Used 2015 ChevroletSuburban 1500 LT 5.3

The newly redesigned 2014 Chevrolet Silverado pickup truck is in dealerships, which means that GM can now turn its attention to introducing the related full-size sport-utility vehicles that are based on that truck, the new 2015 Chevrolet Tahoe and Suburban.

The last major refresh for the trucks occurred in 2007. This is now the 12th generation for the Suburban (fifth for the Tahoe), making the Suburban the longest-running nameplate in the auto industry at nearly 80 continuous years.

For 2015, both the Tahoe and Suburban get a thorough reworking inside and out. What applies to one also generally applies to the other — the only big difference between the two models is length, with the longer Suburban featuring more interior passenger and cargo space.

Outside, styling updates are subtle but significant. The headlights and front ends are obviously different, but most interestingly they are altered from the Silverado as well; no longer do the full-size SUVs and full-size pickups share sheet metal.

Doors and side glass are redesigned to fit into the bodyside instead of wrapping up into the roof. The glass is smoother overall down the sides than before, culminating in a more squared-off look for the rear that also improves interior space.

Power comes from GM's revised Ecotec3 5.3-liter V-8 engine, which makes 355 horsepower and 383 pounds-feet of torque. The engine features cylinder deactivation for improved fuel economy. In terms of towing capacity, two-wheel-drive Tahoes are rated at 8,500 pounds and four-wheel-drive models at 8,300 pounds. Two-wheel-drive Suburbans are rated at 8,300 pounds and four-wheel-drive versions at 8,000 pounds.

New on the inside is a completely revised console that is more carlike and made from significantly higher-quality materials. Like the exterior sheet metal, the dashboard is not shared with the pickups. A choice of multimedia systems is available, including an 8-inch touch-screen featuring Chevrolet's MyLink system that slides up to reveal a storage cubby behind the screen.

Interior passenger room is improved, with 2 inches more legroom for the second-row passengers and a new power fold-flat seat for the third row. No longer is the third row removable — like the Ford Expedition, it folds down into the floor at the touch of a switch in the cargo area. Another switch also drops the second row, so you can create a relatively flat load floor even when standing at the rear hatch. The downside is that a false floor now adorns that cargo area, resulting in a higher lift-over height and the loss of several inches of cargo height. That false floor is covered and made into storage however.

The Tahoe/Suburban can be had with some new high-tech equipment for 2015 as well, including forward collision alert, blind spot detection, lane departure warning, a safety alert seat, front and rear park assist, center side airbags for the front seats and even a Blu-ray player for the rear seat with a 9-inch screen. The SUVs can be optioned to have five auxiliary power sockets, a 110-volt power outlet and six USB slots for personal electronics. GM is also offering the latest version of its Magnetic Ride Control adjustable suspension as well.
