Are New Subaru Models Fuel-Efficient? Check Out The Entire Lineup Here

With fuel prices rising, how fuel-efficient are the 2021 Forester, 2022 Outback, 2021 Crosstrek, and other new models? Check out the new model lineup here.

Are the 2021 Forester, 2022 Outback, 2021 Crosstrek, and other new models fuel efficient? An article from The Hill reports the American Automobile Association (AAA) says the average price of a gallon of gas is expected to increase by between 10 and 20 cents nationwide by August 2021.

That’s not good news for summer roads trips. How fuel-efficient are the 2021 Forester, 2022 Outback, 2021 Crosstrek, and other new models? The recent EPA Automotive Trends Report reveals Subaru is the number three automaker with the lowest greenhouse gas (GHG) emissions and best fuel economy.

That’s impressive as all Subaru models, except for the BRZ, come standard with all-wheel drive, which is generally less fuel-efficient than other configurations. Subaru increased fuel mileage in its new cars using new Boxer engines with direct-injection technology. They also use a stop/start system that shuts the engine off when the vehicle is idling and saves fuel.

With gas prices rising, good fuel economy is important to road warriors. Here are the 2021 and 2022 Subaru lineup and fuel mileage estimates for each new model and what you can expect on your road trips this summer.

All Subaru SUVs and cars run on regular unleaded fuel, so you don’t need the higher mid-grade or premium fuel. The WRX and STI sports cars do require premium fuel for the best performance.

2021 Subaru Forester fuel mileage

The 2021 Subaru Forester compact SUV comes with standard all-wheel drive and gets an EPA estimated 29 combined mpg and 26/33 city/highway mpg. The Forester comes with a 2.5-liter four-cylinder Boxer engine.

The EPA fuel mileage rating of the 2022 Outback XT 2.4-liter turbo is 23/30 city/highway mpg and 26 combined mpg. The estimated fuel economy of the standard 2.5-liter engine is 26/33 mpg city/highway and 29 combined mpg.

Subaru and the EPA have not released fuel mileage numbers for the all-new next-generation 2022 BRZ with the 2.4-liter Boxer engine.

The 2021 Subaru Forester, 2022 Outback, 2021 Crosstrek, and 2022 Ascent SUVs, with all-wheel drive, are fuel-efficient with the third-lowest greenhouse gas emissions. With gas prices rising, good fuel economy is essential to road warriors who want to get away this summer.
