I hope people know to not take too seriously (or at all) the report card the car provides to help drivers learn efficient habits. Today was a new low for me: 56/100 over 22 miles of EV driving to town and back home using one kWh every 7.1 miles. That works out to almost 40 miles range from a full battery. I'm still not sure what part of my driving the Prime finds objectionable but the car did suggest at the end of my drive that I be more moderate with my cabin air conditioning. That was amusing since I used a fan set to high rather than A/C cooling. I do plan though on monitoring the battery temperature this summer in case the Prime is actually smarter than me and is warning against warm(er) cabin temperatures.
Between this post and that other "low climate score" thread, it appears the climate score is based on hard coded thresholds. Basically, if you set the temp to "LO" regardless of fan speed or A/C status, it'll give a low climate score. if you set the fan speed to HI regardless of temperature setting and A/C status, it'll give a low score.
My score improved to 74 today (a solid "C") during a similar but longer r/t. Consumption increased to 6.8 miles/kWh from 7.1 yesterday, I presume from A/C use. Unfortunately I don't have my BT adapter with me, so I cannot track battery temperature. No worries though -- I have all summer.
best i got was 97. that was 21.4 trip to work using cruse control @ 60 on major freeway and absolutely no traffic.
In addition to achieving the 99 score, I believe that driving exclusively in reverse will give you another 10, or so, EV miles by using the bottom 1/3rd of the traction battery.
Heck, if you drive the Prime exclusively in reverse, you'll not only achieve 100 ECO Score points every time, but the car will continually charge the traction battery while driving (in reverse) -- and you might never need to plug it in or even buy gasoline. This function is nearly impossible to find written in the owner's manual, so don't even try to find it unless you have a PDF version of the manual and search for it.
DavidA that is a physics impossibility. It can't run on electricity and positively charge the battery concurrently. It would be a loss system. So it would either need to run the ICE and use gas or use more electricity than it generates.

Oops, sorry I missed that. Unfortunately I have to explain physics to far too many people when talking about my car so I just assumed "jeez, not another one"
I know what you mean, but lots of these folks are engineers, so those kinds of jokes are pretty common ... sometimes at the expense of those who have no idea how the universe works.
