Many years ago the Chevy Silverado had a reputation for a utilitarian, work-truck look and feel; but it broke markedly from that with its last complete redesign in 2007. Ever since then it's offered all sorts of luxury features—and for most of the model line, an interior that offers the comfort of a full-size SUV. On base versions, you can still get the work-truck layout, and space for up to six, however. Those luxury versions also compelled GM to lift the Silverado's game across the board, by improving its interior quality and fit and finish.
The cabin of any of the Silverado models is very spacious. In some directions, the Ram 1500 or Tundra may have a few inches more to spare, but there's excellent headroom and legroom all around. The one thing we miss in the front seats—whether they're the base bench or any of the buckets—is lateral support; you won't feel at all held in place in corners.
Opt for the bucket seats in front, and there's a very large storage area with a bin big enough for a netbook or tablet, a couple of Big Gulps, and some rubber-lined trays sized to hold smartphones and the like. The Silverado's big gauges fit the rest of the look, and big controls can be operated when wearing gloves.
If you need back seat space, go with the four-door Crew Cab. Crew Cabs are fitted with a rear bench and are good for three-across adult seating; the stadium-style rear seat has a 60/40-split design and can be folded up for more cargo space. But even here, the rear seatback is too close to vertical for long-distance comfort. The Regular Cab version has just a sliver of space behind the seat, and Extended Cabs are marginally better, with space to hold toolboxes and gear, but not much more. The back seat in Hybrid models is mostly like that of the other Crew Cab models, but with under-seat space compromised (room for batteries).
We've found all the Silverado models to be surprisingly hushed inside, with plenty of sound deadening and tight build quality—with less wind noise than you might think from such a tall, boxy vehicle.
For some truck shoppers, comfort is also related to how much extra cargo-bed space you have for stuff. And across the Silverado 1500 and Silverado Hybrid lineup measure 5'8" long on Crew Cabs and Hybrids; all other versions have beds that are either 6'6" or 8'.
