Taking delivery of my P100D today. I love the performance of the P100D but the $40k premium continues to sting. I would have ordered the 100D if available at the time. Well, I get free supercharging! Does someone want to do the math on how many years it will take to recoup $40k at 15k miles a year with free supercharging? No? I thought someone might be bored at work.
Simple.
$40000 buys you 200000KWh assuming 0.20 per kwh in CA.
Assuming the following:
1) you only supercharge and never charge at home
2) 15K miles annually
3) average energy consumption is 310Wh/miles. This is a bit optimistic but I think this is what Tesla use to calculate their rated miles for a p100d.
4) 400KWh is free annually
You will have to pay for the 13709 miles out of each year for supercharging.
You will have used 4250kwh per year to drive those miles.
Factor in vampire drain and inefficiency in the charging lets say you use 4750kwh per year you have to pay.
200000kwh / 4750kwh = 42.1 years
So it will take you roughly 42 years to break even. But keep in mind inflation and such. I'm sure supercharging will cost more in the future and such.
Also keep in mind you wouldve driven
631,500 miles in the 42 year time frame. Your battery will be pretty much dead way before then or the charging inefficiency is crazy high it is not worth it to keep the same battery.
Point is you will never make your money back.
Just as most will note buying a tesla is never the lowest cost option if all you do is 15k miles a year. The lowest cost is to drive a used prius for the same miles and you will still come out ahead even if you never pay a penny for the electricity or maintenance to drive the tesla.
Point is enjoy the car and know it was worth your hard earned money to drive such a great machine. That is priceless IMO.
