VERSATILE SIERRA OFFERS LOTS OF CHOICES FOR THOSE LOOKING FOR FULL-SIZE PICKUP
Introduced as a 1988 model, the Sierra pickup is the longest running vehicle in the GMC fleet, edging GMS’s Yukon SUV that debuted four years later for the honor.
But with large gaps between major redesigns, the 2026 GMC Sierra 1500 is in only its fourth generation that came about in 2019. Though it shares very much of its DNA with the Chevrolet Silverado, the GMC Sierra is considered a step up in class when it comes to refinement and premium features over its Chevy “sibling.”
The 2026 GMC Sierra 1500 is offered in eight trims with three cab figurations, three bed lengths (depending on the cab), and four engines determined by trim selected. There’s even a turbocharged diesel available along with turbocharged 4-cylinder gas engine and two different V8s, one listed at 5.3-liter, the other at 6.2-liter.
The base model is the Pro trim and is followed up the ladder by SLE, Elevation, SLT, AT4, AT4X, Denali, and Ultimate Denali.
This review is based on the 2026 GMC Sierra AT4X which was introduced as a 2022 model and adds premium features to the AT4 trim that was part of the redesign of 2019.
Both the AT4X and AT4 are tuned more for off-road ventures than the other trims with the AT4X getting more in the way of upgraded premium features as well.
Among standard interior features on the 2026 GMC Sierra AT4X are full-grain leather seats, heated front and rear outboard seats and ventilated front seats, a leather-wrapped steering wheel, power steering column, dual zone climate control, and a power sunroof.
Numerous tech systems operated mostly on a 13.4-inch touchscreen with built-in Google compatibility. They include wireless Android Auto and Apple CarPlay, a 12-speaker Bose premium sound system, wireless charging, and navigation.
There is also a 12.3-inch digital driver information center, a 16-inch diagonal head-up display, a rear camera mirror, and adaptive cruise control. Keyless open with push-button start is standard.
A suite of features in GMC’s Pro Safety systems includes forward collision alert, automatic emergency braking, lane-keep assist with lane-departure warning, following distance indicator, and automatic high beam toggles.
Front and rear parking assist, trailer side blind zone alert, rear cross-traffic braking, front and rear pedestrian alert and HD Surround monitoring also are standard.
The 2026 GMC Sierra AT4X also comes with a steel front bumper, LED cargo area lighting, spray-on bed liner, LED daytime running lights, and GMC’s multipurpose tailgate.
The base Pro trim 2026 GMC Sierra starts at under $47,000 but the AT4X resides at the higher end of the pricing chart. Starting MSRP is listed at $79,400, which is a pretty steep increase.
My test 2026 GMC Sierra AT4X included the AEV (American Expedition Vehicles) package that added an AEV front chassis skid plate, AEV transfer case skid plate, AEV stamped rear bumper, 18-inch high gloss black aluminum wheels, AEV rear differential skid plate, rocker protection, AEV branded floor liners, AEV fuel tank skid plate, and more.
The optional 6.2-liter naturally aspirated Ecotek V8 engine added another $1,500. It is rated at 420 horsepower and 460 pound-feet of torque and is mated to a 10-speed automatic transmission.
Premium fuel is recommended for best performance. Government figures show efficiency ratings of 14 miles-per-galloon city, 16 highway, and 15 combined, which coincidentally are the same number for models using the 5.3L V8 that runs on regular octane gas.
With all the options the final price for my test 2026 GMC Sierra AT4X came to $89,945 including a hefty destination charge of $2,595.
What I liked about the 2026 GMC Sierra 1500 AT4X: The cabin is spacious (43.4 inches of rear legroom) and loaded with lots of fairly easy to use tech features. The digital mirror and surround vision camera are nice safety features.
What I didn’t like about the 2026 GMC 1500 AT4X: The setup for off-roading ventures eliminates a much-needed running board for cabin access. (Though you can use the optional protective rocker panel rails if you are careful.) It’s not easy to find parking spaces in mall lots to accommodate its size. Options like the AT4X AEV package quickly run up the price.
Would I buy the GMC 1500 AT4X? Not in the market for truck of any size but especially not one this big. Your decision will be whether to pay extra for the interior upgrades like full-grain leather heated and cooled seats or make do with the less expensive Chevy Silverado.
