18 MPG combined isn’t going to win any efficiency awards, but the 2017 Ford Expedition 2WD with the 3.5L EcoBoost V6 isn’t about winning awards. It’s about moving a lot of people and cargo in relative comfort, and doing it reliably. The Expedition is a tool, and its fuel economy needs to be viewed in that context. Those who buy this vehicle understand that compromise and prioritize space and capability over lower fuel costs.

City and highway performance

The EPA estimates for the 2017 Expedition 2WD powered by the 3.5L EcoBoost V6 and six-speed automatic transmission are 15 MPG in the city and 21 MPG on the highway. The city figure reflects the strain of stop-and-go traffic on a vehicle that weighs nearly 5,500 pounds. Highway driving shows the effectiveness of the EcoBoost engine’s turbocharging, allowing it to cruise comfortably at higher speeds without excessive fuel burn. However, reaching that 21 MPG requires a gentle foot and a willingness to resist the temptation to exploit the engine’s ample power. The six-speed automatic is old by modern standards, and more gears would likely increase fuel economy to some extent, especially on the highway. You can always consult EXPEDITION MPG across all years to view fuel economy figures across the vehicle’s lifespan.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Ford Expedition 2WD 3.5L to be $2,450. This figure is calculated based on driving 15,000 miles per year, with a mix of city and highway driving, and using the EPA’s assumed national average fuel price. Your actual fuel costs may vary depending on your driving habits, location, and the current price of gasoline. It’s a significant number, but for many Expedition owners, it’s simply the cost of doing business.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can vary considerably. Factors like driving style, terrain, vehicle load, and tire pressure all play an important role. Aggressive acceleration, frequent braking, and carrying heavy loads will negatively impact fuel efficiency. Conversely, smooth driving techniques, proper tire inflation, and minimizing cargo weight can help you get closer to the EPA estimates, or even slightly exceed them. Most owners report seeing figures close to the EPA’s combined rating. Remember, the EcoBoost engine benefits greatly from a light foot. Pushing the engine hard will result in a dramatic drop in MPG.

How it compares

Compared to other large SUVs from the same model year, the 2017 Ford Expedition’s fuel economy is generally in line with its competitors. For example, the 2017 Chevrolet Tahoe 2WD with the 5.3L V8 is rated at 16 MPG combined (16 city/23 highway). The Nissan Armada, another popular choice, achieves 15 MPG combined (14 city/19 highway) with its 5.6L V8 and a heavy curb weight. The Toyota Sequoia, a more rugged, truck-based option, offers similar fuel economy figures around 15 MPG combined. While these differences may seem small, they can add up over time, especially considering the high annual mileage that many Expedition owners accumulate. Knowing these figures is important when evaluating where the Expedition sits in the broad spectrum of all Ford fuel economy data.

Tips to maximize efficiency

The EcoBoost engine in the 2017 Expedition responds well to smooth and consistent throttle inputs. Avoid aggressive acceleration and hard braking whenever possible. Anticipate traffic flow and maintain a steady speed to minimize fuel consumption. The turbochargers are there to provide power when needed, but constant boosting drains fuel quickly.

Proper tire inflation is critical for maximizing fuel efficiency. Check your tire pressure regularly and ensure it matches the recommended pressure listed on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, which negatively impacts fuel economy. Using the correct tire pressure also optimizes tire wear and handling.

Reduce unnecessary weight in the vehicle. Carrying excessive cargo adds strain to the engine and decreases fuel efficiency. Remove any items you don’t need, such as tools, sports equipment, or other heavy objects. Every extra pound counts, especially in a vehicle of this size.

Consider using cruise control on the highway. This feature helps maintain a consistent speed, minimizing fluctuations that can waste fuel. However, be mindful of terrain and traffic conditions; disengage cruise control if you need to accelerate or decelerate frequently.

Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, is essential for optimal fuel efficiency. A well-maintained engine runs more smoothly and efficiently, which translates to better MPG. Neglecting maintenance can lead to decreased performance and increased fuel consumption.
