20 MPG combined is a reasonable, if unexceptional, figure for the 2021 Ford F150 4WD with the 3.3L V6. It’s the price of entry for those who need a work truck with four-wheel drive capability. No one is buying this configuration of F150 for its fuel efficiency; they’re buying it for reliability, for a dependable engine and drivetrain in a package that’s proven and relatively affordable. This is the fleet truck special, the choice of contractors and small business owners who prioritize a reliable workhorse over flashy features or groundbreaking fuel savings.

City and highway performance

The EPA estimates peg the 2021 Ford F150 4WD FFV 3.3L V6 at 19 MPG in the city and 22 MPG on the highway. These numbers reflect the engine’s tuning and the 10-speed automatic transmission’s programming. The city figure is particularly relevant for those who spend a significant amount of time navigating stop-and-go traffic on job sites or urban environments. The highway MPG is achievable for those longer hauls between projects, so long as you are mindful of your speed.

Annual fuel cost

The EPA estimates the annual fuel cost for this particular F150 configuration at exactly $2,200. This figure is based on driving 15,000 miles per year and using national average fuel prices current at the time of testing. Your actual fuel costs will vary depending on where you live, how you drive, and how much you drive. If you use your F150 primarily for short trips around town with frequent heavy loads, you’ll likely exceed this estimate. Conversely, if you are doing mostly long highway miles unloaded, you may beat the $2,200 estimate.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG for the 2021 Ford F150 4WD FFV 3.3L V6 will fluctuate considerably. Factors like driving style, load weight, tire pressure, and even weather conditions will all play a role. Expect lower MPG when towing or hauling heavy loads, as the engine works harder to maintain speed. Conversely, gentle acceleration and consistent highway speeds can help you approach or even surpass the EPA estimates. Don’t focus on achieving the sticker number every single trip; think of it as a guideline. See F150 MPG across all years for more data.

How it compares

Compared to other full-size trucks with similar capabilities, the 2021 F150’s fuel economy is competitive within its class. For example, a similar configuration of the 2021 Chevrolet Silverado 1500 with the 4.3L V6 and four-wheel drive achieves around 18 MPG combined. The Ram 1500 Classic with the 3.6L V6 and 4×4 is similarly rated around 19 MPG combined. The Toyota Tundra, known for its reliable construction but less so for exceptional fuel economy, delivers around 14 MPG combined with its V8 engine and 4WD. The F150’s figures are acceptable, but the key is powertrain dependability more than class-leading fuel economy. If fuel economy were the top priority, then buyers would focus on Ford’s hybrid and EcoBoost engine options, which offer significant MPG improvements. See all Ford fuel economy data here.

Tips to maximize efficiency

Gentle acceleration is crucial for maximizing fuel economy. Avoid aggressive starts and stops, as these actions force the engine to consume more fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Proper tire inflation is essential. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the manufacturer’s recommended level, found on the sticker inside the driver’s side door frame.

Reduce unnecessary weight. Hauling extra cargo adds strain to the engine, decreasing MPG. Remove any unnecessary items from the bed of the truck or the cabin to improve efficiency.

Minimize idling. If you are stopped for more than 30 seconds, turn off the engine. Idling consumes fuel without moving the vehicle. This is particularly relevant on construction sites or during deliveries.

Use cruise control on the highway. Engaging cruise control helps maintain a consistent speed, which can optimize fuel economy. Be mindful of terrain changes and adjust speed as needed to avoid excessive downshifting.
