I got the math right, and confused your 5.3 for my 5.1. By the way, that trip I made was right at 5.3 and 45mph the whole until I needed the darn heater at the end. 100 miles, though, but with some pretty agressive hyper idling the last several miles to offset the heater.
I just did 65 mi (4.6 mi/kwh) at 32 F last weekend. I started with 11 bars and used about 10 - 11 bars (I don't remember exactly, but I don't think there were any bars left), getting the LBW at around 13 mi (GOM). I finished with about 7 mi (GOM) remaining. No VLBW or Turtle so I knew I would make it. Drove 50-60 mph going and 30-40 mph returning. That's about my anxiety limit. I might try for longer distances when the weather warms up (even 45 F is easier). No heat is tough on the feet. Why can't Nissan let us put the air flow on window only? :evil:

ok have another report

this is the "other side" of our driving needs. the Centralia trip aka; mostly freeway!

its 62.6 miles RT with SO work schedule of 9:30 am to 8 PM. I - 5 entrance at Pacific Ave in Olympia exit 107 and exiting in Centralia exit 81 (its actually about 53.6 miles freeway)

trip going 60 mph, heat on all the way. temps about 42º with drop off of Son to daycare which is a total 7 block detour required from negotiating one way streets. i pick him up in the evening.

trip home 39º speeds ranging from 55 to 60 and heat toggled. i told her how to read the SOC and what to look for but she was paranoid anyway. missed LB since it was on a "blinking 6" when she got home at 64.1 miles and 3.7 miles/k.

i took it out and ran a circuit at 35-40 mph until i parked it at 79.3 miles and 4.1 miles/k. SOC 3% GID 8.

naturally, she would not believe i could drive it another 15 miles on a blinking GOM!!

Well.... if we go back and compare the various assumed battery temperatures, this one doesn't fit.

You had another mile or three left, so 82 miles / 4.1 is 20kWh consumed.

We absolutely need a way to measure the battery temperature, because there is far too much variation. Or some other factor is in play that isn't obvious.

ya problem on this one is i did not do the first 64 miles so have to go on what i am told and this is from a person who does not like to drive Leaf in winter and so can only go by what she tells me. now, the Leaf sits outside at her work but was pretty warm and sunny temps were upper 40's but temp drops fast when Sun goes down so it gets pretty cold but does not tell us how much heat the pack absorbed since it is sitting on asphalt which can warm up quickly in full Sun.

another thing i was talking to her so missed the VLB warning as well...

I hope she's more comfortable with range with the Gidmeter and your demonstrated extra 15 miles.

We have a 65 mile RT, all freeway run today, with a full load. Can't wait to see the S.O. pucker factor on the way home.

the wackiest thing I'm seeing with this warm couple of days up north here is that it appears to be much easier to achieve a higher efficiency/MPkW at 50 degrees than say below 30-40 f. It also appears that acceleration is improved noticeably. has anyone come up with a possible explanation for this? I've been using Zero Climate control consistently.
