15 MPG combined is what you can expect in a 2021 Nissan Armada 4WD with its 5.6L V8. Nobody buys an Armada for its fuel efficiency. They buy it for its large interior, its impressive towing capacity, and its undeniable presence. Fuel economy is simply the price you pay for these capabilities, and Armada buyers generally accept it.

City and highway performance

The EPA estimates the Armada gets 13 MPG in the city and 18 MPG on the highway. The city number reflects the demands of stop-and-go traffic on a large, heavy vehicle with a naturally aspirated V8. Each acceleration requires a significant amount of fuel. The highway number, while better, still isn’t great. The Armada’s aerodynamic profile, combined with the engine’s need to overcome wind resistance at higher speeds, means that 18 MPG is about as good as it gets. Expect this to drop further when towing.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Nissan Armada 4WD at $3,850. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes national average fuel prices. Remember that this is just an estimate. Your actual fuel costs could be higher or lower depending on your driving habits and where you live, as fuel prices vary significantly across the country.

Real-world expectations

While the EPA provides a benchmark, real-world fuel economy often differs. Aggressive driving, frequent short trips, or carrying heavy loads will all negatively impact fuel consumption. On the other hand, a driver with a light foot and a predominantly highway commute might see numbers closer to the EPA’s 18 MPG highway estimate. The Armada is not an efficient vehicle, so plan your budget accordingly. You can review ARMADA MPG across all years to see other model years and their consumption, too.

How it compares

The Armada’s fuel economy is similar to other large, V8-powered SUVs. The Chevrolet Tahoe 4WD with the 5.3L V8 gets 16 MPG combined, while the Ford Expedition 4×4 with its EcoBoost V6 manages a slightly better 19 MPG combined. The Toyota Sequoia, with its 5.7L V8, mirrors the Armada’s 15 MPG combined. Armada buyers often care more about price, features, and towing capacity than these differences. These all require trade offs, so understanding all Nissan fuel economy data can help.

Tips to maximize efficiency

Avoid aggressive acceleration. The Armada’s large engine responds to a heavy foot by gulping down fuel. Gentle acceleration, especially from a standstill, can improve fuel economy.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, found on the door jamb or in the owner’s manual. Adjust for temperature changes.

Reduce idling time. Idling wastes fuel, particularly in a large engine like the Armada’s V8. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently.

Optimize your driving route. Plan your trips to avoid congested areas and stop-and-go traffic. Highway driving, when possible, will mean better fuel economy than city driving.

Consider a less thirsty vehicle if fuel economy is important. If fuel economy is critical to your use case, then a smaller SUV or Crossover will use less gas.
