The 2014 Hyundai Tucson is about middle of the road in its segment for interior space. There's a bit more usable room than in the Nissan Rogue or Ford Escape, although definitely not as much as in the Honda CR-V, Toyota RAV4, or Subaru Forester. Yet its long wheelbase gives it a nice ride and, perhaps, the impression of a larger vehicle--especially if you're in the front seats.
There's a good amount of head and leg room in front. But the seats themselves have good back support, but the bottom cushion is short and tilts down a bit too much; and that can make them uncomfortable on anything more than a short drive. For 2014, Nissan has added a standard tilt/telescopic steering wheel, as well as steering-wheel audio controls on all, including the base GLS; and cupholder illumination is now included on all models.
Two adults will fit easily in the Tucson's back seats. We'd recommend the cloth ones over the leather upholstery, which seems to bring a less shapely, more flat seat design. Two-stage recline and 60/40-split seatbacks are now included, so that might aid comfort.
There's no space for a third row in the Tucson, but it does have impressive cargo space, considering its very compact exterior. Fold down the seats, and you get the sort of rectangular, wide-open space that's good for pets--or moving small pieces of furniture if you fold the second-row backrests forward.
Otherwise, within the cabin there are plenty of smaller storage spaces--with cubbies and bottle holders in the console and door panels, and a deep glove box. The only surprise is that there are so many hard plastics inside; but fit and finish has been good in all the Tucsons we've driven. Look for new interior colors this year to help keep the cabin fresh, too.
