It's possible that the estimation is accurate/generous when there is plenty of charge left, and conservative when there is little charge left. This would explain why the car didn't actually die when the range estimate hit zero.
They may make the estimate conservative when there is little charge left so people are more apt to charge up.
- LnxPrgr3 14y agoFor what it's worth, my car's fuel gauge appears to do exactly this—no change from full for the first 60-100 miles, and about 2.5 gallons left on "empty." The first quarter tank lasts a good deal longer than the third, at least according to the gauge. You'd think you wouldn't want to do this with a range estimation because the error's more obvious, but I'm also sure they don't want to sandbag its estimate from a full charge because people will be wondering why they're not seeing the advertised range. I'm sure they do want the car to be able to keep going a little past empty, though, and those spare miles have to come from somewhere.
