2007 Honda Fit Real World Fuel Efficiency

Some call this Fuel Economy or Gas Mileage

This page details our record of fuel use for this car. We really like the Fit. You can carry eight foot 2x6 lumber in the car! We are hoping to get a roof rack for a canoe but haven't yet decided whether to get the clamp on style, which many people recommend against, or the through the roof style which leaves small permanent anchor points on the roof.

The official efficiency ratings (l/100 km) for the 2007 Honda Fit are:
  City    Highway
  7.3       5.8

Our Observations

==============================================================
     Total fuel consumed =  6126.2 litres
      Total cost of fuel =  6956.63 dollars
  Maximum fuel price was = 1.489 dollars/litre on 2008-07-18
  Minimum fuel price was = 0.819 dollars/litre on 2008-12-18
Total distance travelled = 87628 kilometres
      Total CO2 produced = 14090 kg
    CO2 per km travelled =     0.16 kg/km
         Mean efficiency =     6.99 l/100km
   Mean fuel cost per km =     7.9 cents/km
    Purchase cost per km =    23.3 cents/km
 Maintenance cost per km =     4.4 cents/km
   Insurance cost per km =     6.8 cents/km
   Operating cost per km =    42.4 cents/km
==============================================================

With regard to the maintenance, we have done what the car has told us to do by way of the dashboard maintenance codes. Insurance on a modest car that is still reasonably new is about $1000 per year here in BC for drivers with the maximum discount of about 40%. Obviously, the per kilometre purchase cost will continue to fall and the other costs will rise. I suspect that, excepting the fuel, in the end they will all be about the same .

Figures

Fuel Use Versus Distance Travelled

Colours indicate the order of the fill-ups. Red is most recent and blue is oldest. The ROYGBIV rainbow order is followed (approximately). The lines show the official efficiency ratings: dashed is city travel and dotted is highway travel. Ideally we would want to see all of the observations between or below these lines. The red dash-dotted line is the best fit to the data assuming that the line goes through the origin -- it must, you don't use any fuel if you don't drive any distance. It seems pretty clear that if we could isolate the observations related solely to city driving the slope would be steeper (worse) than the official rating. Is this related to driving style? The car is driven by three different drivers. That variable is rolled up in the observations as well.
