2024 GMC Sierra HD In Flagstaff, AZ
Trim Levels
The exterior of the Sierra HD is strikingly assertive, featuring a robust front fascia complemented by GMC’s signature C-shaped LED headlamps. The grille varies across trims, from the ruggedly aggressive look of the AT4 to the sophisticated chrome finish on the Denali. Functional design elements such as corner-step rear bumpers, integrated bed steps, and the available MultiPro™ Tailgate offer a seamless blend of style and utility.
For those who favor adventure, the AT4 trim adds off-road-oriented touches like red tow hooks, skid plates, and black chrome exterior accents. Whether hauling equipment or exploring the wilderness, each trim delivers a distinct presence tailored to varied lifestyles.
Engine
For those seeking even more power, the available Duramax® 6.6-liter Turbo-Diesel V8 engine stands as a class leader in performance, producing an awe-inspiring torque output that makes towing heavy loads effortless. Paired with a 10-speed Allison® automatic transmission, the diesel engine offers seamless power delivery across the entire torque band.
Performance
For towing, the Sierra HD offers an array of technologies that make it exceptionally capable. Available Trailer Sway Control and Hill Start Assist provide stability on challenging inclines and during windy conditions, while the optional ProGrade™ Trailering System simplifies hitching and towing with a suite of intelligent features, including in-vehicle trailering app integration, multiple camera views, and trailer tire pressure monitoring.
Interior
The centerpiece of the Sierra HD’s technology suite is its high-resolution infotainment system, available in 8-inch or 13.4-inch touchscreens, with customizable driver information screens. These displays seamlessly integrate with wireless Apple CarPlay® and Android Auto™, allowing drivers to access music, navigation, and apps with ease. The available Bose® Premium Sound System offers a surround-sound experience, enveloping the cabin in crystal-clear audio.
Safety Features
Key features include the standard Forward Collision Alert, which detects potential frontal collisions and warns the driver, and the available Automatic Emergency Braking, which can engage the brakes if an imminent collision is detected. Lane Departure Warning and Lane Keep Assist are also available, gently nudging the vehicle back into its lane if unintended drifting is detected.
