The 2020 Nissan Armada 4WD, equipped with a 5.6L V8 engine, has an EPA-estimated fuel economy of 15 MPG combined. This places it among the least fuel-efficient SUVs, and most buyers are likely aware of this. The Armada prioritizes transporting families, towing, and navigating challenging conditions with V8 power and truck-based reliability over fuel efficiency.

City and highway performance

The EPA further breaks down the Armada’s fuel consumption, estimating 13 MPG in the city and 18 MPG on the highway. The city MPG reflects the impact of the Armada’s approximately 6,000-pound weight and frequent stops, which require considerable effort to overcome inertia. The highway MPG is more reasonable when cruising. Its automatic (S7) transmission likely contributes to this, especially with cruise control on flat roads. This is a full-size SUV designed to comfortably carry up to eight passengers and their luggage, so fuel efficiency is secondary to capability and spaciousness.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Nissan Armada 4WD at $2,900. This is calculated based on 15,000 miles of driving per year, with 55% in the city and 45% on the highway, using average national fuel prices at the time of calculation. Your actual fuel costs may vary depending on driving habits, fuel type, and gas price fluctuations. For Armada owners, this cost is often part of owning a large, capable vehicle.

Real-world expectations

While the EPA provides a standard, your actual fuel economy will likely vary. Driving style, terrain, weather, and cargo weight all affect fuel consumption. Aggressive acceleration, frequent braking, and hilly terrain will generally decrease fuel economy. Smooth driving, steady speeds on flat roads, and minimized idling can help improve fuel efficiency. Don’t be surprised by figures slightly below the EPA estimates in mixed driving, especially when towing or carrying heavy loads. Some owners of similar vehicles report that highway MPG can exceed the EPA estimate with reasonable speed limits and low headwinds.

How it compares

The Armada’s fuel economy ranks it near the bottom of the full-size SUV class. A 2020 Chevrolet Tahoe 4WD with the 5.3L V8, for instance, gets an EPA-estimated 18 MPG combined. A Ford Expedition 4×4, powered by a 3.5L EcoBoost V6, achieves around 19 MPG combined. A Toyota Sequoia 4WD, another V8-powered option, mirrors the Armada’s 15 MPG combined. The main tradeoff is between fuel economy and towing capacity. While some competitors have slightly better fuel economy, they might not offer the Armada’s V8 power or its strong, truck-based build. Buyers must weigh the importance of fuel economy against their capability needs. Browsing ARMADA MPG across all years can provide a broader perspective on this model’s trend.

Tips to Maximize Efficiency

Even with its V8 engine, there are ways to improve your Armada’s fuel economy. Avoid aggressive acceleration and hard braking. Gentle inputs minimize wasted energy, preventing unnecessary engine revving. This is useful in city driving, where anticipating traffic can reduce sudden stops.

Tire pressure is important for fuel efficiency. Keep tires inflated to the recommended pressure, found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder. Check tire pressure regularly, especially with temperature changes.

Reduce idling time when possible. Modern engines consume fuel while idling, particularly the Armada’s. If you’ll be stopped for more than a minute, turn off the engine. This can save fuel, especially in heavy traffic.

Adjust your driving to anticipate lane changes and traffic lights. Maintaining a steady speed and avoiding unnecessary braking will improve fuel economy. Use cruise control, but only on flat roads, because its benefits decrease on uphill grades.

Be aware of extra weight. Remove unnecessary cargo from your Armada, as extra weight increases fuel consumption. Avoid leaving heavy items in the vehicle unless needed. This is important for long trips; pack efficiently and leave behind non-essential items. You can always research all Nissan fuel economy data if you want context on other economical vehicles from the brand.
