The EPA has revealed the next-generation 2022 Subaru WRX fuel mileage estimates. The larger FA24 2.4-liter turbocharged Boxer engine gets a three-horsepower increase over the outgoing 2.0-liter turbocharged engine (271 horsepower vs. 268 horsepower), and the fuel mileage estimates changed slightly.

The EPA just released 2022 Subaru WRX fuel mileage estimates with the 6-speed manual sports car now getting 19/26 city/highway and 22 combined mpg, a drop of one mpg over the 2021 model. The 2021 WRX 2.0-liter engine had 20/27 city/highway and 23 combined mpg.

But the 2022 Subaru WRX with the Subaru Performance Transmission (CVT automatic) improves one mpg city/highway. The 2022 WRX CVT gets 19/25 city/highway and 21 combined mpg. The 2021 WRX 2.0-liter engine with the CVT had 18/24 city/highway and 21 combined mpg.

Subaru says they improved the 2022 WRX Subaru GT’s Performance Transmission, and it now offers up to 30 percent faster upshifts (2nd to 3rd) and 50 percent faster downshifts (3rd to 2nd).

Subaru improved the CVT fuel mileage with a ratio coverage range that has been enlarged, and lower ‘fixed’ gear ratios “have been revised to improve acceleration and response,” according to Subaru.

Subaru says, “The automatic transmission incorporates adaptive shift control that can quickly respond to perform rev-matching downshifts under braking, maintain the ideal ratio through corners, and respond faster on corner exit.”

Another change Subaru made to the all-new 2022 WRX 2.4-liter turbocharged engine is it does not require 91 octane premium unleaded fuel. Subaru says 91 octane premium fuel is recommended but not required. The EPA tested the 2022 WRX using premium gasoline.

The 2022 WRX with the 6-speed manual will be 130 lbs lighter than CVT-equipped models. Because of the weight difference, the 6-speed manual trim levels will be quicker, faster and still get better fuel mileage than CVT models.

When will the 2022 Subaru WRX arrive in the U.S.?

The 2022 Subaru WRX should arrive in the first quarter of the year. There could be delays with production because of the ongoing supply chain shortages. Stay tuned.
