I double-checked and yes, the nav screen said 5.8. There was probably a few miles left in her since I had just received the VLBW, but probably not another 10 mi....
Reddy.
Something isn't quite right. 60F is just a small hit on battery capacity, and if you had the heater blasting, we'd see that in the economy figure. Is it possible that the car sat outside overnight in significantly colder weather than 60F? Like 30F or 40F? Is it possible that you didn't reset the Nav screen economy before the trip began? Are you sure you didn't more than 101.7 miles?
First, we'll take a 0.1 reduction from the Nav screen to match the driver's screen, so 5.8 becomes 5.7
Your data....5.7 miles/kwh
85.2 miles to LBW... should be about
99 miles
13.8 miles to VLBW... almost perfect at
5.7 miles/kWh!!!!
There should be about 6 or 7 miles available at 5.7 until Turtle, and you only drove 2.7, so you still had 3 or 4 miles left (assuming the battery pack is reasonably balanced).
So, we've got a about 14 missing miles from fully charged to LBW. Is it possible that you started at 80% ? That would easily answer this question.
Number 23 checking in,
SIR!!! Well, here it is, my 2-yr anniversary, and I decided it was time for another run at the 100 mi Club.

I drove the same route as quoted above, but this time got scared and turned around 5 mi short of the destination. I was already down to 5 BB and the GOM was saying something like 35 mi left, so I decided to abort, and turn around. Well, long story short, I made it home with plenty to spare, so I circled the ranch until I reached 103.6 mi.
Here are the details. Winds light (SW@5), 75-80 F, charged L1 overnight, 6 TB, 12 BB (obviously), GOM=100mi which is considerably lower than my "norm" since I drove 40 mi on the freeway the day before). Much warmer than last year's run, obviously no heat used, but a little AC for the first few miles, then just fan for the remainder. Also different from last year, there was no power off at the turn around point since I aborted 5 mi short. About 3:30 driving time and 30 mph average (the last 30 mi was definitely slower). Guessing outbound 5-10 mi @35mph, 5-10 mi @50-60 mph, 2-5 mi @35mph, 10-20 mi@50-60 mph. Return the same except 25 of the last 30 mi was between mostly between 20-30 mph. Also note that I was averaging around 5.1-5.2 mpkwh when I hit LBW. I had just exited the freeway, slowed to around 35 mph and hit LBW at 70.0 mi. It was almost identical to the spot where I hit LBW on my last year's run so I knew I could get home. Don't forget, I turned around 5 mi early, so LBW was 10 mi earlier than last time. At this point, I figured wow that battery is really degraded and my days of driving long trips are over. So, I continued through city streets and along the river at 25-35 mph (route chosen for the speed limit), briefly jumped on the freeway, then back to city streets. I arrived home at just shy of 90 mi and still hadn't gotten VLBW. Continued circling and got VLBW at 93.4 mi (yes, that's 23.4 mi on LBW!), I continued circling for another 10 mi and still did not see turtle (I chose to stop at 10 mi because I had previously done this at 30 F last winter and found I could go 10 mi). Could I have gone another 5, 10, 20 mi before turtle? Perhaps, I don't know, but it was getting boring and I'd gotten the century, so I called it quits. Thus, as LEAFfan has shown, there are lots of miles below LBW if you drive slow enough. However, I was still amazed and thought maybe I had missed VLBW, but then I got the triple dashes at 93.4 mi so I knew I was on track. Also, I should note, it's a 2-yr old 2011 SL with 13,900 mi and I've never upgraded my software. This was a much more difficult 100 mi than my last trip. I ended up driving more miles in town at lower speeds, got better mi/kWh numbers, and had higher temperatures. But it was still tough, even with my previous experiences, I still aborted due to the unknown battery degradation. Finally, LBW came much 15 mi EARLIER than last year. Is it possible that Nissan has pushed some software on my car and LBW criteria has changed? Thoughts? I have no idea. No fancy CAN/GID/etc readers for me.
So, final stats: 103.6 mi, 6.0 mi/kWh dash, 6.1 mi/kWh screen, 70 mi LBW, 94.3 mi VLBW, 3:30 hr, 30 mph average.
