I've seen some state that Volt estimates the range better than Leaf. I wonder whether it is true - and if so, what are the differences.

From what I read,

- Volt uses last 15 miles of travel to estimate the range. Leaf seems to use about last 5 miles.

- Volt apparently takes pre-heating into consideration, while Leaf doesn't.

But, it seems to me the difference is also psychological.

- Volt can run all the way to EV range being zero, so it is easy to figure out the actual range.

- In Leaf you get battery low with some 15 to 20 miles of range still left. So, unless someone actually runs all the way to turtle, Range to battery low (or the last bar) becomes psychologically more important than actual range one would get

- Volt range being small, a difference of 5 miles seems trivial i.e. if the range estimator said 40 and they got 35. With Leaf, if the range estimator said 80 and they got only 70, the guessometer gets a bigger blame.
