Summit White 2021 GMC Sierra 1500 AT4 4WD
This 2021 GMC Sierra 1500 AT4 delivers a strong combination of off-road capability, premium comfort, and everyday usability in a full-size truck built for the Pacific Northwest lifestyle.
Powered by a 3.0L Duramax turbo-diesel inline-6 paired with a 10-speed automatic transmission, this Sierra offers smooth, efficient power delivery with excellent towing confidence and strong low-end torque. The AT4âs 4WD system, hill descent control, and auto-locking rear differential give it serious off-road capability while still maintaining refined on-road manners.
The AT4 trim stands out with its rugged yet upscale design, featuring red recovery hooks, a body-color surround grille, and a factory spray-on bed liner with AT4 logo. Itâs built to handle tough jobs while still looking sharp doing it.
Inside, the cabin blends durability with premium comfort. Heated and ventilated front seats, a floor-mounted center console, and premium interior touches create a refined driving environment. Power-adjustable seating and a quiet cabin make long drives and daily commuting equally comfortable.
Technology and convenience are well covered with keyless open and start, remote vehicle start, multiple USB ports, and a 4G LTE Wi-Fi hotspot capability. The HD rear vision camera and ProGrade Trailering System make towing and maneuvering more confident and straightforward.
With integrated trailer brake control, a trailering package, and a heavy-duty cooling system, this Sierra AT4 is fully equipped for hauling boats, trailers, and gear with ease.
Balanced between rugged off-road strength and premium everyday comfort, this Sierra AT4 is a capable and versatile truck built to handle work, adventure, and everything in between.
