    Certified 2026 GMC Sierra 1500 4WD Crew Cab 147 AT4X *Ltd Avail* Preferred Equipment Group 4SG â€" EcoTec3 6.2L V-8 gasoline direct injection with variable valve control, cylinder deactivation, paired to a 10-speed automatic and producing 420 horsepower. This certified Sierra AT4X delivers robust V-8 performance for towing and daily driving, while fuel economy will vary by configuration; limited availability makes it a truck to see soon.

    Preferred Equipment Group 4SG brings a more polished presence and enhanced comfort to the Sierra, elevating the truck’s cabin atmosphere and on-road appeal without compromising its capability.

    Wireless Apple CarPlay and Android Auto let you mirror apps, navigation, and media without cords, so phone functions are seamless and distraction is minimized while you drive.

    Forward collision mitigation constantly watches the road ahead and can intervene to help slow or avoid a crash, adding a proactive layer of protection during busy drives.

    Front pedestrian impact prevention increases awareness in urban or crowded environments by detecting people ahead and taking steps to reduce the chance of a collision.

    A built-in mobile hotspot keeps passengers connected on the move, turning the truck into a convenient hub for streaming, work, or staying in touch without using phone data.

    The rear camera gives a clearer view behind the truck for safer backing, tighter parking, and easier trailer hookup, removing uncertainty when maneuvering.

    Lane departure prevention helps the truck stay centered by nudging the vehicle back into its lane when unintentional drifting is detected, helping reduce fatigue on long highway runs.

    Rear collision mitigation monitors the area behind you and prepares the vehicle if a rear impact risk appears, helping to protect occupants and reduce collision severity.

    Adaptive cruise control with traffic stop-go eases stop-and-go commuting by automatically maintaining a safe following distance and handling full stops and restarts as traffic flows.

    The head-up display projects key driving information onto the windshield so you can check speed and alerts without taking your eyes off the road.
