EPA Says New Subaru Outback Gets Improved Fuel Mileage Vs Outgoing Model
The big news for the 2020 Outback model change is that it now comes powered by the Ascent-sourced FA24 2.4-liter turbocharged 260 horsepower, 277 lb-ft of torque four-cylinder Boxer engine under the hood. Subaru axed the six-cylinder 3.6R model in favor of the smaller 2.4-liter turbo XT and it gets significantly improved fuel mileage vs the outgoing model and it has more power and torque.
2020 Subaru Outback XT 2.4-liter turbo Boxer
The newly-available 2.4-liter turbocharged Boxer engine is part of Subaru’s Prominence 2020 Vision plan that calls for more fuel-efficient turbo four-cylinder engines. Subaru delivered it to Outback customers and the fuel-mileage estimates are much improved over the 3.6R six-cylinder engine that’s been discontinued.
The new 2020 Outback XT 2.4-liter turbo gets an EPA estimated 23/30 city/highway mpg and 26 combined mpg. That’s a substantial improvement over the old six-cylinder, which was rated at 20/27 city/highway and 22 combined mpg. And the 3.6R developed less power producing 256 horsepower and 247 lb. ft of torque.
2020 Subaru Outback 2.5-liter Boxer
For 2020, Outback still gets the standard 2.5-liter engine, now delivering 182 horsepower and 176 lb-ft of torque up from the previous 175-hp, 174 lb-ft. Outback’s 2.5-liter naturally aspirated Boxer engine features nearly 90 percent new parts, as well as direct injection and auto stop/start, and increased output and fuel efficiency.
The EPA’s estimated fuel economy is 26/33 mpg city/highway and 29 combined mpg. That’s a one mile per gallon increase over last year’s model. For 2019 models, the Outback’s CVT had a six-speed manual mode. The 2020 model change brings an 8-speed manual mode.
The new 2020 Subaru Legacy
The new 2020 Subaru Legacy also gets improved mileage using the same engines as Outback. The Legacy 2.5-liter Boxer is rated to get up to 27/35 mpg city/highway and 30 mpg combined. Those figures are slightly better than last year’s model, which could get up to 25/34 city/highway mpg and 29 mpg combined. Like the newly-revamped 2020 Subaru Outback, the biggest improvement in fuel economy for the Legacy is with its new turbo engine. The 2.4 liter Boxer gets up to 23/32 city/highway mpg and 27 mpg combined. Last year’s 6-cylinder could only get 20/28 city/highway and 23 mpg combined.
