Electricity is 20% of the cost of equivalent gasoline? To whom? Not me. Let's assume there's 34,020Wh of energy in a gallon of gasoline (per Wikipedia). I pay $0.12 per kWh in Austin... so 34 of those would be $4.08. As we all know the price of regular gasoline is just over $2. A car of the Tesla Model S caliber would almost certainly be using premium gas, but that is still on sale in Austin for as low as $2.69 (and as high as $3.49, yoikes who are they kidding?) $4.08 is a lot more than $2.69, never mind "20% less expensive." Perhaps Evannex are referring to Superchargers.
Per mile not per btu/watt.
For 34,020 Wh you get 89-95 miles. AWD D version Monroney sticker not out yet.
2014 Audi A8 V8 21 MPG combined. 2014 MB S-550 20 MPG combined.
Since Model S is 90% efficient vs ICEv ~25% efficient.
Bottom line is how much something cost to drive. Not price per btu/watt purchased.
To "fill up" your Model S 85 would cost $10.20.
And get you 265 EPA miles.
In the S-550 you would need 13.25 gallons of premium at ~$3.03 or $40.15 to travel 265 EPA miles.
$10.20 /$40.15 = 25.4%. After the fall in Gas prices recently.
As always YMMV depending if you drive like granny or a bank robber.
