    So if you had 5 EV miles when you start the car, you're telling me the car is smart enough to know which of those EV miles came from the plug and which were residual from regen? I've not observed the decrementing/cancelling of HV-regen'd miles behavior you've described.

    This one I'm not sure I agree. We are only talking about HV operation in the power ranges where "EV" comes on the display, or subsequent to a lot of regen and enough charge to put a mile or more of EV range back on the clock. Regen used otherwise certainly counts towards HV mode.

    yes...it seems to give you a pass on a few regen EV miles. But if you rack up a lot it backtracks and cancels the kwh for those until you charge from the wall again.

    I'm referring to large elevation changes (or, if my wife's driving the car, a lot of braking from high speeds ;)). I've seen ~8+ miles of regen on long downhill stretches. If I get off the highway and switch to EV mode, then those count towards EV miles even though they should be HV miles.

    I agree with your observation here. It seems it's not the EV miles showing that's at issue here. But 3PriusMike suggests that the EV (kWh consumed) side of the screen that displays respective EV/HV usage will subtract the kWh consumed that result from any HV-regen'd miles.

    Any of the more techie folks want to chime in definitively?

    My strategy is to charge once a week to cover very short trips.

    Gas price kept on dropping. $1.89 around here. It doesn't make sense to use electricity @137 MPG unless my trip with gas would get less than 43 MPG.

    wow, still 2.50 here. even if it keeps dropping, i'll stay with ev, too many other reason besides cost. think of the poor tesla driver though...

    Why poor tesla driver. Theyd paid a premium for the car and shouldn't expect a return on it anyway....Electric should still be cheaper anyway

    Model S 85kWh is rated 89 MPGe. With 18 cents per kWh electricity here, it would cost the same as a 28 MPG gas car at $1.89 a gallon.

    Around here, gas is averaging $2.52 today, while electricity averages 9 cents/kwh. That puts the Tesla on fuel-price par with a 75 mpg gasser.

    And unlike the oil that fuels my Prius, our electricity to fuel a Tesla doesn't help fund ISIS.

    But, in the Northeast, electric rates have climbed at least 30% - the reasons from National Grid, limited availability of natural gas supplies, so they hit the consumer with a rate increase.

    For me, charging once a week and gasing up every two weeks is more convenient than charging everyday and gasing up once a month (for reasons in post #1).

    The cost varies widely but on average, today's gas average is $2.15 and average electricity rate is 13 cents kWh.

    89 MPGe EV would cost the same as a 44 MPG gas car.

    Well to wheel emission is about the same for both (~250 gram/mile).

    The beauty of an EV is that it can run on pure solar as long as the owner does not sell SREC to recoupe on the cost of PV panels. Otherwise, it is $20k additional on top of the price of the car.

    The average price used to be 11 cents per kWh. Now, it is 13 cents. 18% increase.

    Almost all the states with top cleanest electricity are about 18 cents.

    PiP launch states are among top 13 cleanest in the US. It is clear Toyota's goal was to reduce emission using grid electricity. When mated with the 50 MPG gas engine, it is tough to beat in terms of cost to operate as well as emission. It doesn't make sense to release it in the state where EV miles emit more emission than gas miles.

    When gas prices go back up, you bet I will charge it up every opportunity I get. However, for now, I will save the wear on the battery.

    For me, it costs me approximately $1.10 in electricity to go as far as I could in our former Prius.
    Personally, I don't care if gas is free.
    On electric I have more convenient refueling.
    I keep my money for fuel local, helping the local economy and giving zero help to people that want to kill us.
    I have a vastly nicer driving experience. And I don't care if it is a Tesla, Leaf, or other EV, it is much more responsive, smooth and pleasant to drive.
    I am not contributing to local pollution as much, and don't have any concerns over warming up my car in a closed garage.

    Unless of course you care about reducing oil use too. In which case you won't want to use gas right?

    There are many important benefits aside from direct costs giving more reason to consider electricity over gasoline.

    I would add that continuing to charge helps take particulate and other pollution types out neighborhoods and cities providing significant health benefits.

    I am charging again. I paid $2.19 per gallon last fill up.

    I continue to charge. I paid $3.69 per gallon last fill up. It's now definitively less expensive to charge and use as much EV mileage as possible.

    Wonder if anyone has stopped charging their PIP. Gas prices are around $2.00 in NJ: Compare Side-by-Side
