Vehicle Description:
This 2019 GMC Sierra 1500 AT4 combines off-road capability, premium refinement, and everyday practicality into a rugged half-ton pickup. Finished in Summit White with Jet Black and Kalahari interior accents, the AT4 delivers a distinctive look with blacked-out trim, red tow hooks, and an elevated stance that sets it apart from standard Sierra models.
Powered by a strong 5.3-liter EcoTec3 V8 paired to an 8-speed automatic transmission, the AT4 provides confident acceleration, smooth highway cruising, and the towing capability expected from a modern GMC truck. The factory off-road suspension package adds Rancho monotube shocks, skid plates, hill descent control, a two-speed transfer case, and higher ride height for improved clearance on trails and rough terrain.
Inside, the cabin blends rugged design with upscale touches. Heated front and rear seats, a heated steering wheel, power front seats with lumbar support, dual-zone climate control, remote start, and premium materials make the AT4 comfortable for both daily driving and long trips. The Jet Black interior with Kalahari accents gives it a sporty yet refined atmosphere.
Technology is well integrated, with GMC’s Infotainment System featuring an 8-inch touchscreen, Bluetooth audio, Apple CarPlay and Android Auto, HD Radio, OnStar capability, and multiple USB ports. Additional conveniences include keyless entry, a power tailgate, rear vision camera, trailer brake controller, and a full suite of driver assistance features such as stability control, hill start assist, and tire pressure monitoring.
This truck also includes desirable option packages such as the AT4 Premium Package, power sunroof, upgraded 20-inch wheels with all-terrain tires, spray-on bedliner, and advanced trailering equipment—boosting capability and enhancing the premium feel of the vehicle.
Strong V8 power, a rugged off-road setup, premium interior comforts, and GMC’s signature refinement make this Sierra 1500 AT4 an exceptional choice for drivers seeking both adventure and daily usability.
