16 MPG combined isn’t going to win any fuel economy awards, but it succinctly defines the 2021 Nissan Armada 2WD 5.6L 8-cyl as a traditional, body-on-frame SUV focused on capability and space above all else. This isn’t a vehicle for the hypermiler; it’s for the family that needs to tow a boat, haul a crew, and isn’t overly concerned with trips to the gas station relative to the Armada’s core strengths. It’s a niche, but a fiercely loyal one.

City and highway performance

The EPA estimates the Armada at 14 MPG in the city and 19 MPG on the highway. These numbers reflect the realities of moving a vehicle weighing nearly 6,000 pounds, powered by a naturally aspirated 5.6L V8 engine and a seven-speed automatic transmission. Stop-and-go traffic consistently drags down fuel economy, highlighting the engine’s need to overcome inertia repeatedly. Open highway driving provides a slight respite, but even then, aerodynamic drag and the sheer mass of the Armada limit any significant fuel savings. Understanding this tradeoff is key for anyone considering this SUV.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,600 for the 2021 Nissan Armada 2WD 5.6L 8-cyl. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. The real cost may vary based on driving habits, local fuel prices, and the specific grade of gasoline used. However, this $3,600 figure offers a clear benchmark for prospective buyers to factor into their ownership costs.

Real-world expectations

While the EPA provides standardized testing figures, expect some variance in real-world driving. Aggressive acceleration, frequent towing, or consistent use of four-wheel drive (in models so equipped) will lower MPG. Gentle driving habits and primarily highway use might allow drivers to approach, or even slightly exceed, the EPA’s estimates. Tire pressure maintenance and regular servicing also play an important role in achieving optimal fuel efficiency. Keep in mind that the Armada’s strong reliable capability comes at the expense of fuel economy.

How it compares

Compared to other large SUVs, the 2021 Nissan Armada’s fuel economy lands squarely in line with its direct competitors. The Chevrolet Tahoe 5.3L V8 2WD is rated at 16 MPG combined (15 city/20 highway), while the Ford Expedition 2WD with the EcoBoost V6 achieves 19 MPG combined (17 city/23 highway). The Toyota Sequoia with its 5.7L V8 manages only 15 MPG combined (13 city/17 highway). The Grand Wagoneer, with it’s thirsty standard engine, achieves a paltry 15 MPG combined. These numbers underscore a simple truth: moving this much mass requires considerable energy. For those seeking better fuel economy in a three-row SUV, options like the Toyota Highlander Hybrid (36 MPG combined) exist, but they sacrifice the towing capacity and ruggedness that Armada buyers prioritize.

Tips to maximize efficiency

Avoid aggressive acceleration. The Armada’s V8 engine has plenty of power, but using it unnecessarily burns fuel. Gradual acceleration allows the engine to operate more efficiently, reducing consumption without significantly impacting your journey time.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended levels found on the doorjamb sticker. This simple task can noticeably improve your MPG.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute or two, turn off the engine. Modern engine start/stop systems in other vehicles make this smooth, but in the Armada, old-fashioned key-off is the way to save fuel.

Plan your routes strategically. Avoiding congested areas and stop-and-go traffic reduces the amount of idling and hard acceleration, both of which negatively impact fuel economy. Using navigation apps to find the most efficient routes can save both time and fuel. Comparing ARMADA MPG across all years is something to also consider when searching for the perfect vehicle.
