We have had our Model S for 7 months now and I decided to take a simplistic look at energy cost for those 7 months:
Total Miles: 4,597.5 Total kWh: 1,703.8 Wh/mi: 371 Cost per kWh: 11.6 cents Total Cost: $146.87 or 3.19 cents per mile
Now, last week I decided to adjust my driving style, no insane mode launches, slower starts and slower overall speeds. IN OTHER WORDS, BORING!!! I was able to average 336 Wh/mi (I'm sure i could do better still but a 10% improvement vs. my lifetime average).
If I swap out this metric for the actual lifetime kWh used I would have used 1,544.8 kWh at a total cost of $133.17 or 2.9 cents per mile, a savings of .29 cents per mile. That's a savings of $13.70 over the 7 months, $1.96 per month OR $23.52 annualized.
So what's my point? I for one am no longer worried about 'Splitting Pennies' and will enjoy the heck out of our P85D (soon to be L). I'll save the $23.52 somewhere else, maybe one less Starbucks a quarter :biggrin:
