Like its main rivals, the Audi Q5 and Volvo XC60, the X3's rear seats are best suited to two adults or three children. Whoever sits in the middle has to deal with a narrow seat base and splay their feet either side of a chunky transmission tunnel running along the floor.
A Discovery Sport has slightly more leg room in the back, but the X3 is slightly roomier in the back than an XC60 or a Q5. Two child seats will fit with ease either side of the middle seat, and access to the rear is good, too.
Both rear passengers get a cubbyhole, but you’ll struggle to fit a large water bottle inside. There are pockets on the front seatbacks for extra storage, though, and rear window sunblinds are available as options, as are heated rear seats.
There's no seven-seat option like there is on the similarly priced Land Rover Discovery Sport.
