Then I converted km to miles and L to gallons (not imperial). I came up with 31.38 mpg and 42.85 mpg, respectively. Somebody should double check these numbers, though.
Thank you for checking the numbers. I've also sent the inquiry to Subaru Canada and here is the response:

"Thank you for contacting Subaru Canada Inc. Here's some information about the different testing procedures between the United States and Canada:

Natural Resources Canada (highway procedure) - 16km trip with average speed of 77km/h and a top speed of 97km/h. The test runs 13min and does not include any stops. All vehicles are tested in 2WD and adjusted later to account for AWD weight, rolling resistance, engine load etc. The entire procedure is outlined on page 5 and 6 of the 2011 Fuel Consumption Guide.

EPA ( - The EPA tests vehicles at about the same speed (48.3mph = 77.7km/h) but they have three additional tests which were added in 2008. These include an air conditioning test, a cold temperature test and a high speed test which includes higher top speed and more aggressive acceleration.

The EPA also applies a 22% correction factor to highway fuel consumption while Canada only applies a 15% correction factor (

So it's apples to oranges comparing the two numbers.
Hope this helps!
