2015 Subaru WRX – Impressive fuel economy continues

We’ve just finished running through the third tank of premium unleaded fuel since acquiring the 2015 Subaru WRX with CVT automatic transmission, and the fuel economy continues to impress.

This fuel economy figure is based on actual fuel used and distance traveled calculations.

Driving conditions are about a 90:10 mix of city to highway driving, in warm, summer conditions, average ambient temperatures 23-29 degrees Celsius.

  • Distance driven:  591 km
  • Fuel consumed:  55.851 L (premium unleaded, Husky Brand)
  • Calculated fuel economy:  9.4 L/100 km (30.05 imperial mpg)

(Disappointingly, the WRX’s onboard fuel usage display is quite inaccurate, showing an overly optimistic 8.6 L/100 km, a 9.3-percent error rate.)

The 2015 WRX’s fuel economy is remarkable.  With a 268 horsepower 2.0-litre turbocharged boxer-4 engine, CVT automatic transmission and full-time AWD, it’s is more fuel-efficient than our outgoing 2007 Mazda3 GT (with its relatively meager 156 horsepower 2.3-litre DOHC 4-cylinder engine 5-speed automatic transmission!)  And the Mazda3 has ‘only’ a front-wheel drive.  Under similar driving conditions, the Mazda3 GT typically returned 10.0 L/100 km (or 28 imperial MPG in mostly city driving.)

    Our 2012 Mazda 3 Sport GT with 2.5L 168 HP and 5 speed auto gets 9.2 L/100 km in city only driving.
