This morning Hyundai of Germany did a FB live walk around video of the Ioniq 5. Part of that live feed showed some basic dimensions of the trunk area as well as video of the Frunk. Here are some time stamps of the below video that does over the frunk and trunk area (twice). More info on Frunk starts at 44:10 Trunk Size info starts at 45:21: To edge of rear seat folded down (seat all the way back): 164cm (64-9/16") To back of front passenger seat (looks to be all the way forward): 196cm (77-3/16") And again at 47:35 To back of rear seats (all the way back): 97cm (38-3/16") Between Wheelwells: 105cm (41-5/16") Note: They showed the front passenger seat (headrest removed) and rear (40 split) folded down starting at 42:38.
Here is a screen capture of the false floor of the cargo area removed. I guess the hump in the middle is part of the Bose sound system (subwoofer?). Looks like there will be a cargo cover too.
Looks like he was asked to remove the livestream video. At least I was able to get a few dimensions from it.
They got a lot of very bad comments on the video, because it was very unprofessional, especially for an official channel. Probably would have been better if they had invited a regular youtuber. Some of them have done very good interviews for the ID.3 and other cars in the past. Was a much better format and better quality.
