19 MPG combined is the price of admission to the full-size SUV club. The 2021 Ford Expedition 4WD with the 3.5L EcoBoost V6 isn’t trying to win any fuel sipping contests. It exists to haul families, tow boats, and conquer snowy driveways. Its drivers appreciate the refinement and capability, knowing efficiency comes second to these priorities. It’s a compromise for the space, power, and ruggedness the Expedition delivers.

City and highway performance

The EPA estimates suggest 17 MPG in the city and 22 MPG on the highway for this Expedition configuration. These numbers reflect the engine working across a wide range, from stop-and-go traffic to steady-state cruising. The Expedition’s weight and ample power from the 3.5L EcoBoost, sending power through a 10-speed automatic (S10), contribute to this difference. City driving suffers due to constant acceleration and braking, while highway driving benefits from the engine settling into a more efficient range. Drivers who spend significantly more time in one environment versus the other will see results that reflect that. Anyone needing to understand EXPEDITION MPG across all years will benefit from reviewing past fuel economy data.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Ford Expedition 4WD 3.5L is $2,300. This figure is calculated based on driving 15,000 miles per year, using the EPA’s combined MPG rating and assuming national average fuel prices. Remember that this is an estimate. Individual driving habits, local fuel costs, and even tire pressure can influence the actual amount spent. However, it provides a useful baseline for comparing this vehicle’s running costs to other options in the segment.

Real-world expectations

While the EPA provides a standardized measurement, real-world fuel economy often varies. Some Expedition owners report achieving numbers close to the EPA estimates, particularly on long highway trips with a light foot. Others, who frequently tow or spend most of their time in heavy traffic, see figures lower than the official ratings. The aggressive nature of the EcoBoost’s turbocharging system means that fuel consumption can rise dramatically if you constantly tap into its power. Also, remember that colder weather can impact fuel economy, especially in the winter months, typically reducing numbers 1-2 MPG compared to warmer months.

How it compares

The Expedition competes in a segment where fuel economy is rarely a selling point. The Chevrolet Tahoe 4WD with the 5.3L V8 nets an EPA-estimated 17 MPG combined. The Nissan Armada 4WD, known for its powerful V8, typically delivers 14-15 MPG combined. Even the Toyota Sequoia 4WD struggles to match the Expedition, often landing around 15 MPG combined, despite offering a less refined driving experience. The Jeep Wagoneer 4×4 typically comes in around 18 MPG combined. The Expedition’s 19 MPG places it near the top of its class. Anyone can research all Ford fuel economy data to understand the brand’s broader efficiency efforts. For buyers who require the capability of a full-size SUV, the Expedition offers a relatively efficient vehicle without compromising on performance or utility.

Tips to maximize efficiency

One of the easiest ways to save fuel is to adopt a smoother driving style. Avoid rapid acceleration and hard braking. The EcoBoost engine responds well to a gentle foot, allowing the turbos to spool up gradually and efficiently. Anticipating traffic flow and maintaining a consistent speed can also reduce fuel consumption.

Ensure your tires are properly inflated and regularly checked. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure. This is critical on a heavy vehicle like the Expedition.

Consider reducing the amount of weight you carry in the vehicle. Unnecessary cargo adds to the overall load, impacting fuel economy. Remove any items you don’t need, especially heavy objects like tools or sports equipment, to lighten the Expedition’s burden. Think whether you really need to carry those extra 100 pounds of equipment.

When possible, avoid idling for extended periods. If you’re waiting for someone or stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and easily. Idling consumes fuel without moving, and can significantly reduce your overall MPG, particularly in city driving. These moments add up quickly.

Plan your longer highway trips to avoid peak congestion. Stop-and-go traffic reduces fuel economy. Try to travel during off-peak hours, or consider using navigation apps to find routes with less traffic. Maintaining a consistent speed on the highway allows the engine to operate at its most efficient point, maximizing your fuel economy.
