Ioniq 5 vs. MYP... The Performance will win of course. Ioniq 5 vs MYLR is what I'm comparing and in reality the Ioniq 5 AWD might actually edge the MYLR.
I own both, and use I5 as daily driver last 3 weeks with several long trips. Acceleration on Ioniq 5 AWD is actually pretty ok. Pretty snappy and quick off line, but, it feels very different vs MY after you hit 60. It's like in a sprint that I5 just used a lot of energy to get to that sub 5 second number and is gasping for air once it hit the goal, where as Tesla would feel like it did that acceleration with relative ease and still has lot in the tank, so to speak, to go on much longer. It's a bit difficult to describe, so you really need to test drive them both to feel the difference. No right or wrong answer, it's just a different car.
Ioniq 5 is actually a very good car from Hyundai, and I would recommend it if you mainly care about comfortable and soft suspension ride. It's a really good transition car from someone who's very used to traditional ICE car and don't want to jump straight to the minimalist design of Tesla. Yes it has HUD, which I think it's cool at first but really don't care much for it after a few days. The problem is that HUD doesn't integrate with Apple CarPlay so if you use map on the phone, instead of built-in Nav, HUD is basically useless. And the build-in Nav is a disaster is the only word I would use to describe. It is not, and worth repeating, NOT location aware when you type in partial POI in search. For example, if I type in a partial coffee shop name, it will list suggestions with random coffee shops around the US. Only after you click enter to go on next step it will then show more relevant information. it is very annoying, and takes at least 2 additional presses to get navigation started. This is a stark contrast to how fast Tesla can start navi. Also the highway driving assist is just OK, it works but it's definitely not as good AP. HDA sometimes drives like a drunk driver that is having a hard time staying steady in the center of the lane, and shifting left and right too much. It's also not great at dealing with bigger curve, occasionally would steer itself over the line to either side. It's not terrible in most cases, but just need to be a little careful when you are surrounded by cars.
Also the key fob on I5 is super annoying, having to turn on and off the car, and lock the door are something that all Tesla owners would hate.
But if you can overlook some of minor annoyances, Ioniq 5 is actually not a bad car. if you can get it at MSRP and take an advantage of $7500 rebate it's a very good alternative.
