2009 Honda Fit: Wonky MPG Number
March 13, 2009
Ever since the revised EPA fuel economy testing regimen came out, I've found it to be a generally good indicator on what to expect. The 2009 Honda Fit Sport checks in at 27 mpg city and 33 mpg highway. So I was a little surprised to see on Donna's fuel-economy rundown that somebody previously got 37.1 mpg as our best mpg. In checking the fuel log, I noticed that the fuel-up was during the car's track testing. Normally, that would be a cause for worse mpg, not better. Either way, though, the 37.1 mpg number is circumspect.
I would dismiss it entirely, yet there's another similar number on the Fit's log. It's 36.9 mpg after 359 miles of driving by somebody unknown.
Curious to get a number of my own, I drove 161 miles on the freeway yesterday as a test. I wasn't trying to maximize fuel economy but rather just be steady and realistic. I used a lot of cruise control to stay at 72 mph, with a few increases to 75 mph to pass. The topography was almost all flat except for a few initial miles of downhill that required little or no throttle. The final result was 32.6 mpg.
One item of note: the in-car fuel economy calculator had a wildly different number. It showed 41.5 for that same stretch. I cannot explain it, but we've found in-car calculators to be innacurate in the past.
Obviously, it's still very early in the Fit's one-year stay with us. More fill-ups will give us a better statistical average than we have right now.
