2023 Toyota Highlander Hybrid AWD: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2023 Toyota Highlander Hybrid AWD. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Fuel economy at a glance

These are the EPA's official ratings for the 2023 Toyota Highlander Hybrid AWD. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2023 Toyota Highlander Hybrid AWD compares

The 2023 Toyota Highlander Hybrid AWD returns 35 combined MPG. Cars in the Standard Sport Utility Vehicle 4WD class for the same model year average 30.4 MPG, which puts this car ahead of the class average by about 15%.

The most efficient car in the Standard Sport Utility Vehicle 4WD class for the 2023 model year is the Tesla Model X at 102 MPG. The bar chart below puts the Toyota Highlander Hybrid AWD alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2023 model year (across all classes) returns 33.7 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2023 model year is on its own page.

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 428.6 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Toyota Highlander Hybrid AWD

The EPA has rated the Toyota Highlander Hybrid AWD across 13 model years, from 2014 Toyota Highlander Hybrid AWD through 2026 Toyota Highlander Hybrid AWD. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.

The 2014 Toyota Highlander Hybrid AWD returned 28 MPG. The most recent 2026 Toyota Highlander Hybrid AWD returns 35 MPG. That is an improvement of 7 MPG over 12 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Specifications

The 2023 Toyota Highlander Hybrid AWD runs a 2.5-liter 4-cylinder engine paired with a automatic (av-s6), sending power through all-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
