It's odd that there's no information on the plain 70 on fueleconomy.gov. There was apparently a plain 90 that was available for order at one point, but it's not clear if any were sold. I also found Tesla's statement that the 90 kWh models get "about 6%" more range that the equivalent 85 kWh models, even though fueleconomy.gov shows them as having the same range.There is a 70 without the D, there is not a 60D or 90 without the D.
I think I have it all sorted out now, with rated range numbers for all the models as shown on the updated battery capacity chart and the new chart of survey vehicles by model.
