Well, it predicts depending on how you have been driving. If you change the way you have been driving (like going from 30 mph city roads to 70 mph highway) obviously the est range won't be correct.SanDust wrote:The mileage estimator is a random number generator.
All auto makers have a simulation software that can tell you the watts/mile - given the speed. All that the software needs to figure out is the speed and likely speed variations. Then take elevation changes into account. The speed can be guessed using past history, speed limits and the traffic conditions. Given a destination, the software can figure out all this.
BTW, one of the things people crib about Leaf is this. It shows, let us say, 70 miles of range. Then, the person drives for 20 miles and now it shows 40 miles of range. The person somehow feels "cheated" !
One option would be to show the expected range - along with the speed used to calculate that range. If the driver drives faster, he should expect lower range.

On my 'old-fashioned' combustible engine vehicles, there is no mileage indicator on my fuel gauge, and those gauges have served me well for many years.
My Chevy Malibu has a "fuel range" indicator, and it doesn't seem to be any more accurate that the LEAF's estimated range indicator. The main difference is that the Malibu has about 300 miles range per tank given my normal route and style, the LEAF will have substantially less.mbutter wrote:On my 'old-fashioned' combustible engine vehicles, there is no mileage indicator on my fuel gauge, and those gauges have served me well for many years.
I'm not finding it to be even close in that regard.evnow wrote: Well, it predicts depending on how you have been driving. If you change the way you have been driving (like going from 30 mph city roads to 70 mph highway) obviously the est range won't be correct.
It's memory isn't that long. If you spent the last couple of miles before getting home driving city streets, that's what it will remember.GroundLoop wrote:I'm not finding it to be even close in that regard.
For example, for three days I did mostly freeway driving, at ~70mph. My range was around 65miles, as expected.
On the fourth day, after a full charge, I can STILL get into the car and see a predicted range of 80 to 90 miles. This is totally bogus. It does not reflect the way I've been driving. I would expect it to predict 65 miles of range, or stick to some reference point that is consistently off. Instead, it seems to have some kind of built-in "optimism" about me changing my driving habits.
