Top 20 MPGe

Great addition to our individual stats. What do you think about adding/updating this to your first entry? How are we doing compared to our Volt neighbors? Nothing wrong with a healthy rivalry

 

I know I can't upgrade myself, my MPGe is probably only about 140 MPGe, but just thought I would share a late fall cool weather post!

 

Another 1,000+ tank. This tank has my new commute (20 miles round trip with one charge). The weather is getting colder. I have yet to block my grill

- 132 MPGe on EV
- 60 MPG on gas
- 82.3 MPGe combined

 

Nice.
Two charges per day would be ideal but I suppose finding a deal of parking + charging spot is asking too much in Manhattan

 

Ok, last entry until Spring.

 

My new entry for the list:



Since it is in km-liters I have calculated for you:
Distance: 1528 km = 1012 miles.
Combined km/l-eq: 42.75 = 100.5 MPGe
EV km/l-eq: 62.28 = 146 MPGe

Please update.

One may wonder how comes I am improving my summer results so close to Christmas, the answer is that November temps were exceptionally high here (all time high since starting measuring), the fact I did not need A/C (nor heating) since mid October helped too.

 

MPGe should be 100.5, you entered 99.7?

 

Your calculation is wrong and twisted.
Car is reporting to a certain accuracy, distance to the km (highest integer) and consumption to the liter (highest integer), you are ignoring car report by introducing more uncertainty that does not exist!
To your formula it should go like this:
Gas consumption 20 liters plus 0.5 liter for uncertainty equals 20.5 liters or 5.42 gallons.
133 kWh divided by 0.85 and 33.7 equals 4.64 gallons equivalent.
total gallons equivalent=10.06
1628 total km equals 1012 miles.
MPGe=1012/10.06=100.6

The other way to calculate (which gives same result) is per this post in the thread.

 

^ I appreciate your logic, but to make things more equal I would suggest that you press the big miles/km button on dash (is it in your Prius?) and take picture of your drive ratio screen in miles mode.

Or we let everybody take pictures in km mode to get more accurate results, but I sense endless math postings on this thread if we go that way.

 

Sorry, I don't have such a button, my car reports in km only.

 

I thought the reason we add 0.5 gallon was due to PiP displaying gallon rounded up.

If PiP displays liter, I think we should add 0.5 liter before converting liters to gallons.

 

Wait, doesn't the PiP round down? So if you had used 1.9 gallons in HV mode, would it not read 1 gallon used?

 

Yep! I believe you are right!

 

Problem is my (and European) PIP does not read in gallons but in Liters, so if i used 20.9 liters it reads 20. So the uncertainty in my case is 0.99 liters, so adding 0.5 liters to the reading before converting to gallons seems to be the right thing to do in order to (averagely) compensate for the uncertainty.

 

Yeah, I see both your and markabele's point. It's his thread, though - if you can convince markabele to offer non-US models a dispensation.
