There is plenty of space for passengers and storage. We traded in a Ford Fusion sedan and the Ioniq 5 has much more storage space than that did. One of the long road trips I mentioned was a camping trip. We were able to bring two big tote bins, a big cooler, a canopy tent for the picnic table, folding chairs, sleeping bags, air mattresses, extra blankets, and two dogs on the back seat. As a bonus, we got an adapter that plugs into the charging port and can power a hotplate for boiling water faster than a camp fire (also serves as back up power for my house if the power goes out, can run an extension cord down to the freezer). There is a small frunk, we mostly use that for emergency supplies.

I'm above average height and can fully extend my legs in both front seats and never have issues with head clearance. I like the space between the two front seats as well being mostly open concept as opposed to the closed spaces in Teslas. Feels spacious for every day driving and on road trips can fit a soft sided cooler as well as a food bag.
