Estimates are from Japan Ministry of Territory, Infrastructures, Transport and Tourism. The mileage increase is an improvement over the 2021 WRX 2.0-liter engine which gets an EPA rating 20/27 city / highway mpg and 23 mpg combined.

We don’t expect a big difference in fuel mileage from the WRX S4, but the new 2022 WRX 2.4-liter engine gets a significant improvement in highway and combined mpg over the Boxer engine of 2. , 0 liters outgoing.

Like the WRX 2021, we expect the 6-speed manual transmission sedan to get better mileage than the CVT automatic models.
