Revisiting this thread, as I had confluence of a couple of events to day that allowed me to get a decent test in:
- I had four legs of driving spread out over the day totaling ~150 miles
- Mild weather all day (70's)
- I only started out with 70% charge (172 rated miles)
So, the actual total driven was 149 miles. I burned 144 rated miles. So I actually beat rated miles by 5. This includes any vampire loss throughout the day (which I didn't track, however I'd previously unchecked the 'remain connected' box, so it's been lower recently).
I suspect if I had driven the remaining 28 rated miles I ended up at home with, I could have actually put made that 29 or 30. Total average power used for the day was 268 Wh/mi.
The driving was a combination of highway and city stop-n-go. Speeds up to 75 mph.
Interestingly, we arrived at the show we were attending with about 93 rated miles. 2-1/2 hours later when we left, it was displaying 101, am increase of 8 miles, although about 5 of those were burned in the first 2-3 miles. But it appears that the 5-6 additional miles estimated were "really there" based on the 75 mile drive home.
The odometer behavior today, in addition to the somewhat funky previous behavior, makes me wonder if v7 might actually be basing range estimates on recent energy usage for the first time, rather than what appeared to be static estimates previously.
