23 MPG combined is a respectable figure for the 2020 Toyota Highlander AWD 3.5L 6-cyl. It’s a vehicle designed for family hauling and all-weather confidence, not outright fuel efficiency. Buyers seeking maximum MPG typically wouldn’t cross-shop the Highlander because its mission centers on reliability, practicality, and space above all else. However, for those prioritizing those core Toyota values and needing all-wheel drive, the Highlander’s fuel economy remains a key consideration.

City and highway performance

The EPA estimates 20 MPG in the city and 27 MPG on the highway for this specific Highlander configuration. The city figure reflects the stop-and-go nature of urban driving, where the Highlander’s weight and the engine’s need to overcome inertia impact fuel consumption. The highway MPG, however, shows the benefits of the eight-speed automatic transmission. It allows the engine to cruise at lower RPMs for improved efficiency on longer journeys. These numbers underscore that highway driving offers the best fuel economy in the Highlander, a logical expectation for a vehicle typically used on family road trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Toyota Highlander AWD 3.5L 6-cyl at $1,900. This figure is calculated based on 15,000 miles of driving per year, with 55% of those miles driven in the city and 45% on the highway. The calculation also relies on the national average fuel price at the time of the EPA’s testing. Individual fuel costs will vary depending on driving habits, local fuel prices, and the specific blend of fuel used. While $1,900 is a useful benchmark, always factor in your own driving patterns to estimate your personal expense.

Real-world expectations

While the EPA provides a standardized testing procedure, real-world MPG often varies. Aggressive driving, carrying heavy loads, and encountering headwinds can all negatively affect fuel economy. Conversely, gentle acceleration, consistent speeds, and optimal tire inflation can improve MPG beyond the EPA estimates. The Highlander’s all-wheel-drive system, while beneficial in inclement weather, adds weight and drivetrain friction, contributing to a slight reduction in fuel economy compared to the front-wheel-drive model. HIGHLANDER MPG across all years showcase the varying range this vehicle achieves, model year to model year.

How it compares

Compared to its competitors, the 2020 Toyota Highlander AWD 3.5L 6-cyl holds its own, but doesn’t necessarily lead the pack in fuel efficiency. The Honda Pilot AWD achieves a similar 22 MPG combined, while the Ford Explorer with its base 2.3L EcoBoost engine posts around 24 MPG combined in AWD configuration. The Kia Telluride AWD, another popular choice, mirrors the Highlander’s 23 MPG. The Nissan Pathfinder AWD typically falls slightly behind at around 22 MPG. Several hybrid options exist in this class, like the Highlander Hybrid itself, for significantly better mpg, but at a higher initial cost. The value-oriented buyer choosing the gasoline-powered Highlander needs to weigh fuel efficiency against purchase price, reliability reputation, and cargo capacity, where the Highlander consistently scores well.

Tips to maximize efficiency

The Highlander’s 3.5L V6 benefits from smooth and gradual acceleration. Avoid sudden bursts of speed, which force the engine to consume more fuel. Anticipate traffic flow and maintain a consistent speed whenever possible. The Highlander’s onboard driving coach, found in the gauge cluster, can assist you in optimizing your driving style.

Ensure your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which leads to reduced fuel economy. Regularly check your tire pressure, especially during temperature fluctuations.

Reduce excess weight in the vehicle. Carrying unnecessary cargo adds to the vehicle’s overall weight, requiring more engine power to move it. Remove any items you don’t need to haul around on a daily basis to improve fuel efficiency. Roof racks, in particular, create aerodynamic drag when unloaded.

Consider using the Highlander’s “Eco” mode, if equipped. This mode adjusts the engine and transmission settings to prioritize fuel efficiency. While it may slightly reduce throttle response, it can contribute to noticeable fuel savings, especially in city driving. Maintenance is also key to fuel economy. Keep an eye on all Toyota fuel economy data to better understand how these vehicles run most efficiently over an extended period of time.

Finally, staying on top of scheduled maintenance is crucial. Regular oil changes, air filter replacements, and spark plug maintenance ensure that the engine is running optimally. A well-maintained engine operates more efficiently and consumes less fuel.
