21 MPG combined is a fuel economy figure that should be accepted, for the 2021 Ford Explorer RWD with its 3.0L 6-cylinder engine. This isn’t a fuel-sipping hybrid; it’s a reliable, rear-wheel-drive SUV designed for hauling families and cargo, often over long distances. Buyers of this Explorer configuration prioritize space, power, and a traditional SUV driving experience over saving money at the pump. They understand the trade-off.

City and highway performance

The EPA estimates place the Explorer RWD 3.0L at 18 MPG in the city and 26 MPG on the highway. The city figure reflects the stop-and-go conditions that penalize larger, heavier vehicles. The 26 MPG highway number is more reasonable, showcasing the engine’s efficiency at sustained speeds. Reaching that 26 MPG consistently requires a mindful driving style and avoiding heavy loads or aggressive acceleration. Towing, even within the Explorer’s limits, will dramatically reduce fuel economy on either type of road.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Ford Explorer RWD 3.0L 6-cyl at exactly $2,100. This figure is calculated based on driving 15,000 miles per year, using the EPA’s combined fuel economy rating, and assuming a national average fuel price. A driver who spends more time in city traffic or regularly exceeds 15,000 miles annually will likely see that annual cost increase, potentially significantly. Someone who predominantly drives on the highway and keeps their mileage lower might spend less. Fuel prices fluctuate too.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates. Owners report a range of experiences, influenced by factors like driving habits, terrain, and vehicle maintenance. Expect the actual combined MPG to fluctuate between 19 and 23 MPG in typical use. Aggressive acceleration, frequent short trips, and neglecting maintenance will push the number toward the lower end. Gentle driving, consistent highway cruising, and staying on top of scheduled service can help achieve figures closer to the EPA estimate, maybe even slightly exceeding it. Individual results will vary.

How it compares

Compared to its competitors, the 2021 Ford Explorer RWD 3.0L is in the middle. The Toyota Highlander V6 FWD, for example, achieves a slightly better 24 MPG combined. The base Jeep Grand Cherokee with its V6 and RWD lands around 22 MPG combined. The Dodge Durango RWD with its V6 is often rated similarly to the Explorer.

These differences might seem small on paper, but they can add up over the lifespan of the vehicle. The choice often comes down to factors beyond fuel economy; space requirements, towing needs, and brand preference play significant roles. The Explorer provides that rear-wheel drive setup many SUV buyers want; all Ford fuel economy data shows this setup is becoming less common.

Tips to maximize efficiency

Minimize idling. The 3.0L engine consumes fuel even when stationary. Avoid letting the engine run unnecessarily, especially during brief stops. Turn off the engine if you anticipate being stopped for more than a minute or two.

Monitor tire pressure. Underinflated tires increase rolling resistance, directly impacting fuel economy. Check your tires regularly and maintain the recommended pressure listed on the doorjamb sticker. Correct tire pressure also improves handling and extends tire life.

Use cruise control on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, which can significantly improve fuel economy on long highway drives. Set the cruise control and let the vehicle manage the throttle for optimal efficiency.

Avoid aggressive driving. Rapid acceleration and hard braking consume significantly more fuel. Drive smoothly and anticipate traffic conditions to avoid unnecessary bursts of speed. A gentle driving style will not only improve fuel economy but also extend the life of your brakes and tires. A few slight changes will improve your EXPLORER MPG across all years.

Lighten the load. Extra weight increases fuel consumption. Remove any unnecessary items from the vehicle, especially heavy objects that are rarely used. Every pound counts, and reducing weight can positively impact fuel economy, particularly in city driving.
