17 MPG combined is a figure that will rightly scare off most SUV shoppers. But the 2017 Lincoln Navigator 4WD, with its 3.5L EcoBoost V6, isn’t aimed at “most” shoppers. This is a vehicle for those who prioritize space, towing capacity, and a certain kind of unapologetic American luxury above all else. Fuel economy is a consideration, sure, but it’s further down the list than you might find with other SUVs.

City and highway performance

The EPA estimates that the 2017 Navigator 4WD 3.5L will achieve 15 MPG in the city and 20 MPG on the highway. The city figure reflects the Navigator’s substantial weight and the stop-and-go nature of urban driving. The highway number is more respectable, and attainable, provided you resist the urge to constantly dip into the EcoBoost’s reserves of power. The six-speed automatic transmission, while reliable, lacks the gear count of more modern units, which contributes to less-than-stellar fuel economy. Remember, too, that these numbers are for the 4WD model; the 2WD Navigator is slightly more efficient. You can also compare NAVIGATOR MPG across all years to see how it stacks up against newer and older models.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2017 Lincoln Navigator 4WD 3.5L is $2,600. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. The EPA also uses national average fuel prices to calculate this cost, which means it can fluctuate depending on where you live and how much you drive. It’s a good benchmark, but plan for it to potentially be higher, especially if you frequently tow or haul heavy loads.

Real-world expectations

While the EPA estimates provide a baseline, your real-world fuel economy will likely vary. Factors such as driving style, traffic conditions, tire pressure, and even the weather can all impact your MPG. Aggressive acceleration, frequent hard braking, and prolonged idling will all decrease fuel efficiency. Towing, especially at the Navigator’s maximum capacity, will dramatically reduce your MPG. Ultimately, expect real-world numbers to hover around the EPA estimates, but don’t be surprised if they occasionally dip lower. If you’re especially conscientious behind the wheel you *might* see slightly higher numbers.

How it compares

Compared to its contemporaries, the 2017 Navigator’s fuel economy is, predictably, not its strong suit. A 2017 Cadillac Escalade 4WD, for example, also equipped with a powerful V8 engine, achieves roughly the same combined MPG. A more modern SUV like the 2020 Ford Expedition 4WD with its comparable EcoBoost engine and a 10-speed transmission, sees closer to 19-20 MPG combined. The Jeep Grand Wagoneer, a newer contender, also lands in this same ballpark of 17 MPG combined. These comparisons matter to the Navigator buyer because they highlight that while this Lincoln offers immense space and capability, other SUVs either match its fuel economy while offering more modern technology (Expedition), or offer similar capabilities with comparable running costs (Escalade). If efficiency is a major concern, alternatives definitely exist, but none quite capture the traditional Lincoln aesthetic.

Tips to maximize efficiency

While the Navigator might not be a fuel sipper, there are steps you can take to improve its efficiency. Regularly check and maintain proper tire pressure. Underinflated tires increase rolling resistance and significantly reduce MPG. Keep an eye on your tire pressure monitoring system and inflate your tires to the recommended pressure listed on the doorjamb sticker.

Avoid aggressive driving habits. Rapid acceleration and hard braking consume considerably more fuel. Instead, practice smooth acceleration and anticipate traffic flow to minimize unnecessary stops. Use cruise control on the highway to maintain a consistent speed and optimize fuel efficiency. A smooth and steady pace is your friend.

Minimize idling. Excessive idling wastes fuel and contributes to higher emissions. If you’re stopped for more than a minute, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, so the fuel savings from turning off the engine will outweigh the energy needed to restart it.

Reduce weight and improve aerodynamics. Remove any unnecessary cargo from your vehicle to reduce weight and improve fuel economy. And consider removing roof racks or cargo carriers when not in use, as they can increase aerodynamic drag and decrease MPG. Regular maintenance, like changing the oil and air filter, will also help ensure optimal engine performance and fuel efficiency. You can find all Lincoln fuel economy data on our site.
