EPA Fuel Economy: 23 MPG Combined

The 2022 Toyota Highlander 3.5L V6 LE delivers an EPA-estimated 23 MPG combined, making it a solid fuel economy choice in the three-row SUV segment. With its powerful 3.5-liter V6 engine paired to an 8-speed automatic transmission, this midsize SUV balances performance and efficiency effectively. The combined rating represents a blend of city and highway driving, providing a realistic estimate for typical owners who encounter both road types during their commute and travel.

For a vehicle in the Highlander’s class—offering seating for up to eight passengers and substantial cargo space—the 23 MPG combined rating reflects Toyota’s engineering commitment to efficiency without compromising the power needed for family hauling and towing. This rating is particularly competitive for V6-powered three-row SUVs, where fuel economy can vary significantly depending on engine selection and transmission type. The 8-speed automatic transmission in this model helps optimize fuel consumption across various driving conditions by selecting the most efficient gear ratios.

City vs Highway Performance

The 2022 Highlander LE demonstrates a noticeable difference between city and highway driving conditions. The EPA rates this vehicle at 20 MPG in the city and 27 MPG on the highway—a 7 MPG difference that reflects real-world driving dynamics. City driving involves frequent acceleration, braking, and idling at traffic lights, which demands more fuel from the V6 engine. The 20 city MPG rating acknowledges these stop-and-go conditions while still maintaining respectable efficiency for a V6 SUV.

Highway driving tells a different story. At 27 MPG, the Highlander operates at steady speeds with minimal acceleration demands, allowing the 8-speed transmission to lock into higher gears that maximize fuel efficiency. If your driving consists primarily of highway miles, you’ll likely experience better overall fuel economy than the 23 combined rating. Conversely, drivers in urban environments with heavy traffic should expect fuel economy closer to the 20 city figure.

Annual Fuel Cost

Calculating annual fuel expenses provides practical insight into ownership costs. Using the EPA combined rating of 23 MPG, assuming 15,000 miles driven annually and a fuel price of $3.50 per gallon, here’s the breakdown:

Annual Fuel Cost Calculation:

• Annual miles: 15,000
• Divided by combined MPG: 15,000 ÷ 23 = 652 gallons per year
• Multiplied by fuel price: 652 × $3.50 = $2,282 annual fuel cost

This means the average owner of a 2022 Highlander LE can expect to spend approximately $2,282 annually on fuel at current prices. If your driving exceeds 15,000 miles yearly or fuel prices increase, costs will rise proportionally. Five-year fuel costs would total roughly $11,410, making fuel efficiency an important consideration in the total cost of ownership for this vehicle.

Real-World MPG Expectations

While EPA ratings provide standardized benchmarks, real-world fuel economy varies based on driving habits, vehicle maintenance, and conditions. Most owners of the 2022 Highlander LE report fuel economy within 1-2 MPG of the EPA combined estimate, though some achieve slightly better results. Aggressive acceleration, excessive idling, and driving with underinflated tires all reduce efficiency below EPA ratings.

To maximize your Highlander’s fuel economy, maintain proper tire pressure as specified in the owner’s manual, keep the engine properly maintained with regular tune-ups, and avoid carrying unnecessary cargo weight. Smooth acceleration and maintaining steady highway speeds also contribute to better fuel economy. Using cruise control on highways helps maintain consistent speeds that maximize efficiency. Additionally, warming up the engine briefly before driving and removing roof racks when not in use can improve MPG performance.

How It Compares

In the three-row SUV market, the 2022 Highlander LE’s 23 MPG combined rating compares favorably to competitors. The Kia Sorento with a similar V6 engine achieves approximately 22 MPG combined, while the Honda Pilot with its V6 engine rates at 22 MPG combined. The Mazda CX-9, another three-row option, delivers around 24 MPG combined with a turbocharged engine. The Highlander’s rating sits competitively in the middle, offering proven Toyota reliability alongside respectable fuel efficiency for buyers prioritizing family capacity and performance.

Tips to Maximize Efficiency

• Maintain Proper Tire Pressure: Underinflated tires increase rolling resistance and reduce fuel economy by up to 3%. Check pressure monthly using the specification on your driver’s door jamb.
• Use Synthetic Oil: The 3.5L V6 runs more efficiently with quality synthetic oil, reducing friction and improving MPG.
• Avoid Short Trips: Cold engines consume more fuel. Combine errands into single trips to allow the engine to reach optimal operating temperature.
• Monitor Your Air Filter: A clean air filter ensures optimal engine breathing and fuel combustion, supporting better efficiency.
• Drive Smoothly: Gradual acceleration and steady speeds improve fuel economy significantly compared to aggressive driving patterns.

Frequently Asked Questions

What is the fuel tank capacity of the 2022 Highlander LE? The 2022 Highlander LE features a 19.2-gallon fuel tank, which means at 23 MPG combined, you can expect a driving range of approximately 442 miles on a full tank.

Does the 3.5L V6 require premium gasoline? No, the 2022 Highlander LE 3.5L V6 operates on regular unleaded gasoline (87 octane), which helps keep fuel costs reasonable compared to vehicles requiring premium fuel.

Will towing reduce fuel economy? Yes, towing significantly impacts fuel economy. The Highlander LE can tow up to 5,000 pounds, but fuel economy decreases considerably when towing due to additional weight and engine strain. Expect reductions of 15-25% depending on trailer weight and driving conditions.

The 2022 Toyota Highlander 3.5L V6 LE offers practical fuel economy for a three-row family SUV, combining the power and space families need with reasonable fuel costs. Understanding your vehicle’s EPA ratings and implementing efficiency strategies helps you achieve the best possible fuel economy during ownership.
