A combined 17 MPG defines the 2021 Lincoln Navigator 4WD 3.5L. This is a low number, but it reflects the reality of driving a three-ton, truck-based luxury SUV with immense towing capacity and significant road presence. Navigator buyers aren’t seeking Prius-like efficiency; they need space, comfort, and capability, and they’re willing to pay for it at the pump.

City and highway performance

The numbers break down to 16 MPG in the city and 20 MPG on the highway. That city figure results from the Navigator’s weight and urban driving’s stop-and-go nature. The turbocharged 3.5-liter V6, while powerful, requires fuel to move that much mass from a standstill. The 20 MPG highway figure is more respectable, highlighting the engine’s ability to cruise efficiently once it’s up to speed and the ten-speed automatic transmission’s role in keeping the engine in its optimal power band. Long road trips will involve more frequent fuel stops than in a smaller, lighter vehicle.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Lincoln Navigator 4WD at $2,600. This figure is based on driving 15,000 miles per year with fuel prices based on national averages. It’s a significant expense that Navigator owners need to consider in their overall cost of ownership. Fluctuations in gas prices will affect this number, but it provides a baseline for budgeting. Smart shoppers should review all Lincoln fuel economy data before deciding if the Navigator fits their financial needs.

Real-world expectations

While the EPA figures provide a benchmark, real-world MPG can vary based on driving style, load, and terrain. Aggressive acceleration, frequent towing, and mountainous routes will negatively impact fuel economy. Gentle driving, consistent highway speeds, and minimizing cargo weight can help you approach the EPA estimates. Remember that the Navigator’s size and weight will always be the primary factors determining its fuel consumption.

How it compares

The Navigator’s fuel economy places it within its competitive set. The Cadillac Escalade, with its 6.2-liter V8, achieves 16 MPG combined in 4WD. The Infiniti QX80 posts similar numbers to the Navigator, residing in the 16-17 MPG range. The Mercedes-Benz GLS 450, with its turbocharged inline-six and mild hybrid system, manages 20 MPG combined, but it lacks the Navigator’s maximum towing capability. Understanding NAVIGATOR MPG across all years compared to the competition is vital.

Tips to maximize efficiency

Maintain proper tire inflation. The correct tire pressure, as indicated on the door jamb sticker, optimizes rolling resistance, which can improve fuel economy over time. Regularly check and adjust tire pressure, especially with temperature changes, to ensure you’re not losing efficiency.

Avoid aggressive driving habits. Hard acceleration and braking are fuel-economy killers, especially in a heavy SUV like the Navigator. Practice smooth acceleration and anticipate stops to minimize wasted energy. Using adaptive cruise control on the highway can help maintain consistent speeds and optimize fuel consumption.

Minimize idling. Letting the engine idle for extended periods burns fuel. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and reliably, so you won’t be causing any undue wear and tear.

Lighten the load. Carrying unnecessary weight in the vehicle reduces fuel economy. Remove items from the cargo area that you don’t need regularly. This is especially important if you frequently use the Navigator for passenger transport but rarely need the maximum cargo capacity.

Use the correct fuel grade. The Navigator’s engine is designed to run on premium gasoline for performance and efficiency. Using lower-grade fuel can decrease performance and potentially damage the engine, costing you more in the long run.
