I've heard the arguments about how that doesn't matter with regards to mpg, but it absolutely has an impact on mpg.
What I did is find what the Impreza CVT got highway in Consumer Reports' actual highway test, then took all the other vehicles that got that highway mpg on the same CR highway test. There were 12 others. I did not cherry pick, I took all. Pulling out the Impreza as it was a definite outlier left the Legacy as an outlier depending on one's definition. Since the Legacy was tested on the same equipment as the outlier and it was the closest to said outlier, I removed it too. This is valid.

What was left were 11 cars that averaged 35 mpg on the CR highway test. Those vehicles had, as EPA highway test results, 29.5 +/- 1.5 mpg. All of them. Statistically, if there had been a half million cars that tested 35 mpg on the Consumer Reports test, the Impreza would have had, at 4.63 std deviations, over a 50/50 chance of being the furthest out from the group.

Again, I think we might agree on that. Interestingly, the '14 2.5 liter Forester gets 14% better highway EPA mpg than the '14 2.0 liter Forester, both CVT's. I'm not sure why that is.

Another interesting point is that the '14 Impreza 2.0 liter test results are not out yet (as of today). Very interesting considering there are allegedly no changes...
