2026 GMC SIERRA 1500 AT4 4WD 6.2L V8 CARBONPRO PREMIUM & TECH PACKAGES SUNROOF ACTIVE EXHAUST ONYX BLACK LANCASTER PA
This 2026 GMC Sierra 1500 AT4 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission. Finished in Onyx Black with a Jet Black and Kalahari leather interior, this is a loaded AT4 featuring the CarbonPro Edition, AT4 Premium Package, Technology Package, power sunroof, active exhaust, and 20-inch wheels.
The 6.2L V8 delivers 420 horsepower and 460 lb-ft of torque, giving this Sierra serious acceleration, impressive towing performance, and the unmistakable sound of a traditional V8. The active exhaust makes it even better, adding an aggressive exhaust note when you want it.
The AT4 is built for more than pavement. A factory 2-inch suspension lift, off-road suspension, automatic locking rear differential, Hill Descent Control, and red recovery hooks give this truck genuine capability for hunting trails, rough campsites, and challenging job sites.
One of the biggest upgrades is the CarbonPro Edition, featuring GMC's carbon-fiber composite pickup bed. Designed to resist dents, scratches, and corrosion, it's a premium feature that sets this Sierra apart from ordinary half-ton trucks. The black chrome grille accents, 20-inch machined wheels, and high-clearance running boards complete the aggressive appearance.
Inside, the AT4 Premium Package delivers heated and ventilated front leather seats, heated rear seats, premium Bose audio, and upscale Kalahari interior accents. The power sunroof, wireless charging, remote start, and power-sliding rear window add everyday convenience.
The Technology Package takes things further with a massive 15-inch Head-Up Display, Rear Camera Mirror, HD Surround Vision, and Bed View Camera. Additional safety features include Rear Cross Traffic Braking, Rear Pedestrian Detection, Trailer Side Blind Zone Alert, and front and rear parking sensors.
Towing equipment includes an integrated trailer brake controller, Hitch Guidance with Hitch View, trailer camera provisions, and GMC's in-vehicle trailering app. The MultiPro Tailgate Audio System by Kicker is another standout feature, perfect for camping, tailgating, or working outside.
Additional equipment includes navigation, rain-sensing wipers, LED bed lighting, premium floor liners, and 120-volt outlets in the cab and bed.
Finding an AT4 with the 6.2L V8, active exhaust, CarbonPro bed, Premium Package, Technology Package, and sunroof makes this a particularly desirable Sierra. It delivers the right combination of V8 performance, luxury, and off-road capability.
