Just noticed today. On the SOA website, the Crosstrek is rated at 33 mpg highway which seems reasonable given the higher stance. Then I looked at Edmunds and both the 2012 and 2013 Imprezas are listed as getting 25/33 mpg. If you look at the full review that Edmunds did on 10/11/2011 they wrote "Getting the CVT improves those estimates to 27/36/30"
Seems that SOA is lowering the numbers.
