Let me get this, $10 of supercharging gets you 100miles, give or take? So it's about equivalent to 30 - 33mpg depending on prevailing gas prices? I thought it was much cheaper than that.

Unless my math is wrong...
I can charge my 80 kw battery for $7.20. ($0.09/kwh during night charging). In theory that gives me 310 miles of range. Lets be conservative and say 240 miles. 93 octane gas is $3.50 near me. So that $7.20 would buy me 2.05 gallons of gas. Over 240 miles that's 117 mpg, or 4.6 times more efficient than my E46. I think super charger rates are more like $0.25 / kwh. I mean, mine will be free, but even if it weren't, who cares? 99% of my charging will be done at home. |

I'm not computing home rates, I'm just going by the supercharger numbers and I was surprised.
The ole' 330i is hardly a model of efficiency. Having smelled that car on the NJ tpke (I had my top down when you accelerating at times near me), I'm not sure it's running all that clean. So the model3 will be a welcome change, I think you'll end up selling the e46. |

~80% of the miles on the S was from charging at home — and that icost significantly less. For the 5 years I had the CTS and Boxster, I averaged $195 per month in fuel cost. The Model S added about $30/month to our electric bill... I also drove it 100-200 more miles per month...

Ah that makes sense. So it's not like you were paying $10 (or 5 or 15) for each supercharger visit. Is the wholesale $2k cheaper than buying on the spot? Did it stay with your car/VIN?

Tesla started moving away from free supercharging about 2 years now. But until last week, you could get it with a referral. That ended over the weekend. It’s now pay per use for new cars. The rates vary by state, and there are 2 methods used: - Pay per kWh - some states allow reselling by kWh, and Tesla typically charges around 25 cents per kWh. Adding 100 miles range on a Model 3 should take about 25kWh, so about $6.25. The Model S is less efficient, so would take another 5-8 kWh, so would cost about $7-8. - Per minute. There are 2 rates - above and below 60kW of Power. 26 cents above and 13 cents below seems to be a common rate, but it can vary a few cents. This is harder to calc since the car charges a lot faster at lower battery levels, but the charge rate tapers down as the battery fills. I took my charging minutes and use the higher rate to estimate — and it still came up a lot less than I paid for the option on the S...
