Fuel tank, powertrain, drivetrain and estimated mpg from toyota.com's 2026 Highlander specifications page, read November 4, 2026. Range per tank is our arithmetic: tank size x combined mpg, rounded. It is not a Toyota figure.
What the range figure means
The range column multiplies toyota.com's tank size by the estimated combined mpg: 17.9 x 24 is about 430 miles for the gas grades, and 17.1 x 35 is about 599 miles for the hybrid grades.
Treat it as a rough ceiling, not a promise. Cold weather, highway speed, a full load, towing and short trips all lower real mpg, and most drivers refuel well before the tank is empty.
Toyota.com lists all-wheel drive as standard on every 2026 Highlander grade, so the table has no front-wheel-drive rows.
Fill-up tips
Use the fuel grade listed in your owner's manual and on the fuel door label for your Highlander.
Stop at the first click of the pump nozzle. Topping off past the click can overfill the evaporative system.
Do not wait for the low-fuel light on long trips. Plan stops on unfamiliar roads, especially in winter.
