Prime vs. Hyundai Ioniq

LKAS is coming on the 2018 Ioniq so that is one thing it has been missing on the US models which has been std in every other market

the lack of rear wiper seems to be a common niggle for drivers of both cars, but to be honest I have not found it necessary on my car, so long you apply one of the many rain repellent coating the water runs off at fairly low spped, the other issue is the lower half of the rear wwindow on the Ioniq does suffer badly with spray / dirt, does the prius suffer similar ?

as to android auto / apple carplay the reception is mixed over on the other (dark)side, some love it, some hate the fact you need to plug the phone in via a cable, some complain the available apps are to few and very limited, so it would seem it needs a couple more revisions before it is worth having

at the end of the day no one car will make everyone happy, no one size fits all, if it did life would be very boring, so the more choice the more people will be happy and people will need to make fewer compromises on their cars to get what they personally want from them

 

Here's what the battery looks like in the Prime. A large rectangular box.



Hard to tell from the picture but I can easily reach under the battery, must be at least 3+ inches of space between the floor and the bottom of the battery. It would certainly be possible to design a battery that traded some of the space under/around it for a less crippled cargo space.

 

that's similar to the battery in the Ioniq plugin

 

Looks like there’s a lot less reinforcement and spacing with the Hyundai battery. I wonder if longevity will be an issue, but there is a huge exhaust pipe.

 

simply a better packaging job by hyundai, or is there more to the tale?

 

Longevity and accident-resistance need to be taken into consideration.

 

absolutely, they'll probably get creamed by the insurance institute crash testing. we won't know longevity for many years, but i think they have a lifetime warranty.

 

Was not aware the Ioniq produces a little more torque than the Prius'. Not having a portion of the ICE's torque output always going to a generator could be an efficiency advantage.

The HSG can also provide regen braking, it just isn't very good at it. It is a small 10kW motor, and is on the front end of the engine. Brake energy is spent spinning the ICE before it gets to the HSG. It is more apparent in Sport mode because I suspect the mode keeps the ICE clutched in more often.

I think the reverse gear advantage is an edge case. I never had worries about backing up my 2005 Prius. Now, if both had a meaningful tow rating...

We'll see how much price reduction Hyundai accomplished once they start discounting.

The Ioniq battery has about twice the capacity of the Prius one; 1.56kWh to 0.75kWh. That's Li-ion, the NiMH Prius pack is 1.2kWh, but has the same usable capacity as the Li-ion one.

Both cars use air to cool the battery. That space underneath might be necessary for that. The Ioniq pack also appears to be sitting on shock absorbing mounts.

The Ioniq PHV pack slips under the rear seat, so there is less of it in the cargo area.

Hope that gives an idea.

 

"I think the reverse gear advantage is an edge case. I never had worries about backing up my 2005 Prius." From Mr. Troll.
I stopped driving in reverse years ago; especially on the freeway. The cops just kept getting real upset with me!! Mr. Troll, I'm with you, who cares about all the motors, engines providing rearward power; to climb Pikes Peak in reverse?? My old 2012 PIP, and even my 3 cylinder Honda Insight hybrid coupe had adequate horses for climbing backwards up hills. Let's focus on necksnapping forward motion, now you're talkin' !

yep, in the US the Ioniq has a lifetime battery warranty for the original owner only, here in the UK and a number of other countries it is 8 years or 125,000 miles / 200,000km

the warranty seems to class 70% of original capacity to be the relevant figure for being classed as a failure from the information we have seen

 

I notice there seems to be far less gap between the boot / trunk edge in the prime than the Ioniq plugin, how much of a rear impact would be required to cause damage to the primes battery pack/ cells?

we need to see full rear end crash test data to get a good comparison between the two

 

the reverse gear issue was actually brought up on here by a prius driver a few months ago if I remember correct,

as I have never driven a prius, like many on here have never driven an ioniq it is difficult to do direct comparisons, I know how the Ioniq works and drives, you guys know how the prius / prime works and drives so between us we should be able to compare the two cars in a fairly accurate way

 

Ah, you wonderful optimist you!! My car's better than yours, and that's that!!
Car opinions are SO damn subjective, the only things you could fairly compare would be number of tires, or brand of stereo, number of speakers, etc. But that is also so bloody boring. There's no getting around the fact that you must drive/use/live with both cars to compare them, and the best you'll get from that is a SUBJECTIVE opinion of the experience. Opinions are like a..oles, everybody's got one!! As long as you're happy with your puppy, that's all that matters!

I first came over here to find detailed info about the prius and any general info about hybrids and how the eCVT worked, as well as provide some information about the Ioniq as there was a bit of hear say and incorrect info,

if you look at my posts I try not to get into mine is better than yours type posts, as I know I am I am in the lions den, I restrict my posts to the specific ioniq related threads

I provide specific info when needed usually about hard topics like how the drive train works etc. that's all

cars and how they drive is as you say very subjective, as is the styling and the layout of the cabin and controls

happy with mine like you are happy with yours, 20,000 miles since November no issues, normally seeing 72+mpg(UK) / about 60+mpg(US)

 

We're definitely on the same page; my best to you and your vehicle!

interesting that they've defined a failure %, i wonder if there will be a specific way of testing? for toyota, it's nothing but the triangle of death, and that usually due to bad cell(s) not capacity decline.

 

The battery warranty seems much more useful in the Ioniq than the Prius if they truly measure it by percentage of original capacity.

 

that is what we have been told, 70% but no way of the owner measuring it, we do have a couple of member who are working on using torque app via an OBD connection, so I assume they upload data when the dealer connects diag terminal during service

they say they can "replace or repair" the battery at their discretion so question is will you get a battery with a 100% capacity or one with 75-80%

we wait to see when we have a failure, but if what you guys over have seen, batteries last a fair time so I think it will be several years

also the traction battery warranty varies country to country, here in the UK it is 8 years / 125,000 miles end of, in the US it is unlimited mileage for the first owner only, it is not clear / known what the situation is for later US owners, I think it will fall back to the 125,000 / 8 years of other markets but we don't have firm information on that, as battery warranty for later owners will be relevant to 2nd hand prices

 

It will be 8yr/100k miles for the PHEV here; that is the mandatory federal emission warranty. It might be 10yr/150k miles in CARB states.

 

I test drove the Ioniq yesterday and I was not impressed. We also test drove a Prime yesterday. I didn't love it either, but it was better than the Ioniq. We will be getting another Prius. The one thing I liked were the dual 12v chargers since I have too many things I plug in. That, and supposedly the higher trims have heated and cooled seats. I love having cooled seats in my other car. The dealer only had the base model in the Ioniq- ugliest pattern on the fabric seats I have seen in a car and the whole thing felt cheap.
