Most Tahoe models come with large, supportive front bucket seats, and in both the first and second rows there's plenty of headroom and legroom. Adding middle passengers in the front two rows isn't the best idea, despite the Tahoe's size and the availability of bench seat in front and in the second row. There's a third-row seat available as well, but it's one of the more difficult of its kind. It's tough to clamber into, since the second-row seats only move forward a little, and legroom in the third row of the Hybrid is slashed by the battery pack, which is mounted under the second-row seats.
For cargo space, the two-row Tahoe is a champion, with 60.3 cubic feet available. Flip up a third-row seat in either version, and the cargo space shrinks to 16.9 cubic feet. There's storage and stowage aplenty, though; all Tahoes have cup holders for all, plus a huge glove box, a wide center console, and lots of door-panel storage.
Interior materials and trims don't quite have the high-end feel and gloss of those used in GM's Cadillac products, but they're among the best, and the Tahoe's interior is well isolated from road and wind noise.
