What would gasoline cost you to drive the same number of miles in a month?
I answered that in https://www.tractorbynet.com/forums...c-vehicles-today-post5612743.html#post5612743
At $0.18/kWh my 380 Wh/mile Model S costs $0.0684/mile. Divide that into your cost of gasoline to get the dollar equivalent MPG. At $4/gallon it is 58.5 MPG.
$-per-gallon / ( $-per-kWh times 0.380 kWh/mile ) = dollar equivalent MPG
Replace 0.380 with 0.260 for the newer more efficient Model 3.
Math Is Hard
