I can really confirm this. My 2018 Ioniq Classic has now covered 160,000 kilometers and its range still feels as far as it was at the beginning. That's why I've kept this car and will continue to drive it for many years. I've also sold my 13-year-old diesel and have now equipped myself with an Ioniq 5 Long Range. Thus, I have completely switched our household to electric vehicles.
I think a lot of these car batteries will do the mileage. What will be most interesting is to see how time affects degradation, since charging and discharging seems negligible if done within certain parameters. A 6 year old Ionic is holding up well, but I wonder what a 10 or 15 year old one will be like.
Oh yeah, the classic Ioniq. That is the car that convinced me of EVs and I am now driving the Ioniq 6.
Great to see that you still do videos in 2024 about Ioniq classic! Best greetings from Germany
Very nice. Hyundai should bring this exact design back and place a larger battery in. They could offer 40 and 60 kwh options and sell it for cheap given that it requires no new engineering. We need less self driving and laser lights and more affordable, reliable options! Call it just Ioniq and sell it!
Coincidentally I just released the results for a study of degradation on 20x Ioniq 28kWh this morning too. These have anywhere between 40k and 160k km on the odometer. Many of the contributors to this crowdsourced exercise will have been inspired by this channel to buy the Ioniq classic in the first place. And yes impressive results on the degradation but also very consistent across that sample, which is great!
If only I knew of your crowdsourced test, as before battery replacement my Ioniq 28kWh at 145k km was at 33% degradation. I still have the proof if you would like.
Lmao! Calling something with a sample size of a whole 20 cars a "study"! Ahhahahhahah
Also 160tkm on the odometer is classified as 'everything necessary should be completely functional' in used ICE standards by consumer protection laws in my country. Only well after 200tkm should there be major issues expected, so your "study" is useless for a normal consumer looking into longevity of a used EV.
@@Tsimi1234 glad it made you laugh, i see twenty being better than a sample of one or two and a starting point for more. In fact we've now doubled the sample to 40 (wow!!) and participants remain welcome.
@@evdabbler I have one with over 190k km.
i really hope someone finally builds a car like this again. with todays battery prices it would be incredibly affordable and we have enough suvs... we need this type of car. not another eQ 999 X8 EXTREME
Hello from Denmark, my Ioniq classik, from 2018 has 197500 km, hav not notist anny dikredation, stil going strong.
Testing and road trips in older EVs like this is, in my view, some of your most important work. The Sun has left the chat!
Please make a episode about fixing motor bearing in ioniq, it's common problem for ioniq and Kona
Bought the original 2017 28 kWh used with 35k miles. I now have 115k miles. Don't know degradation, but still get around 100 miles of real-world range. Likely could get 120 miles, but I don't drive it down that low. Love the car. Unassuming vehicle but nice power and a smooth ride.
The beginnning! My first electric car. A masterpiece in its time.would still be long range king with a modern battery.
It still is the efficiency king.
I have one and it is great but please do remember it is really efficient due to the fact that it has a small battery. If it had to drag around an extra 30kwh, I do not think that it would be efficient like we know it
@@elvisd8832nope. We could now fit more than 40-50kWh in there with (around) the same weight. Also, I've transported hundreds of kgs with the OG ioniq, and it remains just as efficient.
I own a 2018 Ioniq with 200k on the ODO. I never calculated degradation but I easily get 150 in winter and 200 in summer. If you want to borrow mine for a test, let me know!
There are Ioniqs with 300,000+ in Germany.
Are they being used as taxis? I heard there were early Ioniq used as taxis in Netherlands for sure and I have also seen some in Spain
@@kiae-nirodiariesencore4270 Maybe, but not the car I know. There is a video with title 250.000 Kilometer mit dem Elektroauto: HYUNDAI-Fahrer rechnet schonungslos mit Elektromobilität ab!
That car reached 300.000 km meanwhile and it's not a negative video as the title might indicate.
@@kiae-nirodiariesencore4270 a friend of mine has 5 of these cars and they reached 250.000 km without any problems.
Classic Ioniq aka the Wind Knife…. If only they keep making these and put a better battery for longer range… I’ve never heard a bad word or review acrosss many reviewers on these cars..
Classic Ioniq, I insta click! :)
I confirm this data, my classic Ioniq has now 6 years and 8 months, and about 162.000km. Last summer I did a degradation test and I calculated about 4% degradation, this summer I will redo the test. My ranges is almost the same as new
Last Februari I drove my ioniq 28 150km in with 2% left go at 164wh/km mine has 43000km on the clock.
This means almost no degradation in capacity.
At 2% fast charging started at 62kw.
Did a degradation test this weekend on my 2018 IONIQ that has 210,000km. (Drove her down to 3%). Calculated degradation was 8.5%. Pretty dang good!
Glad to see this Bjørn, gives me confidence to hang on to our ultimately quite low mileage 2020 Ioniq 38kWh as long as we can. Such lovely car, our first ev, couldnt bare to drive anything else and not see the low miles per killowatt hour! Rarely get less than 5m/kWh even in winter, now the weather is warming over here in southern uk we're back up to over 6m/kWh. Sorry I cant do the conversion and that would be my request for your videos, as you're such a number Ninja could you do the conversion when you tell us of consumption? I'm number blind and Wh/100km does not compute in my poor old brain! Cheers Bjørn, i dont comment often but love your videos my friend. 👍👏
In Germany we usually use kWh/100km for ev consumption. Björn prefers Wh/km.
If your Ioniq consumes 10kWh/100km then it's 10.000Wh/100km which equals to
100Wh/km, a real good number. My brother's first ev was a classic Ioniq and his car only needed around 10kWh/100km (or 100Wh/km).
Your Ioniq drives around 6m/kWh which converts to 6x1,60934=9,66km/kWh (rounded). If you devide 100 by this number: 100/9,66=10,4 (rounded) you'll get the number of 10,4kWh/100km or 104Wh/km for your Ioniq classic with 6m/kWh milage.
@@yt-viewerfromger320oh bless you and thank you, that's very kind of you to put it down so clearly for me.
I have a 2017 28kWh Ioniq with 210k km, still works great! Showing 200-210km fully charged and fast-charges perfectly 👌
Only annoyance is some small creeking from the back suspension, but that feels expected with the milage
My IONIQ just passed 210,000km and I did a degradation test. Drove her down to 3%. Calculated degradation is 8.5%. Enough for 230 km of range in the summer and 175 km in the winter (Vancouver, BC, Canada)
We have this car here in Ireland. Bought it in 2018 and drove it in Ireland, UK and France. Barely a moment’s trouble with it. It has about 145k kms on it now, and we haven’t noticed any real drop-off in available range (we’re not paying close attention, but it gets all the way to the chargers that we use when travelling to Dublin and all the way home just as in the early days, so it seems fine). Except for the battery, the car is out of warranty, but we’ve only been stung with one repair, a tyre-speed sensor for €400 IIRC.
Interested to see if this good performance by Hyundai carries over to the Ioniq 5. Getting a high mileage one shouldn’t be too far away given they are coming up on three years since release.
I miss my classic Ioniq, should not have upgraded.
Wow the owner relly did not take good care of seats and steering wheel. Such a shame because the Ioniq is a great car.
Interior degradation is bigger issue in this one 😁
That's the power of cobalt we see here. I think the battery uses NMC111 cells.
ev-database says: NCM622
@@sandmehlig It's sad, that these older batteries with NMC622 chemistry are better in terms of coldgating and degradation than the currently manufactured NMC811.
@@sandmehlig I don't think this is correct because for the 38kWh version it also lists a NMC622 chemistry. And other sources claim the 28 kWh version is NMC111. But I haven't found a definite answer.
It's not just cell chemistry. Manufacturers are more tailoring the cells to their (auto motive) needs now, which can also mean to have a specific target of cycles they should live through (and not too many more) - - > cost optimisation
@@EinzigfreierNameI agree. It's definitely closer to 111 than 622. Mine had around 2400 cycles and lots of DC fast charging when I sold it. It none the less had single digit degradation. Balance was still perfect and it charged faster than almost all current EVs, even when the battery was very cold.
The Unicorn of classic EV...
Nothing wrong with the car, but there is somting wrong with previus owners 😂
I have one of those... Just 108K km and still going strong. No need to sell it out swap it...
It's time to test the E-golf (35,8 kWh battery). It has a different battery chemistry/producer (Samsung SDI) than the smaller battery (Sanyo/Panasonic)
Great video! And so nice to see how well Ioniq age.👍💪
Hi Bjorn i have Renault Kangoo Z.E. 33kwh 2018, 271k km, soh 95% 😎
My Ioniq 38 kWh, four years old, 55.000 km, is still at 100 %.
That's Hyundai's SOH figure. Not related to degradation, but cell balance
Great test, find one with more miles down the road👍🇸🇪
Degradation tests are the best thing, to see how older cars are in fact, and confirm/debunk myths about older EVs and which ones in particular.
Nobody but Bjørn mentions the problem of the motor/reduction gear noise (helicopter noise I think) and how Valdemar solved it.
It is a plague in many of Hyundai/Kia released from 2017-22. Anyone?
Nobody? I know of workshops in the Netherlands, Germany, Hungary and Croatia who can fix this issue. The bearing on the motor needs to be replaced. There is no replacement part from Hyundai, but you can use some adapter to use a standard bearing without issues.
@@lucas7793 I know two here in Spain that do the same thing, but people wonder if that solution is durable, and why Hyundai/Kia don't do it
@@Patrobasket There are no replacement parts from Hyundai. Hyundai only replaces the whole electric motor for about 10k€. Replacement should probably last as long as the original. There seems to be an issue with some current going through that bearing and breaking it after some time. Some people say using Sport mode will break it faster. Tesla used to have the same problem in the first generations. They "fixed it" by using non-conductive ceramic bearings.
@@lucas7793 I agree with you in all you are saying and heard the same from others. They are trying like Tesla did it, but cannot be sure yet that the problem doesn't repeat itself. So if you're out of guarantee, changing those bearings is not very different in the long run, and much cheaper.
I have 2019 28kWh Ioniq and somehow it was the exception. At 143,000km the batteey was already degraded to only holding about 16.5kWh (66%), confirmed with multiple degradation test using your method.
The problem is that SOH% on these cars is completely inaccurate to capacity, even with such severe degradation, SOH was still reporting 84%, and so it was extremely difficult to get Hyundai to honor their 70% capacity warranty. Ended up being a one year long fight.
Overall the batteries in these cars are extremely reliable, but buyers should just beware that in the rare bad luck case, the fake SOH may allow Hyundai to try and scam you out of warranty coverage.
I am sorry to hear that. I would instantly go to court if Hyundai would try that on me. Calculating remaining capacity with the Ioniq 28 is almost hilariously simple, so no discussion needed. I have to believe in any litigation made up fairytale SOH number the car reports itself must be absolutely worthless. Imagine manufacturers of other product types would try this! Or even cars... imagine the 300 kW sports car only produces 100 kW on the dyno. Who in their right mind would argue that the internal system of the car reports 300 kW so it must the correct?
The SOH is not necessarily fake - SOH has nothing to do with kWh. Per the most common definition, SOH is Ah/Ah_new.
It is simply the wrong metric to use for a guarantee, because the driver doesn't care about SOH.
I assume you checked cell voltages at low SOC - were there bad cells?
@@w0ttheh3ll no, it is not. It is not other EVs like Leaf. SOH on these early Korean EVs is just a calculation based on cell balance/voltage deviation. A heavily but evenly degraded pack will still show good SOH.
@@TehOnlyAnd1-pw8ci not that were noticeable. It was a heavily degraded pack but quite evenly so, hence why SOH was still high. See my above comment for explanation.
2021 38kw premium 75,000 km 0.3% deg. 318km range :D
@bjornnyland do you know anything about ICE degradation? This efficiency loss over distance driven seems to be exclusively discussed in the context of fully electric cars, but I've been wondering how much ICE cars are affected due to wear and tear of internal components. We know they sometimes lose a significant amount of HP during their lifetime so I'm pretty sure efficiency loss could be an issue as well.
I've been searching the web for answers but I can't seem to find any significant data, or even any data, regarding the matter. It would be very informative to have a comparison of identical ICE car couples with 100.000 km difference on the odometer tested for range per liter of fuel. Let's say two 4 cylinder and two 8 cylinder petrol cars of different car brands, just to have some real life benchmark to compare fully electric cars to your real life EV test benchmarks.
Your 1000km test format could be a very doable way to retrieve that kind of real life information. Maybe in a combined effort with another tester, so it would be possible to drive the younger and older car in the same weather conditions. Maybe some testers would be interested in finding out, or maybe some have already done that and my Google Fu is lacking?
Cobalt for the win.
We have a 2017 ioniq 147,000 km on the clock only 3.7% degradation. Based in Ireland.
Only problem is Hyundai Ireland them self's. Warranty isn't worth the paper it's written on. 2.5 years waiting on warranty parts. Yes you did read that right. Really bad.
Now I live in South Korea and often see Ionic 5 and Ionic 6.
6 Ionic looks like a Porsche and often these models work in taxis
Our Ioniq Electric 28 kWh has rolled 170 tkm and has a SOH of 94 % and also the interior is way tidier than the one in this video for instance the steering wheel is almost like new.
Too bad we live so far apart, I have a Zoe 52kW which has done 110,000km now. When I bought it, it had 23000km on the odo. Have only charged to 70-80% and run it down to 28-38%. But have commuted approx. 225km weekly and then charged it to 100% and driven down to 5% on average. Would have been interesting to see how degradation is.
@bjorn: can you please explain how you get or calculate the cycles number in your degradation google sheet?
In this test you state 1620 cycles which results in 100 km/cycle (with odo 162.000km and calculating odo/cycle to get km/cycle). In your other 3 classic ionq degradation tests you calculate with 160km/cycle. Sounds inconsistent to me, but i do not know how you get the cycles number.
same remark, there is an obvious mistake.
I recalculated % dregradation per cycle to be 6,8%, and not 4.3 (per 1k cycle) for this ioniq. Would be appreciated to know more about usage of this car.
Thank you. I made a mistake but it has been corrected. The Ioniq still gets very high up on the list there. It was just moved down 1 position.
I wonder how the car calculates the state of charge, because at 3:37 at 338 Volts it shows a charge level of 44% and at 4:08 at almost the same voltage of 338V it shows 24% state of charge.
Resting voltage. As it drives it dips. When it stays it goes up. Bms is smart otherwise your state of charge would go all over every second while you're driving if it relied solely on pack voltage.
@@ramunasgudauskas7582 I assumed that each percentage of charge corresponded to a certain voltage level. So I still don't know on what basis the BMS determines the actual state of charge if not by voltage.
@@pavelblaha5243 The BMS likely does two things to do that: it does coulomb counting (integrates the current over time to come up with an Ah differential), and it guesstimates the internal resistance of the battery and uses that to compensate for the present load which allows it to estimate the resting voltage if load was taken off from the battery.
162k km = 162 Mm. Megameter ftw.
Exactly. I don't understand why people are so bad at language and understanding the metric system.
In German car forums, it's even worse.
Great video Bjorn! Is it the case that the Ioniq gets better with age based on your results then?
Having had the ev 2019 for about half a year now. I am pleased to have it confirmed (again) that all the time and research watching the user market (Finn.no) and weighing the pros and cons of the electric cars I was considering. This one not only ticked the things I needed (+ some of the things I wanted), battery life was one of them as I plan on driving this car for a long time to come. Takk igjen.
Do we know why Hyundai have non-linear battery displays?
Because it's easier to calculate (lazy engineering) 😅
It's proportional to battery voltage.
@@gerbre1 rather propotional to electric charge (i.e. Ah) remaining in the battery however without taking into consideration the dropping voltage (that's why it's non-linear). Anyway taking electric charge is far more accurate way of calculating SOC than voltage only (that would result in SOC jumping up/down like crazy)
@@ArturFliesNot really either proportional to Ah. It's more a bit of a mystery why and how it works exactly. It certainly doesn't make sense.
Is it the same Engine in the kona?
I own a ioniq 2020 what's a big 38 kilowatt battery I would be surprised to know how much decorations does those cars have when they have over 200,000 km
It had 28 kWh net battery capacity when new, not 26 !
Incorrect. It was never 28 kWh. That's only according to spec. Actual tests shows 26 kWh.
Measuring SOH on these cars is really hard and requires more driving and proper charging.
I myself have Ioniq 28kWh with 41k ODO and when I bought it, it had 100% SOH. Now after 5000 kilometers I did not do full discharge and charge to 100% and it showed me 89% SOH. It was able to use only 22,5kWh from the battery. After lots of hours reading discussions and threads on forums regarding battery degradation of these cars, I am performing battery calibration test (slow discharge and slow charge to 100% several times), and it is slowly getting back to 100% SOH. Last time I was even able to measure getting 28kWh to the battery pack (excluding 11% losses on AC charging).
You can't trust the SoH variable in Korean cars.
@@bjornnyland Thats right. But also measuring kWh and degradation based on battery percentage used, consumption and kilometers driven can be misleading until you are totally sure that car is giving you whole capacity it has. In my case it gave me less available capacity until I calibrated it (although it COULD store more). You can rely on your results if you know that the car was regularly charged to 100% and discharged to 7 or less percent once in a while. There is a chance that this car can give more and the degradation is actually lower.
I am not trying to disregard your results by all means. I am only sharing my observations from my particular use case.
Thanks Bjorn for answer :)
how about the air conditioner ? is it reliable ?
Ioniq is the king 👑
Distorsion from microphone, defective?
Whats up with the sound, some kind of distortion or maybe to high volume output?
Read the subtitle at 0:15.
My 2018 Ionic goes same way as new. Actually I don't know better and more efficient EV. This winter in -15 I tested MB, MG and others. My Ionic use 15 kWh/100km, others in same route +30 kWh/100km. New car seems to be shittier.
Funny because you can’t set a charge limit on 28kWh Ioniqs either. 100% or nothing! And the battery doesn’t care!
Except when DC fast charging. Then it automaticaly stops at 94 % ;)
Wouldn’t that be a great car for you to buy Bjorn??
Why do you think I like nasty beaten down interior?
@@bjornnyland No, not because of the condition... but the model is someone you often speak highly of.
Only the motor and transmission was replace 🤣
Not good
And the replacement of both does not solve the problem in the long run, some owners have experienced...
There is no "k km". It's Megameters, Mm or 10^6m.
Germans are equally bad at understanding the metric system and language, often I see "tkm", even mixing two different verbal prefixes for the same thing.
