We came away impressed by the Sierra 1500 AT4X’s balance between being a serious utility truck, a luxury cruiser, and a robust off-roader. In the GM pickup truck big picture, it slots in neatly above the more hardcore Silverado as the premium choice that will get you where you want to go in supreme comfort. The drivetrain and suspension are top-notch, but where it’s clearly weaker than the Silverado ZR2 is in its approach and departure angles. Where it’s stronger and where a large chunk of your money is going to is into the ride and cabin quality, which GMC is close to executing flawlessly for its demographic; that demographic, of course, being people that can happily drop $75,700 plus a $1,695 delivery charge on a new pickup and want extra style and luxury to go with their off-road truck needs.
If that’s you and the ZR2 level of approach angle isn’t a dealbreaker, then we see no reason not to recommend the Sierra AT4X. There’s not much that’s going to stop it from getting where it needs to go, and it’s supremely comfortable. Not just comfortable for an off-roader, it’s comfortable compared to any truck on the market.
