There’s plenty of room in the front seats – as much as you’ll find in any traditional family hatchback, or in a Toyota Prius, for that matter – so two tall adults will have no complaints about head or leg room. The rear seats also have enough leg room for tall passengers, but anyone above average height might brush their head on that sloped-back roof. This is one area where the Ioniq loses out to regular hatchbacks, such as the Volkswagen Golf and Skoda Octavia.
On paper, the Ioniq's boot looks considerably bigger than that of a Prius, but it's quite shallow and has a high load lip. It’ll still hold a buggy, though, and the rear seats split 60/40 and fold down to help with longer loads, but leave a hefty step in the extended load bay when you do fold them down. The Plug-In Hybrid will still take five carry-on suitcases with the rear seats in place, though. Buyers of the EV model should bear in mind that its bigger, rear-mounted batteries further reduce boot space.
