2012 Subaru Impreza: Ekeing Out a Tenth
July 24, 2012
It's hard work pleasing the Impreza's MPG regulator. But I managed. When I started home for the evening, the average MPG meter indicated 27.0 mpg. On the way home, I watched it climb. Slowly. More than halfway home, it seemed to hang at 28.8 mpg. I had to put it over 29, and was running out of time.
I stopped glancing at it for awhile. Refused to acknowledge its existence. I finally looked over and it had jumped to 29.1 with about five miles left in the commute. Victory. Over 48 miles, I averaged two mpg better than my colleagues before me. I have no idea the significance of this claim.
I wasn't done. On the way in today, I was gunning for 30, but could only scratch out was a measly additional three-tenths. On both legs, I kept it around 70 mph and tried to keep the powertrain at around 2,200 rpm, its apparent sweet spot. A few passes required grabbing the paddles for whatever constitutes a downshift in a CVT.
Assuming the average mpg info is optimistic, it's still in the ballpark of what the 2.0-liter/CVT promises for EPA combined mileage (30 mpg). Not bad, although we're observing a combined MPG of just 25.2 since the Impreza joined our fleet. We measured that number at the beginning of the month, however. We've put an additional 600 miles on the Impreza since then.
