Range, and how much do we need anyway?

  1. I'm definitely fairly range anxious. If I buy an Ioniq 5, it'll be my first ev (nevermind that the chances of my having the ability to charge at home are poor because of old condominium infrastructure). I've been following recent reviews and reports, and while the reviews are almost universally glowing, reports of range have me kinda concerned (specifically with behavior at highway speeds). (And of course under normal circumstances we shouldn't really go outside the ~10 or 20% to 80% range, for battery health)

    No question, the thing (and basically any modern EV) will do fantastically in city driving, but it looks like real world range at ~70mph for the top spec configurations will likely only be around 215 miles. I'm a pretty conservative driver myself, and I rarely exceed 65mph, but it *does* happen (and range at 65 probably won't be spectacular either). (Though it would probably be a few percent better if Hyundai or dealers allow it to be bought with the 19" wheels)

    Obviously, this is a byproduct of the I5's relatively poor drag coefficient, so it can't be helped (I'm really curious to see what the range of equivalent EV6 configurations will be. It looks like it's drag coefficient should be significantly lower). This leads me to thinking: How much range do I or any of us really need? I know full well that I'd only really need 200+ miles of real world range perhaps twice in a year, and that charging facilities will most likely be available on any route I'm likely to drive... but I can't help but feel like it's not enough. How do you all feel about relative range requirements (not just the plain rational math)?

    Here in the US the goodies they have been showing off come in the top trim I suspect which only comes with the biggest battery pack. So how much range isn't part of my buying decision here. Consult your own country specifications which haven't been released yet in the US but I suspect the technology pack, moving console, dual memory seats, V2L and heat pump will be only be available in the top trim. If so there will be a lot of complaining about that but if they don't like it give up the purchase to someone who won't and wait until they option it in a more diverse way in years to come. Range I suspect will come in around 300ish and price around $44.6Kish. Sad colors will be limited but I'm kind of glad this one has been held back and my opinion has changed on it. I just look at what is available and pick and forget what the world got that I can't have. That's what wrap is for but for me it'll PPF straight away. Large-45003-HyundaiIONIQ5RedefinesElectricMobilityLifestyle.jpg Love the color but not with the trim.
     
  5. I'm in CT, USA. I'm guessing most of us will want the top trim goodies. I just hope there will be a way to get hyundai or a dealership to provide it with the 19" wheels for an extra few % efficiency. I'd have liked red paint myself, not sure what I'll do on that account. What's PPF?

    There were some tests quoted in https://www.ioniqforum.com/threads/official-ioniq-5-wltp-ranges-and-consumptions.37093/page-2 which suggest a range in europe of somewhere in the 20X range at speeds around 70ish mph. The US will have a 77.4 kwh battery instead of a 72.6kwh battery. Assuming a linear relationship between battery capacity and range that would mean ~6.6% greater capacity. So somewhere in the ~21X range (though apparently at least some of those tests were done in normal, not eco mode, and with regen off).
     
  6. I’m also in CT. I had a 2019 Kona electric which just got bought back by Hyundai due to the battery issue. Haven’t fully decided on what will replace it, but the Ioniq 5 is on the short list.

    The efficiency on the Kona was excellent. In the summer, I would get an average range of 340 miles on a full charge with AC usage. It’s too bad that preliminary testing on the Ioniq 5 is less promising.

  8. FWIW, they're not comparable. The Kona is a size class smaller and a thousand poundsish lighter. But yeah, the I5's interesting styling probably doesn't do it any favors aerodynamically (and the tests I referred to were high speed highway driving). It'll be curious to see what the EV6's real world numbers look like, to see if it's comparatively smooth shape makes a difference.

    Also, the I5 is AWD, The kona seems to only have one motor? Correct me if I'm wrong. Isn't the Kona also rated for 258 EPA? The RWD I5 will do better than that (the question is, does anyone want the RWD version or is everyone into the toys)

    Honestly after about six months of driving an EV your range anxiety will go away, slowly. It's always something you think about, I find I look at range in the car all the time but when I drive a nice car I rarely notice the gas gauge. It's just part of the joy

  10. I have to sort out how I'll charge one first, but if that gets worked out, hopefully you're right :)

    (Re charging: I live in a condo complex. There's talk of EV charging, but it may be a while before anyone figures out how to retrofit the complex. My office only has a few charging ports, so my best bet would be DCFC a few miles away which is said to be bad for the battery, but nobody is quite clear on how bad. Some say catastrophic, some say I'd never notice)

    I currently own 2020 Kona Electric and also an Ioniq 5.

    Pretty happy with the efficiency of the Kona but you really cannot compare the two vehicles. The 5 is way larger, way heavier, more solid built, with larger tires and wheels and frontal area that’s larger and less efficient. Generally speaking the range of the I5 is 40-50km less than the Kona’s, but charging stops are oddly fast, so overall it’s a pretty good trade for traveling times.

    Wonderful to hear from an actual owner! Your information and opinions are greatly appreciated.

    RWD should more or less match the Kona if it’s with the 19s. It’s WLTP is 481km which is on par with the 2020 Kona with the Michelin Privacy tires. If range is the number one thing for you, probably that’s the configuration you should aim for.
     
  15. We'll have to see what the exact trims and options are in the US, but hopefully it'll be possible to get all configs with 19" wheels whether by option or by dealership. I was planning on AWD, myself (as I've had one too many close calls in winter weather), though I'd probably run in eco mode most of the time on the highway (except perhaps for moments where extra power would be needed). EPA range estimate for the top trim awd is 244 miles, I think (which is a combined number), though that's with 20" wheels.

    What config do you have / what kind of consumption have you seen at speed?

    PPF is an abbreviation for Paint Protection Film. At best it is a professionally applied clear durable film that is applied to vulnerable paint surfaces (sometimes all) to protect the paint from scratches. Some PPF’s with heat exposure self heal blemishes the film takes on instead of the paint. Think of it as a show room shine and protection for your car.

    There was a recent article that linked to a 2020 article that spoke of a mechanical disconnect to the front motor. It’ll be interesting to compare it to a RWD.

  18. As far as I understand, on AWD configs, whether or not the front motor is engaged (mechanically connected, I believe) is computer controlled and associated with drive mode:
    Eco: The front motor is never engaged
    Normal: The front motor is engaged when the computer determines you're asking for a lot of power/acceleration
    Sport: The front motor is always engaged

    Claimed range from hyundai for the RWD trims in the US is 300 miles, AWD for lower trims is 269 miles, AWD for the limited trim is 244 miles (this includes a switch to 20" wheels, and the addition of the panoramic roof). The nominal hit for AWD would thus be about 10%. Digging around on the ford configurator for the Mach E (since the ID.4 is not yet available AWD) the claimed ranges are also 300 and 270 miles, which would seem to suggest that the mechanical disconnector either doesn't have an efficiency benefit, or that I'm misinterpreting the numbers. These numbers are combined, of course. Highway values will be appreciably worse for all models (though the I5 seems to suffer worse, which concerns me)

    Bjorn Nyland has an Ioniq 5 range test (286 miles at 56 mph/180 miles at 75 mph) and feature demonstration video on YouTube. "Holy Macaroni" he says of the 205 kW charging rate.

  20. I
    I wonder what mode he was driving in (ie Eco, Normal, Sport) and how much of a difference each mode will have on range.

    You can see "Eco" on the dash, so he was using only the rear motor. Also, he had the increased-range benefit of 19" rims/tires vs the energy-gobbling 20-inchers.
     
  22. Yeah, I saw that. The charging rate is... first rate. The energy consumption figures leave much to be desired though. At low to moderate speed the thing is very efficient, but get up to higher highway speeds and it loses almost half it's range. That is extremely disconcerting (even though I rarely exceed 70mph)

    If somebody has an awd version, could they double-check if the motors graphic shows real temporary front traction in Normal mode as quoted above. I personally thought the disconnector could only be in awd mode (front pm motor mechanically geared to front wheel axle) after a Sport mode command. This peculiar way to use the awd seems to better match your description of Ioniq 5 Normal mode which prevents starting or on-demand awd in Normal
