Can anyone explain how the EPA testing is done, and what the probable outcome of the EPA testing will be? I keep hearing about how the EPA has toughened up it's testing, and there's something about multiplying with 0.7. Have the Nissan Leaf, Mitsubishi iMiev been tested using the new test protocol? Was the Roadster tested using the new protocol? Googling it doesn't seem to be helping. I can't quite make sense of it. Basically, what I'm wondering is how much discrepancy can one expect between the EPA value and the 55 mph-value? And how will the Model S range compare to the other electric cars on the market?
