Description
2026 GMC Sierra 1500 AT4X:
- 6.2L V8 engine with 420 horsepower and 460 lb-ft of torque
- Dual active exhaust with sport-mode enabled
- Driver-selectable full-locking front and rear differentials
- Off-road suspension with hill descent control
- Bose Premium Series 12-speaker audio system with SiriusXM
- Premium GMC infotainment system with navigation and wireless Apple CarPlay/Android Auto
- 15-inch multicolor head-up display
- 16-way power driver and passenger seats with lumbar support
- Heated and ventilated front seats with heated rear seating
- HD surround vision with bed view camera and trailer camera provisions
- Automatic emergency braking with lane keep assist and rear cross traffic braking
- Power moonroof
- Spray-on bedliner with GMC logo
- Off-road high clearance steps
- 18-inch painted aluminum wheels
The AT4X trim elevates your Sierra with genuine wood dashboard and door panel inserts, full grain leather seat trim, and a leather-wrapped steering wheel that sets this truck apart from its peers. Power door locks, remote keyless entry, and push button start come standard, while the wireless charging pad and multiple USB ports keep your devices powered throughout the day. The integrated trailer brake controller and in-vehicle trailering system app make towing straightforward and confident.
Advanced technology enhances both safety and convenience on every drive. Automatic high-beam headlights, rain-sensing wipers, and the OnStar emergency communication system work together to keep you protected. The lane keep assist with lane departure warning and forward collision alert add another layer of confidence when navigating highways or city streets.
Off-road capability defines the AT4X experience. The hill descent control, driver-selectable locking differentials, and off-road suspension give you the tools to explore beyond paved roads with authority and control. The high clearance steps simplify entry and exit while the heavy-duty air filter and external transmission oil cooler support demanding terrain.
Inside, the cabin combines truck practicality with luxury appointments. Eight-speaker or available premium audio systems deliver quality throughout the cabin, while the floor-mounted center console provides organized storage. Climate control maintains comfort with automatic temperature adjustment, and the memory seat recalls your preferred driving position every time you climb in.
