Description for 2024 GMC Sierra 1500 AT4 Crew Cab

The 2024 GMC Sierra 1500 AT4 embodies rugged capability and premium craftsmanship, engineered for drivers who demand both off-road performance and refined comfort. Finished in a bold exterior color that complements its commanding stance, the Sierra AT4 stands apart with its signature black chrome grille, body-colored bumpers, red recovery hooks, and aggressive LED lighting that give it an unmistakable presence. The exclusive AT4 badging, high-clearance front fascia, and 18-inch machined aluminum wheels wrapped in Goodyear Wrangler DuraTrac all-terrain tires emphasize its readiness for adventure. Functional features like skid plates, off-road suspension, and a two-inch factory lift deliver both form and purpose, making the AT4 as capable as it is stylish.

Under the hood, the 2024 Sierra AT4 offers power and versatility with a choice of advanced engines, including the standard 5.3-liter EcoTec3 V8 producing 355 horsepower and 383 lb-ft of torque, or the available 6.2-liter V8 with 420 horsepower and 460 lb-ft of torque. Both pair with a smooth-shifting 10-speed automatic transmission for optimal performance and efficiency. For drivers seeking diesel torque and fuel savings, the available 3.0-liter Duramax Turbo-Diesel inline-six generates 305 horsepower and an impressive 495 lb-ft of torque. Standard four-wheel drive, an automatic two-speed transfer case, and Hill Descent Control give the AT4 the confidence to handle rough terrain with ease. With a maximum towing capacity of over 9,000 pounds when properly equipped, this truck performs just as well at work as it does off the pavement.

Inside, the Sierra AT4 offers a premium cabin crafted for comfort and convenience. The interior features Jet Black leather-appointed seating surfaces with Kalahari accent stitching, blending ruggedness with sophistication. Heated and ventilated front seats, a heated steering wheel, and dual-zone automatic climate control ensure year-round comfort. The spacious Crew Cab configuration provides exceptional legroom and rear-seat comfort, while smart storage solutions like under-seat compartments and a large center console keep essentials organized. The attention to detail-soft-touch surfaces, authentic aluminum trim, and distinctive AT4 badging-creates an environment that's as refined as it is functional.

Technology in the 2024 Sierra AT4 is cutting-edge and intuitive. The centerpiece of the cabin is a 13.4-inch GMC Premium Infotainment System touchscreen with Google built-in, wireless Apple CarPlay, Android Auto, and voice-activated navigation. The 12.3-inch digital driver information center provides customizable performance data, while an available 15-inch multicolor Head-Up Display projects key information onto the windshield for easy viewing. A premium Bose sound system delivers concert-quality audio, and the available wireless charging pad, USB-C ports, and Wi-Fi hotspot ensure everyone stays connected. The innovative six-function MultiPro Tailgate and available CarbonPro composite bed offer unmatched functionality and durability for both work and recreation.

Safety and confidence come standard with GMC Pro Safety, which includes Forward Collision Alert, Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, and IntelliBeam automatic high beams. Additional available safety technologies such as Adaptive Cruise Control, Rear Cross Traffic Braking, and HD Surround Vision provide enhanced awareness in all driving conditions. The AT4's high-strength steel frame, advanced airbag system, and Trailer Side Blind Zone Alert further reinforce its safety credentials, ensuring peace of mind whether on the highway or the trail.
