The 2023 Subaru Ascent is third best with 22/15/32 combined/city/highway mpg. The Mazda CX-9 ties with the Ascent getting 22/15/32 combined/city/highway mpg. The Ford Edge SEL 2.0-liter EcoBoost is fourth, getting 22/15/31 combined/city/highway mpg. The Toyota Highlander is fifth with 22/14/32 combined/city/highway mpg.

How does Consumer Reports conduct its fuel mileage tests?

CR says its fuel-economy tests are conducted on a track and public roads. Testers splice a precise fuel meter into each test car's fuel line to measure how much gas is consumed. Each vehicle is then run through highway and city drive loops, with each performed multiple times by two drivers.

What sets the Ascent apart from other 3-Row SUVs?

The 2023 Subaru Ascent is designed for families with active lifestyles. The family hauler comes standard with Subaru's Symmetrical all-wheel-drive, 8.7-inches of ground clearance, and X-Mode and dual-function X-Mode for improved off-pavement, mud, sand, snow, and dirt road capability. Ascent also gets the highest Top Safety Pick+ crash scores from the IIHS.

Among midsize SUVs in the new side crash test conducted by the Insurance Institute for Highway Safety (IIHS), the Ascent was one of the models earning the highest “Good” rating. 

Having an SUV with all-wheel-drive usually means sacrificing fuel economy, but not with the Ascent. Subaru uses a direct injection 2.4-liter turbocharged four-cylinder Boxer engine for efficiency, and the automaker also uses the Continuously Variable Transmission (CVT) automatic, contributing to better mileage in the Ascent.

What type of gas does the Ascent SUV require?

The Ascent runs on regular unleaded fuel, so you don't need the higher mid-grade or premium fuel to get the best fuel mileage.

What is the price of the 2023 Subaru Ascent?

The newly-refreshed 2023 Subaru Ascent arrives in Subaru showrooms this Fall. Pricing will be announced closer to the retail launch, but expect a price increase with its new features.

In Consumer Reports new fuel-economy tests, the 2023 Subaru Ascent ranks among the top five most fuel-efficient non-hybrid midsize 3-Row SUVs you can buy now.

32 mpg? Where was this information taken from? Where is the data that shows the difference between the 2023 and prior model years? I'm lucky if my 2020 gets 25 on the highway. Worst vehicle I've ever owned. Waiting for a highlander to come in to get rid of this albatross.
