    For me there are many factors...outside temp, acceleration, amount of regen ability. At first I was getting less than expected range, then slightly more. So far this summer, my expected range hovers between 35-37miles. Depending on how I drive, I usually come very close to it, but rarely over. And not by what you are getting. I am really curious when the fall and winter come how much range will decrease.

    my record is 36 miles on a full charge. average is prob about 30 miles. my odometer (10k miles) is 79mpg.

    i use the Prime for occasional around-the-city driving but mostly road-trips (~100 miles)

    I have only fully depleted the battery once or twice so far so I don't know the real EV range I'm getting. But most commutes are my 22 miles to work and the remaining miles generally shows ~10 miles remaining, so something closer to 32 miles if I were to guess.

    The mileage is an estimate based off your driving history and route. You can also have it show your battery percentage which is just the absolute remaining battery.

    Day 9: expected range = 32.2 (actual trip was 26 with 12 remaining = 38 miles EV).

    No AC on a 85 degree day, hilly PA roads. speed 45 to 55. I suspect my all-EV commute to work is slightly downhill overall. I cannot charge at work (yet), so I can't check the EV distance returning. I start HV mode when I leave work and then switch to EV once I am confident I can complete the journey on all battery.
    Avg mileage since purchase is around 200mpg.

    Is there a specific reason you start HV right away? You will have better overall fuel economy if you waited to let all the EV run out.

    Near 100° during the day with a 74° dew point and my EV mileage keeps creeping up by a tenth or so per day.

    Yesterday morning estimated 37.1 and I drove 41.1 actual EV miles. My best to date.

    Estimate range is still creeping up daily like I said above. It was 37.4 this morning but I "only" squeezed 40.2 miles out of it.

    Letting all the EV run out can be less efficient than starting HV right away at highway speeds and/or driving through hilly areas.

    I find on highway drives of over 30 miles, where I want to arrive at my destination with an empty battery, that it is more efficient to drain a few miles off of EV, then engage HV and get through the warm-up cycle. I will stay in HV until my destination is between 5 and 10 miles further away then my EV range (say 35 miles away when I have 28 miles of EV range left), then switch it into EV Auto. With the engine warmed up, HV Auto engages going up the steeper parts of hills, and I find better overall fuel economy. This spring, I regularly finished 50 mile drives with MPG readings between 160 and 199.9 using this method.

    On one of the forums here I read that it is better to have the engine warm up while still in EV mode. Otherwise the engine gets extremely poor mileage while it warms up, and additionally, it is under more strain while it is cool., which adds some stress to the engine. Added to this, within a mile of leaving work I have a long up hill of 2 miles at a fairly steep incline. I figure it best to have the engine warmed up before I get to the hill. Then the engine assists going up. That hill mostly kills what battery I have left for the trip home. Many miles later, if I have 2 miles left on my battery (for example), I turn off EV mode about 4miles home and try to get to the garage without the engine turning on. Usually I make it.
    This is only the second week I have owned the Prime, so I'm still learning what works best. And you could be right about just leaving it in EV all the time and let the engine kick in when if feels like it. I am open to other thoughts.

    Do you drive without AC?

    Mine seems to always get around 33-34 range, mostly without AC (though used it the other day in the extreme heat), city + freeway driving, keep my speeds moderate.

    I did until the temps got around 92° then I turned on the A/C about 10° cooler than the outside temps (full ECO everything).

    Today I've crept up to 37.9 miles. My actual was right at 40.9 miles EV only. My ECO scores are 99% almost every day. How high will it go . . . . .

    I got the car last September so this is my first summer to play.;)

    That's great. I've had my Prime just about one year, but so far I was able to complete my 36.3 miles commuting all on EV only twice last fall. If I had no other car following me, I might be able to get better range.

    That's good and doesn't that extra 8-10 miles of EV feel great. It's all about traffic, time of day, and route choice for me. I can work out the terrain challenges with technique, but that doesn't work on traffic.

    My point was...you had mentioned you usually arrive home with EV miles still left. I think you said that, correct? If not, apologies.

    But if so, it is definitely most efficient to make sure you have no EV range left when you get home.

    I usually start the engine when I have about .2-.5 left, depending on conditions. Then I switch it back to EV to let the warm up happen while I'm using the rest of my EV range. Otherwise in warmup it is using its HV reserve that it will have to replenish after the warm up cycle. Sounds like you have the right thinking though with what you are doing.

    Today I've crept up to 38.2 miles even with the recent 100° temps and A/C usage. I drove a bit over 40 miles actual. This surprised me with the heat.

    Is that 2042 miles on the present tank, or extended trip miles?

    That's great if you like to buy from and support companies that lobbied to block Tesla from selling direct to the public because and I quote, "The dealership sales model is in place to protect the consumer." Then when Musk released all of Tesla's software OPEN SOURCE AND 100% FREE, they took that source and threw together lower line vehicles and pretended they did the work themselves. They also filed for bankruptcy, took taxpayer money to pay off their debts and expenses, then went IPO but banned their IPO shares from being accessible to the same public that funded their bankruptcy and rebuild for 30 days.

    In fact, literally every single EV that has been released since 2014 pretty much only exists because of all of the work that Tesla put into the software engineering. The only companies that actually committed to environmentally friendly vehicles in any notable numbers are Honda, Toyota, and Tesla.

    Hydrogen fuel cell technology has been around for a very long time and while being the owner of a natural gas well myself I SHOULD be promoting them, it is still a vehicle design that requires you to stop and fill up frequently - and hydrogen filling stations aren't exactly common. I can't imagine that under any circumstances, this type of vehicle would be preferred over one that you can plug in in so many locations and especially AT HOME. If you ask me, vehicles powered via fuel cells are a step in the WRONG direction when compared to plug-in hybrids and EVs.

    It is also worth nothing that in my opinion, Green Car Journal is a paid for advertising site that shills whatever they're paid to support, and is pretty much run by a few bored guys out of a garage. It's not a respected or reliable magazine. In 12 years they haven't given any awards or respect to the 3 vehicles that pretty much changed the face of the low-impact automobiles -- Insight, Prius, and Model S.

    Can you reference any of these Fanboi / MuskBro statements?

    The 'patents' released where not worth anything. Look it up.

    Making a BEV is not Rocket Surgery.
    I'm certain my '14 BEV has zero T software/tech in it. And it's awesome !!

    Why did you list only two other PHEV/BEV manufacturers? Both of them are very late to the party in making such cars, did you know that?
    And some of their offerings are lame compared to long established PHEV/BEV manufactures.
    Have you actually looked at the numbers for the amount of cars produced?

    Yes, this is ONE continuous tank. Above (yesterday) mileage is 2042.6. This morning I started with the image below @ 2060.0 Note the gas gauge in each image is still above 1/4 tank. (My best, May 1st fill up was 2.272 miles on one tank.)

    It's not all EV either. Once a week like today, I have to drive 118 miles round trip. I can start on a full 38 - 40 mile charge but can only get about 15 miles of charge on the 1/2 way point. Plus I have a 550 mile once a month trip. All of that is in that 2060.0 miles @ 199 mpg +. I still hypermile the heck out of it when in HV mode. It works. :)
