For reference using a Prius ~52 mpg combined (advertised) and current gas price in SF, for the drive from SF to LA:

383 / 52 * $2.61 = $19.22

Or a Honda Civic:

383 / 34 * $2.61 = $29.40

(Assuming their definition is one way not roundtrip.)



view as:

And in other US states and points in time, gas is cheaper. For example, in December in Greenville, SC gas was $1.90 a gallon which would make gas in a prius cheaper than the Tesla supercharger.

382 / 52 * $1.90 = $14

EDIT: From Tesla's blog post "What’s important is that in every region, Supercharging will remain simple, seamless and always significantly cheaper than gasoline."

Looks like Tesla will be pricing the electricity differently in different states as well. I wonder if the changes in their electricity prices based on the region will be enough to offset currently low gas prices.


With that said, I'm guessing that the current cost estimates are based on a Model S, which is a much larger car than either a Prius or Civic.

The Model 3 will most likely have significantly better range per kwh than the Model S, reducing the cost even more.


A Prius is surprisingly large inside. EPA cargo volume for the rear with seats up (5 passengers) is about the same as the Model S. The frunk adds an additional 5 cubic feet.

Yeah, good point. I mainly just picked those two because of popularity.

... but supercharging in SC will be roughly half the cost of what it is in CA, meaning the equivalent trip would only cost $7.50 in a Tesla.

However, the Saudis will soon raise the price of fuel to exorbitant levels (again), while electricity prices will remain stably regulated by each state's power commission.

They don't have that much control. The US would increase fracking / shale ops and bring the cost of oil back down. We have incredibly massive oil reserves here in the US that any sort of Saudi nonsense will have limited effect.

Saudis have gotten themselves into a world of pain over the past few years attempting to play their stupid games with oil prices, so much so that they are about to take Saudi Aramco public to get a desperately-needed cash infusion. Our fracking/shale ops are also hurting though in this race to the bottom.

the US AND Canada. About 40% of the oil the US imports comes from Canada. More than comes from SA.

My state allows for a per-kW, at-cost fuel rate in addition to the controlled base rate. So definitely not true everywhere.

I keep forgetting how stupidly cheap petrol is in the States. Their given example of Paris->Rome route is probably 1/2 cost of the diesel cost in the most efficient of diesel cars, which makes Tesla look very cheap to run on such a long route.
