    This morning, I charged my 60 kWh car up to 187 rated miles (89.9% of 208). My energy screen on the center console shows the following average numbers:
    271 Wh/mi, 213 mi projected range
    288 Wh/mi, 201 mi projected range
    263 Wh/mi, 220 mi projected range

    so multiply:
    271*213 = 57723 Wh
    288*201 = 57888 Wh
    263*220 = 57860 Wh

    Assuming the energy screen is accurate, these readings seem to indicate that the battery at 89.9% has about 57.8 kWh, so full charge (57.8/0.899) would be ~64.3 kWh! Are others with 60kWh cars seeing the same thing? What would similar calculations show the full capacity is for the 85 kWh cars?

    Will be interesting to see what the car reports as energy used when running the battery close to 0 to see if it matches the numbers, whenever someone happens to do this with a 60 kwh battery.
