2026 GMC SIERRA 1500 AT4 4WD 6.2L V8 CARBONPRO EDITION TECHNOLOGY PACKAGE SUNROOF STERLING METALLIC LANCASTER PA
This 2026 GMC Sierra 1500 AT4 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission, giving you 420 horsepower, strong naturally aspirated V8 performance, and the capability buyers expect from GMC's off-road-focused AT4. Finished in Sterling Metallic, this Sierra is loaded with the AT4 CarbonPro Edition, Technology Package, AT4 Premium Package, power sunroof, and Trailering Package.
The CarbonPro Edition is one of the features that really separates this truck from a typical Sierra AT4. Its carbon-fiber composite pickup bed is designed to provide excellent resistance to dents, scratches, and corrosion while keeping weight down. It's a premium feature that's useful whether you're hauling equipment during the week or loading up for a weekend away.
Under the hood, the 6.2L V8 is another big reason to want this Sierra. With 420 horsepower and 460 lb-ft of torque, it delivers the smooth response and unmistakable character of a big naturally aspirated V8. Add 4WD, off-road suspension, Hill Descent Control, an auto-locking rear differential, red recovery hooks, and high-clearance steps, and the AT4 has the hardware to back up its rugged appearance.
Inside, the Jet Black and Kalahari cabin features perforated leather with heated and ventilated front seats, heated rear seats, Bose premium audio, wireless charging, navigation, and a power sunroof. It's comfortable enough for long highway trips without losing the tougher personality that makes an AT4 different from a Denali.
The Technology Package adds some genuinely useful equipment, including a 15-inch Head-Up Display, HD Surround Vision, Rear Camera Mirror, and Bed View Camera. Those camera systems are especially helpful when parking, maneuvering off-road, or hooking up a trailer.
For towing, this Sierra is equipped with an integrated trailer brake controller, Hitch Guidance, Hitch View, in-vehicle trailering technology, trailer camera provisions, and Trailer Side Blind Zone Alert. GMC's MultiPro Tailgate adds even more versatility, and this one includes the Kicker tailgate audio system.
Finished in Sterling Metallic on 20-inch machined aluminum wheels, this is a sharp AT4 with an unusually strong combination of equipment.
If you're searching for a 2026 GMC Sierra 1500 AT4 6.2L V8 with CarbonPro, this one checks the boxes that matter: the big V8, CarbonPro bed, Technology Package, premium interior, sunroof, off-road capability, and serious trailering equipment.
