Apart from meaningless PR statements like “40 cents to charge”, have any real numbers (in kilowatt-hours) been published for what a full charge of the Volt would take?

Energy consumption is expected to be ~250 watt-hours per mile in the city cycle. For battery-health and longevity, they plan to use only half its 16KWhr capacity, between a state-of-charge between 35% and 85%. This means 8KWhrs of electricity constitutes how much it takes to charge it to achieve the desired 40 miles all-electric range.

Of course, 40 (miles' worth) times 250Whr is 10 KWhr, not 8, so something is different from the stated design goals. Either it actually uses less than 250 watt-hours/mile at low speeds (possible, given the Tesla's demonstrated consumption rate is lower than 250 watt-hours/mi at some speeds), or they've widened the proposed range of discharge they intend to utilize. Or I'm missing something completely.

I have seen no real numbers on the Volt. Honda's requires about 6 hours / 26 kwhrs to fully charge with a range a little over 100 miles. The off-peak cost would be a little over a dollar.

If they are referring to the first 40 miles before the engine kicks in, the 40cents (1 cent per mile) compares closely with the Honda numbers.
