14 MPG combined. Let’s be blunt: that’s not a number that will win over anyone looking for less gas. The 2015 Toyota Sequoia 4WD 5.7L isn’t about sipping fuel; it’s about hauling families, towing boats, and tackling terrain that would leave lesser SUVs stranded. This truck wasn’t designed for short trips around town. It’s built for those who need serious capability and are willing to pay the price at the pump.

City and highway performance

The EPA estimates the 2015 Sequoia at 13 MPG in the city and 17 MPG on the highway. These figures reflect the realities of a large, body-on-frame SUV powered by a naturally aspirated 5.7L V8 engine. The city number is influenced by the vehicle’s considerable weight (around 6,000 pounds), stop-and-go traffic, and the engine’s need to work harder to get the Sequoia moving from a standstill.

The highway figure, while slightly better, still reflects the aerodynamic challenges of a large, boxy vehicle pushing a lot of air at higher speeds. A six-speed automatic transmission helps make the most of the engine’s considerable torque, but it can only do so much to mitigate the fundamental laws of physics.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Toyota Sequoia 4WD 5.7L is $3,150. This calculation is based on driving 15,000 miles per year and using national average fuel prices. This is a significant figure, one that potential buyers must seriously consider.

If you frequently drive more than 15,000 miles per year or gas prices in your area are higher than the national average, you can expect to spend even more. Owners of the Sequoia know going in that they are signing on for fuel costs significantly above average. They aren’t looking at all Toyota fuel economy data and hoping for Prius-like numbers.

Real-world expectations

While the EPA provides a standardized test, many owners find the real-world fuel economy of the 2015 Sequoia to be even lower. Factors such as driving habits, load, and terrain can all significantly impact fuel consumption. Towing, especially heavy loads, will dramatically drop the MPG. Aggressive acceleration and frequent braking in city driving will also take a toll.

Owners who primarily use their Sequoia for highway cruising and maintain consistent speeds may see figures closer to the EPA estimate, but achieving significantly better MPG is unlikely.

How it compares

The 2015 Sequoia’s fuel economy isn’t exactly stellar compared to its competitors. The Ford Expedition, for example, with its 3.5L EcoBoost V6, could achieve up to 16 MPG combined in 4WD configuration. The Chevrolet Tahoe, with its 5.3L V8, landed in the same ballpark as the Sequoia, rated at 16 MPG combined in 4WD trim, but with cylinder deactivation technology aimed at improving efficiency.

The Nissan Armada, another body-on-frame SUV, offered similar fuel economy to the Sequoia, around 14 MPG combined. Buyers considering the SEQUOIA MPG across all years are often cross-shopping these vehicles, but they will also be prioritizing factors beyond fuel economy, like space, towing capacity, and reliability.

Tips to maximize efficiency

While you can’t fundamentally alter the Sequoia’s thirst for fuel, there are a few things you can do to maximize efficiency. First, practice smooth acceleration and avoid unnecessary braking. The Sequoia’s considerable weight requires a gentler touch on the pedals to maintain momentum and avoid wasting fuel. Anticipate traffic flow and coast whenever possible.

Check your tire pressure regularly and ensure they are inflated to the recommended level. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. A simple tire pressure check can make a small but noticeable difference over time. Use the recommended grade of gasoline as specified in the owner’s manual. Using a lower octane fuel can negatively impact performance and fuel economy.

Keep up with regular maintenance, including oil changes and air filter replacements. A clean air filter ensures the engine receives adequate airflow for optimal combustion, and fresh oil reduces friction, allowing the engine to run more efficiently. A well-maintained engine is a more efficient engine.

Minimize unnecessary weight. Carrying extra cargo adds to the vehicle’s overall weight, increasing fuel consumption. Remove any items you don’t need to carry to lighten the load and improve MPG. Also, aerodynamic drag increases with speed; so, avoid roof racks or carriers if you don’t need them.
