2013 Scion FR-S: Fuel Economy Update for July

August 5, 2013

2013 Scion FR-S

In July we installed a supercharger kit on our long-term 2013 Scion FR-S project car.

Since then, we've added 1,246 miles to its odometer using 66 gallons of 91-octane fuel. We retested it, re-dyno'd it and passed the 20,000-mile point.

We averaged 21.36 mpg during July and dropped our overall lifetime average by two-tenths of a point.

Worst Fill MPG: 16.9
Best Fill MPG: 30.0
Average Lifetime MPG: 23.8
EPA MPG Rating: 25 Combined (22 City / 30 Highway)
Best Range: 335.1 miles
Current Odometer: 20,459

  • At least I lived long enough to actually see you guys add 91 octane to a vehicle. Cue the Hallelujah chorus...

    I would like to see a full month of usage on the supercharger (since I'm sure you leadfoots would take advantage of it)... any chance we will see acceleration figures any time soon?
