    New to the Clarity. Got one for the motor pool.

    I can see the display that shows EV vs ICE range remaining, the display that shows instantaneous MPG, MPG for current trip.

    But I'm looking for breakdown of EV/ICE miles for each trip and for total vehicle miles.

    (Coming from Ford CMax Energi PHEV, familiar with their displays).

    There is no breakdown sadly. If you use ECON mode and HV off you'll use EV only 99% of the time (unless you floor it and engage the gas).

    I don't reset Range A so that it keeps total miles. Then on info screen you can select current trip and then Range A tab. If it shows 199 mpg, then you know you are running about 80% EV or better if ICE mpg is 40 mpg (40*5=200). If it is less than 199 mpg, then you can estimate with a little more accuracy. I also just keep up with all gasoline receipts and write down on a piece of paper in the glovebox all the gallons of gasoline purchased and the miles on the car at the time of purchase. So far I have purchased 20 gallons of gas and have about 3/4 full tank of gasoline now. I bought the car with a full tank of gas, so I have burned about 22 gallons so far. I have 3800 miles on the car so that is about 172 mpg (range A shows 179 mpg). I've averaged at least 45 mpg on gas so that is 990 miles on gas and 2810 miles on battery (approximately). Hope that helps....

    I often whine on this forum that I would pay hundreds of dollars for a software patch that added a mega-information screen option for the center display. EV miles and ICE miles per trip, per defined interval, and lifetime are near the top of my list of specifications for my mega-info screen.

    I concur. I have a 2012 Volt and the amount of information available still isn't enough, but it is so much more than on the 2018 Clarity... so aggravating.

    This is ... pretty pathetic. Why they had to go to all the trouble of making this car... and miss this basic fact.

    I'm the sustainability manager of my org. I went with the Clarity for the simplicity for new EV drivers. Going to be a PITA to try to collect this data.

    I think Honda decided to gear the car towards a typical driver, rather than a tech savvy driver. I wish they made the info available through custom screens on infotainment. They totally fail to utilize that center screen, so much stuff you could do with it.

    Exactly. They wanted a vehicle that would be familiar and comfortable for people who are used to traditional gas-powered cars. And they did a good job of that, including things like making it creep when you put it in gear, and making the brakes work exactly like people are used to while still reclaiming as much energy as possible. But I do wish that they had provided more visibility into the internals of how the car works, both in terms of reporting real-time data and documentation. People who don't care about that aspect can easily ignore it.

    If you're coming from a Ford PHEV, you'll be used to lots more information than what the Clarity has to offer. Our Fusion Energi had abundant info available for those that desired it and Ford figure out that lots of folks who buy PHEVs want that info!

    not just yeah but hell ya.
    I'd like to see a per charge trip as well and a recording of how many kWh per charge go into it it and a mpge and mi/kwh. I would also like to be able to log gas purchases directly into the car and have it send me weekly/monthly/yearly reports. you could also log cost of fuel fill or your contract rate for electricity if you have flat rate or bill from public charger. one more thing is logging of how much energy is going to climate control the car and lighting etc. I also want a toggle for the electric heat as well (like the a/c toggle) since heat isn't free here. I'd also like an indicator when the ac and heat is on.

    If it had all my wants I'd kick $350-$450 to Honda for that in my current car. If there is a second generation of the car I hope that add this stuff.

    I would particularly like charging info. When I charge at home I have the info from my Kill-a-Watt look-a-like so I can reimburse the condo association for the electricity, but when I am out and charge for free at my local coop, there is no meter. When I charged at my cousin's they had no meter. Many free charging stations have no meters or are just plugs. Here at my daughter's there is no meter. So aside from a SWAG, I don't know anything on my recent long trip except how much gas I put in.

    It's wonderful how data is available only when money changes hands.

    Not as nice a solution as having the car tell you, but there are devices that can provide that information, at least for level-1 charging. For example,
    This device goes between the charger and the wall plug and measures voltage, current, and power. Note that I am not endorsing this particular device, although I did buy one and it works as advertised.

    To make this even more frustrating, there is not an engineer on this planet who wouldn't design the logging of EV vs. ICE into the vehicle computer. Most importantly, the knowledge of ICE usage should factor directly into the service intervals (but it doesn't seem to, per much discussion elsewhere in the forum). One of the most relevant threads on bogus oil change interval is HERE.

    Still, I am willing to bet that there is a TON of diagnostic information available that just hasn't been exposed in the user interface. Options for additional information include the Hidden Diagnostic Menu HERE, Honda's HDS tool, What may be available through the ODB 2 interface, etc.

    I think KentuckyKen has even gone so far as to install an hour meter on the ICE (I love the ingenuity) !

    Until a better way is discovered, I plan to track every drop of gas, and every kWh of electricity I use (My L2 charger logs kWh). That way, the mileage breakdown would be something similar to this:

    EV miles ~= Total kWh * 3.25 [basis: 31 kWh per 100 miles]
    ICE Miles ~= Total Gallons * 45 [basis: 45 MPG when running on gas]

    This can be compared to total miles on the odometer as a sanity check, and maybe these approximations can be refined a little.

    My numbers (so far) :
    Odometer = 1093
    EV = 293 kWh * 3.25 = 953 miles
    ICE = 4.2 gal * 45 = 189 miles (8 bars remaining out of 20 on 1st tank of gas)

    I am happy with this correlation so far with very early experience.
    I plan to connect to the OBD2 just to see what comes out, but without additional technical details, I am pessimistic about getting additional useful information directly from the vehicle.

    It would be nice to have the option of more information. As others have said Honda seems to have been making a car that just functions at a high efficiency level with little extra driver input. A car for normal drivers to get in and go. You even say you chose it for it's simplicity, little strange to then complain it isn't more complicated.

    I managed to nab an eMotorWerks JuicePlug from eBay a while ago. I really wish they would be made readily available.

    Since I have to reimburse my condo association for the Level 1 electricity in our common garage I have had to use a meter between the wall plug and the Level 1 cord. I bought the first one, a Kill-a-Watt, at the end of 2012 for my Prius Plugin, but it did not retain the info after power outages and did not survive the removal of the charging plug. I replaced it in 2014 with this one which is still going which is still working just fine for my Clarity and has never lost any data.

    The problem is not at home. It is when traveling and charging at a house without a meter or at a free Level 2 station with no meter like our local coop. It makes it impossible to do anything but a SWAG.

    Given that you know the percent of the battery you've just replenished, it's a bit more than a SWAG. But you're right that it sure would be nice if the car would simply keep track of it. I expect that the data already exists but we just can't access it.
  21. I’ve also started tracking this with a sheet (and will put an old kill-a-watt 15a I have in the charger bag). I’m lucky on that my work charger displays the kWh (and they likely log it since I need an access card to charge).

    I’m sure the data is in there somewhere. Would love to track the trip economy data and correlate with route, strategy etc.

    Loving the car so far (two weeks). We’ll see how I feel after it snows (coming from almost 20 years of Subaru).

    If you're in snow country, I believe snow tires on FWD beats AWD w/o snow tires--especially because snow tires use all 4 wheels to enhance stopping. Of course, AWD with snow tires reigns.

    Interestingly, there's now an AWD Prius, but it downgrades the normal Li-Ion battery to an NiMH battery.
  23. I'm in NYC and rarely have to go out--I'm a professor, so my work actually closes when there's a significant snowfall. My entire route to work is on high capacity roads that are plowed/salted first. Had I really been in snow country, I would have bought another Subaru (or maybe a mild AWD, like the RAV4 hybrid).
