The five-door Ioniq will seat five adults with relative ease, and you’ll be able to fit all of their luggage in the boot – as long as they pack lightly. That’s because while some older plug-in hybrid models had extra motors and battery packs shoehorned in wherever they'd fit, the Ioniq was designed from the ground up to accommodate this powertrain.

Hyundai Ioniq Plug-In interior space, storage & comfort

Passenger space in the back is decent enough, but the aerodynamic shape of Ioniq limits headroom slightly. Those over six feet tall may feel their heads brushing against the roof – the more boxy Nissan Leaf offers more space inside. At least their knees shouldn’t touch the backs of the front seats.

If there are only two rear passengers, they’ll be able to make use of the central armrest, which has a couple of cupholders. There are also rear air vents mounted between the front seats – this structure may cause an issue for a third (central) rear passenger’s feet. As you’d expect, the front occupants will be the most comfortable, with decent headroom. Those leather seats are comfortable and supportive, too.

Boot space

The regular Hybrid offers 443 litres of boot space but this Plug-In version loses more than 100 litres because of the extra batteries beneath the boot floor. There’s also a space-saver spare wheel, which gives peace of mind but takes up a fair bit of room. Still, that’s only slightly less than you’ll find in the Toyota Prius Plug-In.

But you’ll need to pack wisely if you’re carrying a full complement of passengers and luggage – don’t forget you’ll also need to find room for the charging cable, unless you leave that at home. At least the rear seats split 60:40 and fold. They don’t go completely flat, but yield a total boot space of 1,401 litres.
