18 MPG combined places the 2025 Ford Expedition 4WD 3.5L 6-cyl squarely in the territory of full-size, body-on-frame SUVs, a vehicle segment defined by its substantial capabilities rather than its svelte fuel consumption. This figure isn’t a surprise for a behemoth designed to haul up to eight passengers and their gear, tow serious loads, and conquer rough terrain with an available four-wheel-drive system. Buyers drawn to the Expedition prioritize space, utility, and commanding presence above all else. They understand that moving this much mass requires significant energy, and for them, the trade-off for its unmatched utility is entirely justifiable. This isn’t a suburban runabout it’s a mobile command center, a family hauler for the adventurous, or a workhorse for those who need its raw strength.

City and highway performance

Looking closer at the numbers, the 2025 Expedition 4WD logs 15 MPG in the city and 22 MPG on the highway. The city figure, at 15 MPG, is the telling metric. Maneuvering nearly three tons of steel, plastics, and glass through stop-and-go traffic, often laden with passengers and cargo, is the ultimate test of any full-size SUV’s efficiency. The twin-turbocharged 3.5-liter EcoBoost V6, paired with Ford’s excellent 10-speed automatic transmission, works hard to get the Expedition moving from a standstill, and that’s where the most fuel is consumed. The highway rating of 22 MPG is more respectable, due to the efficient gearing of the 10-speed automatic and the EcoBoost engine’s ability to cruise at lower RPMs once up to speed. For families embarking on long-haul road trips, the highway economy provides some relief, stretching the interval between fuel stops more effectively than its urban performance. It’s a vehicle built for the open road, where its size becomes an asset in terms of comfort and stability, and its fuel efficiency slightly less of a penalty.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for the 2025 Ford Expedition 4WD 3.5L 6-cyl. This figure is calculated based on an average driving distance of 15,000 miles per year, split between 45% highway and 55% city driving, and using national average fuel prices. It serves as a useful benchmark for potential owners to understand the yearly budgetary impact of owning this particular full-size SUV. For buyers of the Expedition, this cost is generally accepted as a part of doing business. Someone consistently needing to transport seven or eight people, or tow a substantial boat or trailer, already recognizes that their vehicle choice comes with a higher operational cost than a compact crossover. The $2,450 is a tangible representation of the power and utility they demand, a necessary expense for the freedom and capability the Expedition provides.

Real-world expectations

Real-world fuel economy for any vehicle, especially one as large and capable as the Expedition, rarely perfectly mirrors EPA estimates. The 2025 Ford Expedition 4WD 3.5L 6-cyl is no exception. Drivers who regularly push the vehicle to its limits, frequent heavy towing, aggressive acceleration, or constant short city trips, can expect to see figures dip below the 18 MPG combined rating. Conversely, those with a lighter foot, who predominantly drive on open highways at consistent speeds, might even occasionally exceed the 22 MPG highway estimate. Factors like tire pressure, cargo weight, exterior accessories (like roof racks), and even the prevailing weather conditions will all play a role. When considering EXPEDITION MPG across all years, consistent heavy hauling will always be the primary driver of consumption for this platform. What’s guaranteed is the power from the EcoBoost V6, which delivers its 400+ horsepower and 480 lb-ft of torque (in most trims) with authoritative response, making light work of inclines and merging onto busy highways, even if it sips more fuel in the process.

How it compares

The 2025 Ford Expedition 4WD 3.5L 6-cyl exists in a competitive field of large, body-on-frame SUVs, where fuel economy is a secondary concern to capability. Its 18 MPGL combined rating puts it squarely in the thick of things. For instance, the Chevrolet Tahoe 4WD with its 5.3L V8 typically achieves 17 MPG combined (15 city/20 highway), making the Expedition slightly more efficient due to its turbocharged V6 and advanced 10-speed transmission. The larger Chevrolet Suburban 4WD with the same 5.3L V8 mirrors the Tahoe’s 17 MPG combined. The Toyota Sequoia 4WD, now exclusively with a hybrid powertrain, offers a more impressive 22 MPG combined (21 city/24 highway), but that comes with a different driving dynamic and price point. Meanwhile, the Jeep Wagoneer 4×4 with the 3.0L Hurricane Twin-Turbo inline-six matches the Expedition at 18 MPG combined (16 city/23 highway). This comparison highlights that while the Expedition isn’t a class leader in outright efficiency, it holds its own very well against direct, non-hybrid rivals, often besting them with its EcoBoost V6 technology. Buyers looking for all Ford fuel economy data will find the Expedition an honest contender within its segment.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the easiest and most effective ways to improve fuel economy in the Expedition. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure weekly, especially before longer drives.

Smooth driving habits can significantly impact the Expedition’s city MPG. Avoid jackrabbit starts and aggressive braking, instead opting for gradual acceleration and anticipating stops to coast when possible. This reduces the strain on the powertrain and minimizes wasted energy.

Use the Expedition’s drive modes effectively. Some models may offer an “Eco” mode, which adjusts throttle response, transmission shift points, and climate control settings to prioritize fuel efficiency over performance. Engage this mode when maximum power isn’t needed.

For those who frequently engage in towing, ensure your trailer is properly maintained and loaded. Correct tire pressure on the trailer, balanced weight distribution, and aerodynamic considerations for larger trailers can all contribute to better fuel economy during arduous journeys.

Minimize unnecessary weight. While the Expedition is built for hauling, regularly removing unused cargo, such as heavy tools or sports equipment, can reduce the load on the engine. Every pound requires energy to move, so lighten the load where you can.
