I agree with those above essentially saying the Kona has awkward, but not "ugly" styling. The old Ioniq (not the new Ioniq5) & the Niro have always been OK, conservative styling. I think the recent Soul styling updates make it look kinda cool. All subjective of course.

As for the real topic of this thread, the Ioniq 5 (and it's cousin the Kia EV6) looks very cool. Most would agree with me on that. Pre-orders have already proven this to be true.

The Ariya will compete directly with all the new stuff coming out. It looks good too, so the market is getting competitive. Plenty of nice EVs coming out.
I like all of them, but styling is always very personal... mostly.

To me the Ariya is a bit bulbus, which isn't bad, but I can't help thinking its targeted more toward the traditional (aka older) folks while the kia and Hyundai are looking for the younger folks. YMMV.

Good video of the Ioniq 5

The price he mentions is 44k US.

I like the outside but need to see the interior in person

There has been a lot of discussion in the Ariya thread of the charging for Ionic 5. Here is some of the first real world data.

Some of this data is for the European version, which has a smaller battery - ~72 kWh?

Well, to prove a point to the media. Is there enough hacking know-how of the Leaf to make a large part of it's battery unusable and then pull up to a 50 kW QC and get the same 10->80 charge times? :lol:

It could help drive home the point to others. A lot us here understand what is going on with the hand-waving when it comes to these charge times, but sometimes it's easier to show people in practice than in theory. :geek:

Easy peasy. Call 5 kWh in the battery "15%" and call 15 kWh in the battery "80%"
IIRC the 30 kWh LEAF has a 150 Amp system. No problem getting a flat 1.9C charging curve.

Woohoo!! Nissan engineering at its finest, even 5 years ago a cut above the best that Tesla, Porsche, and even Hyundai have ever offered !!!!

A little CAN-BUS hacking could probably do it and make it easy to film a charger doing some insane 10%->80% charge in 5 minutes :mrgreen:

Anyway, I know off-topic, I'll stop hijacking this topic.

If it’s true that Hyundai is achieving a higher fast charging speed by adding a much bigger buffer to the battery, why not instead lower the fast charging speed to a safer level and then make that buffer capacity into useable capacity? I have to think most people would prefer say 350 miles of range and 150 kW fast charging speed over 300 miles of range and 225 kW fast charging - faster charging is nice, but not having to stop and charge at all is nicer.

There is no trade-off here, it is just marketing deception. A bigger buffer does not change the charge curve (kWh added over time). The big buffer is way more idiotic than you imagine.

I'm curious, what evidence do you have for the total capacity of the Ionic 5, and thus the size of the buffer?

Personally, if a bigger buffer gives a reduced degradation rate and/or allows usable capacity to be opened up over time to maintain 'as new' range, I'd prefer that, subject to the price, weight and volume difference. Guaranteed range over the whole ownership period is more important to me than max. range when new which will degrade significantly over time.

As to whether range or charging time is more important, just depends on the person, and they can be traded off to some extent depending on the available infrastructure and use case. Neither are adequate yet for my needs, but charging time is probably closer.
