19 MPG combined isn’t going to win any awards, but that’s what owners of the 2018 Lincoln Navigator 2WD get. They’ve likely accepted that. This isn’t a vehicle for hypermilers, it’s a rolling living room designed for comfort, space, and presence. The Navigator buyer wants a smooth ride, a cavernous interior, and the ability to tow a boat or trailer more than squeezing every last mile from a gallon of gasoline. They accept the fuel consumption because it’s what it costs to have that luxury and utility.

City and highway performance

The EPA estimates the 2018 Navigator 2WD at 16 MPG in the city and 23 MPG on the highway. That spread shows what the Navigator’s weight and size do to urban driving. Stop-and-go traffic and frequent acceleration strain the 3.5L turbocharged V6. On the open road, however, the Navigator settles into a more efficient cruise, using its ten-speed automatic transmission to keep the engine in its optimal power band. The highway figure is probably more relevant to the typical Navigator owner, who likely spends significant time on long road trips with family or clients.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2018 Lincoln Navigator 2WD at $2,300. This figure is based on driving 15,000 miles per year, using a blend of city and highway miles, and the national average fuel price at the time of calculation. Real-world fuel costs can change a lot depending on how someone drives, local fuel prices, and the specific conditions in which the vehicle is driven. Someone who mainly drives in congested city traffic will probably go over this estimate, while someone who mainly does highway cruising might come in under it.

Real-world expectations

Don’t expect to match the EPA numbers exactly. Expect real-world MPG for the 2018 Lincoln Navigator 2WD to be a bit lower, especially for those who frequently tow or haul heavy loads. Look for figures in the 14-18 MPG range in mixed driving. Hard acceleration and high speeds will lower fuel efficiency even more. Consider the EPA estimates a best-case scenario and keep your expectations in check. Check owner forums and fuel tracking apps to get a better idea of what other drivers are getting in similar conditions. You can also compare all Lincoln fuel economy data to get fuel efficiency insights on other models.

How it compares

The Navigator is in a segment where fuel economy isn’t the main thing people care about, but it’s still good to know how it compares. The Cadillac Escalade, another full-size luxury SUV, gets about the same 17 MPG combined in its two-wheel-drive configuration. The Infiniti QX80, known for its reliable engine, also gets around 16 MPG combined. The Mercedes-Benz GLS450 gets slightly better efficiency at 20 MPG combined, but it’s more refined than the Navigator’s American swagger.

Tips to maximize efficiency

Avoid hard acceleration. The Navigator’s turbocharged engine gives lots of power, but stomping on the gas pedal will really hurt fuel consumption. Accelerate slowly and steadily so the engine can operate more efficiently.

Keep tires properly inflated. Tires that don’t have enough air increase rolling resistance, which makes the engine work harder and burn more fuel. Check your tire pressure often and inflate them to the recommended level, which can be found on the driver’s side doorjamb.

Reduce extra weight. Carrying unnecessary cargo makes the vehicle heavier and negatively affects fuel economy. Take out anything from the vehicle that isn’t needed, especially when driving around town.

Use cruise control on the highway. Maintaining a consistent speed helps save fuel. Using cruise control on long highway drives makes speed more consistent for smoother, more efficient operation.

Be careful not to idle too much. Idling wastes fuel and pollutes. If you’re stopped for more than a minute or two, turn off the engine. The Navigator’s comfortable cabin can make you want to leave the engine running, but it’s expensive.
