The tire and wheel upgrade is no longer included when upgrading from the 60 to the 85. However, it is strange that you don't account for Tesla's profit margin. After subtracting $2000 for the supercharger package and dividing the remaining price of $8000 by 25 kWh difference, you get a battery price of $320. However, the implication of this is that Tesla's gross margin is lower for the base 85 kWh Tesla than the base 60 kWh Tesla. This makes absolutely no sense, and is highly unlikely. If we assume a profit margin of 25%, the battery price works out to be $240/kWh, which is a much more believable number.
You don't have to account for the profit margin. It is built into that price. That price is the retail price. We were not talking about Tesla's cost on the battery. No matter what we figure to be the price per kwh, the profit is built in - since we were talking retail price. So, if there are NO other differences in the 60 and 85 except the SuperCharger fee, you are right, that is $320 per kWh that Tesla is charging (retail) to upgrade from a 60 to an 85 kWh battery pack. That INCLUDES profit (or it may not, but of course it does). No matter what it includes, $320 is the price Tesla charged for the difference between the 60 and 85 (assuming no other differences than the SuperCharger access fee of $2k). So, if they can sell the customer a kwh, including profit for $320 per kWh, why wouldn't they be able to on the Model 3? And if you're right, that would be a price difference of only $4800 between the 40, 55, and 70. And theoretically, Tesla COULD pass on the battery savings from the GF (and still have their profit built in) and that would reduce the retail cost from $320 to $224 per kWh, which would only be a price difference of $3360 at each step (just to account for the battery pack increase, not any other changes).
