There's plenty of head and leg room up front, but rear passenger space is woeful for the class. Indeed, it's hard to think of anything from the family SUV class that has less room, or that makes it as difficult to get in or out of through such narrow door openings and tight footwells.
A BMW X1 and Volvo XC40 both provide much more rear room, and even other stylised designs, such as the Range Rover Evoque, serves its rear-seat passengers immeasurably better. And that's just with two adults in the rear; try fitting three adults in the back and it'll be a real struggle for the middle passenger especially, with a compromised middle rear seat that sits higher than the outer two, reducing its head room. Also, there's precious little room for anyone's feet between the underside of the front seats and the floor.
The boot is a usefully square shape, has no awkward load lip at its entrance, and some reasonable under-floor storage, too. However, all that's completely undermined by the fact that the main compartment is the size of a child's ballet shoe. Okay, there may be an element of exaggeration involved in that statement, but when you think we've fitted four carry-on suitcases in an Audi TT Roadster, five in a BMW Z4, and they're both two-seater sports convertibles, how many do you reckon we fitted in the UX's boot? Three. Yes, you did read that correctly, three. An XC40 can accept up to seven, if you’d like to know what you can expect from a family SUV with a good-sized trunk.
Passenger storage is reasonable, but not superb. There's a smallish glovebox and front door bins, along with a decent cubby under the central armrest and a couple of cup holders. Rear-seat passengers are served with a couple of map pockets but no door bins.
