    I went on my afternoon cruise yesterday and drove 19 miles. It appears that it cost me $1.19 at 17 per Kwh. Had I driven my Pantera, the cost would have been about eight dollars to make the same drive. Nine miles per gallon and using two gallons of premium. Once I get my seperate meter installed it looks like my energy cost will be about 50 cents for the same drive! Incredible! So it cost me about 16 times as much to drive the Pantera. If my numbers are correct, this is way better than I expected! :biggrin:

    Can your Pantera run off sunlight? :)

    I wish it would. It might actually drop the temperatures in my neighborhood with all the heat energy it would absorb! :biggrin:

    No more oil changes, valve jobs, spark plug replacements, smog checks, etc, etc.

    But rear tire replacement costs may be similar...

    And no smelly toxic fumes from an overly rich fueled engine! Carbs are the worse, nobody can dial the mixtures right on them unless they have very precise instruments to calibrate them. Can't imaging driving an ICE convertable... cough cough.

    Yep. My daily commute went from 3 gallons of premium in my Corvette to $2 in electricity and it's more fun :)

    I actually tweeted about spending so much (fuel, but also money) commuting to work and back. And really 2 gallons almost gets me round trip, not just home.

    I did some quick math the other day:

    Not bad for a car that can do 0-60 in 3.7!

    Some can do even better than that! We put in solar panels at home and generate more electricity than we use--including charging the car. So Southern California Edison pays me to drive the car!

    Controlling the electric domestic water heater thru a 50 minute (max) timer > 50 Amp contactor removes a lot of kwh waste at this location. Seems like it might be more than actual Roadster usage, but who really knows?

    I ran through the numbers today and the cost/mile for the Roadster is even less than my wife's Prius by 18% and the Roadster is much more fun to drive.

    Prius
    Item.............Cost...........Miles.........$/mile
    Gas.............$3.50.............45........$0.078
    oil change...$35.00.........7000.........$0.005
    Tune-up....$100.00.....100000.........$0.001
    Tires.........$400.00.......40000.........$0.010
    .....................................................$0.094 /mile


    Roadster
    Item............Cost............Miles............$/mile
    Electricity...$0.085.............4.............$0.021
    Tires rear...$360.00........9500...........$0.038
    Tires front..$350.00......20000...........$0.018
    .......................................................$0.077 18% less than Prius

    This assumes I start to do my own servicing after warranty is us next year. I will likely do this as I have always performed my own maintenance, I helped the Ranger last two times and it is not much worse than the tune-up, but it is more frequent. :mad:

    We have had solar hot water for over 15 years. We love it! :tongue:

    Missing a factor!

    I assume your price per Kwh is your grid price. Since you lose about 25% going from grid to battery you need to adjust for that inefficiency. That raises your cost to about $0.033

    Also 225 wh/mile is "very good" - maybe 55mph? My average usage is about 250 wh/mile at 65mph when there is no net elevation gain and only minimal gross elevation gain.

    Wow, you guys get 225wh/mile and 250wh/mile? I struggle to maintain 280wh/mile. The current reading on the VDS for the past 600 miles is 295wh/mile.

    I need to tone down on the lead foot. Or maybe just the hills and stuff in Seattle area.

    On Saturday I drove 45 miles (40 miles on freeway), net elevation gain of 1,300', usually 60 - 65+ mph, temp were mid-60s, no heat, softtop, windows up and used ~ 280 wh/mile. The return trip was essentially the same route and I ended up at the entire 90 miles ~ 237 wh/mile - so the return was sub 200 wh/mile.

    In flat-as-a-pancake Florida, the slow-and-easy driving-miss-daisy days get me 270-280 Wh/mile with the A/C and ragtop off. More frequently I see 270-280, and it's about 320-350 if I'm in a hurry.

    Where are you getting 2 rear tires for the Roadster installed for $350, and what kind of tires are they? Yokos from TireRack installed by Tesla are $500.

    Hmmm... How about...

    Battery pack to last 100,000 mi and cost $30,000 to replace.
    That's $0.30/mi in battery wear and tear.

    Rear tires (AD07's) $750 to replace last (me) about 7500 mi.
    That's $0.10/mi in (rear) tire wear.

    So I'm already up to $0.40/mi.
    That battery replacement is the big unknown. Other stuff is close to noise.

    The local tire store sells me Contential DWS Extreme contact and they include mounting and balancing. To me they are a much better value as the cost is half and they lasted me more than twice as long as the intial Yokohama's. I think dry traction is not quite as good but if I really push the car it is the front end that loses traction first not the rear end. And the Contentials are better in the rain and even snow.

    As for the battery pack the jury is still out. Hans in Germany got over 150,000 miles from his battery and not sure if he pushed it at the end to an early demise. So it may last as long as the Prius. And I am hoping the price will be under $20K the when the time comes maybe even $15K.

    As for the watts/mile on relatively level roads at 55 I can be under 220 watts/mile. While I had a lot of fun earlier on I now mainly drive for range.

    After all I told my wife I got the Roadster to save money :biggrin:
