    I've been reading a few adds and articles but still can't fine this info:

    Is the Prime a 3 Season EV?


    The way the PiP was?
    No cabin heat when operating as an EV?

    Prius Prime comes with a vapor-injected heat-pump.

    That's the most efficient electric-warming available for any EV currently on the market.

    The engine will start itself when the air is below +14F or when windshield defogging is requested.

    I test drove my new Prime yesterday, was ready to bring it home, and the dealership had a paperwork snafu. I'll get it Friday. I took home the 780 page owners manual for study...it needs some serious editing. 784 pages, actually, and some in Japanenglish. I've read and reread the 21 pages of section 2-1 on hybrid operation, and I still can't find the difference between EV and EV Auto modes, as one example.

    Drove very well. Good acceleration, smooth transition from gas to electric to gas as the situation demanded. The dealership didn't charge the battery. Comfy seating. The ride was a bit harsh, but maybe the tires were overinflated with the pure nitrogen the stealership failed to get me to pay for.

    They probably just wanted to keep it a few days to look it over or show other customers. Perhaps you will get a kick back.

    I couldn't find the answer in this link. I scanned Danny's large description post but didn't have this info...
    So, I googled it!
    Top result: Advanced Heat Pump Comes of Age in the New Prius Prime. Would this be a good option for Model 3 or the Bolt EV??

    It is a “vapor injected” heat pump.

    It sounds like awesome future leaning technology!
    This statement is important from that article:

    Stepping back, one has to ask: Why is Toyota going to all this additional complexity for a low AER plug in vehicle that has a gasoline engine? There’s plenty of waste heat available from the engine. This complex of a system would be better suited for a pure BEV in our opinion. Perhaps Toyota DOES have a secret BEV project waiting in the wings and the Mirai is just a ruse!

    Sounds like the Prime is a legitimate 4 Season PHEV!
    But I think this article said the engine starts if defrost is selected.

    Very good! A work around to only use the high tech heat pump and keep the gasser asleep.:D

    With this new EV functionality, is the Oil Change Monitor updated, or is it still a simple odometer timer?
    It would be a shame to change oil with ~50 miles on it every 10k miles.

    I have a child in SAN asking me to help her buy an EV. I'm trying to get facts.

    you should join in on the existing owners threads. there are only a few so far, but detailed questions are only answerable by experience, and they are happy to check things out for us.

    AFAIK, it's still a fixed OCI.

    Besides, that engine would've been in there for one whole year. (if you don't hit the 10,000 mile interval first) so it'll be prudent to change it anyway.

    i wonder about this as well. i only put 4,500 miles a year in hv mode. some people think once a year minimum is important, but i wonder if testing would bring different results.

    Exactly. What if you only racked up <500 miles a year on the oil?
    $50 for supplies plus any labor is a waste of time and money to change immaculate oil.

    Another well know PHEV uses the 2 yr mark for oil changes on unused engine oil.

    I thought the Prius did away with the volt like erdtt garbage but sounds like it's instead on steroids.
    Too bad.

    In 3-5 years when I own a prime I will have to trick the ambient temperature sensor so I can run gas free at 15 below like I do in the volt.

    it has been stated that condensation is a reason to change the oil once a year, but i don't know if it has been proven. also, the filter should be fine, or could it dry up and plug up from non use?

    Does the Prime have 2 counters ?
    One for miles in HV and one just for the miles covered by pure EV-Mode ?

    One reason to change your oil even if you don't use the engine much is that some of the oil additive package is volatile and will go away over time.

    One of my friends is a serious car guy (like, he works as an engineer on professional racing teams). He had an old Chevy that had about three oil changes in its 200,000+ mile lifetime, the first of which was at 83,000 miles.

    I asked him about it. He said he changed the filter every 5,000 miles or so, and replaced the lost oil (about a quart). Doing that replaced some of the additive package and kept the oil clean. Since the car lasted well over 200,000 miles, I guess that worked.
