantly works to keep the engine in its optimal power band, improving fuel economy whether you’re navigating urban sprawl or cruising down the interstate.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Ford Expedition 4WD with the 3.5L engine is $2,300. This figure is calculated based on driving 15,000 miles per year and using the national average fuel price. Individual fuel costs will vary depending on driving habits, location, and fuel prices in your area. While $2,300 might seem high, consider the alternatives: a minivan might offer better fuel economy but cannot match the Expedition’s towing capacity or off-road capability. For buyers who require the Expedition’s specific skill set, this fuel cost may be an acceptable trade-off.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy often varies. Factors such as driving style, terrain, and vehicle load can significantly impact MPG. Aggressive acceleration and frequent hard braking will decrease fuel efficiency. Towing, even occasionally, will have a notable effect. While some drivers may achieve the EPA estimates under ideal conditions, others may find their average MPG slightly lower. Regularly monitoring your fuel consumption and adjusting driving habits can help you get closer to the EPA figures.

How it compares

The 2018 Ford Expedition’s fuel economy places it competitively within its segment. The Chevrolet Tahoe 4WD with the 5.3L V8 is rated at 18 MPG combined, placing it slightly behind the Expedition. The Nissan Armada, with its larger 5.6L V8, achieves just 14 MPG combined, making it a considerably less fuel-efficient option. Even the Toyota Sequoia, another V8-powered competitor, only manages 15 MPG combined. For buyers prioritizing fuel economy within the full-size SUV class, the Expedition offers a balance of capability and efficiency. It’s important to cross-shop against other models but remember that each has its own compromises and rewards relative to the Expedition.

Tips to maximize efficiency

Minimize aggressive driving. The Expedition’s turbocharged engine delivers plenty of power, but using it excessively will quickly deplete your fuel tank. Smooth acceleration and consistent speeds are key to maximizing fuel economy. Anticipate traffic flow and avoid unnecessary braking.

Keep your tires properly inflated. Under-inflated tires increase rolling resistance, which forces the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended level, typically found on a sticker inside the driver’s side door jamb. Consider using the “Auto” setting for the 4WD system in normal driving conditions on paved roads; engaging 4-high when not needed reduces fuel economy.

Reduce excess weight. Carrying unnecessary cargo adds extra strain on the engine and lowers fuel efficiency. Remove any items from the vehicle that aren’t needed for the trip, especially heavy items. Empty roof racks or cargo boxes also improve aerodynamics.

Consider using cruise control on the highway. Maintaining a consistent speed can help optimize fuel consumption, especially on long highway drives. Cruise control helps prevent unintentional acceleration and deceleration, which can waste fuel. However, be mindful of traffic conditions and disengage cruise control when necessary to maintain safe following distances.
