Kona Vs Ioniq efficiency test, Hyundai's Electric cars compared

Hyundai's Ioniq Electric is well known for its efficiency but how much more efficient is it than my Kona? Is it worth considering the new Ioniq to gain more miles per kWh, maximising my solar generation been further?
With a great coe. of just .23 Vs .29 for the Kona is should make a decent difference. The Ioniq weighs a fair bit less too.
I've hatched the idea of a "follow the leader" style test attempting to give an impression of the difference. This test isn't scientific especially with a minor cock up on the resets of the trip , but with equal roads and speeds, using SCC often to maintain a decent distance removing slipstream effects and of course equal temperatures and warm up times, I'm happy this result is within a few percent.
The result astounds me.
Just 0.1 - 0.2 mls/kWh difference and thus is with the bigger, heavier 64kwh Kona. The 39kwh is rated 0.3 mls/kWh more efficient!!!!
Upon driving home after test, I achieve my best even mls/kWh with a warm battery after a rapid charge. 7.4 mls/kWh over 9 miles. Apparently Justin has never seen a number that high on the Ioniq without cheating.
It's clear therefore the Ioniq and Kona are virtually equal in efficiency at slower speeds and the Ioniq only starts to outperform the Kona as speed increases.
Even now a few days later I shocked and proud of my Kona. What a car.

Did our first big trip. Gom started at 455 km, ended at 90 km. Overall, spent 4 hrs in the car. Eventually ran the battery down to less than 20% or to the red lines. Spent 1 hr fast charging back to 80%. (it is free in BC Canada). Charged the remainder 20% at home using 110 v. Was very pleased with the distance traveled without charging.

Good test, like you I don’t do motorways if possible, they’re boring and nicer to do a scenic drive when you can. Can’t wait to get my Kona next Wednesday from just evs. Like you I’m getting all my power from solar for our leaf 2zero at this time of year 99-100% with minuscule 1% from the grid or our storage battery, as I tend to leave it in charge when at home. No doubt when we get the Kona I’ll be swapping them over as they fill up. Thanks for all the great videos.

[@TCPUDPATM]

Granted there are some differences when you're testing two different cars this way, but I think your test is quite valid down to around the +/- 0.5 mi/kWh mark if I'm being skeptical. I'm quite surprised as well, but agree with your theory that the Ioniq would pull away in terms of efficiency if you talk purely about sustained high-speed driving. Thanks for the video, and thanks to Justin!

[@dennislyon5412]

The results were closer than I would have expected. If you guys are able to run a distance at 70 mph - that’s where that Ioniq will shine. Very good numbers for both cars on such a cool day. Interesting how the efficiency seems to pick up - a lot - as the temps increase. Assuming the roads/other drivers will let you - how about a test to see what speed/driving style it takes to keep the average mi/kWh above a certain minimum point, such as 6.0 mi/kWh - just to challenge you. :-). Good discussion, Nigel!

To access more parameters of these cars you can use Car Scanner ELM OBD2 app, it has profiles for several EV and PHEV cars, including Kona EV, Niro EV, Ioniq EV and PHEV, Toyota Prius, Chevrolet Bolt, Volt, etc. Very detailed data for BMS, electric drive, current, SOC, SOH, etc.

[@daves1646]

Wow! I'm quite pleased to see how close the Kona came to the Ioniq!! Stateside, the Ioniq is pretty much as effiecient as EV's come for the current lot of new ones. High end of 4.x miles/kWh is quite nice, especially if it was a cooler day. Kona sounds like an outstanding pick if with the large battery you can manage almost 5 mi/kWh on the highway. Thanks for the great comparison!! I don't think I would give up the range difference for 0.2-0.4 miles/kWh. A question: at 4.7-4.8 miles/kWh, isn't the Kona ahead of a Tesla Model 3 as well? That's excellent.

[@TheReubenBonnici]

The driving style makes a big difference. Same driver has to drive them to compare but then you won't have the same driving conditions. Very difficult to do a fair comparision.

[@vk6xre]

Weight has a bearing on energy used to accelerate, some of which is recouped through regen. There is a minor affect on rolling resistance. Once the vehicle is up to speed then the energy required is only that needed to overcome losses. Losses being Aerodynamic drag and rolling resistance. At low speeds Aerodynamic drag is small but increases non linearly as the velocity increases. The Kona has a slightly worse coefficient of drag and a slightly larger frontal area and therefore more drag, but not that much. At low speeds there wouldn't be much between them as one presumes the electronics and motor are of similar design and efficiency. Here is a question, which is more efficient. To accelerate to 60 mph like a bat out of hell or to creep up on it? In other words, a large amount of energy for a short time or a smaller amount of energy for a long time? Are we carrying on old ICE traditions into the new era?

Do you draft trucks on arterial roads and motorways using adaptive cruise control?.

[@PaulMansfield]

I'm wondering whether Hyundai have upgraded the electronics in new Ioniqs to match the Kona?

[@ruedigerpreiss9307]

Interesting but to be expected - or actually, I am quite surprised about the efficiency of the Kona electric! a) Ioniq definitely is a lighter car (1435 kg vs 1685 kg); 250kg difference is quite a lot! And b) it also seems more aerodynamic!

[@therandomtester9561]

It appears weight isn't as important as you'd think. At steady speed weight doesn't matter. Yes it uses more during acc, but on the flip side you have more potential energy thus more regen. In a drive with a lot of big variations in speed, yes it would matter some. I expected a lot more difference because of the aerodynamic

@@therandomtester9561 On motorways the Kona isn't doing that well ... the mpkW shrink quickly once driving over 60mph

[@therandomtester9561]

@@ruedigerpreiss9307 from about 50km/h the old Leaf seem to use 10-15% more for every 10km/h you increase the speed, tested up to about 90-100 km/h. That should be true for all other cars as well. Bjørn Nylands has tested many cars and at much higher speed, if you do the math you'll see roughly the same increse there as well, pretty steady increase for every 10km/h increase in speed. So nothing special about the Kona over 60mph..

You boys were hyper miling on the duals. I got 250 watts per mile in my Tesla 3 LR in 6 to 8 degrees today doing 65ish today. At 70 during 15 degrees its circa 230 wats per mile so 4.5 miles per KW. Looking at these tests as looking at changing my wife's ICE to EV. What battery is your Kona?

[@EVPuzzle]

That's no hyper miling . 64kwh in my Kona

@@EVPuzzle it is for me 😉

[@HyperTeHK]

You should have switched halfway who drives in front, the realworld difference will be a little bit larger. Stil amazing cars, would very much swap my Leaf for either. Ioniq wins more on higher speed, lower speed the difference will be minimal.

You provably wont want a less efficient car in the future I have an ionic and I dont want anything else but I'm waiting for 2020 plug in ionic

I do 108 miles a day what you think about it be too tight Keeling in mind if there's traffic how much is charging cost home and pump in pounds ? Or do you think ionic better for me hybrid

The more the miles the more you save. Go electric not hybrid. 216 a day is no problem at all for the Kona without charging. It's gave to be blizzard minus 10c to even get anxious

@@EVPuzzleSlim? It's pretty much the same width. the Ioniq has much better space. Also better than the Kona is the Niro, when comparing 1st gen.
