    It's hard to gauge the size in the photos but it's about the same length as the Prius Prime (182" for Ioniq 5. 182.9" for Prius Prime). It has a ridiculously long wheelbase at 118"/3,000mm. (Longer than the Hyundai's full size Palisade SUV)

    Quick specs:

    • Two battery sizes 58kWh and 72/77kWh (77 for US, 72 for other world markets)
    • RWD and AWD
    • 0-60 in 5.2sec to 8.5 sec
    • Up to 300 miles/480km on WLTP cycle
    • DCFC up to 350kW (10-80% in 18 minutes)
    • 18 cu ft of cargo space
    • 2.0 cu ft. frunk (RWD) or 0.8 cu. ft. frunk (AWD)
    • 3,500lb towing rating
    • Sliding front centre console (armrest can act as table for rear passenger and provide access between front seats similar to Gen 2 Prius when the console is slid rearward)
    • Legrests for front seats for passenger comfort while charging
    • Two 12" MFDs
    • Augmented (AR) HUD
    • Two power outlets (rear console and next to charging outlet) up to 3.6kW

    'the option of leaving out the other side' now there's a bonus :cool:

    any shots of the hatch?

    The first EV with a HUD and 350kW charging? And built by a company with a reputation for decent build quality.

    Hyundai Nexo (Hydrogen) is a good comparison to this sibling.

    I wonder how that magnetic dash would interfere with pacemakers and other electronic devices?

    Magnetic fields don't do anything to electronics unless they are *moving* relative to each other. Plus, the field from that dash is probably less than 1/4 inch deep.

    No issue.

    I'd the key features this has above the tesla model Y are V2L and in the US still qualifying for the tax credit. I really could have used V2L during snopacalypse (I lost electricity for 87 hours, I could have driven it to charge and to friends that were without power for 130 hours). I would have been able to run the fans to use the gas heat.

    Watch This: Hyundai Ioniq 5 Has These Features Teslas Don't
    We need to wait for real reviews, but on paper good job Hyundai. This gives people another good plug-in choices in a very popular segment. tesla model Y, Rav4 prime, and Ford Mach E.

    And a dash. And a HUD. And probably decent build quality.

    "Like the aforementioned BEVs from GMC and Porsche, the Ioniq 5 uses an 800V electrical architecture, that among other things means it's capable of extremely rapid charging—from 10 to 80 percent state of charge in just 18 minutes when connected to a 350kW DC fast charger. Four hundred-volt DC chargers are more common, but some clever tech on the Ioniq 5 means it can use these, too—the motor and inverter handle doubling the voltage to satisfy the battery pack."

    Can anyone parse this? This seems to me to say the battery is 400V but the power electronics double it for the motor, which makes it a 400V battery. Or is this an actual 800V battery like on the Porsche?

    Most EVs use a 96-cell series Lithium-Ion pack (the Prius Prime is unusual in being a 95-cell series pack, but close enough). Some call this a "400V pack", even though the battery voltage will range from about 350 to about 395 volts.

    EDIT: Found this on another link:

    "The Ioniq 5 can support both 400V and 800V fast-charging, and its multi-charging system will effectively step up the voltage with 400V hardware to achieve fast, stable charging."

    That seems to indicate it's an 800V battery with a boost converter for 400V DC chargers.

    Anyone have actual insight into this?

    I really like my model 3 dash better than the ioniq, but it is good to have choices. These are a matter of taste. Most of my passengers really liked the minimalist dash once they saw it, but it is not for everyone. HUD seems like a good option, but I wouldn't really use it much. The build quality of my model 3 is better than my gen 3 prius was but not in the same league as my previous lexus gs. I had initial quality problems, as it was built in 2018 near the beginning of dual motor. They needed to adjust my drivers door and the trim on drivers side. Car and driver had the same driver side trim issue on one they got in 2019. The first they gave me a loaner, the second they drove to my car to replace. It really is nice having tesla come to you to fix problems, but its better if they come out perfect from the factory. Initially the software left a lot to be desired. The on-air updates have been great. They even have made the car faster and more efficient (or maybe just allow me to use more battery). The problems with the X don't seem to affect the newer cars (Y and 3). Hopefully Hyundai will be better build quality but it will be the first model year so I doubt it right away.

    The Y is more efficient, longer range, and more powerful, but they are not selling the 240 rwd mile range model online (only if you go to a show room or call). I don't really like the styling of the model Y or ioniq 5 but again that is a matter of taste.

    Full specs are not out, but yes I would assume it is a 800 V battery with a DC-DC converter to use 400 V dc chargers. It is possible that they have 2 - 400V batteries that can be configured in series or parallel for charging. The V2L is 3.6 KW.

    Hyundai IONIQ 5 Project 45 price and specifications - EV Database
    max power is 232 kw on a 800V system. A 175 kw 400V ccs charger only adds 5 minutes (23 minutes 10%-80% versus 18 minutes on a 350 kw charger). A tesla model Y can use a full 250 kw out of a v3 charger but slows down above 40%, resulting in a slower charge.

    I have a friend with a Model 3 dual-motor long range and I went for a ride in it. The top three things I didn't like were:

    1. Sport-tuned suspension. I drive on a lot of bumpy roads and the suspension was nothing short of jarring on bumps.
    2. The tablet. Ugly, in a bad place, lousy way to see your speed, lousy way to interface to the car. I liked literally nothing about it.
    3. The way the doors require the windows to roll down to open. Absolutely insane design choice.
    As for the HUD, I'm now used to it on my Prime and it is to me a game-changer. There's a reason it's on so many airplanes - it's an absolutely HUGE improvement in situational awareness to not have to look down every few seconds. And, you know, most of these airplanes have true autopilots so that's not a reason not to have a HUD. I'd prefer never to be without one again. It's that helpful.

    Interesting site. I didn't know about it.

    Ioniq 5 10-80 on 175kW CCS - 23 minutes
    Ioniq 5 10-80 on 350kW CCS - 18 minutes
    Model 3 LR 10-80 on V3 supercharger - 34 minutes

    So, this thing charges at nearly twice the rate of a Model 3 on a V3 supercharger. Impressive.

    Tesla V3 Supercharger Test: We Find Out Exactly How Fast It Really Is
    5%-80% in a model Y or model 3 long range is now about 28 minutes. That is 10 minutes longer than hyundai on the 800V ccs chargers.

    326 miles x 70% = 244 miles in 28 minutes (really that first 5% is very fast so lets discount it since you likely will charge at 10% not 5%. That last 20% from 80% to 100% is really slow 33 minutes.

    Tesla modified the software to precondition the battery when it gets close to a supercharger to charge faster.

    Let's guestimate the long range ioniq 5 range is 275 miles, we will get the epa later in the year.

    275 miles x 70% = 193 miles in 18 minutes on the rare but hopefully more plentiful soon superchargers. The tesla model Y would take about 20 minutes. Yes it is faster but not much. The big thing on the tesla is the slow down as it gets more full. Hyundai likely has a faster charging battery technology, or is not providing the margin for safety. The lower priced MIC lithium iron phosphate in Chinese and European tesla model 3 standard range plus take twice as long to charge, and only peak at 75 kw. My guess is competition will push companies to be able to charge at the higher power levels longer.

    I would probably charge at no less than 30%, so the higher-end SOC charge rates matter more to me. Tesla's are really a lot slower up there.

    With the hyundai you may need to do that as ccs charger network is not built out well in north America. If you have a 326 mile range vehicle on a long trip with lots of chargers (tesla's network is now quite good but still needs work) why charge with 98 miles left of range. You probably still are a better candidate for a phev.

    Because the road might get closed ahead of me due to accidents or weather, because a forest fire might require a diversion, because a charger might be out or unavailable requiring me to backtrack to the previous one.

    Every one of those has happened to me.

    I have one. But it's a stepping stone.

    Any idea on how the cargo space is derived. 18cu. ft. is close to a 531L figure I saw from an UK source. Europe mostly uses a method for cargo space like the US uses for trunks; fill it up with standardized sized boxes, and count those. Where as the US directly measures the cargo space of SUVs, hatchbacks, and wagons. The box method underestimates the actual volume.
    The top selling hydrogen FCEV in the world, sure. The Nexo costs more, and doesn't have an AWD option. Actual price difference is unknown, but around $10k is likely. The Nexo has a 115 volt inverter in the back seat, which isn't as versatile as the Ioniq 5's V2L feature.

    We don't have actual specs yet, but the longer wheel base means the Ioniq 5 has up to 9 inches of extra leg space. That does mean less cargo space. The Nexo does a better job of packaging the fuel tanks than the Mirai for less space loss, but AWD is not possible as they are

    The Nexo has longer range, but having to regularly visit a station vs refueling at home is a personal preference.

    It's just a piece of steel. You use fridge magnets to stick things to it. @Mendel Leisk it is probably the most retro thing on the car.
    The Ioniq 5 range will likely be lower; 267 miles. Outside of fast charging, not a really big difference.

    The issue facing the fast CCS now is availability. It'll grow faster than hydrogen, but how many are out there now, and by the time the Ioniq 5 arrives? Good chance the CCS most users will encounter now is just 50kW.

    Essentially, you all are saying this thing's efficiency will be around 20% worse than a Model Y - 60 miles less range with the same sized battery. I have a hard time believing that will end up being the case.
