The official EPA fuel economy rating for the 2018 Toyota Highlander AWD with the 3.5L V6 is 22 MPG combined. While not class-leading, it’s an acceptable trade-off for the Highlander’s reliability, spaciousness, and all-weather capability. This is a vehicle for families who prioritize dependability and practicality over fuel savings, knowing they’re buying a well-engineered machine that will likely last for many years.

City and highway performance

The EPA estimates 19 MPG in the city and 26 MPG on the highway for this specific Highlander configuration. The city figure reflects the added weight and friction inherent to an all-wheel-drive system, along with urban driving’s stop-and-go nature. The 26 MPG highway rating points to a well-optimized powertrain that performs efficiently during steady-state cruising. The eight-speed automatic transmission also helps, keeping the engine at optimal RPMs for fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Toyota Highlander AWD 3.5L 6-cyl at $2,000. This figure is based on driving 15,000 miles per year, using national average fuel prices. Individual spending will vary depending on driving habits and local gas prices, but $2,000 provides a benchmark for comparing the Highlander’s fuel costs against other vehicles in its class, or even against all Toyota fuel economy data. Consider your own driving patterns and fuel costs to better estimate your personal expenses.

Real-world expectations

The EPA estimates provide a standardized baseline, but real-world MPG often varies. A number of Highlander owners have reported figures close to the EPA ratings. Responsible driving habits and consistent maintenance can yield fuel economy numbers on par with the official estimates. Aggressive acceleration, frequent short trips, and neglected maintenance will certainly reduce fuel economy below the stated figures. The all-wheel-drive system will also slightly reduce fuel economy; if constant traction isn’t needed, drivers might see slightly improved numbers in an equivalent front-wheel-drive model from a different year.

How it compares

The 2018 Highlander’s fuel economy is competitive within its segment. For example, the 2018 Honda Pilot AWD delivers roughly the same 22 MPG combined. The Ford Explorer with its base V6 engine offers similar figures. Some competitors, like the Nissan Pathfinder (around 20 MPG combined with AWD), fall slightly behind the Highlander, while others like the Mazda CX-9 (around 23 MPG combined) might eke out a small advantage. The differences can be negligible in real-world driving, making overall vehicle characteristics a more significant factor in the buying decision.

Tips to maximize efficiency

Gentle acceleration is an easy way to improve fuel economy. Avoid pressing hard on the gas pedal, especially when starting from a stop; the Highlander’s V6 has plenty of torque. Smooth, gradual acceleration allows the engine to operate more efficiently.

Proper tire inflation is important for fuel economy. Check your tires regularly and ensure they are inflated to the recommended pressure, which is usually found on a sticker inside the driver’s side doorjamb. Under-inflated tires create more rolling resistance, forcing the engine to work harder.

Minimize aerodynamic drag by removing any unnecessary cargo carriers or roof racks when you’re not using them. These accessories increase wind resistance, especially at highway speeds, significantly impacting fuel economy. Keeping the vehicle clean and waxed can also slightly reduce drag.

Reduce idling. Avoid letting the engine idle for extended periods, especially in cold weather. Modern engines warm up relatively quickly even while driving, and idling consumes fuel without moving you forward. If you’re waiting for more than a minute or two, it’s more efficient to turn off the engine.
