2013 Subaru BRZ: January Fuel Economy Update

February 4, 2013

2013 Subaru BRZ

You would think that a car like the 2013 Subaru BRZ or its Scion FR-S cousin would be the sort that underperforms when it comes to real-world MPG. Why? Because they beg to be driven, that's why.

Thankfully, that's not the case. The 2013 Subaru BRZ is EPA-rated to deliver 22 mpg in the city, 30 mpg on the highway and 25 mpg in the typical mix of each that we all really drive. In just under 6 months and just over 10,500 miles our BRZ has averaged 26.3 mpg. Compare that to its 25 mpg combined rating in order to be suitably impressed.

The first three months included many road trips, and during that period we bested the 30 mpg highway rating on no less than 8 fill-ups. Over the last three months it stayed closer to home and didn't get out on the open road much, but it still averaged 25.6 mpg and beat its EPA combined rating without the benefit of a single 30+ mpg tank.

You want to talk about range? We don't often run a tank dry, but our Subaru has gone as far as 356.9 miles between fill-ups. We put 11.4 gallons into its 13.2-gallon tank that day, so 400 miles isn't impossible in the right sort of conditions.

Of course all of this was done on 91-octane premium, the required fuel for this car.

    I'm guessing the FR-S has a lower overall average (24.2mpg) due to more track days. Out of curiosity, in the same type of driving situations, are you finding any differences in fuel economy between the FR-S and BRZ? Wondering how much the different tires might be affecting the fuel economy.

    It's hard to be certain which factor makes the biggest difference, but the stickier aftermarket summer tires on our FR-S affects the MPG two ways: 1) they have a bit more rolling resistance all of the time; 2) the extra stick encourages more spirited driving even on days the car isn't at the track. These tires probably make the FR-S the leadfoot's choice among the two cars when the sign-out sheet gets passed around.
