The 2019 Lincoln Nautilus AWD with the 2.7L V6 gets 21 MPG combined which is not going to win any awards for lower fuel costs, but it’s a perfectly reasonable figure for what this vehicle is: a comfortable, quiet, and well-appointed mid-size luxury SUV that prioritizes a smooth ride and effortless power over ultimate fuel sipping. The Nautilus buyer isn’t necessarily hyper-focused on economy, but they’re also not willing to accept abysmal gas mileage in exchange for a premium experience. They want something that feels luxurious without being ostentatious, and the Nautilus delivers.

City and highway performance

The EPA estimates for the 2019 Nautilus AWD with the 2.7L V6 break down to 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go driving, where the Nautilus’s weight and the engine’s need to overcome inertia take their toll. The highway number is more respectable, where the eight-speed automatic transmission can settle into a fuel-efficient gear and the engine can cruise comfortably. While 26 MPG is achievable on longer road trips, consistent lead-footed driving will certainly drop that number. Similarly, short trips around town with lots of cold starts will negatively impact the 19 MPG city figure.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific 2019 Lincoln Nautilus configuration at $2,100. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Keep in mind that this is just an estimate, and your actual fuel costs will vary depending on your driving habits, the type of driving you do (city versus highway), and the current price of gasoline in your area. Aggressive driving habits and consistent use of premium fuel (though not required, it’s sometimes preferred by owners) will significantly increase this annual cost.

Real-world expectations

While the EPA figures provide a good baseline, real-world fuel economy can vary based on individual driving styles, traffic conditions, and even the weather. Some owners report slightly better-than-EPA figures on long highway trips when driven conservatively. Others see lower numbers, especially in congested city environments. Pay attention to your driving habits and keep track of your MPG using the vehicle’s trip computer or a fuel tracking app to get a more accurate picture of your actual fuel costs.

How it compares

The Nautilus competes in a crowded segment of luxury SUVs, and its fuel economy performance is generally in line with its rivals, but there are greener options. For example, the Acura RDX with SH-AWD achieves a combined 23 MPG. The Lexus NX 300h hybrid delivers a significantly better 31 MPG combined, but at the expense of power and a different driving experience. The BMW X3 xDrive30i manages a combined 24 MPG, offering a sportier driving character. These differences matter to buyers. The Nautilus customer appreciates the smooth power delivery of the V6 and the focus on quiet comfort, even if it means slightly lower fuel economy compared to its more overtly sporty or hybrid competitors.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Nautilus’s 2.7L V6 provides ample power, so there’s rarely a need to floor the throttle. Gentle acceleration and anticipation of traffic flow will help keep the engine operating in its most efficient range.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressures regularly and inflate them to the recommended levels listed on the sticker inside the driver’s side doorjamb.

Minimize idling. Excessive idling wastes fuel. If you’re stopped for more than a minute, turn off the engine when it is safe to do so. The Nautilus does not have auto stop/start but eliminating needless idling is especially useful if you live in a city.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway drives. Avoid sudden bursts of acceleration or deceleration while using cruise control.

Consider fuel additives. Although not strictly necessary, some owners find that using a fuel additive designed to clean fuel injectors and improve combustion can help maintain optimal engine performance and fuel economy over the long term.
