Best way to measure high MPG
It all started with this photo in the share section:https://www.greenhybrid.com/share/fi...100MPGBars.jpg
Too bad it's not metric so you can have measurements above 99.9 MPG (>2.35l/100km)

It seems to me that measuring using the Canadian MFD would work fine (if not the best), since you can have measurements as small as you want, equating to very high mileage. How would it be worse? Here's what your screen would sorta look like if you used the Canadian version to do the same type of trip: http://schwa.kicks-***.net/img/fake-mfd.jpg If you got higher than 100 MPG there would be smaller bars on the graph, and a smaller number as an average, so it would be rather easy to test for even higher mileage. The problem with the Canadain version of the graph is when your consumption is over 10L/100km, but that's not often. |

Hi Schwa:
___The Japanese version of the Prius II has a metric display although it too is lacking the necessary > 40km/L range. There are hypermilers in Japan that have rigged up a neat metric display with Insight like characteristics (metric display w/ resolution down to I believe 1 L/100 km and multiple trip meters). Hopefully Krousdb can elaborate further as I believe he has pics of what they have available to them across the Pacific … ___With that, Krousdb has a neat method of determining FE above 100 mpg in the Prius II over any given segment with a little math thrown into the mix. It works too :D ___Good Luck ___Wayne R. Gerdes ___Waynegerdes@earthlink.net |
Re: Best way to measure high MPG
The Canadian MFD is pretty good, resolution down to 0.1 L/100km, Toyota really should have splurged on the extra chip to hold both versions of the program in the MFD, especially in the US version, and Canadian as well so we can compare more easily. It might help the metric system grow in popularity, who knows?

The Japanese MFD shows your average in kilometers per liter up 99.9 I assume. That equates to 235 Miles per Gallon.

Re: Best way to measure high MPG
After doing some more research, I can't be sure that the Japanese version will exceed 40 km/l.
There is a gadget called a SuperMID M-1 / T-1 which will report losts of interesting info up to 99.9 km/l. http://babelfish.altavista.com/babel...FNENPIKEI.html I hope that mine will arrive by Friday Aug 5 so that I can have it installed for the marathon. THe additional info that it provides will be able to help me hone the technique. It should be especially helpful for winter driving and determining what winterizing mods work and which are a waste of time. |

Personally I find the fuel consumption type display more useful because it tells you how much fuel the car is using at that moment, and it's pretty shocking to see just how much energy it takes to do something (like taking off quickly up a steep hill) but it's not so obvious when the units are fuel efficiency because it's low numbers, with big steps in consumption between each number.

Re: Best way to measure high MPG
Two things
if your car is getting over 100 mpg which is wonderfull why does it matter ?? the difference between 98 and 102 mpg is very little. 2.4L/100km = 98mpg and 2.3L = 102 mpg. second if you want to know simply take your mileage and divide by gallons pumped into your tank. |

Thanks Schwa. I couldn't have put it better myself!
