23 MPG combined is an acceptable figure for the 2017 Toyota Highlander LE/XLE/SE/LTD 3.5L 6-cyl, a mid-size three-row SUV. It prioritizes space, reliability, and family-friendly features over outright fuel efficiency. This isn’t a hybrid or a compact crossover; it’s a practical vehicle designed to haul kids to soccer practice, manage grocery runs, and tackle long road trips. Buyers choose the Highlander for its reputation and versatility, understanding that great MPG isn’t its primary strength.

City and highway performance

The EPA estimates the 2017 Highlander 3.5L V6 at 21 MPG in the city and 27 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, putting the engine under more load and reducing efficiency. The highway MPG demonstrates the engine’s ability to cruise efficiently at consistent speeds. The eight-speed automatic transmission (S8) plays an important role here, allowing the engine to operate at lower RPMs on the open road and optimizing fuel consumption.

The transmission’s programming adapts to driving style, favoring fuel economy when possible, yet readily downshifting when more power is needed for passing or climbing hills.

Annual fuel cost

The EPA calculates the estimated annual fuel cost for the 2017 Toyota Highlander LE/XLE/SE/LTD 3.5L 6-cyl to be $1,900. This figure is based on driving 15,000 miles per year, with a specified percentage of those miles driven in both city and highway conditions. The calculation also uses the national average fuel price at the time of the EPA’s testing, meaning that your actual fuel costs may vary depending on your driving habits and prevailing gas prices in your area. It’s a useful benchmark for comparing the Highlander’s running costs to other vehicles, but individual experiences will differ.

Real-world expectations

The EPA estimates provide a standardized baseline, but real-world fuel economy can vary considerably depending on several factors. Aggressive driving, frequent short trips, carrying heavy loads, and even tire pressure can all impact MPG. Highlander owners who prioritize smooth acceleration, anticipate traffic flow, and maintain their vehicle diligently are more likely to achieve figures closer to the EPA estimates.

Conversely, those who frequently tow, drive in mountainous terrain, or have a lead foot may find their fuel economy slightly lower than advertised. Checking owner forums and fuel tracking apps can provide a more realistic picture of what to expect in everyday driving conditions.

How it compares

The 2017 Highlander’s fuel economy stacks up differently depending on the competition. A comparable 2017 Honda Pilot with its 3.5L V6 is rated at 22 MPG combined, essentially mirroring the Highlander. A 2017 Ford Explorer with the standard 3.5L V6 lands in a similar range, but slightly lower, at 19 MPG combined. The 2017 Nissan Pathfinder is rated at 22 MPG when equipped with front-wheel drive. These discrepancies, while seemingly minor, can influence buyers weighing purchase decisions. For example, families that make frequent long trips might value the Highlander’s slight highway MPG edge over the Pilot.

Potential buyers should also check out all all Toyota fuel economy data to consider other Toyota options and compare the HIGHLANDER MPG across all years to find out which model may be right for them.

Tips to maximize efficiency

Gentle acceleration and consistent speeds are key to maximizing fuel efficiency in the 2017 Highlander. Avoid sudden bursts of speed and try to maintain a steady pace, especially on the highway. The Highlander’s V6 engine delivers ample power, but using it wisely will translate to significant fuel savings over time.

Regular maintenance is critical for optimal fuel economy. Ensure that your Highlander’s tires are properly inflated, as under-inflated tires increase rolling resistance and reduce MPG. Keeping up with scheduled oil changes and air filter replacements helps the engine run efficiently.

Avoid carrying unnecessary weight in your Highlander. Every extra pound decreases fuel economy. Remove items from the cargo area that you don’t need on a regular basis, and consider lighter alternatives when purchasing roof racks or cargo carriers.

Use cruise control on the highway to maintain a constant speed and minimize unnecessary acceleration and deceleration. Cruise control helps to optimize fuel consumption on long drives by preventing you from inadvertently speeding up or slowing down.
