New Nissan Leaf vs Hyundai Ioniq road trip

[@MPU777]

This the real deal. Individual comparisons are cool, but head to head is the king. Thumbs up, will be awaiting for more of these.

[@esunisen3862]

Dude, Ioniq is red, that's why it's faster, you should have known this.

[@dennisaskeland5870]

leaf got krumped!

[@renebergqvist599]

Hi Bjørn, 2 possible reasons. The temperature dependance can have a fairly sharp impact. In addition it has a heat blanket (Nordic and CND versions) that is probably on - even when you stop. The Leaf pack is probably constructed to be more exposed to the chill factor (motorway increases chill factor drastically) as it relies on passive cooling (in the summer) - ioniqs battery pack can be insulated better because it has active cooling and will self heat easier and loose less heat on the motorway.

[@hollymolly518]

hope he see this, this is probably the different between passive and active cooling

[@hollymolly518]

those are stock tire right? so...it shouldn't change tho, cause it mean you'll spend extra money on leaf, but if you're testing i guess we could change it and see how much it's gonna change tho

[@kennethmclean872]

This videos among your others is one reason a went out and brought a classic 2019 ioniq. Love the car amd love your enthusiasm too

[@DarcersTech]

Am waiting for Hyundai to release the 40 and 60 kWh versions of the IONIQ. If the 40 is not much more expensive than the current one, it will be a game changer.

[@AgentSmith911]

Darcer's Tech When does the 60 kWh come out?

[@DarcersTech]

If I remember correctly, Hyundai promised "sometime in 2018". It is most likely going to be the same powertrain as the Hyundai Kona and will be probably implemented into the upcoming KIA Niro EV as well.

[@DarcersTech]

Source? Because I think you are not quite right: insideevs.com/200-mile-hyundai-ioniq-electric-coming-in-2018/

[@gregandkaruna6674]

Xkraft I never thought the Ioniq was a very good investment it's 28kwh battery was just too small and the price was not good at least here in NZ starting at $60k!, but the new Kona with its 40kwh base battery size will be the ideal price to range.

[@tubetop123]

Whao what the heck happened! LOL

[@bartsmakman4501]

I drove the new Leaf in the Netherlands in higher temps (5 degrees C) and had 17,7 kWh/100 km. Same average speed as in the video (68 km/h): at 37:52 minutes the drive computer shows 20,8 kWh/100km with an average speed of 68 km/h.

[@juharommi3302]

I have Nissan Leaf 40Kwh 2020 and I like it! I haven't any problems. Good FAMILY car. Range is enough for me. No chargingproblem anyway yet.

[@Nicelemons77]

Brother from another mother

[@TheJanicetunes]

I love all of your driving test. They are the best in the world! and really help me decide on my next ev. Thanks Bjorn please don't stop doing these test drives.

[@DumfriesDik]

I have really enjoyed your video's on the Leaf and Ioniq. Many thanks for doing them, I really enjoy your style.

[@20cent22]

Thank you Bjorn for this excellent test! Your real driving test are all that a potential buyer needs to know! I have a Leaf 30Kw and temperatures below -10°C are very limiting for long trips. It seems that this aspect has not been greatly improved with the new generation.

[@bjornnyland]

Check out my new video coming out soon.

[@Alex-rq4iw]

Great video Björn, exactly the kind of video i was looking for. Looking for a electric car but havent decided yet. Leaning toward ioniq after this video.

[@jimwhitehead1532]

Thanks for testing this in subzero weather. Battery losing power like this in subzero weather is dangerous in places like the US where you can get stranded in the middle of nowhere. A few weeks ago I just bought a 2013 Leaf. My trip showed 13 miles to spare to get me to the next dealership in Virginia, East Coast US. People didn't believe me, when I told them the temperature suddenly plunged 20 degrees at midnight to subzero (F) and the car range dropped over 10 miles in just a minute. The car stranded me in the lane on busy Route 1 and didn't even tell me to pull over, because the 12v died at same time. I had to get a flatbed to tow it to recharge and get an expensive hotel. That Leaf was returned to the dealership the next day, to exchange for a 2013 Prius at the same cost ($10K US). I hope to get a good used Model X in a few years as my ultimate car.

[@agent00klc]

Ioniq with 64kWh battery will be the best buy (I'm hoping for Kona battery).

[@peterwaller]

Predrag Bela yes. Join the queue.

[@Cosmycal]

Not sure, we will have to wait to compare with the 60kWh Leaf.

[@ferrarista27]

That will never happen with the current chassis. The kona has a new chassis with flat style battery. For that to happen they will have to use the kona chassis. Current ioniq is built on regular chassis for regular ice engine for hybrid and plug in hybrid.

[@sth128]

Actually as an Ioniq driver, I believe kona has a better drive train and efficiency. Kona does 470km on 64kWh where as Ioniq does 200km on 28kWh. That means 13.6kWh/100km for Kona and 14kWh/100km for Ioniq. Given that Kona isn't as aerodynamic as the Ioniq, it definitely is more efficient. Also in my experience winter driving in Ioniq nets you the EPA rating of 14kWh/100km. In Summer it's closer to 10kWh/100km, which push the range up to almost 250km.

[@Crosshead1]

It’s disappointing considering the Ioniq was designed from the outset to be an electric car, albeit with a Hybrid and Plug-in Hybrid version, while the Kona us essentially an ICE vehicle converted to run as an EV. You’d have hoped that Hyundai would have designed the Ioniq fir easy update to a more powerful battery pack. I really don’t like SUV/CUV type vehicles (I really don’t see the point of them or what people see in them, regardless of their power source) but I guess I’m bucking the trend. They all just look so utterly boring and lacking in any sort of style. Hmm! Guess I just answered my own question.

[@bonham1981]

Fantastic video, I love these IRL comparisons. Even if they don't cover every little aspect, they help to form a better opinion than most dedicated reviews. Thumbs up from Germany. PS: I love the Ioniq more and more.

[@mhaddadi]

My ioniq in -15c used 15kwh/100km. In 0c it go down to 10/100 Canada.

[@4yourgarden]

Cannot wait for kona great video and look forward to retest in warmer weather

[@RadoTrenciansky]

It's nice to see you used Veefil Tritium to charge that Nissan Leaf Bjorn. Those fast DC chargers are made here in Brisbane, Australia. :)

[@SURFpal]

I guess Leafs and ionics will occupy those 1x2 CCS chargers mostly all the time and jaguars will stand in line to see Teslas pass by.

[@florinhantig829]

Nice race :) more of this pleas :)

[@pdken3081]

Great test guys, keep it up. You are doing us all a service.

[@mruifer]

Ioniq 28kw is enough car for most of people, why waiting. Best car for real good price. Don’t wait for better car in the next time.

[@justjc51]

Will be interesting to see if the switch to LG Chem for the 2019 LEAF, the battery producer for the IONIQ, will make a big difference in colder weather.

[@jay.atkinson]

Thanks Bjorn, great comparison video. Request for a banana box challenge between the LEAF 2.0 and Ioniq please.

[@TeamYankee2]

Regarding the backup camers and the 360 view - the edges are visible on a model without ProPark... the blended edges are a different camera system with a wider view for the ProPark system.

[@bjornnyland]

Thanks for the info :)

[@TeamYankee2]

Bjørn Nyland keep up the good work. Totally love tour videos.

[@marktiller1383]

City use with an ioniq in a warm climate, 246-265km. Outside the city, without continuous red lights , 280km at a guess as I've never tried it. I have seen outrageous early morning figure, which are unbelievable, you get them and then yet another red light. One day , I'll have to give it a try, but it's just a nice comfortable car to take me and my family wherever.

[@dominicmiqueleiz165]

Always fun, but more importantly an excellent summary and great comparison!

[@automatix5]

When you're charging the Ioniq with heating, you should put in the parking brake, because then the headlights turn off.

[@palgjervan1424]

Nice tip, thanks. I always turn off the lights.

[@joshsouthwaikato6543]

wolpertinger42 . I have an Ioniq in NZ. It is great, there is a mix of free chargers and paid chargers. The paid chargers are about $5us for 80% charge. I live in a town, and it’s really the wife’s car. It easily lasts all week as a town shopping cart. We trickle charge only (12 - 20 hours) only as we only own that charger. Yes a bigger battery would be a bit more convenient but we can travel 500 km with 4 stops to the destination. This can be a pain, or I see it as a break, it makes those journeys more enjoyable having 2 extra stops to stretch and eat. In nz we ran out of Ioniqs for sale. I recommend it to any town or city dweller.

[@sergeyyevtukh388]

The hump in the middle of a floor in Nissan Leaf contains buttery disconnect for emergencies.

[@hypnosemesmer7000]

Super tests really great thank you

[@williamlabarre4755]

With LeafSpy you can also see the Aux and Heat power demand detail. For Heat, it uses Heat Pump for a bit on the downward temperature conditions, then it switches to Resistance Heat, which is least efficient battery use.

[@Peter-st1lt]

Thanks Bjorn another great test! It was fun to see somebody else on a test with you. Unfortunately it looks very discouraging for the leaf, living in Canada those performance issues will be a big problem not to mention how the battery behaved if you can't depend on the battery state of charge meter then what can you depend on.

[@0Nick0]

It's shocking that a 28kw/h battery can beat a 40kw/h. I guess thermal management is very important.

[@simoncanfer5030]

The aero advantage of the Ioniq is huge, that's the main reason they use similar percentage of battery per mile. Leaf just can't rapid charge more than once, which makes the Ioniq effectively faster over long distances.

[@ivangoubarevpascual4301]

Spoiler alert!

[@93AR155V6]

But the battery sizes is not 28 vs 40kWh. The Ioniq has 28kWh useable energy and the Leaf has a total battery size of 40kWh. So the Ioniq battery is more like 31,5kWh and the Leafs useable energy is maybe 34-36kWh. So 28 vs 34-36 or 31,5 vs 40, choose whatever.

[@Trades46]

Nothing to do with Thermal management. Easiest way to warm a cold battery is do what Bjorn likes doing - drive like you stole the car. The real reason why is most of the test is done at freeway speeds from 90km/h~120km/h where the aerodynamic design of the Ioniq trumped the Leaf. TMS only becomes an issue when constantly DC charging in hot temperatures - honestly the focus on TMS-bashing is such an overblown issue against Nissan.

[@wedrive-derblogfurelektrom2899]

28 kWh is net capacity of IONIQ Electric ;) 40 kWh is not even gross of Leaf (net 36-37 kWh).

[@toostrong2209]

That's a pretty bad attestation for the Leaf. Bigger Battery and still faster loosing energy in percentage. Even with faster speed: that's no excuse.

[@sjefern]

Great video! I was hoping and waiting for this one. I am happy i went for the Ioniq. I belive the faster charging and longer/more or less similar range in cold weather makes up for the better autopilot and parking cameras. I altso dont quite agree in what you say about boot space. As you can lay the ioniq backseats basically flat (wich you cant do with the leaf), it makes it so much easier to load larger loads or more suitcases in the ioniq.

[@KTPurdy]

Interesting trip. For the Leaf I would have appreciated it if you would have tracked the battery's temperature with LeafSpy. All of that DC charging in one day probably raised the battery temperature by the end of the trip which would have explained better range towards the end of the trip.

[@johnd1561]

This comparison was made with the leaf driving in b mode on the highway. While b mode enables more regen, it also creates more electric induced drag at highway speeds. You can get the same amount of regen driving in d mode by lightly applying the brakes. D mode allows much better coasting which would improve efficiency at highway speeds. Try this same comparison again driving the leaf in d mode, and see what happens!

[@princeding2114]

The hump at the rear has a relay switch under it. Only half of the battery is connected when car is off. They have the same thing on the old Leaf.

[@misc8867]

Awesome drive, exactly what i waned to see between these 2 cars. I went Ioniq since i needed a car fast, cant say i regret it. The only thing i miss is a dedicated app for controlling the car and seeing the charge and stuff like that.

[@VesoljeNet]

Almost certainly the battery heater was running in the background for at least part of the trip, since the temperature was between -14° and -19°C. Here is an excerpt from the Canadian Leaf 2018 User's Manual describing the battery heater: "The Li-ion battery warmer helps to prevent the Li-ion battery from freezing and helps to prevent significant reductions in the Li-ion battery output when the temperature is cold. The Li-ion battery warmer automatically turns on when the Li-ion battery temperature is approximately -1°F (-17°C) or colder. The Li-ion battery warmer automatically turns off when the Li-ion battery temperature is approximately 14°F (-10°C) or higher. The Li-ion battery warmer uses electrical power from an external source when a charger is connected to the vehicle. The Li-ion battery warmer uses electrical power from the Li-ion battery when the charger is not connected to the vehicle." Additional notes from the Manual about the battery heater: "- Vehicle driving range is reduced if the Li-ion battery warmer operates (Li-ion battery temperature approximately -1°F (-17°C) or colder) while driving the vehicle. You may need to charge the Li-ion battery sooner than in warmer temperatures. - The Li-ion battery requires more time to charge when the Li-ion battery warmer operates. - The predicted charging time displayed on the meter and navigation system (if so equipped) increases when the Li-ion battery warmer operates"

[@ianmathieson65]

VesoljeNet: To me, that pretty much explains the difference between the two cars in this particular test. As Bjorn stated, the temperatures were exceptionally low so in normal temperatures, the Leaf’s larger battery will provide greater range as is already well known from other tests and it should be the winner.

[@Cosmycal]

This is pretty much what happened here, with warmer temps the 40kWh Leaf should go longer and with other situations a lot longer than the Ioniq.

[@VesoljeNet]

Yes, that's probably true for _extreme winter_ drivers. But there is also a video on KZbin with Leaf 2018 being driven at 90 km/h in Russia at -30°C and getting about 160 km of range! (from 100% to 0%).

[@VesoljeNet]

Here is the test at -30°C in Russia: kzbin.info/www/bejne/sJ2XeWeQa5KYZpo

[@batraxos2]

I don't think that is what happened. The battery temperature is not the same as the outside temperature. The battery temperature was average according to the battery measurement in the car and should not need to be heated.

[@IDrAstiic]

If ioniq gets a 64kw battery like kona then its an instant buy for me

[@bjornnyland]

*kWh

[@IDrAstiic]

Bjørn Nyland thank you good man 👍

[@Crosshead1]

Join the queue.

[@pierremorant8885]

Hi Bjorn, many thanks again for this great video. I had a chance to test-drive the Leaf 2018. It is obviously more modern and more dynamic than the Ioniq, and the infotainment is better. But Ioniq outperforms otherwise. Even the trunk is nice in the Ioniq even if smaller, as almost perfectly square. And the central rear-thing in the Leaf makes it a pure 4-seater. So I join you on comments for life on board. I find it pretty amazing and very disappointing that the Leaf performs so poorly under low temperatures, in particular as it's supposed to be modern. My own short consumption test didn't show a drastic Fall at 90 or 100, so I presume cold Is simply poorly handled by Leaf 2018. Same test under 10 or 15 degrees, and the 30% more capacity will certainly give Leaf the victory. Greetings from the french riviera

[@EVPuzzle]

I'm thinking Ioniq too. can't believe it's beaten the new Leaf. I'll either wait for new Ioniq or buy bargain 2nd hand one

[@kasmopaya2676]

If the 64kWh pack comes this year, it will be a game changer.

[@alanmeschino7133]

Good critique

[@marktiller1383]

What a fantastic car , Hyundai have made, praise where praise due.

[@brianmagnussen903]

Great test toms op. Getting my polar white ioniq ev, in 5-6 weeks. :-)

[@sigitpermadi6037]

I like leaf design

[@Cosmycal]

This was a bad case scenario for the leaf, worse aerodynamics a bit worse than the Ioniq and colder air, electric motor working near max speed, 17" inch wheels with no aero, battery heater of the leaf working to maintain battery warm and still cooling on the motorway due to passive cooling design, etc. That's why Ioniq won in this test. The new Leaf can go a lot farther than the Ioniq in different conditions. Also the 60kWh New Leaf variant with the active temperature management system and hopefully with a more higher end speed motor should do better in this bad extreme conditions for it.

[@Azuriak3]

Add to that Pro Pilot which he had activated the whole trip i bet all those sensores and computing add to the battery drain

[@Azuriak3]

Moto Z Play Everything takes away from range, radio headlights heater etc etc... If you watch this video kzbin.info/www/bejne/mpO0hICpq7OjfsU you can see what Bjorn did to maximize range, he turned off everything!

[@bjornnyland]

Yes, but those electronics probably consumed some 50-100 W. That's nothing compared to 10-20 kW for propulsion and heater. But on my battery challenge, I didn't have to worry about heater or dense air and uphills.

[@bjornnyland]

Did you watch the whole video? On the return, we cruised at 90 km/h. I wouldn't call that "working near max speed". I have some new findings in a new video coming soon. Based on what I see there, Leaf would make about 150 km in those cold temperatures.

[@pete9b]

Great video Bjørn. 👏🏻

[@awo1fman]

I prefer analog speedo. Digital is much harder to drive smoothly because you can't see trend and fractions of units.

[@raptorpome2577]

Automatic cruise control

[@awo1fman]

All cruise controls are "automatic". Did you mean adaptive cruise control? Not that it's relevant anyway, because the whole point of cruise control is to not have to watch your speedometer, and I was obviously referring to those times when for whatever reason you're driving manually.

[@electriccarstv]

Ioniq top auto

[@benjanos]

Hey I love the reviews from Björn, no one else does this stuff. Has there ever been anything on the BMW i3?

[@rbbartho1]

When it comes to range, aerodynamic drag is a huge factor at higher speeds. So the sleeker the car design, the better the range.

[@Kristianpont]

Also think the efficiency of the cabin heater and differences in the thermal insulation of the cabin could be a factor at -16C. Would be interesting with a retest in warmer conditions.

[@colonelcarrillo3695]

do a video about maintenance of elbil and how to charge propely.

[@mrgurulittle7000]

Leaf is very reliable! I recommend a lot!!

[@BillyNoMates1974]

good comparison

[@claeswikstrom7086]

I have seen a significant difference with my current Leaf (2015) when temp is lower than -6 to -8C. Below that I really loose range. It feels like its like an iPhone dying in cold wx. When I depart with the car from my garage (+16C) it copes way better even though outside temp is lower than -8C

[@volkhen0]

I think the air drag is bigger on Leaf. It is higher so it has bigger front area which is one of major factor. The rear of ioniq is also more aerodynamic.

[@ivangoubarevpascual4301]

Maybe that hump in the back seats of the new Nissan Leaf is because the Leaf shares platform with the new Micra? They look almost identical on the outside.

[@juamiso]

Missing Thermal Management on the Leaf is killing it in deep winter. some cells will get warm while driving , but the ones exposed to the wind will be still very cold. So for the BMS it is as if the battery as a whole would be too cold to fast charge and the energy output is lower too

[@kasmopaya2676]

Could explain the jumpy battery %. Pack was designed to passive cool with the wind. Could harm the battery over time. Not good at all, we have to wait a couple of years if the harsh long winter of Norway harms the battery because of uneven heat.

[@Sneaker_Net]

Thanks, I really enjoyed this video!

[@Stoic-of-Rome]

Usually a battery that charges fast also discharges fast/wont hold a charge! This could be due to the cold temperature.

[@nothomeuser]

Besides the better aerodynamics of the Hyundai Ioniq, another feature that might have helped was the 16" wheels. According to WLTP the Nissan Leaf could get more 15km in combined driving just by using the 16" wheels. So that could have helped to increase Leaf's range.

[@randallscott-key802]

Bjorn I think you missed it on the Ioniq trunk space. I had an Ioniq Hybrid I traded in on my Kona electric. The Ioniq has a removable tray under the rear deck lid much like the Kona with a very deep well if you remove the sub-tray.

[@steptoe5519]

Richard Kilibreaux possibly that extra space is consumed by the Electric’s Bigger Battery?

[@happydaydreamer1]

I'm so happy I chose the Ioniq and not the leaf :) Great refined car, almost premium feel and excellent efficiency. The only drawback is the rolling noise on winter tires. Have not tested the summer tires yet, hope they are more silent but doubt it. Also I actually think the trunk space is way better on the Ioniq. The Leaf has these narrow "legs" around the wheel arches that steal a LOT of space and it looks even more shallow than the Ioniq. Drove Stavanger - Hovden this winter with tons of luggage and three people and coming from an estate version of Avensis this car actually works really well. Note that the middle seat does NOT have skibag hatch, bummer!

[@vatossureno]

How long is the charge time ?

[@Halfgaar1]

More vids with Alain! His laugh is starting me to laugh too! Nice comparison! Can't wait till you do a test with the Kona. About charging, the Teslas supercharger network is beter with more spots available and better charging speeds!

[@iZeroIX]

Vidioot thank you. It was a pleasure working with Bjørn :)

[@paulsingh7276]

18:00 "Mans not hot!" LMFAO

[@michachojnowski9004]

LIKE I SAID . It's not new Leaf its face lift. Even bigger battery pack don't change too much. Then you know guys why press test was in Tenerife. If will be somewhere in Europe or Norway it's will be total disasters. Leaf is good car but not for that money. If you don't need motorways speeds and road trips buy 30kWh leaf for 40% less price. It's better deal or used Ioniq

[@ERBE911]

Wrong, it’s a perfect car for Norway, where i live its almost never under 5 degrees cold and the Leaf is pushing 200km under these conditions! Like other test also have shown! We are seeing consumptions beyond 1,8 and with 38 kw available the math is simple!

[@michachojnowski9004]

ERBE911 Yours math is wrong when consumption is high. In Norway the speed limits help leaf. I'm owner of Leaf 24kWh and 30 kWh and know this car like a own pocket. If You cruise 80km/h consumption is low. But speed up for 100km/h or 110 Leaf eat own battery pack like duck bread. Car with this battery pack it will be universal car for long trips too. Did You see Bjorn movie from road trip with 30kWh Leaf? If not look it and learn. Temperature of battery was horrible. In new Leaf will be the same. It's good car for city driving not for long trips. If Ioniq will have 36 kWh or 40kWh I will buy one.

[@Cosmycal]

The 60kWh Leaf surely is perfectly suitable for long trips, the 40kWh one is more for mixed driving.

[@michachojnowski9004]

Girahim Yes , right it's good car for mix travels, but Hyundai go further than Nissan. Big battery pack it's weight , and heavy car must be better design for efficiency like Tesla. All body is made from aluminum. Bolt/Ampera-e have lot components from that metal. Engineer's must know 3 important things: 1) efficiency 2) fast charging from DC (like IONIQ) and AC for Europe 11kw is minimum from 3phase. 3) active thermal management for battery. Think what happens when DC charger was not used from that lady:) I don't drive Ioniq yet. I must do home work form that point.

[@Cosmycal]

The Leaf isn't that much heavier in comparison, it's efficient enough at medium and low engine speeds (obviously), DC and AC charging is very good for it's intended use purpose. You can drive the Leaf for 200/300Km in it's intended use scenarios with no problem. This variant simply isn't the best choice for this particular scenario, in my case I live in Gran Canaria (same weather as Tenerife) and I know the Leaf will perform better than the Ioniq in mixed driving here.

[@libertymurf281]

Bjorn ❤ PLEASE add 🔥Year, 🔥Model, & 🔥The Specific Version of Car Tested to the title of each video!!! Especially add all specific info in the descriptions!!! 👍Thanks Bjorn

[@artokiiskinen1058]

Blinker fluid? Is that a thing? I think BWM and Audi have very small capacity for blinker fluid... the cars seem to be constantly out.

[@Jelitek13]

I start to doubt if ordering new Leaf was a good idea. I have recently read two opinions where users said that New Leaf cant stand more than one fast charging. First one is fast and each next is much slower. I have watched the video and didnt notice that problem was mentioned. So I would be thankful if someone could confirm or deny that Leaf has problems with more than sone consecutive fastcharging during long trips?

[@bjornnyland]

It can take several fast charging sessions. You just have to be careful and don't hammer it.

[@Jelitek13]

Bjørn Nyland thank you very much for fast answer. 👏

[@mattaut88]

i just saw a rant from a 40kWh Leaf owner stating that LEAF cannot fast charge after ~2 rapid chargings. kzbin.info/www/bejne/joDKooBunqenhq8

[@Jelitek13]

Matthias Fritz yes I have seen it already

[@decimal1815]

Love the Ionic but don't like that rear view window. Would be using the camera and sensors all the time..

[@micheals1992]

You're forgetting to mention a bigger battery with have a longer service life, it will cycle less for the same total distance travelled. In the old leaf you might lose 20% capacity after 60,000 miles, the new leaf under the same use may only lose 10% capacity

[@princeding2114]

I am in Canada, you truly terrified me about the Leaf's thermal management. The heat loss happens due to the passive cooling and larger area to volume ratio for prismatic cells.(cylindrical cells can hold heat better)

[@bjornnyland]

I found out more about that. New video coming soon. Stay tuned.

[@SoUdNoGoR]

Higher Energy density cells just have the tradeoff of less efficiency (higher inner resistance), especially in cold temperatures and under higher loads. The cells have a nice capacity under testing conditions and on the paper, but immense problems in real world driving!! So better focus on a battery with a nice, low inner resistance at low temperatures...

[@tony6838]

Well, you should redo the test in summer time with AC off. The Leaf could let more fresh air in than the Ioniq hence need more energy to heat the fresh air which is -10 degree. This could mean, Ioniq's longer range could base on a unsafe base due to the driver could miss O2.

[@gregoryosullivan]

Ioniq Cd is 0.24, less frontal area than Leaf too. Not too surprised it did better at high speeds. Ioniq has a less powerful possibly more efficient motor as well

[@micheals1992]

I'm hoping that in 3-4 years you'll be able to pick one of these put for less then £7000 with over 100 miles range left in the battery. The old leaf is in this price range at that age but the battery degradation of those models means it's unsuitable for my needs

[@lotsofbumper76]

Great video 👍🏽 rather chuffed I chose an Ioniq (even if I have had to wait 6mnths) , will be interested in a warm weather retest. I wonder if Hyundai even need to increase the battery size for UK market. Once people adjust to driving shorter distances and slower speeds it’s actually a much more pleasant experience commuting

[@lotsofbumper76]

As a side note still infuriating no app for the Ioniq

[@DanLMH]

Bigger battery is always nice! I'd love an Ioniq but the range doesn't fit into my daily drive milage of 155miles a day. :(

[@lotsofbumper76]

Dan that’s a shame. Just outside of your range. Unless you could charge on route

[@claeswikstrom7086]

Some strange things with the Leaf battery presentation as you say but just by measuring the drag there is a 20% difference in drag. Just by checking the car cross section and the drag coeff there is a big diff. I quickly checked and internet states 0.24 on the Ioniq and 0.28 on the Leaf. Cross section is bigger as well. Skipping the comparison, high speed is not good for EV. Going 120 instead of 80 will double the drag.

Cd is one thing. What matters is CdA. I'm pretty sure frontal area of Leaf is greater than Ioniq.

[@claeswikstrom7086]

Bjørn Nyland Yes. In basic calc I did I checked the hight and width of both cars. Even if the Leaf has the same shape as the Ioniq it still is bigger

[@batandball617]

I disagree with your assertion that the Ionic is getting be an old design. The Leaf 40kwh is a face lift of the 2010 vehicle with some technical updates. This makes the 1.5 year old Ionic design much fresher by comparison. Ionic 40kwh has been announced for next year so given the Ionics more efficient drive train and aerodynamics it should easily trump the Leaf 40 for distance at least. I have driven Leaf since 2013 and I have loved my 24kwh, 30kwh and finally 40kwh versions. Having now taken delivery of a Kona 64kwh I can see how Hyundai have moved forward in so many ways. Thank you for your excellent channel and great no BS reviews.

[@batandball617]

Yes, it’s KWh, thank you for correcting that omission.👍

Koreans have an advantage, because everything is done in Korea. The Japanese have a battery for Nissan, American-made and, accordingly, Americans can adjust the price of a Nissan car, so that it does not compete with American cars.

Always good to watch this channel for range tests because the weather is invariably bloody terrible, so you get real world, worst case ranges, rather than stupid WLTP fantasy.

The Ioniq is mega efficient, but as I saw from sitting in both cars I found the Hyundai to be amazingly cheap inside. Yes the Leaf also has mainly plastics but the quality feels higher than the Ioniq which has a nasty hollow feel to it. Also the Ioniq with its slippery shape & kammback (read Prius) shape makes it better to cross-country highway trek than the more traditional hatchback shaped Leaf. This is does not however detract that the Ioniq is an amazing car in its own right, but the TMS-bashing & less efficient Leaf still has a massive advantage in mixed driving where the Ioniq's aerodynamics plays less of a role & actual battery size is significantly smaller. If Hyundai only puts a bigger battery in the Ioniq & Leaf gets TMS...oh wait, both are getting that in 2019.

Hello old friend, I watched this video with interest as I do with all your you tube entries. This particular one, the comparison of the Ioniq and the 2018 Leaf. Raised a few questions in my mind while watching it. The main items are the battery capacity Ioniq has a 28kWh against the considerably heaver 40kWh for the Leaf, you kept relating to the percentage of battery as the Leaf has only around 36kWh usable content and I believe the Ioniq has approximately 25kWh, therefore 50% of 25kWh is 12.5kWh but 50% of the Leaf 36kWh is18kWh therefore some 5.5kWh more taking longer to charge. It would be more meaningful comparing kWh used and replenished The use of the available battery is used by the two different vehicles in slightly different ways and had you used the available eco button on the Leaf with the 147bhp motor the use on the motor way and high speed section would have been considerably less with very little notice of slightly reduced acceleration against the Ioniq which has a very clever and secretive system which controls the power balanced to the demand by the 117bhp drive system this means economy. I noticed you had the E pedal turned off on the Leaf so you had very little or no re-gen going in to the battery. but as the paddle control system on the Ioniq gives an always low but increasing re-gen how much was put back into the Ioniq battery. While investigating the above details I found that the Ioniq battery will be larger for the 2018 it was intended to be 43kWh which has been developed for the new Kona but has now been found not to fit in the available space in the Ioniq and maybe around 40kWh. Finally the kerbside weight variation of the two vehicles has a fair amount of effect on power use and therefore capable distance. I missed not having your Sunday road trip to watch this week so found time to do this. Keep up the good entertainment.

[@bjornnyland]

You should split the text into paragraphs. Makes it easier to read. Ioniq has 28 kWh available, not 25 kWh. And I used eco mode. You should watch the video again.

I hope EVs someday start using E85/E100 heaters for battery etc instead. Could save a lot of battery? I know Volvo did this but it's not a common EV.

[@bjornnyland]

Not much to gain. It will increase range by 10-20 %.

[@simoncanfer5030]

Nice. It would be fun if next time you allowed the cars to depart when they're ready after charging, then the result would be how long the journey took. Maybe allow the drivers to choose their own strategy. How would a Leaf 30 compare to these two over a long distance?!

[@williamlawrence1019]

The Ioniq is more efficient. Therefore the faster you drive the more advantage the Ioniq has.

[@mistermister2085]

Test should be redone in warmer conditions. Then you could know if temperature was a strong factor (cooling the battery too much?)

[@batraxos2]

I decided not to order the new Leaf 40 based on this test and also another test performed in Norway. People on elbilforum.no in Norway have also not been able to drive 150 km on motorway with this car at 110 km/h. It also charges slow when you are on trips. I don't see enough advantage over my 2015 24 kWh Leaf to buy this car. What I need is a car that I can follow the traffic with on motorways even during the winter. You cannot do this with the new Leaf, you have to drive slow. Even on a 150 km trip in winter I most likely will need to stop once to charge here in Norway, like with my old car. The interior is made smaller with leg space cramped in the front, the armrest is now very small and don't reach my elbow anymore and the room below it is much smaller. I don't sit as comfortable in the seats as I do in my car, even though they look the same. I love the speedometer in the old car where I can see the speed and the road at the same time. In the new car it is analog old-fashion and you have to really take your eyes from the road and look to see it. The suspension is firmer and less comfortable. I was not able to test the motorway consumption myself as I was only allowed to test drive the car from Nissan for 30 minutes. Noise wise I didn't hear that the new car was more silent, my "old" one is also very quiet. I'll wait for the 60 kWh version, and if it doesn't show up like the Nissan salesman said that "nothing is confirmed about a 60 kWh version", I'll buy a different brand that has one.

[@bjornnyland]

Not many EVs in that price range can do 150 km at 110 km/h. I recently tested Ioniq (video not out yet), and it could do 140 km at 110 km/h.

[@billhopen]

did you have youe LEAF heater on, while he was being stoic, freezing in order to coderve electrons

[@kardy12]

It’s surprising that Nissan hasn’t introduced a thermal management system even in the new higher capacity 2019 model that is supposedly capable of charging at 100kW, as that will generate a lot more heat...

[@evtrekker1317]

Invite Alain back sometime for EV tests.

[@advitagrawal8851]

Hey Bjorn, really like and appreciate all your video.. but especially the MG ZS EV ones.. can you plan a race between that and Hyundai Kona?

[@montepaso]

I is not clear what batteries we are talking about here is ti Ioniq 28kwh vs Leaf 30kwh? Would be great to kwh in title like other videos.

[@JPSG3]

Try to do this test again in summer.

[@Eniz87]

Good video alot of details for EV drivers. I wonder when 60kw nissan will come... Thanks bjørn

[@robertbindler2481]

Excellent thank you
