Heat on 26 when i had an ICE car…lol. but not the heated seat as well. I think its pretty much normal.
As others have suggested, the Ioniq 5 has the big boot at 570 litres.
Quite a few vids on people using the ioniq 5 for camping and overnight its used 4 to 5 percent battery in Utility mode.
But you take the vids with a pinch of salt. The ioniq 5 Ultimate has memory seats etc.
