4 more sets of numbers to report, as a followup to my prior post on this thread.
Per my regular 70/30 hwy/city mix -
5.93 L/100 km (zero A/C)
6.30 L/100 km (some A/C)
On a 1136.7 km total road trip (85 hwy/15 city, A/C running ~75% of the time) -
5.56 (!) L/100 km
In Monopoly money - 42.30 US mpg
In poker chips - 50.81 Imperial mpg
Back to the regular 70/30 hwy/city mix, and w/lots of A/C -
6.33 L/100km
...and back up to the low 6s I've been typically experiencing this summer.
It would appear that hwy running, for hours at a time, reduces the rate of fuel consumption.
Overall, these are substantial reductions from 7.1-7.2 L/100 km, when the car was still brand new thru the dead of winter. On the assumption that my driving style has been more or less the same, wear-in, usage mix, and environmental conditions seem to account for the rest of the difference.
I think my experience has been typical (no need to panic for the new Yaris owners).
Well, not much more I can add at this point. My Yaris has met all my expectations
