According to the EPA’s FuelEconomy.gov website, both vehicles will deliver 22 mpg in the city, 30 mpg on the highway and 25 mpg combined when equipped with the six-speed manual transmission. Opt for the six-speed automatic, and the numbers jump to 25 city, 34 highway and 28 combined.
To put that another way, the average BRZ / FR-S driver will use 13.2 barrels of oil per year if he rows his own gears, or 11.8 barrels per year if the car does the shifting for him. Manual transmission coupes will emit 355 grams per mile of greenhouse gas, while automatic transmission cars cut that back to 317 grams per mile.
Those manual transmission consumption and pollution numbers match the six-speed manual equipped Volkswagen GTI perfectly, and the mpg ratings are within one mpg city (with the nod going to the BRZ / FR-S) and one mpg highway (advantage, GTI).
A potential rear-wheel-drive comp would be the 2012 Mazda MX-5 Miata with a six-speed manual transmission, which will use 13.7 barrels of oil per year and emit 370 grams per mile of greenhouse gas (advantage, BRZ / FR-S). The Mazda delivers slightly worse fuel economy, too, coming in at 21 mpg city, 28 mpg highway and 24 mpg combined.
As we expected, the Subaru BRZ and Scion FR-s will be economical to run. We may not know what they’ll cost to park in your garage, but at least you can afford to drive them.
