    (pasted to the wrong forum, repast it here)
    Though the winter here is not too cold, still very happy.
    Actually it shows 52.0 miles in the front panel.

    Lucky you. I am getting about 33-35 miles up here in snow country. Might be months before I see the EV miles go over 40 again.

    AC settings? Seat warmer? Precondition?

    Not enabled any of them.
    Otherwise can only get 40 miles.

    It's just a kind of test, I just wanted to see how much the battery can perform in Dec.

    Thinking about postings from those getting in the 50s in winter and upper 60s in summer: for those of us getting in the mid-30s now (or only in the high-50s in warm weather), should we be concerned . . . or, at least, asking the dealer if there's a software update or part to check?

    I’m only getting a range of about 35 in temps in the 30s. In the summer we’d get as high as 55. So the Clarity (at least our Clarity) takes a huge range hit in cold weather.

    How anyone got a range of high 60s, in any weather, is beyond me, unless they do a lot of downhill driving. ;)

    Those numbers are achievable if you don't turn on the heat at all. I wasn't using the heat even though with temps in the 20/30s. The EV range indicator was 58 miles the last time I charged to full (I typically charge to 80% as recommended by other EV manufacturers like Tesla). I'm able to avoid using the resistive heater most days because my garage is heated and insulated so the battery and cabin are modestly warm when I start out (about 55 degrees). Also, my driving is mostly in town so speeds are low. My typical 16.5 loop uses 19% of the battery in the summer and 23% currently (w/o heat). With the heater on lightly, it's well over 30%. If you set the cabin temp to 68 degrees or higher, you'll have very low EV range, especially if you drive at highway speeds. That's just the nature of these vehicles.

    Simon (OP) could you say where you are, or temperature ranges where you are? I'm curious what your current lows and high temperatures are?

    I thought I had read someone that had tested out his range with & without heat and found a difference of only about 1-2 miles. But honestly, I'll be damned if I'm going to freeze my butt off for a bit of additional range. We buy nice cars to be comfortable and driving in the winter without heat is not my cup of tea.

    Caveat that my personal experience is still very limited (it's only been a couple of weeks that it's been below 60 in the AM lol) but it seems to me the fact that it's colder outside is not as important to the estimate as I was led to believe. So far, what's affecting my range (both estimated, and actual) is what I'm using while on my daily (same route, routine etc) commute, including: windshield defogger, AC (and how strong it is) etc. That said, the difference from my experience so far is more than 1 - 2 miles; more like 5 - 10 miles (and that's on a 30 mile round trip commute lol) Worse experience so far was leaving the windshield defogger on through an entire 12 mile drive (and it wsn't even raining the entire time, I just forgot) and I basically used up 2x my normal energy usage for that leg of my commute. By the time I got home, my battery was at 37% when normally it's closer to 55%

    Us Kens think alike on this. I was willing to not use the heat to see how much I could stretch my range. That worked with preconditioning and seat heater while the temps were low 40s. But now it’s cabin heat and to h**l with the range and MPGe!

    Watching the range go down with cold weather is like watching your retirement investments every single day. It will give you ulcers and a heart attack. I’m saying no to the stress and yes to the heat.

    BTW, I’ve seen the EV range estimate go from mid 60s in summer to now low 50s at 40 F. That’s local driving under 60 mph, driver only, no big hills, with AC and then seat heater and not factoring in preconditioning. Actual range is usually 10 to 15% less but I hardly ever drive over 30 m in one day.
    And I’ve only pumped 14 gal of gas for the whole year so no complaints.
    Absolutely the BEST CAR EVER for the money and for what was available at the time I bought it.

    About 40 to 52 recent days

    I’m absolutely stuck on 35-36 regardless of the type of driving. We drive conservatively, no jack-rabbit starts, so I’m resigned to these numbers until the spring.

    Of more immediate concern is the low pressure tire warning we got yesterday. All tires showed about 36, until I got to the last one on the drive’s side rear...10lbs. :(

    So this morning we’re out to a tire repair shop we trust for a fix that can hopefully be made. We’ve already had to replace one tire. I wonder if these OEM Michelins are more prone to road hazards?

    When the temperature reaches 40°F here, people will be walking around in shorts. My EV range has fallen into the 20s and I don't expect it to change much for the next three months. But I concur with your feelings on using heat; I did not buy this car to be uncomfortable. Luckily I can still accomplish my local errands with the reduced EV range.

    Is "MPGe" your invention or is this a unit of measure that's formally defined somewhere?

    It’s actually an EPA invention and is listed on the Mulroney sticker which says our EPA cost estimates are based on 15,000 miles/yr, $2.40/gal, $0.13/kw, and 31kW/100miles. So the EPA lists the Clarity at 110 MPGe combined city/highway with the best midsize car getting 136 MPGe.
    The calculations are all at fueleconomy.gov. Which also lets you calculate personalized estimates (using you particular cost of gas and electricity) and compare vehicles.

    @bpratt posted this a while back:
    The government defines MPGe as:
    (Miles driven / KWh used) * 33.7
    So my best MPGe is 38.4 miles / 8.97 KWh * 33.7 = 144.267 MPGe

    I also calculate MPGe based on the cost of gas.
    Miles per KWh * (price per gallon of gas / cost of power per KWh)
    So when I got the 144.27 MPGe, the cost of gas was $3.18.
    The cost of my power is $0.0963 and I got 4.28 miles per Kmh
    4.28 * (3.18 / .0963) = 141.333 real MPGe based on cost of gas

    Merry Christmas!

    Your temps are about same as mine-- I'm in Eugene, OR. My range lately has been about 30-32 miles.
