Real world fuel consumption

[grober]

Forget the glossy brochures this HONEST JOHN compilation allows people to submit their own experiences of fuel consumption in the real world. Has to be taken with a pinch of salt obviously like all internet stuff but makes interesting reading for prospective buyers? Mercedes-Benz | Real MPGs | Honest John

The danger here is that the data can be skewed by prats entering fake numbers.

Using spritmonitor or Fuelly, you can see averages and break them down to individual entries.

Very true although the real range figures may give an indication of "spread" it would be useful to know exactly how many submissions each of the HJ figures/averages are based on. I also wonder in what direction people are most liable to "massage " their consumption figures----- low or high . Interesting psychological question [ assuming they don't work for AUDI or BMW's Marketing department of course ]

As far as I'm concerned, "real world" mpg figures are no more meaningful than those published by the manufacturers. At least the latter serve to provide an indication of comparable figures for different vehicles.

The figures that people achieve in reality depend on countless different factors, including: driving style, road conditions, weather conditions, traffic density, distance travelled, starting temperatures, road gradients, weight of driver, number and weight of occupants, weight of items carried, use of air con, driving with windows open or shut, etc, etc, etc.

It makes me chuckle when I read about people getting hung up on the second decimal place of their cars published fuel consumption, yet being quite happy to drive around with a roof rack permanently in place and the boot filled with enough tools to rebuild Concorde!

Agree with much of the above. Allowing trip readings rather than brim to brim will tend to skew the figures upwards but at least it will grow to become a rough and ready guide. Furelly is probably more accurate by design although still subject to the potential of massage and requires some discipline to keep up to date.
