16 MPG combined is what owners of the 2017 Lincoln Navigator L 4WD with the 3.5L EcoBoost engine actually get. To be clear, nobody buys this extended-length, four-wheel-drive luxury vehicle expecting Prius-like efficiency. This truck is built for hauling families, gear, and often, trailers. Fuel economy is a secondary consideration, a necessary evil accepted in exchange for unmatched space and capability.
City and highway performance
The EPA estimates that the 2017 Navigator L 4WD will achieve 15 MPG in the city and 19 MPG on the highway. These figures reflect the demands placed on the 3.5L EcoBoost V6 and the six-speed automatic transmission while battling stop-and-go traffic and wind resistance. The city figure reflects the Navigator’s significant curb weight, requiring substantial energy to accelerate from a standstill. The highway mileage, while still low by modern standards, highlights the engine’s ability to cruise efficiently at consistent speeds, given its forced-induction technology and relatively tall gearing. Understanding that these EPA figures are attained under ideal conditions will help owners calibrate their own expectations.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2017 Lincoln Navigator L 4WD to be $2,750. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. That’s a substantial amount of money and represents a significant ongoing expense for Navigator owners. Buyers should consider this cost carefully during their purchasing decision, particularly if their annual mileage deviates significantly from the EPA’s estimate. For example, those who frequently tow or drive primarily in urban environments can expect to spend considerably more than the advertised $2,750.
Real-world expectations
Real-world fuel economy for the 2017 Navigator L 4WD often falls slightly below the EPA estimates. Owners report averaging closer to 13-14 MPG in mixed driving conditions, especially in areas with hilly terrain or frequent traffic congestion. Towing significantly impacts fuel efficiency, with numbers dropping to the single digits when hauling heavy loads. The Navigator’s sheer size and weight, combined with the inherently thirsty nature of a turbocharged engine under load, contribute to these lower-than-expected figures. It’s vital for prospective buyers to carefully consider their own driving habits and usage patterns when evaluating the true cost of ownership.
How it compares
Compared to its competitors, the 2017 Lincoln Navigator L 4WD lands squarely in the middle of the pack in terms of fuel economy. The Cadillac Escalade ESV 4WD, with its 6.2L V8, achieves a similar 15 MPG combined. The Infiniti QX80 4WD, another contender in this segment, posts EPA ratings of 15 MPG combined with its naturally aspirated 5.6L V8. Newer designs, like the redesigned 2018+ Navigator, saw a noticeable jump in efficiency, offering figures closer to 19 MPG combined. This difference is important for buyers who prioritize fuel economy while still requiring the space and capability of a large SUV. You can find NAVIGATOR MPG across all years on our website.
Tips to maximize efficiency
Aggressive acceleration and hard braking significantly reduce fuel economy. The Navigator L is a heavy vehicle, and requiring the engine to repeatedly overcome its inertia consumes a lot of fuel. Smooth, gradual acceleration and anticipation of traffic flow are key to maximizing mileage.
Regular maintenance, including timely oil changes and air filter replacements, is critical for optimal engine performance. A neglected engine simply cannot operate as efficiently as one that’s properly maintained. Ensuring your tires are properly inflated also helps to reduce rolling resistance, leading to improved fuel economy.
Avoid idling for extended periods. The Navigator’s large engine consumes a surprising amount of fuel even when stationary. If you anticipate being stopped for more than a minute, it’s best to turn off the engine. This simple habit can noticeably improve your fuel economy over time.
Minimize your cargo and towing when possible. Extra weight puts additional strain on the engine, reducing fuel efficiency, especially during city driving. Only haul what is absolutely necessary for each trip. Be sure to check all Lincoln fuel economy data too.
Use cruise control on the highway. Maintaining a constant speed helps the engine operate at its most efficient point. However, use caution when driving in hilly conditions; frequent shifting can negate the benefit of cruise control. If significant elevation changes are present, it may be more efficient to manage the throttle manually.
