2017 Toyota Avalon: MPG and fuel economy

This page collects every fuel-economy figure the EPA publishes for the 2017 Toyota Avalon. 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 2017 Toyota Avalon. 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 2017 Toyota Avalon compares

The 2017 Toyota Avalon returns 24 combined MPG. Cars in the Midsize Cars class for the same model year average 31.1 MPG, which puts this car behind the class average by about 23%.

The most efficient car in the Midsize Cars class for the 2017 model year is the Hyundai Ioniq Electric at 136 MPG. The bar chart below puts the Toyota Avalon alongside the class best and the class average so you can see the full picture.

For broader context, the average new car of the 2017 model year (across all classes) returns 26 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 2017 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 625 gallons (the car's annual consumption at the rated MPG).

Year-over-year MPG for the Toyota Avalon

The EPA has rated the Toyota Avalon across 28 model years, from 1995 Toyota Avalon through 2022 Toyota Avalon. 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.

Combined MPG has stayed in roughly the same range across the run. The peak rating came with the 2013 Toyota Avalon at 25 MPG.

Specifications

The 2017 Toyota Avalon runs a 3.5-liter 6-cylinder engine paired with a automatic (s6), sending power through front-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.

Common questions about the 2017 Toyota Avalon

Quick answers to the questions people most often search for when looking up the 2017 Toyota Avalon.

• Is the 2017 Toyota Avalon fuel efficient?

  Not particularly. The 2017 Toyota Avalon returns 24 combined MPG, which trails the average car in the Midsize Cars class for the same model year by about 23%.
• What MPG does the 2017 Toyota Avalon get?

  The EPA rates the 2017 Toyota Avalon at 24 combined MPG, 21 MPG in city driving, and 30 MPG on the highway. Real-world numbers depend on your driving style, the weather, and how loaded the car is.
• How much does it cost to fuel a 2017 Toyota Avalon per year?

  The EPA estimates an annual fuel cost of $2,500 for the 2017 Toyota Avalon. That figure assumes 15,000 miles of driving per year, a 55% city and 45% highway split, and the EPA's published average fuel price for the rated fuel grade.
• What fuel does the 2017 Toyota Avalon use?

  The EPA lists the 2017 Toyota Avalon as running on regular gasoline. Using a different grade than the manufacturer specifies can affect fuel economy and engine longevity.
• Has the Toyota Avalon become more fuel efficient over time?

  Combined MPG has stayed close to flat across the run. Both the earliest (1995 Toyota Avalon, 21 MPG) and most recent (2022 Toyota Avalon, 25 MPG) versions sit in the same range.
• How much CO₂ does the 2017 Toyota Avalon emit?

  Tailpipe CO₂ emissions are 365 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 5,475 kilograms of CO₂.
• What is the difference between the city and highway MPG of the 2017 Toyota Avalon?

  City driving returns 21 MPG and highway driving returns 30 MPG, a gap of 9 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise.
• What engine is in the 2017 Toyota Avalon?

  The 2017 Toyota Avalon has a 3.5-liter 6-cylinder engine.
• What transmission and drivetrain does the 2017 Toyota Avalon have?

  The 2017 Toyota Avalon comes with a automatic (s6) transmission and front-wheel drive.
• How does the 2017 Toyota Avalon compare to the best car in its class?

  The most efficient car in the Midsize Cars class for the 2017 model year is the Hyundai Ioniq Electric at 136 combined MPG. The Toyota Avalon returns 24 MPG, a gap of 112 MPG. If you are comparing on fuel economy alone, the class leader is worth a look.
