18 MPG combined is the price of admission to the world of full-size luxury SUVs, especially those stretched to offer limo-like legroom in all three rows. The 2020 Lincoln Navigator L 2WD 3.5L isn’t trying to be a fuel sipper; it’s built for hauling families and cargo in comfort, and its fuel consumption reflects that priority.

City and highway performance

The Navigator L’s fuel economy breaks down to an EPA-estimated 16 MPG in the city and 21 MPG on the highway. The “L” designation means this is the extended-wheelbase version, adding overall length and weight. Its turbocharged 3.5-liter V6 requires more fuel to move this larger package than a shorter, lighter SUV would. The 10-speed automatic transmission optimizes efficiency, but physics dictate the outcome. Highway cruising, with its consistent speeds, allows the engine to settle into a more efficient range, explaining the higher MPG figure. City driving, with its constant stop-and-go, forces the engine to work harder and burn more fuel.

Annual fuel cost

The EPA estimates that the 2020 Lincoln Navigator L 2WD 3.5L will cost $2,450 per year in fuel. This figure is based on driving 15,000 miles annually, with 55% of those miles driven in the city and 45% on the highway. The calculation also assumes national average fuel prices. Keep in mind your actual fuel costs will vary depending on your driving habits and local fuel prices. This $2,450 figure provides a benchmark for comparing against other vehicles, but a driver who accelerates quickly in a city with high fuel taxes will likely spend significantly more.

Real-world expectations

While the EPA estimates provide a comparison, real-world fuel economy often differs, and the Navigator L is no exception. Factors such as driving style, traffic conditions, and even tire pressure can impact how many miles you get per gallon. Owners who frequently tow or carry heavy loads will see a further decrease in fuel economy.

Conversely, drivers who accelerate smoothly and maintain consistent speeds on the highway may find themselves closer to, or even slightly exceeding, the EPA estimates. Regular maintenance, including timely oil changes and air filter replacements, also plays a role in maximizing fuel efficiency.

How it compares

The Navigator L’s fuel economy puts it in line with its competitors. The Cadillac Escalade ESV, another extended-wheelbase luxury SUV, achieves similar figures, around 14 MPG city and 20 MPG highway with its standard 6.2-liter V8. The Infiniti QX80, while offering a slightly different driving experience, also hovers in the same fuel economy range. Drivers considering the Navigator L probably aren’t prioritizing fuel efficiency above all else; they are seeking maximum space, luxury, and towing capability. Checking NAVIGATOR MPG across all years can highlight minor differences stemming from various engine and drivetrain configurations.

Tips to maximize efficiency

While the Navigator L isn’t designed for exceptional fuel economy, there are steps owners can take to improve their MPG. Avoid aggressive acceleration and braking. The Navigator L packs a punch with its twin-turbo V6, but each burst of speed demands extra fuel. Anticipating traffic and maintaining a smooth, steady pace will minimize fuel consumption.

Proper tire inflation plays a role. Under-inflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, which can be found on a sticker inside the driver’s side doorjamb.

Minimize idling. Letting the engine run while parked or waiting consumes fuel without covering any distance. If you anticipate being stationary for more than a minute, turn off the engine. Many modern vehicles, including some Navigator models, offer auto start-stop functionality to automatically shut off the engine at stoplights.

Consider using cruise control on the highway. Maintaining a constant speed not only reduces driver fatigue but also optimizes engine efficiency. Cruise control helps prevent unintentional acceleration and deceleration, contributing to more consistent fuel consumption. However, be mindful of using cruise control in hilly terrain, as it can sometimes lead to excessive downshifting and reduced fuel economy.

Regular maintenance is critical for fuel efficiency. A well-maintained engine runs more smoothly and efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. Neglecting these tasks can lead to reduced performance and decreased fuel economy. Review all Lincoln fuel economy data to determine if there are more efficient models within the Lincoln lineup better suited to your needs.
