GMC Sierra 1500

Even though the 2027 Sierra 1500 has all-new sheet metal, it’s so similar to the 2026 body that you might need to look for the trapezoidal grille and more complicated headlamps to identify one.

Trim-specific details distinguish various versions of the Sierra, as seen in the lower front design, wheels, and exhaust outlets. GMC says there are available welcome and farewell light animations, addressing a need you probably didn’t know existed. Trucks … with animations.

GMC hasn’t announced the body configurations, but it’s reasonable to expect the Sierra 1500 will once again be available as a regular cab/long bed, extended cab/standard bed, crew cab/standard bed, and crew cab/long bed.

The most extroverted trim is the Sierra 1500 AT4X. It enhances the truck’s off-road capability with 35-inch Goodyear Mud Terrain (MT) tires, a 2-inch suspension lift, off-road shocks, front and rear electronically locked differentials to optimize traction, and a distinctive front fascia. Like the previous model, the AT4X will again be sold with the AEV Edition package, which further fortifies the truck.

The redesigned cabin is simpler than the outgoing model, with screens spread across the dashboard. All combined, GMC says there’s more than 60 inches of total screen. The digital real estate includes a 12.2-inch instrument display, 16.3-inch infotainment screen, and 11.5-inch front passenger screen. Plus, there’s an available 15-inch color head-up display and an 8.5-inch rearview mirror display, which can show behind the vehicle when the view is being obstructed by passengers and head restraints.

Different trims come with specific materials, including leather and real wood, along with stitching and accents. The AT4X has a flat-bottom steering wheel, increased seat bolsters, perforated upholstery, stainless steel speaker grilles, and abundant stitching.

Adding to the luxury experience is an available panoramic roof (standard on AT4X) and a new MultiPro center console that slides and folds, allowing for different configurations between the driver and front passenger, including transforming into a flat table well-suited to placing a laptop or having a picnic.

The 2027 GMC Sierra 1500’s powertrains only look like carryovers from last year. GMC says the turbocharged four-cylinder has been upgraded. For reference, the outgoing version of that 2.7-liter engine produces 310 hp.

The 3.0-liter turbodiesel six-cylinder engine may be changed only slightly. The previous truck produced 310 hp, and it achieved 23 mpg overall in our tests.

The 5.7-liter and 6.6-liter V8s are next-generation small blocks. GMC says these engines deliver improved performance and durability. The last V8s cranked out 355 hp and 420 hp, respectively.

This time around, all four engines will be matched with a 10-speed automatic transmission. There has been no mention of a hybrid to rival Ford and Toyota’s truck offerings.

GMC has provided little information on the active safety features in the 2027 Sierra 1500. The 2026 model comes standard with forward collision warning, automatic emergency braking with pedestrian detection, and lane departure warning, while blind spot warning and rear cross traffic warning are optional. We hope that these last two features are made standard with the redesign.

GM’s Super Cruise active driving assistance system will be available and feature hands-free driving while towing. The system will come with a free three-year OnStar trial to support Super Cruise functionality.
