Tesla showing how much more expensive they are compared to a petrol equivalent.

[plisken]

I occasionally browse existing stock, not that I would ever by another Tesla but it does give me a chuckle now and then.

Anyway, I was browsing and stumbled across a model S and was a bit surprised to see that they are being quite honest about the fact it will cost more to charge this than an equivalent petrol car.

It gets even more interesting or depressing if you fiddle with the mileage, petrol economy and local charging cost to better suit personal ciscumstances , as per my example below;

 

[The_Cable_Guy]

how does that work, simple terms

average 333 KPH,
3 miles per KW

100KW = 300 MILES

100KW @ £0.39 PPKW = £39.00

petrol @ £1.50 PL

300 miles @ 40mph= £51.14

how bad is the model S at efficiency?

If your average charging cost is indeed £0.73 / kWh, I feel sorry for you. And yes, an EV might not be best suited to your needs.
Mine, and a lot of others who can charge at home are closer to £0.1. I let you do the maths with that..

As always, YMMV...

And in other news... bathing in liquid gold costs far more than bathing in water. AND it kills you. So we should all definitely stick to bathing in water for now.

If I had to pay 73p per unit for all my charging I'd not have bought an EV. As nice as my MY is to drive, the determining factor in buying the car was the ability to "fill 'er up" for £7.50 (at the current elevated, hopefully temporarily, rates).

No residential customer is paying 73p pKw

I think the responders to this so far are missing the point being made by @plisken ?

It being that it is very honest of Tesla to have this facility on their website so you can tailor the estimates to your circumstances, and so can make an informed decision.

I do agree that 73p is a bit OTT of course and reflects the higher end of the rapid charging pricing range which you wouldn’t use day to day.

6000 miles at 1.5 gbp per litre and is 200 pounds a year for petrol?

Just take your calculator
For the screenshot with 6000 miles and 45 mpg:
for 6000 miles you will need at least 8 full tanks, 80 ltr each, at 45 mpg (133 gallons / 604 ltr)
that is £906 gbp. not £200 for petrol.

For the screenshot with 10,000 miles and 25 mpg:
for 10000 miles you will need at least 10 full tanks, 80 ltr each, at 20 mpg (400 gallons / 1818 ltr)
that is 2727 GBP, not 700 GBP

there is a clear error in values what tesla display for the petrol usage - they are missing one digit in front..

that is the thing that everyone in this thread is missing, I see

You are correct but the error was actually not a missing digit but that the price per litre of £1.50 is being treated as the price per gallon so the figures are out by a factor of 4.5

 

[Bouba]

There is some bad maths going on....they have confused gallons with litres...I assure everyone that petrol in the UK isn’t £1.50 per gallon....also, no petrol equivalent of an S saloon is going to get 45 mpg

Funny thread. Tesla ‘honesty’ is actually Tesla ‘silly maths error’.

I admire your tact. I would call it an absolute cluster****

 

[DoricJim]

Oops, I didn’t even look closely at the numbers in the screenshots

 

[ICE5891]

0.73 is brutal, I charge at 0.25 and is expensive because the company that manage my building did a bad electricity contract. If I could use a spot price contract like I have at home it would go down to 0.05 charging during the night. Then the difference would show up.

Probably a new AI/ML model

Hehe, no I'd reserve that to describe FSD (in this country at least)

Electric rates here are $0.09 / kwh. 1 kwh = ~~3 miles $0.09 / 3 miles = $0.03 / mile.

Gasoline here is ~~ $3.00 / gallon 1 gallon = 30 miles $3.00 / 30 miles = $0.10 / mile

Only considering fuel costs -

If currently a Tesla is $20,000 more than a comparable ICE vehicle, then (at today's prices) $20,000 / $0.07 = 285,714 miles. So in that many miles, fuel savings alone would pay the difference. But that's a long time and a lot more miles than most people put on an ICE vehicle. Further the price of energy will likely change so much by that time, calculations made now will be meaningless then.

On an electric vehicle, other costs could actually be more significant than fuel? No engine, transmission, exhaust system or brake maintenance, will likely outweigh the fuel savings.

The bottom line is really what kind of vehicle will best fit your needs and make you happy, considering your position on the importance of sustainable energy and the best way to achieve it. The economics just aren't that significant.
