    In winter if your journey is longer than 10 miles you should always start with gas. This means you can use the engine as a genuine CHP, providing both power and cabin heat. As long as you are not breaking excessively you won't have wasted much energy from not having the regen breaking. Once the cabin is nicely warm shut down the engine.

    As previous posters have said your journey type is important. So if you are starting on small roads and then going onto the freeway and you are prepared to endure the cold, then you could start on electric and move onto engine just before you join the the freeway and get the 'free' heat then.
    EV is best used on slower roads and stop start traffic as the Prius battery is so tiny.

    I've had my PIP for 4 years now, and it consistently gets about 7-8 miles on a full charge. That's mostly driving 25-35 MPH on side streets in hilly central San Diego.

    sounds right, if the hills are steep enough, depending on acceleration.

    After 3.5 years with the PiP I still get about 21 miles per charge, but I'm a hypermiler who mashes the EV button to stack miles and only use EV when traveling on level ground or downhill. My overall MPG per tank of gas usually hovers around 80 mpg.

    This means that 'one charge' for you is one plug-in charge + excessive intermediate charging due to the ICE.

    right, not meaningful in this discussion. a lot of people are confused by this.

    Yup, it's the continuous EV engine-never-starts drive that tells the aging story.

    Using the guess-o-meter to determine battery degradation is very inaccurate and misleading.

    A better approach would be to track the kWh for each full charge over time. A healthier battery will accept more charge, while a worn out battery will accept less.

    I'm not going to make any more posts saying how many EV miles I get because it isn't meaningful. I also toggle the EV / HV button to maximize EV range and fuel economy, so my EV range is much higher than most.

    Correct. If you don't do that you're just throwing that energy away, which would be intentionally reducing your EV miles per charge. I'm not sure why anyone would intentionally reduce the efficiency of their PiP.

    some of us don't drive far enough to use the ice on a regular basis.

    I've had my 2012 PIP advanced for just over a month. My drive to the office is 10.3 miles over varied up and down hills. I consistently make it to the office with about 1 mile of EV range left. Now, having said that, my charging and estimated EV range can vary. I've seen everything from 9-13 miles of available EV range when starting out, only to end up with that same 1 mile left, taking the same route every day.

    I've noticed something interesting since November 2015 when I bought my used 2012 PiP. In November, I was getting 10.5 miles estimated range after each charge. In the coldest part of winter, it was 9.5 miles. Now that it's brutally hot outside, it's back to 10.8.

    I'm not sure this means anything, except the range-o-meter might be taking outside ambient air temperature into account when estimating range... It doesn't seem to affect my actual range.

    agreed, i think it does. plus, your actual miles will be reduced less in the heat than the cold.

    Cold air is denser than hot air. It means that in winter the car has to work harder to push the air out of the way to go forward. Your EV mileage estimate doesn't take into account ambient air temperature. All it cares is that you had a full charge, and you were able to go X miles with a full charge. It keeps track of this over a long period of time and adjusts it's estimate based on your past usage. In the winter I typically see my range estimate drop to 10.3 (or a little less if we actually got rain for any amount of time). The EV estimate is currently sitting at 11.0 when I start out in the morning. By the middle of summer, it should be back up to 11.3. And by the time it's winter again, it'll be back down to 10.3. It's done this cycle for the 4+ years I've owned the car.

    Are you absolute certain of this? I have seen pretty big changes just day to day that happened to align with big temperature swings. Anecdotal, I know. But others have said similar things.

    For those who are getting 10+ miles: What kind of conditions are you driving in? Do you have a lot (or any) hills, heavy traffic, etc.?

    I'm consistently getting estimations of around 9.2 miles doing the same commute, and it seems quite accurate as I'm driving about 8.8 miles and may have 0.1-0.3 miles left when I return home. Here is an example of one my journeys: Garmin Connect

    There are a lot of hills, several traffic lights, and also many narrow streets where I often need to stop to allow oncoming traffic to pass. Do you think I'm getting normal battery performance considering these conditions?

    Stop-n-Go traffic kills any mileage regardless of energy source, because the power to overcome a dead stop will be quite a bit greater than the power regenerated back by the brake regen system, unless you are going down one heck of a long hill/mountain. My EV estimate ranged from 9.6 this winter to 12.0 the other day (11.9 this AM due to the cold front moving through yesterday). EV range is extremely affected by previous trip energy usage. For instance if I can keep the power bar on the EV screen at less than a third that'll help with estimation and range. But many times that isn't an option. Traffic demands typically override those options.

    Wow! Are you traveling a lot of highway speeds? I can routinely get 14+ if all the conditions are decent.

    at about 14 mile estimate right now. very flat here, most back road 30-40 mph driving. temps between 60 and 80 degrees recently.

    If in fact the EV mileage estimate took ambient air temperature into consideration then if you drove home at 75 degrees and had, say 8 miles remaining and woke up and it was 40 degrees you wouldn't see 8 or 7.9 miles but something like 6 or 7 miles. And the reverse would happen if the car was charged and it was cold, later in the day when it was warm and you hadn't driven anywhere you'd see a big jump up in estimated mileage.

    In 4 years time you'd think at least one person would have reported this phenomena, right?
